地球化学勘查技术在松辽十屋南地区的应用

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

经过研究发现,油气化探在松辽盆地东南隆起区具有较好的应用效果,烃类和蚀变碳酸盐法是该地区比较有效的方法。地球化学测量结果表明,十屋南地区烃类比较活跃和富集,这对在该地区利用地球化学技术寻找油气藏是个有利的前提条件。通过研究,在测区内发现了一些油气化探综合异常,这些综合异常的存在,客观地反映了研究区内具有成油气藏条件。

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.
