Support the artificial fracture of proppant

Is the purpose of the hydraulic fracturing with frac sand companiesin formation formed a support of the artificial fracture, high to low permeability reservoir capacity. Proppant, and in the process of fracturing pump injection into the formation, due to the fracturing liquid carrying, reservoir water and the existence of condensate water, led to the fracturing proppant has been in the process of the production and formation water in the process of soaking, according to the conventional experimental methods selection under the condition of proppant can meet the needs of the actual reservoir percolation relations become reservoir optimization designers need to consider the problem. In this paper the present fracturing acidizing fracture diverting capacity test and analysis system, for the first time in a simulated formation water environment of formation water after soaking frac sand crushing rate, compares the flow conductivity performance evaluation experiment, for proppant fracturing stimulation in more optimal selection provides certain reference basis. A, experimental apparatus and principle 1. The experimental apparatus in haian oil machinery factory production of fracturing acidizing fracture diverting capacity test and analysis system, the instrument can simulate the formation temperature and pressure, training room, in accordance with API standard design, proppant crushing rate experiment used broken reference oil formulated the industry standard SY/T5108-2006.
