When it comes to the difference between the ceramsite equipment and ceramsite sand equipment, we must talk about the equipment to produce frac sand companies and ceramsite sand: the difference between the particle size, particle than ceramsite ceramsite sand particles is much larger, ceramsite grain size is usually 5 ~ 20 mm, the biggest can reach 25 mm, ceramsite are commonly used to replace the gravel and pebbles in concrete; And ceramsite sand is a kind of ceramic particle products, fineness of grain size is much smaller, and has the very high fracturing strength, mainly used for oil well under oil fracturing proppant, in order to increase the output of oil and gas, belongs to the environmental protection product, specific can see: oil fracturing proppant production process. From the raw material, no difference with ceramsite ceramsite sand, frac sand is also same, does not use the technology and equipment of discharging size is slightly different. Remember the last time send the site to a consulting ceramsite equipment customers, customer should say your website is ceramsite sand equipment, no ceramsite equipment, actually the difference between both devices are small, so the customer can visit our kaiyuan machinery ceramsite sand equipment project network time to pay attention to, this site related words are: ceramsite, ceramsite production line equipment, ceramsite sand equipment, ceramsite sand production line, etc., about my company to the customer to do case, can see: ceramsite sand equipment successful cases. Process, for example, 80 ~ 80 cubic ceramsite sand equipment used are: jaw crusher, ceramsite sand mill, mixer (with chrome), (optional) adhesive mixing barrel, the double helix conveyer, strong pressure ball machine, when output is large, using ceramsite sand pelletizer is used when the FU chain conveyor.

The purpose of the ceramsite

Ceramsite has excellent performance, such as low density, high cylinder pressure strength, high porosity, high softening coefficient, good frost resistance, resistance to JianJiLiao excellent reactivity, and so on. Especially frac sand of the ceramsite density is small, internal porous, morphology, composition is uniform, and with a certain intensity and strong, thus has light weight, corrosion-resistant, antifreeze, and other multi-functional characteristics of seismic and well insulated. Using ceramsite these excellent performance, it can be widely used and building materials, gardening, food and beverage, fire-resistant insulation materials, chemical industry, petroleum and other departments, application field is more and more widely, and is still rising. At the beginning of the ceramsite invention and production, it is mainly used in building materials field, due to the continuous development of technology and people to know more deeply, the fracturing proppant of the ceramsite ceramsite already more than building materials this traditional scope of application of expanding its application in new areas. Applications of ceramsite in building materials, now has fallen to 80%, from 100% in other aspects of the application, has accounted for 20%. With the continuous development of new application of ceramsite, it will gradually increase the proportion of in other ways. Particles is all over the world to get fast development, because it has other materials do not have many excellent properties, the excellent performance, the excellent performance make it has the effect cannot be replaced by other materials. These excellent performance has the following several aspects. Density is small, light ceramsite its bulk density is less than 1100 kg/m3, generally is 300 ~ 300 kg/m3. Made with ceramsite as aggregate concrete density is 1100 ~ 1800 kg/m3, the corresponding concrete compressive strength is 30.5 ~ 40.0 Mpa. The biggest characteristic of ceramsite is appearance is hard, and there are many pores inside. These microporous give the haydite lightweight properties. 200 lytag concrete density is about 1600 kg/m3, and the same label of the density of ordinary concrete is up to 2600 kg/m3, both differ 1000 kg/m3. Heat preservation, heat insulation ceramsite due to internal porous, so has good insulation, the thermal conductivity of concrete prepared with it, as a general rule, be 0 ~ 0.8 W/(m, k), 1 ~ 2 times lower than the normal concrete. So, ceramsite architecture has good thermal environment.

Hydraulic fracturing is to use the ground high pressure pump

Hydraulic fracturing is to use the ground high pressure pump, through the wellbore to squeeze oil layer with high viscosity of frac sand fluid. When the injection rate of fracturing fluid exceeds the absorptive capacity of the reservoir, the reservoir is formed on a high pressure on bottom, when the pressure is more than near the bottom of a well fracture pressure of reservoir rocks, reservoir pressure will be open and cracks. Then, on and on to reservoir squeeze fracturing fluid, cracks will continue to expand inside the reservoir. To keep the pressure on cracks in the open state, then to the reservoir into with proppant carrying fluid (usually quartz sand), after carrying fluid into the cracks, cracks on the one hand, can make its way, on the other hand can have open cracks, so that it is not closed. Then into the displacement fluid, the carrying fluid of wellbore entirely replace into the cracks, prop up the cracks with quartz sand. Finally, the injection of high viscosity fluid will fracturing proppant degrade the discharge shaft, left one or more of the oil length, width and height of crack and reservoir and established a new fluid passage between the wellbore. After fracturing, the output of oil and gas Wells are generally increase substantially. It can be generated in various stages of organic origin on the subject of natural gas in free phase (about 50%), very little stored in dissolved state in kerogen, asphalt and oil. Natural gas are also present in the interlayer of siltstone, silty mudstone, argillaceous siltstone, sandstone formation even. After gas generated in the source rock in the nearby gathered themselves together, and show the typical shale gas on the patterns of in situ, with a greater difference between shale, tar sands, asphalt, etc. Different from conventional gas reservoir, shale is gas generation of source rocks, and gather and save gas reservoir and cap rock. As a result, high organic matter content of black shale, such as high carbon mudstone is often the best conditions for shale gas development

Fracturing proppant is a kind of ceramic particle product, has the very high fracturing strength

Fracturing proppant is a kind of ceramic particle product, has the very high fracturing frac sand, mainly used for oilfield downhole support, in order to increase the output of oil and gas, environmental protection products. This product use high quality bauxite and other raw materials, ceramic sintering and become, is a natural quartz sand, glass balls, metal balls substitute for middle and lower strength proppant, to produce more oil and gas has a good effect. Oil and natural gas deep well drilling, high closure pressure and low permeability ore deposit after fracturing treatment, split oil and gas layers, oil and gas from collecting in the crack formation of the channel. With ceramsite support material with high pressure solution into the strata filling in rock fractures, supporting crack because of the action of stress release and closed, so as to maintain a high diversion ability, make the oil and gas flow, increase production. Practice has proved that using ceramsite proppant fracturing of oil Wells can improve the production of 30-50%, still can prolong oil and gas well service life

Fracturing proppant can be widely used in deep well, high pressure oil and gas layer fracturing. By the high quality bauxite as main raw materials made of fine ground into powder, match with various additives, fracturing proppant practice, granulating, polishing, high temperature sintering, the product has high crushing strength, low density, good sphericity, high smoothness, diversion ability, etc. Supported by the oil exploration and development research institute of China langfang branch evaluation laboratory tests, each performance index of SY/T5108-2006 completely, / T6302-1997 standards, is at a leading level hydraulic fracturing (hydrofracturing method), also known as hydraulic fracturing method. An absolute stress measuring method. When measuring the first take a bedrock exposed drilling, sealed on both ends up and down with the packer, Pressure and injection liquid, until hole wall burst, and record the pressure changes over time, and using the mold or downhole television observation fracture azimuth. According to the record of pump pressure and the fracture azimuth, fracture pressure and close using the corresponding formula to calculate the stress size and direction of the landlord.
