FUZZY EVALUATION APPLIED IN GEOCHEMICAL EXPLORATION OF OIL AND GAS
JIANG Tao, CHENG Jun (The Centre of Geochemical Exploration, CNSPC, Hefei 230022, China)
The treatment and synthetic evaluation of the geochemical exploration index of oil and gas are an important composition of the geochemical exploration work of oil and gas, and immediately linked to the effect of it used for prospecting oil and gas field. A fuzzy evaluation is undertaken by using the fuzzy relationship principle of fuzzy mathematics, in combination with the regular changes of index concerned with the top of or the reservoir of oil and gas itself in the known prospecting area to find out the information reflecting the attibute of the reservoir and set up fuzzy evaluation system with reference to geological data for appraising the anomaly of the index.
