利用生油岩系中的烃类、沥青质含量等地化指标来定量的评价一个沉积盆地的含油气远景,在技术上还存在许多困难,因为我们所取得的各种地化指标数据,都是生油岩中残留有机质的表征值,而所需要的却是排替值。两者有什么样的关系,怎样由前者通过一定的数理运算来求得后者,是一个还没有解决的课题。要解决这个问题必须弄清烃类由生油岩排替出去的机理。这个问题到目前为止并没有得到解决,且有许多不同的观点,一般趋向于以泥岩压实水作载体把烃类排替出去的机理。本文就从这个观点出发来
Using the geochemical indicators of hydrocarbon and asphaltene content in the source rock series to quantitatively evaluate the hydrocarbon-oil prospect of a sedimentary basin, there are still many technical difficulties because all the geochemical data we have obtained Is the residual organic matter characterization of the source rock, but what is needed is the displacement value. What kind of relationship between the two, how the former through a certain number of mathematical operations to obtain the latter is an unsolved problem. To solve this problem, we must clarify the mechanism by which hydrocarbons are replaced by raw oil rocks. This problem has not been solved so far and there are many different points of view that generally tend to displace hydrocarbons with mud-rock compaction water as a carrier. This article starts from this point of view
