摘要
W30B组油藏为构造岩性控制的边水油藏,井网加密后采用五点法注水开发,投产压裂的主要目的为解除近井地带污染问题。在充分认识该油藏地质特征情况下,分析各种压裂工艺适应性并精准优化施工参数,形成了一整套精准压裂改造工艺技术,实现了在有效控制裂缝高度同时,最大限度提高各小层数动用程度等实际需求,提高了该区块的有效动用程度与油藏开发效益。
The W30B reservoir is a structural lithology-controlled edge water reservoir.After the well pattern infilling,five-point water injection method was adopted.The main purpose of the fracturing operation is to remove the pollution problem in the near-wellbore area.Under the condition of fully understanding the geological characteristics of the reservoir,various fracturing process adaptability was analyzed,the construction parameters were precisely optimized,and a set of precision fracturing transformation technology was formed.In addition to effectively controlling the height of fractures,the actual demands such as the operating degree of each small layer are maximized,which improves the effective operating degree and reservoir development benefits of this block.
