摘要
低渗油藏水平井开发是一项复杂而又有实际价值的工程技术。如何能更有效地利用水平井压裂化学配套技术来提高压裂效果,面临着诸多难题。如污染、支撑剂沉降速度控制、返排困难等。文章从水平井压裂的储层保护、压裂液的携砂性能以及分段破胶快速返排及强制闭合压裂配套技术方面进行了探讨,为改善水平井开发低渗透油田效果提供了技术支撑。
The fracturing operation used in development of low permeability reservoir with the horizontal well has many technical challenges,such as reservoir pollution,control of proppant setting velocity and effective flow back of fracture fluid.The fracturing supporting technologies on reservoir protection in horizontal well fracturing operation,solid-carrying behavior of fracture fluid,rapid flow back of fracture fluid and forced closing of fracture and so on were researched.The application of this novel fracturing technology will improve the development effect of low permeability reservoir.
