摘要(Abstract)：

复杂断块油藏是大庆油田稳产的重要接替领域,多年来针对复杂断块油藏地质特点,基于古地貌恢复重构盆地原型模型,刻画了断裂系统和主力砂体展布等精细油藏描述,深化了成藏模式类型与复杂油水分布规律认识。系统开展了井网优化、滚动外扩,形成了多轮次滚动高效开发模式,有效支撑了塔木察格油田上产到100×10~4 t产量规模,主力断块采油速度保持在1.2%以上,取得了较好的开发效果,对类似的合作开发区块具有指导意义。
Complex fault-block oil reservoir is an important replacing field for the stable production of Daqing Oilfield. In the light of the geological characteristics of the reservoir for many years, the basin prototype model was reconstructed based on the palaeogeomorphological restoration, the fine reservoir descriptions such as the fracture system and main sandbody distribution were depicted, the understandings of the reservoir-accumulating model type and complex oil-water distribution law were deepened. Well pattern optimization and progressive expansion were carried out systematically, thus the multi-round progressive and high-efficiency developing model have been established, and the effective support was presented for the production scale of Tamutsag Oilfield up to 1 million tons, the oil production rate of the main fault block is maintained above 1.2%, so much better developed effects have been achieved, and furthermore these achievements possess a certain guiding significances for the development of similar cooperative blocks.
