靖安油田盘古梁区长6油藏高效开发配套技术研究

Auxiliary Techniques of High Efficient Development of the Reservoir Chang6 in Panguliang Area of Jing'an Oilfield

靖安油田盘古梁区长6油藏属典型特低渗透油藏,具有低渗透油藏开发的一切特征,但同时又有别于其他低渗透油藏的开发。主要从油藏动态分析、数值模拟和油藏工程等多方面着手研究制定了分区域、分时步变注采比的开发技术政策,开展了以水动力受效单元为核心的平面、剖面综合调控技术和低产井治理等一系列针对性强、适应性好的配套开发技术,结果表明研究区通过合理的开发技术政策以及配套技术,油藏两项递减逐年降低、地层能量稳步回升,井组水驱指数和存水率不断上升,油藏实现了高效开发。

Reservoir Chang-6 in Panguliang Area of Jing'an Oilfield was a typical extra-low permeability reservoir with all the features of development of low permeability reservoirs,but simultaneously it was different from other low-permeability reservoir development.Starting from reservoir performance analysis,numerical simulation ,reservoir engineering and other aspects,the development technical policy of zoning,time-stepping changing injection-production ratio were established,the hydrodynamic affected unit used as the kernel of study,including the plane and section integrated controlling technologies were carried out,in combination with targeted and flexible matching exploration technologies.The research results show that technique is practical for increasing in-situ energy and improving waterflooding coefficient and water storage rate and for efficient oil reservoir development.
