Preparation of ceramic proppants

Ceramic proppant manufacturers man-made ceramic proppant traditional method of preparation agents mainly bauxite and fluxing phase (such as manganese ore) with a certain proportion, crushed grinding (particle size of 300 mesh), the disc granulator granulation step was prepared by raw material ball, high temperature sintering of medium or high density ceramic proppant. Through the oil shale residue, bauxite and fluxes in proportion with, crushed by disc granulator granulation was prepared by primer raw material ball, and then after high temperature sintering a low density ceramic proppant. China proppant oil shale residue is waste oil shale oil shale refining later.

Cumulative oil shale residue accumulation would take a lot of land, but also endanger the health of residents; the pollution of heavy metals in the process is a lot of oil shale residue contains, after rain leaching or diffusion of serious pollution to the surrounding water, land, poisoning of land, acidification, the destruction of soil productivity, disruption of agricultural production, to the detriment of health of the residents. But oil shale residue contains large amounts of mineral components, such as quartz, feldspar, clay and other ingredients, after firing the distillation, the structure is very loose, very light density, the larger the loss on ignition. Man-made ceramic proppant prepared and coated ceramic proppant use oil shale residue, not only can reduce the accumulation of oil shale residue on a lot of land occupation, to eliminate a serious threat to the environment, ecology and human health, but also can improve oil use value shale slag.

Proppant is a ceramic granular product can be widely used in deep

Frac proppant it can be used in fracturing in deep, high-pressure oil and gas layers. High-quality bauxite, the raw material for the king to be finely ground into fine powder after crushing, with various additives, repeatedly kneading, granulation, polishing. High temperature sintering, proppant supplier The product has high strength, low density, good ball, finish high, strong conductivity and so on. By the China Research Institute of Petroleum Exploration and Development, Langfang Branch support evaluation laboratory testing, the performance indicators fully meet SY / T5108-2006, SY / T6302-1997 standard, currently in the lead.

Fracturing proppants is a ceramic granular product with high fracture strength, mainly used in oil well supported, to increase production of oil and gas, an environmentally friendly product. This product is the use of high-quality bauxite and other raw materials, sintered ceramic, is a substitute for natural quartz sand, glass beads, metal balls and other low-strength proppants to increase oil and gas has a positive effect. When oil and gas exploration in deep, high pressure low permeability deposit closure after fracturing treatment, the hydrocarbon-bearing formation split, passage of oil and gas from the cracks formed in the collection out. Ceramic proppant material along with high-pressure solution is filled into the formation in rock fissures, cracks do not play a supporting closed due to stress release effect, thereby maintaining high conductivity, so that oil and gas flow, increase production. Practice has proved that the use of ceramic proppant fracturing wells can increase production by 30-50%, but also to extend the service life of oil and gas wells.

Proppant substantial increase in oil and gas production and extend well life

Frac proppant of natural sand with a certain size and grade distribution or man-made high-strength ceramic particles. Ceramic proppant ceramic proppant bauxite as raw material by powder granulation, sintering, high temperature, high pressure, corrosion resistance, high strength High conductivity, low density, low breakage rate and other characteristics, the most widely used. In the resin-coated sand or ceramic surface, can further improve the strength and conductivity properties of the proppant.

China proppant and supported by the fracturing fluid into the formation of cracks in the fracture, thereby effectively import oil and gas wells, a substantial increase of oil and gas production and extend well life.
Expected in the next few years, China's oil fracturing proppant industry will rapidly expand the size of the market, the rapid increase in the total capacity of the enterprise. Oil fracturing proppant products in the direction of high-strength development. Moreover, the product will trend toward more segmentation, product line will be further enriched. China's oil fracturing proppant market size will be rapid development, the annual growth rate of more than 27%. 2012 oil fracturing proppant market size growth rate 29.23%, the market size of about 2.74 million tons.
