摘要
水平井裸眼分段压裂完井是改变低渗透油气田多井低产、转变发展方式、实现少井高产的重要手段。新疆油田部署了一组评价水平井,采用了水平井裸眼分段压裂完井技术进行储藏改造。现场实践证明,合理应用水平井裸眼分段压裂完井技术开发低渗储层,能提高储层动用程度,实现经济高效开发。文中介绍了水平井裸眼分段压裂完井管柱的结构、工作原理、技术特点以及配套工具的结构特征,并以夏721_H井为例,阐述了水平井裸眼分段完井的工艺流程及现场应用情况。
Staged fracturing in horizontal open-hole wells is an important method to reverse low Production rate in low permeability reservoir,change development method,and achieve high production rate. Xinjiang Oilfield deployed a set of evaluation of horizontal wells,using this technology for storage transformation. The field practice proves that the proper application of staged fracturing in horizontal open-hole wells technology to develop low permeability reservoirs can improve the reservoir producing level, achieve economical and high-efficiency development. This paper introduced the structure,working principles,technical characteristics of completion string and its associated equipment structure. Using Well Xia 721_H as an example,staged fracturing procedure and the field application was introduced.
