摘要: 传统油气地质学认为构造作用主要控制含油气盆地的沉积和油气的运移聚集,而烃类形成演化的能量主要是热能。近年来,越来越多的地质和地球化学资料显示,构造活动对有机质直接成烃的力化学作用在成烃过程中起着重要作用。为了证实构造作用产生的机械能对成烃的力化学作用,本文在系统分析高分子力化学作用、阐述力化学作用基本特点的基础上,应用新方法对不同类型低演化源岩有机质进行了力化学成烃模拟。结果表明,在低温剪切应力作用下,腐泥型有机质发生了明显的非烃向烃类的转化,模拟后样品总烃比例明显增加;而腐殖型有机质不仅发生了可溶有机质中非烃、沥青质向总烃的转化,也发生了大分子烃类向小分子烃类的转化,这表明机械能是有机质成烃演化的重要能量来源,力化学作用可能是有机质早期演化成烃的最主要机制之一。

Abstract: It is considered that the structures control the sediment of gas-oil bearing basins and migration and accumulation and the heat is the main energy of formin g hydrocarbons on the traditional oil-gas geology. Recently, more and more geolo gical and geo-chemical datum show that structural activity is emphasized on mech anochemistral function for organic matter directly generating hydrocarbon during forming hydrocarbon. Then, We simulated mechanochemistral function generating h ydrocarbon to different kinds of low mature organic source matters by a new meth od on systemically analyzing high-molecular mechanochemistral function and givin g basic mechanochemistral characteristics in order to attest mechanical energy s tructural activity generating to mechanochemistral function on forming hydrocarb on. And the result shows, under low temperature shear stress. The sapropelic mat ters apparently presented transformation from non-hydrocarbon to hydrocarbon and total hydrocarbon ratio of samples simulated is clearly added. The humic matter s took on the transformation not only from non-hydrocarbon and bituman to total hydrocarbon in soluble organic matters but also from large molecule to small mol ecule. It shows that the energy for organic matters generating hydrocarbon large ly derived from mechanical energy and the mechanochemistral function is one of t he mechanisms in organic matters early forming hydrocarbon.
