Research On Preparation Of Low Density And High Strength Hydraulic Fracturing Proppant

The scientific and technological revolution and concept change of the oil industry caused by the "shale gas revolution" in North America have made the production and supply of the global natural gas greatly increased.The oil and gas reservoirs that have been considered to have no mining value have now been considered to have huge industrial recoverable reserves and commercial value,making the global oil and gas industry being from the world Conventional oil and gas exploration and development are moving towards exploration and development of unconventional oil and gas.Based on the in-depth analysis of the development history,classification and influencing factors of the current hydraulic fracturing proppant,this paper makes a kind of low density and high strength hydraulic fracturing proppant by adding a certain proportion of toughening agent and polyepoxide.Secondly,according to the SY/T 5108-2014 standard,the test material is tested in detail.One of the most concerned elements of the test data is that the volume density is only 0.54 kg/m3.This index will surpass the prevailing proppant in the market and will greatly reduce the performance requirements of the fluid carrying fluid during the hydraulic fracturing process,and further reduce the energy consumption cost of the construction pump;the hardness of the material is completely in conformity with the unconventional energy exploitation.Geological environment,which can support and form cracks with high conductivity.The chemical properties of the samples are stable and can withstand the corrosion of hydrofluoric acid mixed solution in the actual fracturing process;the size of the sample is more uniform and more uniform and more distributed.Artificial fractures with uniform porosity,large porosity and high permeability.The test results show that the test material has good product performance.
