The invention relates to a quick-mounting type high pressure petroleum drilling and exploration rubber pipe, which comprises a rubber pipe body and a pipe joint, the pipe joint is connected with the end part of the rubber pipe body, and comprises a joint core rod, a transition section, an annular retaining shoulder and a joint, the joint core rod is inserted in an end opening of the rubber pipe body, the transition section is connected with the joint core rod, the annular retaining should is connected with the end part of the transition section, the joint sheaths the transition section, the outer wall of the joint is annually provided with two symmetrical locking blocks, one side surface of each locking block is provided with a groove, and the joint core rod, the transition section and the annular retaining shoulder form an integral structure. The quick-mounting type high pressure petroleum drilling and exploration rubber pipe has the advantages that by adopting the design, the pipe joint is combined with the rubber pipe body, so the purpose of quick connection is realized, and the slippage of joint threads is effectively avoided when the joint is tightened.
Description
technical field [0001] The invention relates to the field of oil production equipment, in particular to a fast-loading high-pressure oil drilling rubber hose. Background technique [0002] The existing oilfield drilling rig supporting special vehicles for well logging, well testing, and well repairing are equipped with corresponding steel pipes, which extend downhole to drive related equipment to work. The total amount of other supporting facilities except the drilling rig is about 11 million to 20 million yuan. . At present, almost all major domestic oil fields use imported products to work, and the investment is huge. The currently used petroleum hose joints are cumbersome to connect, and the joints are rotated many times, which may easily cause damage to the external threads of the joints, so that the joints need to be replaced, resulting in an increase in cost. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order...
