Research Of Gas Chromatography Application Method In Oil And Water Reservoir Valuation

Gas Chromatography is a kind of value technology of geochemistry. This technology is used widelybecause it can depart every component from the gas mixture.Now in Daqing Oil-field, explorating oil and gas is becoming difficult more and more. In the oil andwater reservoirs there is much clay and the reservoir has high penetrability, According to that situation, weuse Gas Chromatography technology. It can help us to identify water in reservoirs.Light Hydrocarbon Gas Chromatography technology is a new reservoir value technology inchina. this technology mainly analyze single chromatography from C1～C9. These single chromatography isaffected by original stone,reservior changingand and their solubility in water. In the same situation, thedifferent solubility of Light Hydrocarbon in the water reflects the oil reservior or water reservoir. UsingLight Hydrocarbon Gas Chromatography technology, veracity can be improved and create better ecnomicprofit.Through studying shape changing and data decreasing of the graph of hydrocarbon gaschromatography and Pr/nC17,Pn/nC18,∑C21-/∑C22+ etc, combining the other data, confirm all theGas Chromatography Parameters' characters of the different liquid, such as oil and water, and set up oil andwater reservoir valuative standard about Gas Chromatography. This peper especially studies how toautomatically conform Light Hydrocarbon component,how to choose the better Gas ChromatographyParameters. At last develop a new software to deal with the Light Hydrocarbon Gas Chromatography data.
