针对辽河油区小洼—海外河油田储、盖层及其测井响应特点 ,若孤立地对储层进行评价解释 ,则出现较多难以解决的问题 ,据此 ,利用灰色系统理论对该区储盖组合进行测井解释研究。目的 为该区油气勘探和开发提供可靠的地质依据。结果 通过对该区 2 0多口井主要含油目的层段岩性、物性、含油性及盖层质量的评价和分析 ,建立了精细评价储、盖层的参数、标准及权系数 ,经应用获得了较满意的效果。其主要储盖组合测井解释与相应的试油情况相吻合 ,评价解释符合率达 90 %。结论 利用灰色系统理论在该区进行储盖组合测井解释 ,对区内不同质量盖层及其储盖组合特点有了新的认识 ,且能有效地分析该地区油气藏及其分布。
According to the characteristics of reservoir and cap rock and logging response in Xiaowa-Haihehe oilfield in Liaohe Oilfield, if the reservoirs are evaluated and explained in isolation, there are many problems that are difficult to be solved. Based on the above, Reservoir-cap combination logging interpretation study. The purpose is to provide a reliable geological basis for oil and gas exploration and development in this area. Results Through the evaluation and analysis of lithology, physical property, oil content and cover quality of the main oil-bearing formation in more than 20 wells in this area, the parameters, standards and weight coefficients for fine evaluation of reservoirs and caprocks were established. After application, A more satisfactory results. Its main reservoir combination logging interpretation and the corresponding test oil match, the evaluation explained that the rate of 90%. Conclusion Based on the gray system theory, reservoir-cap combination log interpretation is carried out in this area, and new understanding of the characteristics of different quality caprocks and their reservoir-cap assemblages in the area is obtained, and the oil and gas reservoirs and their distribution in this area can be effectively analyzed.
