致密储层压裂设计优化

目前国内致密油储层大规模压裂总体效果较好,但经济性差,无法满足效益开发.储层非均质性强,物性、含油性差异大,部分层段投入与产出不成比例,若压裂设计时只考虑井周储层情况,结果也满足不了当前需求.通过地质工程一体化理论研究,形成适度规模多方案经济优化技术,解决致密油施工规模与储层适应性难题,降低施工成本,实现储层经济有效动...

Optimization of Fracturing Design for Tight Oil Reservoir

At present,the overall effect of large-scale fracturing for tight oil reservoirs is good,but the economy is poor,which cannot meet the benefit development.The reservoir heterogeneity is strong,the physical and oil bearing properties differ greatly,and the input and output of some intervals are out of proportion.If only considering the reservoir around a well in the fracturing design,the result cannot meet the current demand.Through the theoretical research of geological engineering integration,the economic optimization technology of moderate scale and multi scheme is formed to solve the problem of tight oil construction scale and reservoir adaptability.Finally,the construction cost is reduced,the economic and effective use of reservoir is realized.
