本文以塔北哈得逊油田超深水平井井轨迹为研究对象,提出了海相层状油藏超深水平井轨迹校正技术.该技术应用顶面识别、井震结合、三维校正的方法,实现了目的层东河砂岩段水平井轨迹的精细深度校正,方法实用、可靠,对水平井的开发地质研究及注采方案的精细调整起到了重要作用.该技术已被塔里木哈得逊油田研究人员所普遍认可并得到应用,为解决塔里木及其他地区超深水平井轨迹问题提供了一种可靠有效的校正方法和思路.
In this paper, the ultra-deep horizontal well trajectory in the Hudson oilfield of Tarim Basin is taken as the research object, and the ultra-deep horizontal well trajectory correction technique in the marine stratified reservoir is proposed.This method uses the method of top recognition, wellbore combination and three-dimensional correction The fine depth correction of the horizontal well trajectory in the Donghe sandstone section of the target layer is practical and reliable and plays an important role in the development of the horizontal well and the fine adjustment of the injection and production plan.The technology has been used by researchers in the Haredon field in Tarim It is generally accepted and applied that it provides a reliable and effective method and idea for solving the problem of ultra-deep horizontal well trajectories in Tarim and other areas.
