Detailed Description
In order to make the technical solutions of the present invention better understood, those skilled in the art will now describe the present invention in further detail with reference to the accompanying drawings.
As shown in fig. 1-3, an improved safety plug removal device for an oil field fracturing well comprises an oil pipe 1, wherein a guide portion 2 is arranged at an end portion of the oil pipe 1, a recessed portion 21 is arranged at one end, close to the oil pipe 1, of the guide portion 2, a rotating portion 3 and a water splashing portion 4 are respectively arranged on the recessed portion 21 in an axial rotation mode, a plurality of spiral flow guide protrusions 31 are arranged on the outer wall of the rotating portion 3, and the spiral flow guide protrusions 31 are matched with the water splashing portion 4.
Specifically, as can be seen from fig. 1, the interior of the guiding portion 2 in the above embodiment is a hollow structure, and the hollow structure is communicated with the oil pipe 1. Further, an inner caulking groove 22 is formed in the recessed portion 21, a plurality of through holes 23 communicated with the hollow structure are formed in the inner caulking groove 22, an extending portion 32 is formed in the inner wall of the rotating portion 3, and the extending portion 32 extends into the inner caulking groove 22, so that the spiral flow guide protrusion 31 is communicated with the through holes 23. When liquid is sprayed out from the oil pipe 1, the embedded groove 22, the through hole 23 and the spiral flow guide protrusion 31, the sprayed water column can impact on the protrusion parts 7 which are arranged on the outer wall of the water splashing part 4 and distributed in a circumferential array, so that a water arc is excited, and the rotating part 3 can be prevented from rotating at a preset speed.
