断块油气藏产生于断层切割剧烈的构造上,以多含油层系、多油水系统为特征。在油田开发前期,稳产主要通过接替(层间、井间、断块间) 实现,开发部署时要做到以下几点:井网应具有较高的控制程度和较强的灵活性;层系划分应有利于层间接替;在合理利用地层能量的同时,及时注水为稳产创造条件。完善井网、钻定向井、综合治理是此类型油田开发后期挖潜的重要手段,重点是以落实断层精确位置、研究断裂组合与断块划分为主要内容的精细油藏描述。

Formed in the structure of which the cutting caused by faults is strong , the fault - block reservoir’s character is more oil - beaing and oil – water system. In the earlier stage of oilfield development , the stablization of oil production was realized by replacement of production , including interlayers ,interwells and among fault blocks. The following aspects must be done when the oilfield development project will be disposed : (1) high control degree and strong flexibility of well pattern ; (2) layer series division is much beneficial to interlayer replacement ;(3) while using formation energy reasonably ,water will be injected in time to insure the stabilization of oil production. The important method of potential digging of the oilfield at later stage are perfecting well patterns ,drilling directional wells and comprehensive treatment.
