利用测井技术, 对某地区20余口井主要含油气目的层段储盖层进行了精细评价及匹配、拟合和提取参数, 并建立了该区储层岩性、物性、含油性及盖层质量评价的解释标准、权系数和指标。岩性精细评价总体上与该区钻井取心及地质录井资料一致, 储层物性、含油性及盖层质量评价解释结果也与相应的试油结论吻合。在此基础上, 着重分析了该区不同质量盖层及其储盖组合特点和关系, 阐明了该区油气层分布规律, 为该区进一步勘探开发提供了可靠的依据。

In an area, fine evaluation, matching, fitting and parameter extraction were performedfor the reservlrs and covdring strata of maln hydIaxben-bearing target layere in more than 2O wells byusing well logging technology. And the interpretation. standard, weight coefficient and index were con-structed for the evaluation of reservolr lithology, physical and oil-bearing property as well as quality ofcovering strata. The evaluation and intopretation results coincided with the drilling core, geologic logand oil testing result. This paper emphatically analyzes the character and relation of covering strata andreservoir combination, and expounds the law of hydrocarbon distribution, which provides reliable basisfor further exploration and development in the area.
