中文摘要:达14断块区为典型的多层状砂岩储层类断块油藏,含油层系有二套,分别为下白垩系腾格尔组上段和都红木组一段,仅注水开发5年多就进入高含水开发中晚期阶段,随着“三大”开发矛盾的显现,其开发效果和效益变差。针对该区断裂构造发育、储层分布相对较稳定的特点,对该区开展了微构造地质特征研究,以三维地震精细构造解释为主要技术,编制含油层系顶界面微构造图,结合测井小层精细对比落实微断层、微新断块圈闭等,并结合开发动态分析微构造对断块油藏的开发影响,指导制定剩余油挖潜措施对策,为改善达14断块区高含水阶段开发效果提供了有力的技术保障。

Study on microstructure characteristics of fault block DA14 and it’s influence on reservoir development
Abstract:Fault Block DA14 is a typical multilayered sandstone fault block reservoir which two series of players: Tenggeer Group and first member of Duhongmu Group. It has become into Middle and late stage of high water-cut development only after five years of waterflood development. The development effect and benefit become worse. In view of the characteristics of relatively stable reservoir distribution but fault development in this area, a study on the micro-structure was carried out. Based on the 3d seismic fine structure interpretation technique, the microstructure map of oil-bearing strata was compiled, the micro-fault and micro- traps were confirmed by logging comparison. Combined with the dynamic analysis to estimate the impact of microstructure on the development of fault block reservoir. And then to formulate the policy to develop the residual oil, which will provides a strong technical guarantee for improving the development effect of high-water-cut stage in the fault block Da14.
