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。
Using well logging technology, the reservoir caprock of the main hydrocarbon-bearing reservoirs in more than 20 wells in a certain area was finely evaluated and matched, fitted and extracted, and the lithology, physical property, oiliness and cap of the reservoir were established Interpretation of layer quality evaluation criteria, weight coefficients and indicators. The lithology fine evaluation is generally consistent with the drilling coring and geological logging data in this area. The reservoir physical properties, oil content and the interpretation and evaluation of cover quality also coincide with the corresponding oil test conclusions. On this basis, this paper analyzes the characteristics and relations of different quality caprocks and their reservoir-cap assemblages in this area, clarifies the distribution rules of the hydrocarbon reservoirs in this area and provides a reliable basis for further exploration and development in this area.
