数值试井在水平井中的应用

数值试井就是试井问题的数值求解,模拟出无法用解析解表达的复杂油藏和流动阶段,使得解释模型更加符合实际情况,解释结果更加准确。数值试井在直井中已经有了较好的应用,在水平井中应用时要注意与直井参数的正确设置。从本例来看,数值试井在水平井中得到了较好的应用。由于数值试井解释时,多解性增加,因此必须与地质条件进行很好的结合,才能得到真实可靠的结果。

Numerical well test in horizontal well application

Numerical well test is the numerical solution for a well test problem, which simulate cannot use analytic solution expression of complex reservoir and flow phase. Thus it makes the interpretation model is more consistent with the actual situation. The interpretation of the results is more accurate. Numerical well testing in straight wells has better application, the attention of parameters setting. in horizontal well and vertical well applied to From this example. Numerical well test interpretation in horizontal wells has better application. Due to the numerical well test interpretation, multiple solutions to increase, it must be with geological conditions which are very good union, in order to get reliable results.
