Application of microbiological anomaly in hydrocarbon prospecting of Zhenjing oilfield

By using the microbial prospecting of oil and gas(MPOG)technology,1208 group samples of Zhenjing oilfield have been analyzed.Combined with geological data obtained from the work area,hydrocarbon-bearing area and remaining oil distribution have been forecasted.The results show that in the work area the microbial oil abnormal distribution continuity is good,the average abnormal is high and reservoir control area is larger,which can be divided into four major blocks.The abnormal area is along underwater distributary channel presenting the " winding" distribution,and belongs to the typical lithologic reservoir.At the same time,some areas have been prospected for a long time,while the microbiological anomaly is still obvious,which shows that underground remaining oil is still more,being with the value of further development.
