本文以川北侏罗系大安寨段介屑灰岩成岩作用研究为例,应用流体包裹体资料不仅可以确定成岩作用产生的温度范围,而且可以依据温度范围来划分成岩作用阶段,推算成岩作用发生时间以及结合沉积史来推算古地温史。少量含烃包裹体的初步研究还可以确定大安寨段油气运移方向和发生时间。

In the Paper, the study of clastic-coquina diagnesis in Daanzhai Member of Jurassic of Northern Sichuan is taken as an example. With the application of fluid enclosure data, the temperature range resulted in diagnesis can be determined; on the basis of which the stages of diagnesis may be distinguished, and the time when the diagnesis occurred and palaegeothermal history as a function of sedimentary history can also be predicted. The direction and the dating of hydrocarbon migration will be determined by a preliminary study of a few hydrocarbon-bearing enclosures.
