A ground pipe arrangement device for oilfield minor repair operations

Abstract

The invention discloses a ground pipe rowing device for oilfield minor repair operations, relates to the technical field of oilfield surface pipe rowing, solves the automatic discharge, transfer, and length measurement of pipe strings in the process of lifting and lowering pipe strings in oil field minor repairs, and reduces the labor of workers strength, save labor, and reduce the area occupied by the work site. The main points of the technical plan are: including a storage mechanism, a pipe arrangement mechanism, and a length-measuring and inversion mechanism. The pipe arrangement mechanism is located between the storage mechanism and the length-measuring and inversion mechanism. The pipe storage mechanism includes a first cofferdam, a lifting arm, a top seat, a folding arm cylinder, a folding arm, and a lifting cylinder. The lifting arm and the lifting cylinder are installed on the first cofferdam, and the top seat is installed on the first cofferdam. On the upper end of the lifting arm, and the lifting arm is movably connected with the first cofferdam and the top seat, the fixed end of the lifting cylinder is hingedly connected with the upper end of the first cofferdam, and the output end of the lifting cylinder is connected with the lifting The side walls of the arm are hingedly connected, and there are two folding arm hydraulic cylinders and two folding arms.

Description

technical field [0001] The invention relates to the technical field of oilfield ground pipe arrangement, in particular to a ground pipe arrangement device for oilfield minor maintenance operations. Background technique [0002] In order to avoid confusion and damage to the pipe strings that are pulled out or run into the well during minor repair operations in the oilfield, the pipe strings must be arranged in an orderly and orderly manner on the pipe rack after being pulled out of the well or before being run into the well; The standardized discharge is carried out in the way of "layered discharge, one out of ten". After the pipe string is discharged, the length needs to be measured manually. [0003] However, the traditional manual work requires the cooperation of multiple people to discharge the pipe string. In addition, during the discharge process, it is necessary to manually push, pull, and lift the pipe string. Column layering is time-consuming, labor-intensive, and l...

Problems solved by technology

[0003] However, the traditional manual work requires the cooperation of multiple people to discharge the pipe string. In addition, during the discharge process, it is necessary to manually push, pull, and lift the pipe string. Column layering, time-consuming and labor-intensive, high labor intensity, low operating efficiency

After the pipe string is arranged on the first floor, three people are required to cooperate to measure the length. Two people measure, and one person records and calculates. oil pollution, the placement of the cofferdam is time-consuming and laborious, and it occupies a large area after placement
