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举足轻重,从而引起高度重视。在地质和地球化学资料基础上,结合高分子力化学分析,阐述了力化学作用的基本特点,沉积盆地中应力分布、成烃力化学作用方式、反应类型、影响因素和实验证据以及力化学作用与油气分布,以推进油气地质理论的完善。

The traditional geology considers that tectonizations mainly control the sediment and hydrocarbon migration and accumulation of petroliferous basins, and the energy of hydrocarbon formation is only heat energy. In recent years, more and more information of geology and geochemistry showed that the tectogenesis play an important role in the hydrocarbon generated directly by mechanochemistry in the process of hydrocarbon formation, so that it has been caused great attention. This paper, based on the information of geology and geochemistry with the analysis of macromolecule mechanochemistry, expounded briefly the essential features of mechanochemistry, which can be divided as two types of high molecular compound and low molecular compound mechanochemistries. The mechanochemistry of ore-forming process consisted of mechanical ionic activation, strain dissolution and stress corrosiveness.
Mechanochemistry processes can dissociate the bonds by the mechanical energy and form activated particles and separate out low molecular compounds. In geology, the horizontal stress is stronger than the vertical stress in the crust, and that can present as tensile stress, tenso-shear stress and so on at different geologi-
cal conditions. These stresses supply the energy source as larger as geothermal to form hydrocarbons from sedimentary organic matters. The experiment of mechanochemistry forming hydrocarbon at normal temperature and differential stresses offered the testimony of mechanochemistry forming hydrocarbons. The
conditions to control the mechanochemistry forming hydrocarbons consist of the present station of organic matters and the geoheat and others. The petroleum distribution in the world also displayed the feature of mechanochemistry forming hydrocarbons on the great scale and most of the major fields distributed the regions of tectonic stress concentration. The formation of the abundant petroleum resources in the Baohai bay basin in China may be caused obviously on mechanochemistry forming hydrocarbons. The mechanochemistry forming hydrocarbons will advance to perfect the theory of petroleum formation.
