红河油田水平井分段压裂技术研究

红河油田存在物性差,注水困难等问题,水平井分段压裂已成为其主导开发技术.本文对红河油田压裂液和支撑剂进行优选,并在裂缝和施工参数优化的基础上,现场应用了四种压裂工艺.实践表明,现用的裸眼封隔器压裂工艺效果较好,但不利于后期改造,而套管固井速钻桥塞压裂工艺避免了这一缺点,可大规模推广应用.下步可继续引进新的压裂工艺,为红河油田下一步深入开发和储层改造工艺进一步优化提供技术支撑.

Research of Horizontal Well Staged Fracturing Technology in Honghe Oilfield

To solve the problem of poor reservoir property and difficult water injection in Honghe Oilfield, horizontal ~ell staged fracturing technology has become the main exploitation method. Fracturing fluid and proppant was opti- mized and 4 fracturing technology were used in Honghe Oilfield on the basis of fracture and design parameter opti- mization. Field application indicates that the effect of multistage external packer fracturing technology is good how- ever its later reformation is difficult. Casing cementing drillable bridge plug fracturing technology avoid the problem and could be used in large - scale applications. New technology could be bringed in to provide technical support for the optimizing of next reservoir fracturing technology.
