摘　　要：针对胜利海上油田在固井作业中遇到的裸眼长封固段、循环压耗高、地层薄弱的难点,文章主要作了如下几方面的工作:搜集胜利海上油区地质资料,并分析地质资料,清楚埕岛油田、青东区块和垦东区块的地层特点,并考虑从地质和储层物理特性的角度分析影响固井质量的因素。最后,综合上述分析结果,从钻井和固井的角度考虑采取综合性的措施,埕岛油田固井时主要在封固层段的上部采用坂土低密度水泥浆体系,垦东和青东区块的固井主要采用复合纤维增韧水泥浆体系。这些措施均可以有效地解决长封固段、循环压耗高、地层薄弱的固井难题,电测结果表明,所采取的固井措施也可以提高固井二界面的固井质量,保护油气层。According to the long open hole,high circulation pressure and weak formation when drilling in the offshore oilfield of shengli oilfield. This paper mainly does the work as follows: first,collect and analyze the geology materials of the oilfield,then the formation feature of Chengdao oilfield,Qingdong oilfield and Kendong oilfield can be understood,understand the reasons from the perspective of geology and formation physics. Above all,take measures from the perspective of drilling and cementing engineering. Low density cementing slurry can be applied on the top section of Chengdao oilfield. Cementing slurry that contained composite fiber applied on Kendong and Qingdong oilfield. This measures can be solve the problems effectively. The logging result shows that these measures can enhance the cementing quality and protect oil formation.
