The primary composite proppant particles

Proppants currently used mainly Proppant quartz sand, bauxite and ceramic sand and resin-coated composite particles. Due to the low cost quartz sand, while low density easy pumping, is widely used, but quartz sand strong low end, the ball is poor, reducing fracture conductivity, does not apply to closed high pressure deep well. Resin composite particles coated quartz sand, sphericity improved corrosion resistance strong, conductivity is also good, but the products remain short-term, the cost is too high, the cost-oriented promotion today is not easy, and the use of bauxite ceramic proppant ceramic technology, high density, good sphericity, corrosion, high temperature, high pressure, while the costs can be better controlled, and therefore more and more widely used in oil and gas fields. Practice has proved that ceramic proppant the use of ceramic proppant fracturing of oil wells can increase production by 30-50%, but also to extend the service life of oil and gas wells, a key material in the oil and gas wells in low permeability oil and gas extraction, construction, not only to increase oil and gas production, and can extend the service life of oil and gas wells.

Proppant development well

With the rise of shale gas exploration Low density proppant and development in China, China's ceramic proppant will usher in greater market development. The past two years, price rises ceramic proppant large increase in production costs in emerging economies will push up the price of proppant. Since the production of bauxite is an important raw material of ceramic, although China has the advantage of cheap local bauxite, but with the advance of China's rare earth ore strategy, future prices will keep rising, so there is a certain ceramic proppant price increases.
Meanwhile, China's ceramic proppant manufactured with good support capabilities, gradually replace the conventional proppant sand, into the US market. Data show that China-made ceramic proppant has occupied 13% of the total ceramic proppant market share in North America, the average annual business volume of $ 3 billion. Currently, the US shale oil and gas well drilling is entering the heating up, the demand for ceramic proppant great, price increases also have some tolerance. As long as oil and gas to maintain a certain price,Proppant China's production of ceramic proppant in the United States and other countries would be marketable.
At present, the research and development of Chinese ceramic proppant fracturing of oil well, showing good momentum of development. The future, the industry can continue to support high-strength oil fracturing support agent special ceramic materials and products technical development, focusing on the development of oil fracturing support agent products.

Proppant huge market space

After oil and gas exploration China proppant wells over time, high closure pressure after fracturing low permeability deposit processing, the hydrocarbon formation split, passage of oil and gas from the cracks formed in the collection out. Ceramic proppant material along with high-pressure solution is filled into the formation of cracks in the rock, the crack does not play a supporting closed due to stress release effect, thereby maintaining high conductivity, so that oil and gas flow, increase production.
Widely used in ceramic proppant oil and gas operations, the increase in oil and gas production, because the quality of different ceramic, its role is not the same. Shale, flowers and other ceramic proppants ultra-light ceramic mainly used for decoration, concrete and other industries; dense, low breakage rate ceramic mainly used in petroleum industry, as proppants used. Ceramic proppant technology has made great progress in recent years.

Support for oil products in the ceramic proppant country is currently in its infancy, most manufacturers can only produce medium and low intensity of products, most of granulation equipment with dozens of aircraft icing, more employment, dust, high production costs, plus labor unstable operation quality, low production efficiency, to meet the needs of international and domestic markets. The original instrument of labor and the corresponding monitoring and control system there is a big flaw in the technology, production caused great waste. Chuzhou, China Metallurgical and Mechanical Technology Limited in QPY type form the basis of the ball machine, and the rule of powder into a ball joint R & D center constantly sum up innovation, optimize the process route, completely solve the granulation automatic integration into a ball (feed water tracking Automatic granulation technology) the technical ceramic proppant manufacturers problems, significantly reducing the granulation workers, saving production costs, reduce labor intensity and reduce dust pollution and improve production efficiency. Related ceramic sand production line equipment is being declared national patent. QPY-Ⅱ-type oil proppant (ceramic sand) dedicated to the ball granulation equipment. Completely changed the oil proppant (ceramic sand) industry with more than sugar-coated pan granulation and dusty history.

