摘　　要：冷家油田冷 4 3块S1+2 油层稠油属特稠油 ,5 0℃脱气原油粘度在 10 0 0 0mPa·s以上。通过优选的假单胞菌L1,LH - 18与短杆菌HY - 2 1对冷 4 3块 8口油井进行吞吐试验 ,共增产原油 94 7t。单井最长有效期超过 6个月 ,最高增产原油 2 80t。该研究拓宽了微生物采油在稠油油藏中应用范围 ,为稠油。S 1+2 formation of Leng 43 block of Lengjia Oilfield was a kind of very heavy oilfield with the viscosity over 10,000mPa·s in 50℃. The research tested 8 wells in Leng43 block using pseudo-unicell bacterium L1,LH-18 and short-bacilus HY-21, it increased 947t crude oil, and the longest validity period was more than 6months, increased 280t crude oil maximally. The research developed the appliance range of microbe recovery in heavy oilfield, and provided a new way to transfer development style in heavy and very heavy oilfield.
