腰滩油田阜宁组油藏为复杂断块油藏,目前处于滚动勘探开发期,但油藏含水高、水淹问题突出。针对腰滩油田的水淹问题,从储层的非均质性、注采井网与地应力的适应性、储层伤害及油藏成藏后油水分布特征等方面进行了研究,找到了腰滩油田水驱开发效果不理想的原因所在,并结合研究设计了改善水驱开发效果的技术方案。
The Funing Formation reservoirs in the Wa-Tan Oilfield are complex fault-block reservoirs and are currently in the period of rolling exploration and development. However, the reservoirs have high water content and prominent flooding problems. In view of the flooding problem of the waist beach oilfield, the paper studied the heterogeneity of the reservoir, the adaptability of the injection well and the underground stress, the damage of the reservoir and the distribution of oil and water after the reservoir was formed, and found the waist The reasons for the unsatisfactory development of waterflooding in the Tanushui Oilfield lie in the fact that a combination of research and design of a technical solution to improve the waterflooding development effect has been carried out.
