APPLICATION OF GEOCHEMICAL EXPLORATION IN THE ON-GOING DEVELOPMENT OF DAWANQI OIL FIELD, XINJIANG, CHINA
油气地球化学勘探在大宛齐油田滚动开发中的应用

IN a recent on-going development project carried out in Dawanqi shallow oil field, geochemical exploration has been applied, which involves in situ determination of free light hydrocarbons (C_1-C_5)in soil air and absorbed hydrocarbons in soil samples by means of a thermal release procedure.Due to a high sampling density and a reasonable interpretation of the geochemical data, as good as 94.5% of drilling succeed rate was achieved which leads to a considerable increase of oil out put. It is shown that geochemical methods are highly applicable in the on-going development for shallow oil fields.
