Frac sand companies produce liquid at temperatures lower

Fired frac sand companies production is most important a process, have a great impact on their microstructure and macroscopic properties. After determining the ratio of the specimen, it will produce a fine powder in the firing process at a lower temperature between the liquid phase, but also to frac sand companies and petrochemical reactions corundum frac proppant crystal form transition occurs, and therefore the firing temperature must be controlled so that maintained within the optimum temperature range to ensure after the firing has excellent frac sand companies overall performance. If the temperature is too high there will be over-burning phenomenon, and ferric oxide (Fc203) of content. After the surface of a liquid phase, the oxygen diffusion to the center fracturing proppants of the block, this time occurs Fe203 = 2Fe0 + I / 20z reactions. Since the volume of the frac sand companies strength and the effect of the density of the reaction products are reduced. If the calcination temperature is too low due to burning phenomenon occurs due to insufficient sintering, its intensity is reduced. Firing temperature has little effect on the bulk density, but has a greater impact on the frac sand companies High crush proppants crushing rate and the acid solubility. Minimum firing temperature corresponding crushing rate of 1360 ℃, while the corresponding acid solubility best when firing temperature is 1350 ℃. Therefore, in order to obtain the desired combination of properties, the firing temperature must be between 1350-1370 ℃; producing a frac sand companies to the firing temperature should be controlled at about 1360 ℃, the solubility of the acid <5%, to meet the Claim.

Ceramic proppant is the key material mined fracturing

Ceramic proppant oil, a key material of low permeability gas exploration fracturing oil and gas wells, in good macroeconomic policy, ceramic proppant products in the future exploration and development of oil and gas wells in applications will be more widely used , Ceramic proppants in line with national industrial policies. Accelerate local economic development, through the development of energy, increase investment, the development of new application technology, led a complete industrial chain of circular economy and building a harmonious society has become the primary task of the various local governments. Ceramic proppant has played an important role in the application of oil and gas wells, not only to increase oil and gas proppant conductivity production, and can extend the service life of oil and gas wells. Therefore, from the ceramic proppant developed technology, the practical application point of view, there is a very good market space, in line with the relevant policies of local governments.Ceramic proppant is a ceramic particle product with high fracture strength, mainly for oilfield downhole support, to increase production of oil and gas, an environmentally friendly fracture stimulation. Ceramic proppant is the use of high quality sintered bauxite and other raw materials, is a substitute for natural quartz sand, glass beads, metal balls and other low-strength proppant, to increase production of oil and gas have good results. When oil and gas exploration in deep, high pressure low permeability deposits closed after fracturing treatment, the rock cracked petroleum, oil and gas channel formed from the cracks in the collection out.

Proppant most widely used

Proppant fracturing fluid into and supported by fracturing the formation of cracks, thereby effectively import of oil and gas wells, a substantial increase oil and gas production and extend well life. Structural performance Proppant to have a certain size and grade distribution of natural sand or synthetic high-strength ceramic particles. chinese proppant (ceramic proppant) with bauxite as raw material by powder granulation, sintering, high temperature, high pressure, corrosion resistance, high strength, high conductivity, low density, low breakage rate, etc. , the most widely used. In the resin-coated sand or ceramic surface, it is possible to further improve the strength and conductivity properties of the ceramic proppants.especially large-scale enterprise production. Domestic demand for oil 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 suppliers industry at this time, the relatively rapid development, market growth rate reached 20%. 2009, China's oil fracturing proppant industry investment amount 470 million yuan, in 2011 increased to 620 million yuan, an average annual growth rate of over 13%.
