| 中文摘要:2016年，在祁连山冻土区完成了天然气水合物试采水平对接井钻井施工，针对不同井段分别制定了合理的钻进参数及泥浆配方，采用MWD技术及慧磁中靶导向系统，实现了小曲率半径下精准对接，将水平对接井钻井技术成功应用于水合物试采，取得了良好的效果。水合物试采对接井钻井施工不同于可溶性矿藏，其对接精准度要求更高，施工难度更大，主要介绍了水合物水平对接井钻井施工工艺的相关内容。 |

| Abstract:In 2016, trial-producing horizontally butted well of gas hydrate was carried out in permafrost area, Qilian Mountain. Reasonable drilling parameters and mud formula have been made according to the different well sections. Precise docking has been realized under small curvature radius by using the MWD technology and SmartMag target-hitting guide system. Drilling technology of horizontally butted well has been successfully applied to gas hydrate trial-producing and good results has been achieved. The drilling construction of horizontally butted well for gas hydrate trial-producing is different from that for dissolvable minerals, which requires a higher accuracy on connection and is also more difficult to be put into effect. This paper mainly introduces the drilling construction technology of horizontally butted well for gas hydrate trial-producing. |
