The performance requirements of petroleum proppant

A Maide low density proppant have sufficient compressive strength and resistance to abrasion, resistant to strong pressure and friction time of injection, and effectively support the artificial cracks.
2, the relative density of the hsp proppant particles must be low, to facilitate pumped downhole.
3, proppant particle diameter wells to meet different design requirements, typically 0.4 ~ 0.8mm, roundness and sphericity of greater than 0.9, and particle uniformity, smooth surface, the haze value should be less than 100 degrees in order to obtain the highest possible diversion capacity.
4, the proppant particles in a temperature of 200 degrees Celsius, the fracturing fluid and the reservoir fluid is not a chemical effect, the solubility of the acid should be less than the maximum allowable value of 7%.

The end to take off the sand fracturing technology

With the development of oil and gas drilling technology and a variety of the intersection of the integrated use of technology, fracturing technology application range is no longer confined to low permeable formation, middle and high permeable formation also began to use the technology to resin coated ceramic proppant development effect. When fracturing technique is applied to the high permeability formation, hope to form a short and wide fracture, and the crack control as much as possible in the range of oil and gas layer. Abroad in order to meet the special requirements, in the mid - 1980 - s end sand fracturing technology, is developed and applied to the scene quickly, the current domestic also conducted the research, and has made great progress.

Proppant fracturing a direct impact on the quality of petroleum oil revenue

Maide fracking process oil well construction costs need to spend hundreds of thousands , even hundreds of million , the proportion of the cost of oil proppant production line in which the share is not large, however , the quality of the proppant fracturing effect plays a crucial post important role in the direct impact of net income of the production wells . Proppant production lines have sufficient compressive strength and resistance to abrasion , resistant to strong pressure and friction time of injection , and effectively support the artificial cracks. Oil fracturing proppant particles relative density is lower , easy pumped underground.

Now Maide petroleum proppant production lines are becoming increasingly popular at home and abroad , mainly due to superior product performance . New Chemical Materials weaker dependence on oil and gas resources of traditional petrochemical materials, cyclical obvious. Development of organic fluorine , silicone materials have certain advantages in resources ; technical barriers, industry concentration is high. High value-added products , industry profitability than traditional chemical . Petroleum proppant production compared to other devices , has strict performance requirements.

Oil fracturing proppant particle diameter wells to meet different design requirements , typically 0.4 ~ 0.8mm, roundness and sphericity of greater than 0.9 , and uniform particle surface is smooth , the haze value should be less than 100 degrees in order to obtain the highest possible high conductivity . The oil fracturing proppant particles at a temperature condition of 200 ° C , with the fracturing fluid and the reservoir fluid is not a chemical effect , the solubility of the acid should be less than the maximum allowable value of 7% .

Oil fracturing proppant ceramic sand production line bearing in terms of its role is mainly used to support but that the literal interpretation is used to bearing shaft is only part of its role in supporting its essence is able to bear radial load can be understood as it is requirements for fixed shaft axis is fixed to the shaft so that it can only achieve rotation and control its axial and radial movement of the motor is not working because the consequence is simply not possible movement of the shaft and the motor work in any direction bearing only rotation .

Oil fracturing proppant application must meet the following performance requirements:

( 1 ) High  strength. Ensure high closing under pressure to get the most effective support can still crack . And different types of ceramic proppant composition , different intensity , the higher the intensity , the greater the pressure capacity .
( 2 ) particle size uniformity, sphericity . Proppant can improve the bearing capacity of uniform size and permeability of the proppant . The proppant particle diameter is generally used currently 0.45 ~ 0.9mm ( i.e. 40 / 20 mesh ) , sometimes with small diameter 0.9 ~ 1.25mm ( i.e., 20/16 mesh) .
( 3 ) less impurities . To prevent blockage of the pores and reduce support crack fracture conductivity . Fracturing sand impurities is the mixed carbonate sand , feldspar, iron oxides and clay minerals ; a marine acid solubility to measure the presence of carbonates in the fracturing sand , feldspar and iron oxide content ; measure turbidity levels present in the frac sand clay , silt or inorganic material particles.
( 4 ) a low bulk density is preferably less than the density of 2000kg/m3, to facilitate delivery of fracturing fluid and proppants effectively filling cracks.
( 5 ) High brine chemically inert , does not react with the fracturing fluid and the reservoir fluid , to avoid contamination propped fracture ;
