ＸＨ—９０１ 井是目前四川德阳新场气田采用水平井方式来开发天然气藏的一口中半径水平井，平均曲率半径２４０ｍ 。该井从７４０ｍ 开始造斜至１ １１９－３７ｍ 入靶，完钻井深１ ４４０ｍ ，垂深１ ０１３－１７ｍ ，水平位移５４９－０９ｍ ，水平段长３２１ｍ ，入靶点井斜角９０－８°，方位角３２９－３２°，投产后日产天然气４－１８ ×１０４ｍ３ ，较同地区直井增产４ 倍，经济效益显著。
Well XH-901 is a mid-radius horizontal well developed by horizontal well method in Xinchang Field, Deyang, Sichuan Province. Its average radius of curvature is 240m. The well began to make a ramp from 740m to 1119-37m into the target with a drilling depth of 1 440m and a depth of 1 013-17m with a horizontal displacement of 549-09m and a horizontal section of 321m with a bevel angle of 90-8 ° into the target. Azimuth 329-32 °, Nissan natural gas 4-18 × 104m3 after production, compared with the same area vertical wells yield 4 times, significant economic benefits.
