Abstract

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.
