对地下裂缝不发育的气井进行二次压裂可以提高产气量。描述了 2口具有深穿透原始裂缝的致密气井通过二次压裂增产的过程。地面测斜仪的监测表明 ,二次压裂诱发裂缝的方位与原始裂缝是正交的。
Secondary fracturing of wells with undeveloped fractures can increase gas production. Describe the process of two stimulation of tight gas wells penetrating the original fractures through secondary fracturing. The monitoring of ground inclinometer shows that the orientation of fractures induced by secondary fractures is orthogonal to the original fractures.
