专刊 天然气开发技术 5 水平井地质导向技术 在复杂薄层特低渗气藏中的应用 ———以苏里格气田某区为例 李玉城 中石油长城钻探工程有限公司地质研究院 摘要：水平井在提高单产、迅速建产和老区挖潜方面优势巨大,而水平井地质导向技术的迅 速发展，使水平井大幅度提高储层钻遇率和整体开发油气田成为可能。地质导向涉及多学科， 多工种，技术密集，专业性强。本文从设计、着陆入靶，水平 钻进各个实施阶 ，详细阐述 了各环节着重需要重视的问题，提出了较完善的导向思路：精雕模型，实时对比，把握着陆； 随钻录井，更新模型，修正认识，及时调整。举HW 井实钻为例加以说明。本区采用地质导向 技术，平均砂岩钻遇90% ，有效储层钻遇率64% ，并结合后期的压裂改造等技术措施，取得了 较好的开发效果。 关键字：水平井 地质导向 模型更新 压裂 Application of geologic steering technique of horizontal well in complex thin layer and low permeability gas reservoir — A case from a district in Sulige gas field Li yu-cheng Geology Institute of CNPC Greatwall Drilling Engineering Company Limited Abstract : Horizontal wells have great advantage in improving individual well producing rate, rapidly establishing productivity and excavating the potential of the old producing area. The rapid development of geologic steering technique of horizontal well make it possible to greatly improve the reservoir drilling rate and overall develop oil and gas fields. Geologic steering involves multiple disciplines and many types of work, intensive technology, highly professional. From the design, landing into the target to horizontal drilling, the paper expounds emphatically the problems needed paying high attention to in each stage of the drilling implementation, and puts forward the relatively perfect thought of geologic steering: carve model, real time contrast , grasp the landing poin
