Abstract

Abstract:

GC-MS,UV and TSF have been used to measure traces of hydrocarbons (<10^-6)in shallow and surface layers in various areas, such as Lishu of Songliao, Ordos, western Sichuan, Tianchang of Northern Jiangsu and Yakela of Northern Tarim. Vertical micro-migrations of hydrocarbons from subsurface sources have thus been proved, which would result in halo-source relationship of dispersion haloes over the sources. There will be no exception even if the reservoirs are buried at a depth of over 5000m and there are tight seals. Presently, study of the basic principles of geochemical exploration is relatively weak. In view of this situation, we should begin with the observation of geochemical fields at depth, and determine the traces of micro-percolation of hydrocarbons in combination with fine seismic and geologic data, so as to verify different mechanism hypotheses. At the same time, we should also pay attention to dynamic observation of subsurface hydrocarbon micro-percolation, strengthen study of fabric geochemical field and genesis of geochemical anomalies, and speed up the simulation tests of relevant mechanisms.

Key words: halo-source correlation, geochemical exploration, basic principle, anomaly-forming mechanism, geochemical field at depth, fabric anomaly, simulation test, micro-migration
