Ceramic sand is very important oil fracturing agent, play a very important role in the oil extraction process. When oil and gas exploration in deep , high pressure low permeability deposit closure after fracturing treatment, the rock cracked petroleum , oil and gas from the cracks in the channel formed by the pooled out.
maide ceramic proppants sand used in fracturing in deep , it will be filled ceramic sand deposits in low permeability fractured rock in high closed fracturing treatment to split hydrocarbon formations , play a supporting fissure is closed not because of stress release , thereby maintaining high conductivity of oil and gas , ceramic sand will not only be able to increase oil and gas production , and more to extend the service life of oil and gas wells .
In general, the pressure along with ceramic sand was filled into the formation fracture in the formation , the crack does not play a supporting ceramic sand released and closed due to stress , thereby maintaining a high conductivity , so that gas flow, increase production.
Of course, the ceramic sand can also be played in many ways a very important role , the role of oil exploitation in the area is very large , but also we can not be ignored .

Ceramic proppant " sneak " the U.S. market
In recent years, the success of the U.S. shale oil and gas development , not only triggered a boom in exploration and development of shale gas resources worldwide , and many small manufacturing companies in China to create a great business opportunity.
Over the past three years , China 's maide ceramic proppant manufactured good support for its ability to gradually replace conventional proppant sand, into the U.S. market . So far, the Chinese -made ceramic proppant ceramic proppant has occupied the entire North American market share of 13% , the average annual business volume of $ 3 billion .
Shale oil and gas development is inseparable from the application of hydraulic fracturing , and hydraulic fracturing technology is the most important material is proppant . The purpose of the proppant in the oil pressure to open the high-pressure water layer prop open the crack pressure , so that the gas flows out .
In the past, U.S. companies used to make sand proppant . However, due to the sand into the deep well pump after easily crushed under high pressure formations , so more and more companies do tend to use resin coated ceramic proppant . But for those companies ( sand only 40 cents / lb ) are not willing to pay $ 4 / pound ceramic is concerned, more economical option is to use the child 's performance is better than conventional silica sand resin coating sand . As the number of drilling in North Dakota 's growing demand for sand is also increasing day by day , even from the state of Wisconsin and Minnesota looking for sand sources.
Since 2009 , North American demand for proppant almost tripled , as more and more companies are using multi- stage hydraulic fracturing , proppant demand grew by 10% to 15 %. Ceramic proppant with drilling companies need quality : size uniformity , chemical stability , high temperature high pressure , combined with good compatibility with sand , flowback easy to like. The main thing is not to deform under high pressure deep well , extend the productive life of oil and gas wells .
On the North Dakota prairie , the development of the Bakken Shale oil is very hot, the night from a satellite photo taken on the United States as evidenced by the recent North Dakota Bakken core group had deserted zone , night lights, no less bustling city . The state in October 2011 reached 48.8 million barrels of oil per day , sometimes a well requires 1,500 tons of sand and other proppants , of which ceramic proppant proportion reached 30%. Well here is often a depth of 10,000 to 12,000 feet , it is proppant best useless.
Over the past two years, the price increase is a large ceramic proppant , the U.S. domestic manufacturers have begun struggling to regain market . But with the rise of the Chinese domestic shale gas exploration and development , China 's ceramic proppant seem to have to worry about sales. In addition, the U.S. shale oil and gas development in the ascendant , from Ohio to Texas , shale oil and gas well drilling are heating up , the demand for ceramic proppant great , price increases have a certain tolerance.
Ceramic proppant production inputs is small, but highly profitable , Chinese proppant manufacturer's advantage lies in cheap local bauxite , bauxite is an important raw material for the production of ceramic .
Chinese proppant manufacturers sell their products directly to the Chinese oil service companies, such as Halliburton , Baker Hughes , Schlumberger , or through import and export companies , packaging will be shipped to the U.S. West Coast port their number , such as Long Beach , California or Seattle , Washington , and then transported by train in North Dakota and other places. According to North Dakota 's largest rail operator BSNF forecasts, ceramic proppant volume could double in 2012 .
A few months ago , North Dakota imported from China ceramic proppant ceramic production over the United States 20% cheaper . This difference has recently begun to shrink , with some of the middlemen involved in the future will further narrow the gap .
Since China began to develop its own shale oil and gas resources , the price advantage will be further weakened proppant . Recently, the China Petroleum and Shell to develop shale gas in Sichuan project progress , which means that China began commercial development of shale gas . Furthermore, the increase in production costs in emerging economies will also push up the price of proppant . Over the past two years , the price of Chinese ceramic proppant higher level rose by 60 % to $ 800 / ton. China will also exacerbate the current inflation proppant prices.
Nevertheless, the huge demand for North American ceramic proppant will provide enough space for all maneuvers . Chinese proppant company listed on the New York Stock Exchange , as long as oil and gas to maintain a certain price, they produce ceramic proppant on marketable .
Undoubtedly, prosperity proppant industry is another signal of U.S. shale gas development to the global spread of heat .

Oil fracturing proppant ceramic ceramic needs what
Fracturing technology is now widely used in oil exploration , the core technology is the formation fracturing diversion cracks and layer conductivity is much less than the diversion cracks. Now particulate
ceramic proppant is often added to the fracturing fluid , the aim is to make the fracture after the fracturing is still in an open state , resulting in a continuous oil product which is to obtain a high permeability fracture one of the important measures . In the application of deep well fracturing proppant performance requirements are very high , deep and strong chemical corrosive effect of salt solution and high thermal closure pressure , so you need to have a certain amount of proppant corrosion resistance and compressive strength . Proppant performance requirements of the main  |
( A ) a low density , to effectively improve the production efficiency ;
( 2 ) In a large injection pressure and friction when still produce artificial cracks. This requires support good resiliency and abrasion resistance , so that will not crack closure pressure is high and closed ;
( 3 ) to try to smooth and uniform particles , because smoothness and uniformity of the particles will affect conductivity .
( 4) The sphericity and roundness of particles that are greater than 0.9 , and a particle size in the range of between 0.4mm-0.8mm , the reason why this range is taken as the particle size to be well designed to meet the different requirements ;
5 ) To inexpensive to improve cost proppant ;
( 6 ) good acid resistance , acid solubility to less than 7% , as a proppant in the pressure and temperature of the fracturing fluid and the reservoir fluid and chemical reaction, if the lower the acid resistance , chemical stability of the proppant the worse , and they react more easily .

Resin coated frac sand companies
Resin coated proppant frac sand companies : pre-cured and cured . Precured resin coated Maide horizontal drilling have basically comprises the crosslinked resin-coated substrate. Pre -cured resin coating proppants provides crush resistance to the substrate. Since the oil was added before the resin -coated proppant is already cured layer , even under high temperature and pressure conditions are not blocking the Shale gas revolution.Such precured resin coated proppants by stress generally maintained around the well . Hydraulic fracturing in some environments, especially in the oil / gas production or cleaning process, the pre -cured well proppant flow back from the fracture . Some of the proppant from the wellbore fluid can enter the well with the generation of cracks area.
