摘要
通过对特殊螺纹套管现场下井监督指导、跟踪调查,获得了四川地区套管的主要受力情况。对套管柱井内载荷计算数学模型的对比分析,指出适合西南油气田不同井可以采用不同的载荷数学模型进行套管强度设计,从而为不同区块施工井提供相配套的套管,降低套管失效事故的发生。
Based on well under special thread casing site supervision and tracking survey,the main force of casing in Sichuan area is obtained. For casing wells,a mathematical model of load calculation comparison and analysis points out that suitable for southwest oil and gas wells can be used in a different load mathematical model of casing strength design,which can provide matching for different block construction well casing,and decrease the casing failure accidents.
