摘要
针对杏北地区断层分布比较复杂及油层非均质性比较严重的特点 ,阐述了在杏 4～ 6面积开发区聚驱布井方案编制过程中 ,用构造描述成果预测是否断失目的层 ,合理移动布井井位 ,解决了断层附近布井断失目的层的难题。用储层精细描述成果不仅考虑地面因素 ,而且深入到油层 ,考虑层与层之间的连通关系及油层纵向的发育状况 ,确定合理的布井井位 ,增加目的油层可钻遇厚度 ,使油层的动用程度和单砂体的完善程度得到进一步提高。在杏 4～ 6面积聚驱布井方案的编制过程中 ,优化移动布井井位 34口 ,平均单井增加有效厚度 3 5m 。
Facing the problem of the complicated fault distribution and reservoir heterogeneity in Xingbei area, this paper introduces the method which uses structural description result to shift reasonably well sites and solve the problem that the object horizon loses around the fault. It involves not only the surface factors, but also the communication among reservoirs and the vertical development of the reservoir. It determines reasonable well sites and increases the penetrated thickniss of the object reservoir so as to improve the reservoir producing and single sand body perfecting.
