【摘要】：基于岩心描述、地化分析及相关测井曲线孔渗的实验数据,研究了大安油田扶余油层的孔渗发育特征、储层含油性的主控因素有哪些等问题,通过划分含油性级别和对其分级识别后进行分类,以此达到储层含油性评价的目的。大安油田位于松辽盆地南部中央坳陷区大安红岗阶地的二级构造带中,研究区内主要发育河控三角洲沉积体系,地层变化相对复杂,存在超低渗致密砂岩储层。本文结合宏观沉积特征与微观储层结构特征,利用实验手段结合生产相关数据,得出研究区内分流河道微相主要以含油、油浸和油斑为主,河口坝微相为油斑、荧光和不含油,席状砂微相为油斑和不含油,天然堤微相都不含油,道间薄层砂微相为油斑、荧光和不含油。根据相关数据,建立了含油性与测井关系划分模版,为大安油田扶余油层后续研究提供参考。
[Abstract]:Based on core description, geochemistry analysis and experimental data of porosity and permeability of logging curve, the characteristics of pore and permeability development of Fuyu reservoir in Da'an oilfield and the main controlling factors of reservoir oil content are studied. In order to achieve the purpose of reservoir oil-bearing evaluation, the oil bearing grade is classified and classified after classification. The Da'an oilfield is located in the secondary structural zone of the Da'an Honggang terrace in the central depression of the southern Songliao Basin. The fluvial delta sedimentary system is mainly developed in the study area, the stratigraphic changes are relatively complex, and there is an ultra-low permeability tight sandstone reservoir. In this paper, combining the macroscopic sedimentary characteristics with the microscopic reservoir structure characteristics, we combine the experimental means with the production data. It is concluded that the microfacies of distributary channel in the study area are mainly oil bearing, oil immersion and oil spots, oil spots in estuaries and dams, oil spots and no oil in sheet sand microfacies, no oil in natural embankment microfacies, and oil spots in thin sand microfacies in interchannel. Based on the relevant data, the relationship between oil bearing and logging is established, which provides a reference for the further study of Fuyu reservoir in Da'an Oilfield.
