| 摘 要： | 为了控制套管损坏,结合大庆油田南二区构造特征建立了数值模拟模型,应用STSA有限元软件包,模拟了该区地层压力与流动压力界限,地层形变与地层压力的变化关系、单井流动压力与地层形变的关系等,分析了影响套管损坏的基本因素。根据所研究的成果,对该区采取了相应套管损坏治理措施。

| Abstract: | In order to control the casing damage,a numerical model to simulate casing damage in south II zone of Daqing oilfield was set up based on the geological characteristics,and the limits of the stratum pressure and flow pressure,and the relations between single well flow pressure and layer deformation were simulated using STSA finite element software package.Influence factors of casing damage were analyzed,and the corresponding counter-measures have been adopted to control the casing damage based on the study result. |
