Abstract

A screw power device for a sand suction pump comprises an upper connector, a shell and a lower connector which are sequentially arranged, and an upper substitute connector, a first motor assembly, a cardan shaft assembly, a shockproof transmission shaft assembly, a cardan shaft assembly and a second motor assembly are sequentially arranged in an inner cavity of the shell. The upper substitute joint is fixedly connected with a rotor on the first motor assembly through an anti-drop stabilizing assembly. The anti-falling stabilizing assembly comprises an anti-falling connector, an anti-falling connecting rod and an anti-falling nut. The anti-falling connecting rod penetrates through the anti-falling joint, is connected with the rotor and is locked by an anti-falling nut. Two ends of the anti-drop joint are embedded into a fixed positioning bolt, and the shockproof transmission shaft assembly comprises a bearing assembly shell and a transmission shaft arranged in the bearing assembly shell. A needle bearing and a ball bearing are sequentially arranged at two ends of the transmission shaft. A screw drilling tool is used as a power source, an ideal effect is achieved in a sand fishing process of a lost-return well, and the construction period is greatly shortened.

Description

technical field [0001] The invention relates to the field of sand dredging and workover operations, in particular to a screw power device for a sand suction pump. Background technique [0002] According to the fact that most of the current oilfields have a large loss of original pressure in the middle and later stages of the formation, many lost-return wells use the conventional sand dredging scheme in the sand dredging and workover operations. The construction period is long, the construction cost is high and the success rate is low, which affects the project cycle and efficiency. . Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a screw power device for a sand suction pump, which uses a screw drilling tool as the power source, and achieves an ideal effect in the process of dredging sand in lost return wells, and the construction period is compressed to 1 / 4 of the conve...
