八面河油田面120区低渗透稠油油藏开发对策

Development strategy of low permeability heavy oil reservoirs in Mian 120 Area of Bamianhe Oilfield

八面河油田面120区属于中-低渗透非均质稠油油藏,由于油稠、地层出砂、地层压力低、产能低等问题,开发效果不理想,一直未投入全面开发。为了提高面120区原油储量动用程度,提高开发效益,从2001年起对该区开展了低渗透非均质稠油油藏改善开发效果技术研究。通过数值模拟优化、热力开采设计及相应的采油工艺配套设计,确定了合理开发对策,取得了较好开发效果。

Mian 120 Area of Bamianhe Oilfield belongs to middle-low permeability heterogeneous heavy oil reservoirs. For the problems of heavy oil,formation sand flow,low pressure and low productivity,the development effect is not good,and is not put into exploitation entirely. Research on improving exploitation effect of low permeability heterogeneous heavy oil reservoirs has being developed since the year of 2001 so as to enhance the reserves utility and development benefit. Through optimization of numerical simulation,thermal recovery design and corresponding oil recovery technology,the reasonable development policy is determined and some good results have been gained.
