按照地层内的天然应力,裂缝的翼部沿相反方向从井筒向外延伸。
The wings of the fracture extend away from the wellbore in opposing directions according to the natural stresses within the formation.
一种井系统,包括:主井筒,其从地面朝向地下区域延伸;
A well system includes a main wellbore extending from a terranean surface toward a subterranean zone.
通过研究发现,水力裂缝方位不但与井筒在现场地应力场中的方位有关,而且主应力的大小也会影响到裂缝的延伸情况。
The results show that hydraulic fracture propagation is not only related to the orientation of borehole in the stress field, but the magnitude of principal stresses.
