定向钻井技术是复杂断块油田经济高效开发的主导钻井技术和有效途径,精细油藏描述和准确的剩余油分布是定向井取得高效的关键,认识到位、措施得力是定向井获得高效的重要环节。该项技术对提高文留油田勘探开发效益发挥了独特的作用。文中就定向钻井技术在文留油田勘探开发中的应用,按地质目的进行了分类概述,并根据几年的实践结果对应用效果和经济效益进行了评价。

The directional drilling is a main and advanced drilling technology to develop the complicated fault block oil fields economically and effectivly. It’s based on the precise oil reservoir description and remaining oil distribution , and the clear reservoir recognition and effective application are important steps in directional drilling. This article present s the application of the technology according to different geologic target s and evaluates the effect and benefit with practical experience. This technology has played special roles in increasing the benefit of Wenliu Oil Field exploration and development.
