水平井井眼轨迹发展现状综述

Review of the Development of Horizontal Well Track

随着世界对能源需求的不断增加,各种非常规、复杂的油气资源逐渐成为新的勘探开发领域。这就需要成本低廉,高效先进的水平井技术,而井眼轨迹是制约水平井技术发展的关键。本文分析国内外在水平井井眼轨迹方面的发展现状以及在实际应用中的问题和困难,预测现代水平井钻井技术的发展趋势,在更大程度上加快现代水平井在石油资源开采中的应用。

With the growth of energy demand in the world,a variety of unconventional,complex oil and gas resources gradually become a new field of exploration and development.It requires low cost,high efficiency and advanced horizontal well technology.Well track is the key factor to restrict the development of horizontal well technology.This paper analyzes the present situation of horizontal well track development and the problems and difficulties in the practical application.It also predicts the trend of modern horizontal drilling technology and horizontal wells in the application of modern exploitation of oil resources in a greater extent.
