大港油田沈家铺地区的枣Ⅳ、Ⅴ油组属复杂断块稠油油藏 ,由于构造落实程度低、测井解释符合率低、原油性质差、产能不落实 ,一直未能投入开发。 1997年开始 ,在重新处理解释三维地震资料落实构造、测井多井评价、试油、试采的配套采油工艺等方面开展针对性较强的研究及现场实验 ,编制了整体开发方案 ,合理划分开发层系并确定了开发方式及合理采油速率 ,共钻井 3 9口 ,单井产能明显提高 ,形成了较大规模生产能力。图 2表 3参 2 (刘树明摘 )
Jujube Ⅳ and Ⅴ oil reservoirs in Shenjiapu area of Dagang Oilfield belong to the complex fault block heavy oil reservoirs and have not been put into development due to the low degree of tectonic implementation, the low coincidence rate of log interpretation, poor crude oil properties, and insufficient production capacity. Beginning in 1997, we conducted targeted researches and on-site experiments in reprocessing and interpretation of the implementation of 3D seismic data, multi-well logging evaluation, oil testing and the matching oil recovery trial. Developed stratigraphic system and determined the development mode and reasonable oil recovery rate. A total of 39 wells were drilled. The productivity of single well increased significantly, forming a large-scale production capacity. Figure 2 Table 3 reference 2 (Shu-Ming Liu pick)
