为了准确地查明油气聚集的真实过程,需要建立古地质模型。这项工作的第一步,是求出沉积层的古厚度。本文所叙述的恢复古厚度的方法是一种数值模拟方法。这种方法以沉积压实原理和实测资料作为基础。试算结果表明,计算值与已知值相差甚小,其精度可以满足地质研究以及实际勘探工作的需要。
In order to accurately identify the actual process of oil and gas accumulation, the need to establish an ancient geological model. The first step in this work is to find the ancient thickness of the sediments. The method of restoring ancient paleontology described in this paper is a numerical simulation method. This method is based on the principle of sediment compaction and the measured data. The trial results show that the calculated value is little different from the known value, and its accuracy can meet the needs of geological research and actual exploration work.
