摘要:
根据岩心描述、薄片观察及测井解释等资料,对渤海湾盆地歧口凹陷西南缘沙一下亚段碳酸盐岩储集层岩石学特征和沉积微相类型进行研究,认为研究区主要岩性包括生物碎屑灰岩、鲕粒灰岩、泥晶灰岩、泥晶白云岩、白云质灰岩及灰质白云岩,并将碳酸盐岩沉积微相划分为颗粒滩、云灰湾和云质洼地。通过不同岩性测井响应特征的分析,总结出各种类型碳酸盐岩的测井曲线数值特征,建立了研究区碳酸盐岩测井识别图版。在沉积微相特征分析的基础上,结合沉积背景,分别建立了研究区西部斜坡区和东部断阶带的沉积相模式:西部斜坡区凸起周围缺少陆源碎屑物质的注入,高能环境的颗粒滩和低能环境的云灰湾及云质洼地并存,而东部断阶带凸起周围有陆源碎屑的注入,只发育低能环境的云灰湾和云质洼地。研究区沉积模式的建立,为渤海湾盆地类似地区的碳酸盐岩油气储集层预测,提供了可借鉴的地质模型。
Abstract:
The petrophysical characteristics and sedimentary microfacies type of the lacustrine carbonate rocks in the lower Sha?1memberof Shahejie formation in the southwestern margin of Qikou sag are classified by means of core description, thin section observation and well logging interpretation. The lithology in this study area includes bioclastic limestone, oolitic limestone, micrite, micritic dolomite, dolomitic limestone and lime dolomite. The sedimentary microfacies of carbonate rocks are classified as particle beach, dolomitic limestone lake?bay and dolomitic bottom land. Through the analysis of different lithology logging response characteristics, the logging curve numerical characteristics of various types of carbonate rocks are summed up, and the logging identification chart for such carbonate rocks in this area. Also, the sedimentary facies models for the western slope area and the eastern step?fault zone in this area are established, respectively on the basis of analysis of the microfacies characteristics and sedimentary setting. This paper suggests that the areas surrounding the western slope swells lack of charge of terrigenous clastic materials, which allow the particle beach in high energy environment and the dolomitic limestone lake?bay and dolomitic bottom land in low energy environment to coexist, while in the areas surrounding the eastern step?fault zone swell there exist charges of terigenous clasitc materials, but only develop the lake?bay and bottom land. The sedimentary models are helpful to the carbonate reservoir prediction in the similar areas in Bohai Bay basin
