Abstract: In allusion to actual demand in emergency dispose of oil leakage in the crossing area of Heilongjiang in Sino-Russia Crude Oil Pipeline and the shortages in common methods of oil fence, a method to section flowing with oil fence for leaked oil is proposed based on fencing and recovering leaked oil in river by oil fence in free of frozen period. This method can effectively improve the utilization rate of oil fence and recovery rate for leaked oil. Comparisons are made between solid float-type and PVC inflatable oil fence, also including forming methods of oil fence with guide plate and pulling ropes. The comparison results can provide reference basis for the processing programs of leaked oil recovery according to actual conditions of crossing area, also a basic data for the future research on the laying of oil fence.
