摘　　要：随着难采难动用储量开发的需要和水平井配套技术的发展完善,利用水平井技术开采薄油层已受到广泛关注,但如何提高薄油层水平井油层钻遇率还是一个难题。为此,辽河油田对此进行了攻关研究,并提出了提高薄油层水平井油层钻遇率的技术措施:在进行水平井地质设计时,首先要弄清构造、沉积相、储层物性、油层的电性特征和油气层显示特征,优化水平井的部署位置,再进行满足地质要求的工程设计;然后在现场实施时,根据定向工具和地质导向工具的测量结果,调整井眼轨迹,实现提高油层钻遇率的目的。以新海27 H7井和洼38东H5井两种不同油藏类型水平井为例,介绍了提高薄油层水平井油层钻遇率技术的应用情况和效果。With the demands of developing difficult-produced-reservoirs and the development of horizontal well drilling technology, horizontal wells have been widely used in thin reservoir. However how to increase the horizontal well drilling footage is still a difficulty problem. Therefore, the corresponding research were conducted in Laihe Oilfield, and the technique measurements were proposed, including identification of structure, deposit, physical properties of reservoir, electrical characteristics of oil zone, optimization of horizontal well location, and the design satisfying the geological requirement. During field implementation, well trajectory was adjusted according to the survey of directional and geosteering tool in order to increase the drilling footage. The application and results of Xinhai 27-H7 well and Wa-38-Dong-H5 Well was introduced as examples for two different type of reservoir.
