本文从分析断块圈闭形成的石油地质条件、断层封闭性条件入手，综合应用模糊评判和计算机等先进技术，开发了一套适合断块圈闭评价的综合评判技术──多级模糊综合评判技术。应用该技术对柳堡地区的八个断块圈闭进行了评价，成功地预测了高产区和非产区。该项技术既可单独对储层、断层封闭性进行评价，又可对断块圈闭的含油性进行综合评价。 Based on the analysis of the petroleum geological conditions and fault sealing conditions formed by fault block traps, this paper developed a set of comprehensive evaluation techniques suitable for the evaluation of block traps based on fuzzy evaluation and computer-based multi-level fuzzy comprehensive evaluation technology. Applying this technique, eight fault block traps in Liubo area were evaluated, and the high-yielding and non-producing areas were successfully predicted. The technology can not only evaluate reservoirs and fault seals separately, but also evaluate the oil content of fault block traps comprehensively.
