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 .

Cementing casing ten dozen grade Fracturing

This is the most commonly shale formations way ( see Figure ^ ) ) . When completions , the first of the horizontal wellbore casing cementing , and implementation of the " bridge plug ten perforation " multi -stage fracturing , which achieved mechanical packer inside the casing through the cable coiled tubing packer or bridge plug proppants for hydraulic fracturing  by solid well realize annulus mechanical steering . This process is then repeated to complete the multi-stage fracturing in horizontal section . When all the small pieces to be dealt with, in addition to the use of coiled tubing drilling composite bridge plug so that the horizontal wellbore re- connected from the heel to the end and put into production. Although this approach can achieve the level of sub- section steering transformation, but at every level have to use coiled tubing , perforating guns and fracturing equipment for proppant suppliers operations, production costs are very high, and low operating efficiency , time-consuming . Studies have shown that the yield obtained using this method is also not ideal, because cementing will block many natural cracks and joints , and these cracks and joints are very important for improving gas production.
