某井钻柱强度校核 A well drilling column strength check Abstract: Due to a well of 5110 is an one mouthful of horizontal Wells rice. Horizontal displacement is 680 meters. Horizontal distance is 3.8 meters. In drilling process, accident treatment and disadvantages will be inevitably stucked, such as torque operation. Therefore pipe wrest resistant strength is the key parameters. Drill pipe joints wrest resistant intensity is a multivariate function. These variables include steel strength, connector size, thread form, palpitation, taper and surface thread or pre-tightening force and friction coefficient, etc. Drill pipe diameter and inner fittings, in certain extent determine the joints of drill pipe wrest resistant intensity. The intensity checking wrest resistant ensure the hose body wrest resistant yield strength. Pipe structure design decision was designed. Simulated performance, in the same materials , conditions ,and pipe diameter in the same case, different structure size of drill pipe showed what performance is not the same. Therefore, through the structure design of drill pipe calculated and checked the strength that is not just the meaning of practical application. For example, with the pipe failure to explore more reasonable drill pipe research, which is based on the structure design are given in the standard API, based on the results of previous studies. The S135 of a factory for drill physical-chemical properties of the analysis and structural design strength calculation and checking. To drill pipe structure design, currently has a decisive impact performance in use of pipe. Failure is an important subject in the research of drill pipe, which is based on the drill pipe failure analysis that from the perspective of failure in the structural design optimization drill problems that should be paid attention to on the drill pipe structure, in order to put forward some theoretical basis for design . Specific content as follows : 1. Oilfield drilling tools failure sit
