试论辽河油田勘探史上的三次意外

On Three Unexpected Circumstances in the Exploration History of Liaohe Oilfields

在辽河油田的勘探开发史上,曾经出现过三次"意外",分别是:面积最大的东部凹陷油藏意外的少;面积比东部凹陷小的西部凹陷油藏意外的多;面积最小的大民屯凹陷油藏意外的多于面积最大的东部凹陷。这三次"意外"提示我们应对传统找油理论进行深刻反思:为何勘探开发的实践结果总是出乎原来的理论预料之外?从无机成油论的角度对辽河油田勘探历史上的"三次意外"做了重新解读,并尝试着探索新的找油思路。

In the exploration history of Liaohe oilfield,there were three unexpected circumstances：the oil storage in the east depression with the biggest area was unexpectedly less;the oil storage in the west depression with less area than the east was unexpectedly much more;the oil storage in Damin village depression with the smallest area was unexpectedly more than that in the east depression with the biggest area. These three unex-pected cases remind us that we should reflect on our traditional oil exploration theory,asking why the practical results of exploration and development are always beyond the expectation of traditional theory. This paper re -explains the ＆quot;three unexpected＆quot; in the exploration history of Liaohe oilfiled from the perspective of inorganic petroleum origin theory,and tries to explore the new thinking way of oil exploration.
