摘　　要：中油(土库曼斯坦)阿姆河天然气工程项目是迄今为止中国石油集团公司在海外最大的天然气项目,是中亚管道的主要气源地,萨曼杰佩气田Sam35-1H水平井是土库曼斯坦阿姆河右岸巴格德雷区块的第一口水平井,其钻探目的是通过水平井实现稀井高产。该构造地层复杂,存在巨厚盐膏层(有的含异常高压盐水),储层压力低(0.98),高含H2S,该井面临水平位移长及盐膏层定向稳斜难等技术难题。Sam-35-1H水平井的成功实施,为同类地层大位移水平井的钻井积累了经验。The natural gas engineering project at the Right Bank of the Amu-Darya River in Turkmenistan,an important source of Trans-Asia Natural Gas Pipeline,is the largest natural gas energy project abroad of CNPC.The horizontal well Sam35-1H in Samantepe gas field is the first horizontal well at the Right Bank of the Amu-Darya River in Turkmenistan.This structure features in Sam35-1H are ultra thick gypsum & salt beds with abnormal high pressure as the roof rock;low pore pressure in the reservoir(only 0.98 pressure coefficient);high content of sour gas.Especially there is no successful example in domestic gas fields to drill such a horizontal well under so complicated geological conditions.However,the long horizontal section will increase the number of the gas channels and improve the productivity.In the paper,the successful application of directional and horizontal well drilling technology in the Right Bank of Amda River was introduced in detail.The successful drilling experience on well Sam35-1H shall be a good example to the long-reach well drilling in the similar gas fields,and has great significance for the gas energy project at the Right Bank of The Amu-Darya River in Turkmenistan.
