Ceramsite Petroleum Fracturing Proppant For Oil Field Mining Machine Spare Parts

1. Introduction of proppant products for oil field fracturing mining machine spare parts

At present, the commonly used proppants mainly include quartz sand, aluminum-vanadium clay sand and resin coated composite particles. Quartz sand is widely used because of its low cost, low density and easy to pump, but it is not suitable for deep Wells with high closure pressure because of its strong bottom and poor sphericity, which reduces fracture conductivity. Resin coated compound particles of quartz sand, sphericity is improved and corrosion resistance is strong, diverting capacity is better also, retention period is short, but the product cost is too high, the cost of today's promotion is not easy, and adopts aluminium vanadium and soil in the process of ceramsite ceramsite proppant, high density, good sphericity, corrosion resistance, high temperature resistance, resistance to high pressure, the cost at the same time be able to get good control, Therefore, more and more widely used by oil and gas fields. Practice has proved that the use of ceramsite proppant fracturing oil Wells can increase production by 30-50%, but also prolong the service life of oil and gas Wells. It is a key material for the exploitation and construction of low permeability oil and gas Wells, which can not only increase oil and gas production, but also prolong the service life of oil and gas Wells.

2. Performance requirements of petroleum proppant mining machine spare parts:

(1) The proppant must have sufficient compressive strength and wear resistance to withstand strong pressure and friction during injection and effectively support artificial fractures.

(2) The relative density of proppant particles should be low to facilitate pumping downhole.

(3) Proppant particles do not chemically interact with fracturing fluids and reservoir fluids at a temperature of 200 degrees, and the maximum allowable acid solubility should be less than 7%.

3. Proppant product parameters for petroleum fracturing mining machine spare parts

The petroleum fracturing proppant produced by our factory has high fracturing intensity and is mainly used for downhole support of oil field to increase the output of oil and gas. It is an environmental protection product. This product makes use of high-quality bauxite and other raw materials, sintered with ceramic, natural quartz sand, glass ball, metal ball and other medium and low strength proppant substitute, has a good effect on increasing oil and gas production. In the exploitation of deep oil and gas Wells, the high closed pressure and low permeability ore deposits are fractured and the oil and gas come out from the channels formed by the fractures. The ceramsite support material along with the high-pressure solution is used to enter the formation and fill in the rock fissures, which plays a role of supporting the fissures without closure due to stress release, so as to maintain high conductivity, make oil and gas smooth and increase production. It has been proven that Wells fractured with ceramic proppants can increase production by 30-50% and extend well life. Proppants can be widely used in deep Wells and high-pressure oil and gas reservoirs. High quality bauxite as the main raw material by crushing fine grinding into powder, with a variety of additives, repeated mixing, granulation, polishing. Sintered at high temperature, the product has the advantages of high compressive strength, low density, good sphericity, high finish, strong conductivity and so on. According to the test of support evaluation Laboratory of Langfang Branch of PETROCHINA Research Institute of Petroleum Exploration and Development, all performance indexes fully meet the standards of SY/T5108-2006 and SY/T6302-1997, which are in the leading level at present.

(1) According to the crushing resistance of 52MPa(7500psi), 69MPa(10000psi) and 86MPa(12500psi), 102MPa(15000psi) four series.

(2) According to the volume density, it can be divided into low density, medium density and high density.

(3) According to specifications :12-20 mesh, 16-20 mesh, 16-30 mesh, 20-40 mesh, 30-50 mesh, 40-60 mesh, 40-70 mesh, 70-100 mesh, etc.

In order to meet the needs of domestic and foreign oil and gas Wells, users can choose different strength and different specifications of products according to the depth of the oil well.
