【摘要】：LG油田开发的主要目的层为葡萄花油层。但由于该区油水分布复杂,油水同层十分发育(油水同层地质储量占总储量的67%;统计区内探评井试油资料,油水同层占试油总层数的53%),油水层识别难度大,从而影响了射孔方案的编制和储量的有效有序动用,为此,本文开展了对LG油田复杂油水识别方法研究,为油田产能建设提供技术支持。本文通过测井、录井、取心、试油等资料,采用趋势分析法对测井曲线进行标准化研究,通过校正后的AC、GR曲线交会图,确定曲线的合理性,从而建立储层“四性关系”,并在“分区、分段、分类”的基础上,研究不同类型储层的流体识别方法,分区分类建立油水层解释模型。通过岩电实验,选取适合不同孔隙类型的油水解释评价参数,分区研究含水饱和度计算方法,建立产水率计算模型,在此基础上,建立定性与定量相结合的油水同层细分模型,还通过分析低阻油层、高阻水层成因,建立低阻油层和高阻水层识别方法。本论文通过对全区已有的岩心物性分析化验数据、重矿物含量及组合关系、粘土矿物绝对含量及相对含量、粒度分析、压汞毛管压力等多项实测资料的组合和统计,结合已有的沉积相、构造特征,开展LG油田油水层解释方法的研究,建立精细的地质模型,分区、分类建立油水层解释图版和含水率解释模型,为LG油田的大面积开发奠定一定的基础。
[Abstract]:The main purpose of LG oilfield development in Putaohua formation. But because of the oil-water distribution in this area is very complex, oil-water layer development (oil-water layer geological reserves accounted for 67% of total reserves; statistical area exploration appraisal wells oil test data, test oil and oil-water layer accounted for total number of 53%), the identification difficult large, thus affecting the preparation and reserves perforation design effective and orderly use, therefore, this paper carried on the research of LG oilfield oil identification methods, and provide technical support for oilfield productivity construction. Through well logging, logging, coring, oil testing data, standardization of logging curve by using the trend analysis method. The corrected AC, GR curve intersection diagram, determine the rationality of the curve, so as to establish reservoir "four properties" and "segment in the partition, based on the classification of fluid identification methods of different types of reservoirs, the establishment of oil layer classification To explain the model. Through the rock electric experiment, selecting the suitable water and different pore types interpretation parameters, calculation method of zoning of water saturation, water production rate calculation model is established, based on the model of water to establish qualitative and quantitative with layers, through the analysis of low resistivity reservoir, high resistivity water causes a low resistivity and high resistivity water layer identification method. This paper through the core properties of the existing test data, heavy mineral content and association, granularity analysis of clay mineral content and relative content of mercury, such as hair tube pressure measured data combination and statistics, combining the sedimentary facies, tectonic features. To carry out the Study on the interpretation method of LG oil and water layer, the establishment of a geological model, fine partition, classification established oil layer interpretation chart and moisture interpretation model for LG oilfield development lay a large area The foundation.
