Ceramsite proppant performance test

The use of omec particle size analyzer (LS-POPIV) size of the test material, Holland 'panalytical production company X Pert type PRO X - ray diffraction phase analysis of samples, the Japanese JSM-6380LV scanning electron microscope (SEM) on the surface morphology of the samples were microscope observation.

  According to the national standard GB/T3810.3 - 1999 test water absorption of ceramic proppant rate (W), press (a) formula.

w = (m1-m0)/m0 ×100%                   (a)

M0, M1 as the quality of samples when dry and immersion after saturation
the unit is g.

Preparation of alumina industry of high alumina ceramic proppant

Study on Preparation of ceramic proppanthigh aluminum alumina industry, there is still no domestic reports. In view of the above situation, the urgent need to develop the domestic high-grade ceramsite proppant yourself.

  In this paper, taking alumina as main raw material, adding proper amount of auxiliary materials, through experiments in the laboratory, system.

  The preparation of high alumina ceramic proppant, research on haydite proppant added the sintering temperature, particle size of raw material, additive -BaCO3
effect of performance.

Ceramsite proppant performance needs

At present, the domestic production of ceramic proppant is with bauxite as main raw material to prepare the products, acid resistance, crush resistance difference.

  The best performance of the blowing ceramsite propping breaking agent under the 69MPa rate was 2% ~ 4%, the acid solubility ranged from 3% to 5%, it is difficult to meet the Tahe oilfield fracturing and acidizing technology requirements.

  For Tahe reservoir UHP reservoir reformation of proppant, are high-grade production using alumina as main raw material,domestic products, temporarily unable to produce, mainly depends on the America imports, the price is quite expensive (about 7500 ~ 15000 yuan / ton, while the cost is less than half of this price).

Ceramsite proppant, production method

ceramic proppant is oil, natural gas extraction in the process of fracturing operation to support the solid particles of rock joints with certain strength.

  During the fracturing operation process, proppant mixed with fracturing, using high pressure means will be injected into the deep rock crevices, forming high permeability channel, so that the oil or gas outflow from the cracks.

  The practice proved that, the use of high aluminum proppant fracturing wells can increase the yield of 30 ~ 50%, the service life can be extended well.

Preparation of samples,high aluminium ceramic proppants

Discuss the firing temperature, particle size of raw material, additive and the addition of BaCO3 ceramic proppant acid resistance, crush resistance effect.

  The results show that, the development of samples in laboratory, the acid solubility as low as 0.75%, 86MPa < 2.5% broken rate. The addition of BaCO3 could significantly increase the acid resistance of ceramic proppant, as long as good control of the adding amount, significantly improve the crushing rate and can not cause.

Proppant transfer new technology application


PropelSSP technology can prevent the proppant in low viscosity liquids of settlement.

  PropelSSP polymer conveying system can complete gum breaking, prevent the proppant filling and formation damage.

  PropelSSP can recover 100% of conductivity, and guar gum base fluid due to the relatively clean fracturing fluid of the poor, the flow capacity recovery rate is only about 70%.

  Viscous supporting agent through the low viscosity fluid delivery reduces fluid sweep area.

  Transfer capability of PropelSSP is better than slippery water, which can reduce the pumping time. The volume of fluid required is also reduced, and the additives are needed to reduce the response.

Application of ceramic proppant

In the oil and gas development process, inject the right amount of fracturing support agent not only can improve the permeability of reservoir, but also can increase oil and gas production, improving the development benefit of oil and gas wells.
After the oil fracturing support agent making the injection pump stops, the bottom hole pressure reduction in to more than the closed pressure small, let the oil gas well bore cracks always keep open, along with the development of hydraulic fracturing technology, also produced tremendous change proppant synthetic materials.At present  support agent application is mainly ceramic proppant.

In the practice of fracturing proppant

Fracturing proppant is ceramic particle products with high fracturing strength,Which mainly used for oil field downhole support, to increase oil and gas production,and belongs to environmental protection product. This product uses the high quality bauxite and other raw materials, ceramic sintering, is a natural quartz sand, glass ball, a metal ball low strength proppant alternatives, has good effect on increasing production of oil and natural gas.

 Petroleum and natural gas in deep mining, low permeable deposits by fracturing treatment to the high closure pressure, make the rock cracking of oil and gas, oil and gas from the formation of cracks in the channel and out together. With ceramsite propping materials along with high pressure solution into the formation of filling in the rock cranny, to support the cracks due to stress release and closed role, thereby maintaining the high flow capacity, so that oil and gas flow, increase production.

  The practice proved that, the use of ceramic proppant fracturing wells can increase the yield of 3050%, prolong the service life of oil and gas wells.
