大庆西部外围油田滚动开发实践

The Rolling Development Practice of Daqing Peripheral Oilfield

针对大庆西部外围油田地下条件十分复杂的问题 ,叙述了围绕提高钻井成功率 ,降低开发风险所进行的滚动开发的成功实践 ,把 1983— 2 0 0 1年整个滚动开发过程依据不同时期滚动开发目标、实践目标的思路及技术特点分为三个阶段 ,即滚动开发初级阶段 ,滚动开发发展阶段 ,滚动开发提高完善阶段 ,并分阶段阐述了应用地震地质综合预测技术 ,解决不同油田复杂地质情况的具体作法和应用效果。在此基础上 ,概括出滚动开发的研究内容及工作程序 ,即钻前早期评价研究、钻井过程中跟踪预测。

Based on the complexity of the ground and underground condition of Daqing peripheral oilfield, this paper fully depicts the successful practice of rolling development aiming at increasing successful drilling rate and decreasing developing risk. In this paper, the total developing time is divided into three stages according to the rolling development goal, the train of thought being adopting to reach that goal and technique features in different time. It expatiates on the effectiveness of dealing with complex geology condition of different reservoirs. Based on the practice above, it generalizes the contents and working program of rolling development, that's to make an early evaluation and study before drilling, to make the follow up prediction during the course of drilling, and to deepen the understanding of reservoir geology features after drilling. This paper provides instructive importance to the development of the reservoirs with ultra low permeability.
