旋转导向钻水平分支井技术在东海油气田的应用

摘要

水平分支井技术在提高低渗透、特低渗透气田开采率发挥了重要的作用，本文分析了水平分支井在东海低渗透油气田的设计原则及使用旋转导向工具侧钻措施，以及水平分支技术在东海油气田的成功应用。%The technology of horizontal branch well plays an important role in improving the exploitation rate of low and extra-low permeable oil-gas fields.This paper analyzes the design principles of horizontal branch well in the low permeable oil-gas fields of East China Sea and the side-drilling measures by using rotary steering tools,and the successful application of horizontal branch technology in east China sea oil-gas fields.
