Abstract:

Great advances have recently been made in the understanding of HC migration by numerical simulation. To solve HC migration equations, the key lies in differentiating the effective migration zones (x, y, z, t); the crown of abnormal pressure in the sedimentary formation may be consistent with z, t. In this paper, some queries have also been raised to the validity of "differential entrapment" and "large-area water motive power system"。
