摘要
In view of the peculiar physical and chemical properties of CO2 gas accumulation, the author holds that only by integrated application of various data and techniques can CO2 accumulation be effectively recognized. Regional geological analysis and geophysical-geochemical exploration methods should be utilized in an integrated way to evaluate the distribution of non-hydrocarbon gas and then locate objectives for drilling. Non-hydrocarbon chromatographic measurement and infrared CO2 concentration measurement ought to be performed to realize in-situ drilling dynamic detection of the CO2 layer. Gas chromatography is used to test related log parameter data and neutron porosity differential values of nuclear logging density so as to make an integrated interpretation of the CO2 gas layer and recognize CO2 gas effectively. New key techniques for integrated exploration of CO2, such as geochemical method and log, are discussed in detail in this paper.
