摘　　要：随着水平井施工比例的不断增加,浅层油气田的开发力度不断加大,利用水平井技术开发浅层油气田已成为目前行业内普遍采用的方式。但由于油藏埋藏浅,胶结疏松,造斜井段井眼尺寸大,导致该井段内造斜率无法有效控制,通过开展对造斜率理论的研究,在地层自身造斜率一定的前提下,通过改变部分造斜钻具组合的使用参数并调整钻井参数的方式提高该井段内组合的造斜能力,从而达到有效控制井眼轨迹的目的。With the increasing of horizontal drilling operation and the extending of shallow oil and gas field development, horizontal drilling has become a common method for shallow oil and gas fields in the industry. But because of loose cementation in the shallow reservoir and large borehole size in the deviated section, the drift angle buildup cannot be effectively controlled. Through the study of the build-up rate theory, under the premise of a certain formation build-up rate, the build-up efficiency of the drilling assembly was improved by adjusting the drilling parameters, so that effective well path control was achieved.
