Oil and gas wells in conductivity after fracture stimulation effect and its production performance depends on crack, crack conductivity is the ability to crack the conductive fluid within the reservoir to ceramic proppant supplier fracturing proppant permeability and fracture width of fracture support product to represent. Thus, the type and distribution of the physical properties of the proppant in the fracture is an important factor affecting the ability of fracture conductivity.
Performance requirements of oil fracturing proppant follows:
1, proppant have sufficient compressive strength and wear resistance, can withstand strong pressure and friction during injection and effectively support the artificial cracks.
2, proppant particles relative density is lower, easy pumped underground.
3, proppant particles under conditions of a temperature of 200 degrees, with the fracturing fluid and the reservoir fluid is not a chemical effect, the acid solubility of the maximum permissible value should be less than 7%.
Furthermore, we hope adequate supply, low prices.
Oil well fracturing construction costs need to spend hundreds of thousands, even hundreds of million, the proportion of the cost of proppant in which accounts are not large, however, the effects of quality proppant fracturing plays a crucial post the role of a direct impact on the net income of oil production.
Proppants currently used quartz sand, ceramic and a variety of resin-coated composite particles. Wherein the quartz sand cheapest price, relatively low density, to facilitate the construction of pumping, so it is widely used, but low-intensity quartz sand, the ball is poor, thereby reducing the conductivity of cracks, particularly closure does not apply to high pressure The deep, with a composite resin coated quartz sand particles, the sphericity improved corrosion resistance can achieve higher targets, even if the internal quartz sand is crushed, outside coated resin layer can wrap pieces, keeping the crack diversion capacity, is a development direction proppant, but the current product shelf life is relatively short, the cost is also high, with a variety of different materials and manufacturing process of ceramic, slightly higher than the relative density of quartz sand, conditions and performance of pumping fracturing fluids are more demanding, more difficult when fracturing, fracture stimulation

but the ball and roundness Ceramisite than quartz sand, and can reach 0.9 or more, particularly resistant resistance, temperature resistance and compressive strength are higher than quartz sand, thus decreasing conductivity fracture is much lower now increasingly widely used oil and gas fields.
