APPLICATION OF GEOCHEMICAL EXPLORATION TECHNIQUE IN THE SOUTHERN SHIWU REGION, SONGLIAO BASIN

The oil and gas geochemical exploration technique is a substantive applied science in oil and gas resource exploration. It can be applied in recognition of oil/gas accumulations, trap evaluation and so on. Based on the research results, this technique has quite good application effects in the southeastern uplift region of Songliao basin, of which hydrocarbons and altered carbonates are the more effective indicators. The results of geochemical survey indicate that hydrocarbon is quite active and abundant in the southern Shiwu region, which provides a favorable premise in using the geochemical technique to search oil and gas pools in the region. Through research, we have discovered some integrated geochemical anomalous zones, which objectively reflect that this area has the environment to form oil and gas pools. In addition, the research results in the Houwujiahu area reveal that the oil and gas geochemical exploration technique is also effective in the southeastern uplift region of Songliao basin, which can provide as a guidance of oil and gas exploration in this region.
