摘　　要：塔里木盆地塔中一号坡折带奥陶系焦滩复合体灰岩地层压力系数在1.15左右,缝洞发育,硫化氢含量为800～300000 mg/L。为探索该区块的开发方案,股份公司决定先期优选2口井进行控压钻井(简称MPD)实验。主要介绍了控压钻进技术在塔里木油田水平井塔中62-13H井中的实施情况,施工取得了预期的效果,可进一步推广应用。Formation pressure coefficient of Ordovician shoal-reef compound limestone of NO.1 slope break zone in Tarimu basin is about 1.15.Fractures and holes develop there,and the hydrogen sulfide content is 800-300 000 mg/L.In order to pursue the development program in this block,2 wells were chosen to conduct pilot pressure controlled drilling test(MPD abbreviated) by the company.Application condition of pressure controlled drilling technology in well Tazhong 62-13H was introduced. The technology achieved desired results and can be further promoted.
