Aplication and Research of the Numerical Simulation of Sand Control by Fracturing

论述了疏松砂岩油藏压裂防砂机理及关键理论技术,进行了数值模拟研究,并以Mfrac、Gohfer、Fracpro软件为例,进行了裂缝形状及参数预测、压后效果分析、射孔层段/排量/液量优化组合、加转向剂缝高控制模拟等,数模结果在众多区块、油井的现场应用中取得了良好效果,为该类油藏防砂和高效开发提供了借鉴。

This paper discussed the mechanism, key theory and technique of sand control and studied on the correlative numerical simulations.In addition,we forecasted the fracture shape and parameters and the fracturing effects taking the software simulation such as Mfrac ,Gohfer and Fracpro as an example.The swept volume and liquid volume are optimized and fracture height control added with diverter is simulated with a good effect in the field application at many wells and blocks of the oilfield,which can provide the sand control and the efficient exploitation of such reservoirs with a good reference.
