砂岩岩性油藏是一种重要的隐蔽油气藏,勘探的主要问题是储层识别和描述问题。砂岩储集体的识别和描述则需要地质、地震和测井的紧密结合。针对济阳坳陷陡坡带复杂砂岩储集体的地震地质特点及勘探中存在的主要难点,在地质研究的基础上,采用测井约束反演、三维可视化、多属性体联合解释等技术,对储集体进行了综合解释。加强了技术适用性研究,形成了适应砂砾岩扇体的综合解释配套技术。该套技术在盐家、罗家等地区的应用收到了很好的效果。

Sand reservoir is one kind of important subtle reservoir. The key to exploring such reservoirs is reservoir recognition and characterization, which can be achieved by jointly using geologic, seismic, and well logging data. For the complex sand reservoirs at the steep slope belt of Jiyang depression, this paper proposed to carry out integrated interpretation for reservoirs by logging constrained inversion, 3-D visualization, and joint interpretation of different attribute sets. A suite of methods has been developed. Desired results have been achieved by applying these methods in areas such as Yanjia and Luojia.
