我队自1978年以来,先后在江汉、冀中、苏北、泌阳、四川、松南、南方碳酸盐地区(包括句容、黄桥)等不同沉积环境、构造单元、地貌单元等研究分散汞的相对富集体,开展石油化探浅层(0.4-1.0米)壤气汞测量与应用。实践表明,天然气均含有较高的浓度的汞,如江汉油田、冀中柳泉气田、泌阳双河和下二门油田、松南红岗油田等,其天然气含汞量(ng/m~3)分别为170—450、147一637、351—684和53—146、200—1600。成为油气田上壤气汞的主要源。地表各种因素虽然对壤气汞的测量有影响,但
Since 1978, our team has studied the dispersion of sedimentary environment, tectonic units and geomorphic units in Jianghan, Jizhong, northern Jiangsu, Biyang, Sichuan, Songnan and Southern Carbonates (including Jurong and Huangqiao) Relative enrichment of mercury, survey and application of soil gas mercury in the shallow layer (0.4-1.0 m) of petrochemical exploration. Practice shows that natural gas contains high concentrations of mercury, such as Jianghan Oilfield, Jiuzhong Liuquan Gasfield, Biyang Shuanghe and Xiaermen Oilfield, Songnan Honggang Oilfield, the mercury content of natural gas (ng / m ~ 3) 170 to 450, 147 to 637, 351 to 684 and 53 to 146, 200 to 1600. Become the main source of mercury in oil and gas fields. Although various factors on the surface have an impact on the measurement of soil gas and mercury,
