【摘要】:针对复杂断陷盆地勘探开发面临的诸多难题,加强物探、测井、地质多专业联合攻关,重视室内研究与矿场实际的结合,开展精细油藏描述,明确区块石油地质特征有着十分重要的意义。加快伊通盆地的勘探开发步伐可以缓解吉林油田超低渗透油藏开发效益差的实际现状,是吉林油田持续上产的重要保证。针对区块已知地质及开发特征,对区块物性及测井曲线进行精细分析,油层物性特征分析结果表明Ⅰ、Ⅱ砂组储油层物性、含油性好于Ⅲ、Ⅳ砂组,相同层位断阶内油层物性、含油性要好于断阶外。区块油、水层电性特征复杂。通过流体识别技术标定有效厚度的确定,最终确定有效厚度,计算得伊59区块地质储量1667×104t,其中断阶内地质储量943.0×104t,断阶外地质储量687.6×104t,五砂组地质储量36.0×104t。在系统全面的分析地震构造解释结果的前提下,对区块的构造及断层进行了深入分析,结果表明,双二段各砂组顶面构造特征具有继承性,形态基本一致,断层断距的大小控制着局部构造的幅度高低;平面上研究区内断层分布不均匀,研究区在双阳组发育断层共计140条,其中在西北缘发育两条逆断层,其余均为正断层;对砂组顶面层位边界正断层的空间位置进行了联井刻划的技术,精细层位标定技术、相干体切片技术、逆断层立体显示技术、断层走向成图技术,并结合在有利部位先后部署开发井等技术对策可实现对区块的有效开发。
[Abstract]:In view of the difficulties faced by the exploration and development of complex faulted basins, we should strengthen the combination of geophysical exploration, logging and geology, attach importance to the combination of indoor research and field practice, and carry out fine reservoir description. It is of great significance to clarify the geological characteristics of the block petroleum. Accelerating the pace of exploration and development in Yitong Basin can alleviate the actual situation of poor development efficiency of ultra-low permeability reservoirs in Jilin Oilfield and is an important guarantee for the sustained upproduction of Jilin Oilfield. According to the known geological and development characteristics of the block, the physical properties and logging curves of the block are analyzed in detail. The results show that the physical properties of the reservoir in the 鈪,
