摘要
水平井完井技术是整个水平井开发中的重要组成部分,直接影响油田开发调整和最终采收率的提高。从水平井完井方式在盐湖地层应用应考虑的因素入手,重点探讨水平井段在江汉盐湖地层的受力状况,研究认为:水平井段主要受泥岩水化导致井壁坍塌、盐岩蠕变导致的井壁变形、垂向应力波动导致井壁破裂三个方面的影响。结合油区实际,指出单纯的裸眼完井方式不适合于江汉盐湖地层,同时提出有针对性的完井方式,其研究成果对水平井在江汉油区的高效开发具有重要的指导价值。
As an important part of horizontal well development, horizontal well completion technology has a direct influence in oilfield development adjustment and improvement of recovery ratio. Starting from the factors to be considered of the application of horizontal well completion method in saline formation, this paper discusses mainly the stress state of net horizontal section in Jianghan saline formation and concludes that the horizontal section is influenced by three factors that hydration of mudstone leads to hole-wall collapsing, creep of rock salt leads to hole- wall deformation and vertical stress fluctuation leads to hole-wall fracture, followed by the presentation of well- targeted horizontal well completion method contributing to high-efficient development of Jianghan oil region.
