Abstract:

Based on the three longitudinal and a transverse geochemistry section data in Xifeng area,the article intends to test
the applicability of acid hydrolysis hydrocarbon to oil exploration in Ordos Basin. By analyzing the interference factors,the
background level and geochemistry threshold on geochemistry data,we established the congruent relationship between unusual
index of soil acid hydrolysis hydrocarbon and deep Chang 8 oil pool in Yanchang deposit. The results show that the unusual
geochemistry index of heavy hydrocarbon is consistent with that of soil acid hydrolysis hydrocarbon methane and correspond
well with the deep Chang 8 oil pool. The high geochemistry unusual level of methane and heavy hydrocarbon geochemical
index often correspond with oilfield scale reserve area or industrial oil flow area,while the lower geochemistry unusual level
always corresponds with areas of bad or no indication of oil and gas.

Key words: Ordos Basin, Xifeng oil area, acid hydrolysis hydrocarbon, geochemistry unusual index, Chang 8