Ceramic proppant sphericity, high strength, corrosion resistance, strength

Fracking process Hydraulic fracturing technology is an effective technology fields to increase production. The process is to use high-pressure pump on the ground, the high viscosity of the fracturing fluid to significantly exceed the absorptive capacity of the formation of the displacement is injected into the well at the bottom Biechu high pressure; frac proppant when the pressure is greater than the near wellbore formation rock formation stress and tensile strength, at the bottom near the ground will crack; Fracturing proppants continue to inject liquid with sand proppant, fracture proppant filling extending forward and, after shut-filled fracture closure on the proppant, the last in the vicinity of the bottom cracks with a geometry and conductivity of a formation to facilitate a faster inflow of crude oil around the bottom of the well, to achieve the purpose of increasing production. As hydraulic fracturing proppant filling an important medium, which directly affects the capacity of the entire yield wells. Therefore, the study of high performance oil proppant for oil yield is very necessary. Oil fracturing proppant * Major points of natural quartz sand,

artificial ceramic proppant, resin-coated proppant (ie coated proppant) three categories, including coated proppant is divided into two coated sand and ceramic coating species. Natural quartz sand is not good for its sphericity, low intensity, but the lowest cost, it is generally in the large-scale use in shallow; artificial ceramic proppant due to its sphericity, high strength, corrosion resistance, good conductivity etc., as it has been widely used in the deep fracturing. Since the resin-coated sand after coating strength, density becomes small, can replace ceramic proppant oil in a medium-depth, but few studies coated ceramic proppant, the higher the cost, and could not be used Actual production

Artificial proppant and ceramic proppant compared

a)ceramic proppant supplier high artificial proppant relative particle density, such as: quartz sand is 2.60 g / cm3 ~ 2.70 g / cm3, but ceramic sand is of 2.80 g / cm3 ~ 3.60 g / cm3. Therefore, the performance of fracturing fluid (such as viscosity, rheology, etc.) and pumping conditions (such as displacement, power equipment, etc.) have put forward higher requirements. Ceramic proppant manufacturers

 b)Ceramic proppants the relative density of the particles depends on the material and the compressive strength of aluminum oxide content. With the increase of the content of aluminum oxide, ceramic of high density, compressive strength increases, so the two should get a balance. On the other hand, under the same conditions as the aluminum content of materials, processing technology (powder fineness, semi-intensity, sintering temperature) is the key to controlling the ceramic quality. Therefore, ceramic materials selection and manufacturing processes than other proppants demanding, much more complex.
 C) artificial ceramic proppant relative wear, high price.

Development proppant production

Fracture stimulation of oil and gas wells in low permeability oil and gas extraction yield important new technology. Proppant is the fracturing of key materials.

In recent years, as domestic oil fracturing proppant manufacturing Development, proppant fracturing of oil export volume gradually from scratch, from less to more. However, overall, the export volume is still less than imports. And products are mainly concentrated on low value-added low-end products, imports are high value-added high-end products, such as the excellent performance of high strength proppant fracturing of oil products. Development of oil fracturing proppant industry is not fast, the market size of the average annual growth rate of about 15 percent, the average annual growth rate of the enterprise total capacity of around 12%. Large number of enterprises, but most are small businesses, low yield, low-tech, competition means also focused on product prices above, and do not occupy a larger share of the market, especially large-scale enterprise production. Domestic oil demand continues to increase dependence on foreign oil continues to increase. In order to meet the increasing domestic demand for oil, the oil industry has developed rapidly. Correspondingly related products is rapidly expanding. China's oil fracturing proppant industry at this time, the relatively rapid development, the market scale growth rate reached 20%. In 2009, China oil fracturing proppant industry investment amount 470 million yuan in 2011 increased to 620 million yuan, an average annual growth rate of 13% the above.
