设钻柱为柔性杆.采用静水压力法计算泥浆对钻柱的受力影响,按不同的钻井方法及不同的钻井工序进行了钻柱的各井段受力分析与强度计算,并编制了相应的计算软件,对大港油田女MH-l水平井进行了实例计算.计算结果表明.该方法方便可行.
Set the drill string as flexible rod.Using hydrostatic pressure method to calculate the influence of mud on the drill string stress.According to different drilling methods and different drilling procedures, the stress analysis and strength calculation of each well section of the drill string were made and correspondingly Of the calculation software, the Dagang Oil Field female MH-l horizontal wells were calculated by an example.The results show that the method is convenient and feasible.
