江苏老区油田滚动开发的关键技术和措施

江苏老区油田分布在苏北盆地东台坳陷的高邮、金湖、海安凹陷及吴堡低凸起上 ,均为复杂小断块油田。老区滚动开发的关键在于提高圈闭的落实程、搞清砂体的展布及油气聚集的深化研究等 ,并且要把三维地震构造精细解释、钻后反馈、油藏深化评价贯穿于老区油田滚动开发的全过程。多学科综合研究采用的关键技术有 :三维地震技术、测井分析技术、构造研究技术、储集层研究技术、断层封闭性研究技术、动态分析及油藏数值模拟技术。以宋家垛、黄珏油田为例 ,具体运用了全三维处理解释技术、SEIMPAR多信息反演技术 ,发现了 3个含油断块 (宋家垛油田 )、增加探明储量 4 2 2 .3× 1 0 4t(黄珏油田 )的显著成果。图3参 1

Some key technical measures used in progressively developing old fields of Jiangsu

The old oil fields of Jiangsu developed are located at Gaoyou, Jinhu, Haian sags and Wubao arch of Dongtan depression, Subei basin. These oil fields are composed of fault block reservoirs. The key to progressively develop these oil fields is making trap sure and getting a clear understanding of the distribution of reservoir. By using multi subject theory and applying integrative progress development technology, the authors systemically summarized workflows and key technical measures of progress development in old oilfields. The great achievement such as new oil block and increasing reserve have been gotten through the application of full 3D processing and interpretation technology and multi parameter inversion of seismic technology (SEIMPAR) in Songjiaduo and Huangjue oil fields.
