井间地震技术在油田开发后期的应用
|
摘要
油田开发后期储层预测的重点在于搞清井间的微构造、砂体连通情况、隔夹层的分布及延伸关系。为了搞清楚大庆喇嘛甸油田8-1711井区地下储层的发育状况,在该区采集了4对井的高质量井间地震资料,通过对井间地震资料的提频和反射波成像处理以及地震、地质、测井综合解释和分析,选择了微电极反演作为储层预测的重点。通过井震结合综合解释确定了该井区的井间储集层砂体的横向分布与连通性、隔夹层的分布与大小,为后期的剩余油描述和开发调整提供了有利的依据。
The critical point of reservoir prediction at the late stage of oilfield development was to clarify the micro-structures of interwells,the connectivity of sand bodies and the distribution and extension of interbeds and restraining barriers.For the purpose of clarifying the development status of reservoirs in Wellblock 8-1711 of Daqing Lamadian Oilfield,high-quality interwell seismic data from 4 pairs of wells were collected in the area,a comprehensive interpretation and analysis were performed on earthquakes,geology,logging through picking up high frequency signals and reflected wave imaging technique,micro-electrode inversion technique was chosem as the focus of reservoir prediction.In combination with seismic interpretation method,the horizontal distribution and connectivity of reservoir sand,as well as the distribution and size of interbeds and restraining barriers are all determined in Wellblock 8-1711,which can provide a favorable basis for the description of remaining oil and adjustment of oilfield at the late stage.
