粘土矿物对干酪根热解生烃过程的影响

EFFECT OF CLAY MINERALS ON HYDROCARBON FORMATION DURING KEROGEN PYROLYSIS

本文把干酪根与伊利石、蒙脱石、高岭石３种粘土矿物按一定比例混合，采用分步热解法进行实验。结果表明，粘土矿物对干酪根热解烃的化学组成、产率有很大影响，但不同矿物影响程度不同。本文还对粘土矿物在干酪根向烃转化过程中的作用机理进行了讨论。

Pyrolysis products of mudstone and their kerogens differs greatly in their characteristics, this shows that some roles are played by some minerals during the process of oil and gas evolution from kerogens. Former studies show that clay minerals are the main factor. In order to study the effect of clay minerals on the generation of oil and gas kerogens are mixed With illite, montmorillonite and kaolinite at different preportions and then pyrolyzed step by step. Results show that both chemical compositions as well as R. of hydrocarbons generated are affected by clay minerals greatly, and the degree of affection differs with difference mineral compositions. Based upon the experimental results the role played by clay minerals and their mechanism in chemical reactions in the process of hydrocarbons generation are discussed.
