through studying the rock pyrolysis parameters,the stable isotope and elemental composition of kerogen,the coal sample constituent,group composition and normal alkane,it is thought that most of the organic matters belong to the Type Ⅱ B;
通过对岩石热解参数、干酪根稳定同位素和元素组成、煤样组成、族组成和正构烷烃的研究,认为有机质类型绝大多数都属于Ⅱ B 型;
The second step is to calculate the recovering coefficient by contrasting the pyrolysis parameters in the critical points of different types of analyzed samples.
Combined with geological log, electrical logging and testing data, this paper screened out the pyrolysis parameters for identification and evaluation of oil reservoirs in Jianghan basin through the analysis of 130 sandstone reservoir samples having various oil bearing grade from Xingouzui Formation of 25 wells in 5 oil blocks of Qianjiang depression.
Based on the study of the pyrolysis (Rockeval) parameters and their correlation with the organic carbon content in coalbearing strata,the relationships among the pyrolysis parameters and organic carbon are analyzed. It is considered that the pyrolysis parameters and organic carbon content have the wider variation ranges,and there are some correlation among the different pyrolysis parameters.
The S_1 of debris or sidewall-sampling samples is corrected by the equation of the given stratum. The corrected pyrolysis parameter of S_1+S_2 could describe hydrocarbon-besring property of the reservoir bed more objectivdy.
In addition, the characters of retention hydrocarbon evolution simulated by chloroform bitumen "A" or pyrolysis parameter S 1 are not very reliable either.
Pyrolytic parameter is used to establish the quantity evaluative method on estimating oil saturition, Viscosity of petroleunu Density of crude oil, it is important significant to Detailed survey, oil and gas geological reserves .
On the assumption that seepage of reservoir accords with Darcy's Law and introducing comprehensive productivity factor , the formula for forecasting reservoir productivity is derived through reservoir pyrolytic parameter.
A thorough study on it has been made using optical kerogen parameter, pyrolytic parameter, hydrocarbon constituent and biomarker parameters and nearly 20 geochemical indexes. The hydrocarbongenerating threshold depth in this area is 2500m, the peak of hydrocarbon generation is at the depth of 3000~4200m.
In the light of the definition of oil-bearing grade the authors calculated the theoretical relative distribution of S1+S2 of different oil-bearing grade which later on was proved.
The role of important pyrolysis parameters like peak temperature and heating rate on the tar yield was investigated.

The paper mainly deals with calibration of parameters for pyrolytic chromatography. In actual cases, the authors have selected 61 source rock samples of various types to do simulating experiments, and the parameters obtained from the experiments were compiled to draw a calibration plate for S1 and S2. The plate is clear and easy to use,which would be valuable for correct application of pyrolytic parameters.
