At present, the domestic hydraulic fracturing proppant use of fracturing ceramic, quartz sand, but their strength is relatively low, only for the exploitation of shallow wells. If these proppant for deep, it is difficult to bear enormous rock pressure, it will cause a lot of fragmentation, not only can not make the oil yield but preventing oil outflow. The current domestic proppant for deep wells will need to be imported from abroad, domestic production can not. Which virtually increases the cost of production, so the domestic eager to produce its own high-strength proppant Hydraulic Fracturing Proppants fracturing of oil for deep mining field. In this experiment, bauxite, kaolin burned as the main raw material, auxiliary materials, iron oxide, burnt dolomite, manganese, made under laboratory conditions of high strength proppant fracturing of oil.

frac proppant

Proppant is a ceramic granular frac proppant 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 proppant 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.

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.

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.

Oil fracturing proppant In addition to a small amount of tungsten heating

In addition to a small amount of tungsten heating material for high temperature furnace, heater tubes and composite reinforcement endures, most of them are used for the Resin coated ceramic proppant production of whiteTungsten wireFilament incandescent lamps and halogen and gas discharge lamp electrodes. Cathode gas discharge lamp for use as tungsten or tungsten rods, in order to reduce its electron work function, shall be added
0.5-3% thorium, tungsten thorium called wire. Since Thorium is a radioactive element, pollute the environment, it made a useful cerium tungsten thorium instead of cerium cerium tungsten wire or rod. But ceriumEvaporation rate, so that a tungsten filament or tungsten, cerium Ce can be used for small power pole gas discharge lamp.Once the use of tungsten at high temperature recrystallization becomes very brittle in case of a shock or vibration can easily break. In some of the requirements of high reliability electric light Ultra lightweight proppant in order to prevent breakage of the filament, often in the tungsten doped with 3 to 5% of rhenium, tungsten, rhenium wire is called, it can make the tungsten brittle transition temperature down to the extension at room temperature

Ceramic proppant

In effect the success of resin coated sand proppant , the effective length depends primarily on the quality of the proppant. The role of fracturing proppant that produce hydraulic fracture filling, so that it becomes closed again, and the ability to form a crack diversion has the ability to get the stream. Fracture conductivity is the ability to transport crack spread reservoir fluids, and propped fracture permeability and fracture proppant closure wide representation of the product is generally believed that the type of proppant in the fracture and the physical properties of distribution and fracture closure pressure is the main factor controlling the fracture conductivity. Thus, the physical properties of palm Resin coated ceramic proppant and fracture conductivity affected by many factors, there is a reasonable choice in favor proppant fracturing fluid and conducive to fracturing proppant material made more precise requirements.
