Abstract

Based on a study of regional stratigraphic development characteristics, the authors hold that the Upper Paleozoic in the central and southern part of the Da Hinggan Mountains has a good prospect for oil and gas exploration. In this study, stratigraphic physical specimens were systematically collected from Jarud basin, Tuquan basin and Ulanhot area, and density, magnetization and resistivity were analyzed. Combined with the previous character research data and the results of this work, the petrophysical parameters of the strata in Jarud basin, Tuquan basin and Ulanhot area were systematically sorted out, and the petrophysical interface of the strata in Linxi formation of the Upper Paleozoic was emphatically analyzed, thus providing basic data for the non-seismic geophysical survey in this area. A comparative study of two aspects of paleogeographic environment and physical characteristics shows that the hydrocarbon source rock strata of Linxi Formation in three areas are different. It is considered that the conditions for the formation of hydrocarbon source rock in Tuquan basin area are relatively favorable and, in addition, the degree of slatinization of mudstone is low, suggesting that this area is the most favorable area in the search for hydrocarbon source rock of Linxi Formation.

Key words： central and-southern part of the Da Hinggan Mountains source rock rock physical properties Linxi Formation
