Abstract

Abstract: Determination of residual oil distribution and accurate selection of reasonable section of horizontal well are the key ways in the developing process of fastigium-faulted reservoir.According to the geological conditions of side-drilling horizontal well,some technologies for researching the geological modeling,residual oil distribution,and sensitivity analysis on geological parameters of horizontal wells were discussed.The optimal direction,length and perforation location of horizontal sections in the side-drilling horizontal wells of the fastigium-faulted reservoir were pointed out.The application of the optimal technique for side-drilling horizontal well in Pan 40 Block of Linpan Oilfield showed the validity of this technique.

Key words: fastigium, faulted reservoir, side-drilling horizontal well, geological modeling, residual oil distribution

摘要： 明确剩余油分布、准确选择合理水平段的位置是开发屋脊式断块油藏的关键.根据屋脊式断块油藏侧钻水平井的地质条件,对地质建模、剩余油分布研究的相关技术进行了综合论述.并研究了水平井地质参数敏感性,指出了这类油藏进行侧钻的水平段最佳优化方位、最佳长度及最佳射开部位.在临盘油田盘40块屋脊式断块油藏应用了侧钻水平井技术,根据剩余油研究结果及优化的水平井地质参数进行了布井.现场实施结果表明,该技术能有效地提高单井产能,证实了研究方法的有效性.
