摘　　要：大港油田千米桥潜山板块布井较少,所收集的资料相对较少。此区块断层、不整合面较多,极易发生井漏;沙河街组压力系数在0.97-1.16之间,可能存在异常高压,存在井喷、溢流风险,并且在奥陶系含相对较高浓度硫化氢给钻井增加一定的风险。为探明评价奥陶系上马家沟组油气层的潜力,大港油田布井板深16-21井。There are few wells in Qianmiqiao buried hill plate of Dagang Oilfield,and the data collected are relatively few.There are many faults and unconformities in this block,which is prone to well leakage;The pressure coefficient of Shahejie formation is between 0.97-1.16.There may be abnormal high pressure,blowout and overflow risks,and the relatively high concentration of hydrogen sulfide in the Ordovician system increases the risk of drilling.Well Banshen 16-21 is arranged in Dagang Oilfield to prove and evaluate the potential of upper Majiagou formation of ordovician.
