Multifunctional tower capable of supporting injection head to move and replacing tools and using method of multifunctional tower

Abstract

The invention relates to a multifunctional tower capable of supporting an injection head to move and replacing tools and a using method of the multifunctional tower, and belongs to the technical field of oil field equipment. According to the technical scheme, a supporting frame (5) is welded in a top-layer telescopic tower (1), the supporting frame is of a rectangular frame structure formed by welding a plurality of square pipes (21) and square pipes (20) with holes, the square pipes are welded to form two symmetrically-arranged side frames, the number of the square pipes with the holes is four, every two square pipes with the holes form a group, and the two groups of square pipes with the holes are arranged between the two side frames in an up-down parallel mode. A tool suspension assembly is arranged between the two square tubes with holes at the upper part; and a blowout prevention pipe fixing assembly is arranged between the two square pipes with holes at the lower part. The height of the telescopic tower can be adjusted, and the telescopic tower is suitable for various environments; the top-layer telescopic tower is provided with the tool hanging assembly and the blowout prevention pipe fixing assembly which can fix a tool and a blowout prevention pipe and are used for tool replacement, repeated lifting of an injection head is avoided, and operation time and cost are saved.

Description

technical field [0001] The invention relates to a multifunctional tower capable of supporting the movement of an injection head and replacing tools and a method of using the same, belonging to the technical field of oilfield equipment. Background technique [0002] At present, when the injection head needs to work in the oil field, the injection head is hoisted by hoisting equipment, and the injection head is fixed with a crane and a rope. This fixing method has potential safety hazards. When the long tool connected to the injection head needs to be replaced in the working state, it is necessary to hang the injection head with a hoisting device for replacement, which is very dangerous and inconvenient to replace the long tool. When the injection head fails and needs to be repaired, the injection head needs to be put back on the ground with lifting equipment for maintenance. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a multifunctio...
