Abstract: Based on a study of soil environment contamination situation of the Dongying oil?gas exploitation area, the authors have found some regularities:in soil near the well mouth, Cr, Pb and Zn values are relatively high, which, however, tend to decrease away from the well mouth;Cd values are high at the well mouth, and gradually decrease and become stable in soil on both sides of the well mouth;Cr and Zn values are remarkably affected by the pollution of the falling oil, with the influence range within 1 m;Cu, Ni, Pb and As values do not show obvious change with the depth, and only slightly increase at the depths of 80 cm and 1 m;in soil near most wells, the maximum values of saturated hydrocarbon, aromatics, hydrocarbon and asphalt exist at the well mouths, which is consistent with the phenomenon that the falling oil is likely concentrated at the well mouth; the hydrocarbon content tends to decrease gradually with the elapse of the time, which suggests that the longer the exploitation time, the more serious the hydrocarbon pollution.
