外围油田的储量区块具有分布零散、地质认识程度低、油藏类型复杂等特点,按照常规的评价、开发模式,短期内这些储量难以动用。如何加快这部分闲置储量评价和经济有效地动用,是外围油田油藏评价、新区产能建设的重要课题。本文在“百井工程”单井开发方案设计中,以评价目的层为重点,充分考虑百井工程评价井多套含油层系、单井构造圈闭、断层展布、主力油层发育方向等特点,采用灵活井网形式和布井方式,按照技术经济最优化原则进行井位部署和开发方案设计,以实现零散区块储量经济有效动用。
The reserves of the peripheral oilfields are characterized by scattered distribution, low level of geological understanding and complex reservoir types. According to the conventional evaluation and development mode, these reserves are difficult to be used in a short period of time. How to expedite the evaluation of this part of idle reserves and the economical and effective utilization is an important issue for reservoir evaluation in peripheral oilfields and capacity building in new districts. In the design of single-well development plan of “One Well”, this paper focuses on the evaluation target layer, and takes full consideration of multiple sets of oil-bearing formations, single-well structural traps, fault distribution and development direction of main oil layers in the well engineering evaluation well And other characteristics, the use of flexible well pattern and well pattern, in accordance with the principle of optimal technical and economic well location deployment and development of program design, in order to achieve the economy and effective use of scattered block reserves.
