Liquid gas electric drilling pumping device

Abstract

The invention discloses a pumping device for liquid-gas electric drilling. It includes a frame, the front of the frame is provided with a rope winch that can be driven by a power unit, and a thin steel wire rope is provided on the rope winch; a pair of bearing seats are provided at the rear of the frame, and a There is a main shaft for supporting the main wire rope drum, and one end of the main shaft is equipped with a large gear, and the large gear is also driven by the power device. The advantage of the present invention is that: when the large rope of the drilling rig needs to be threaded, the large rope of the drilling rig can be easily threaded into the wheel train of the crown block and traveling block by using the rope-threading winch of the device and the thin steel wire rope on it. It improves the rope threading efficiency, shortens the installation time of the drilling rig, saves manpower, and improves the production efficiency at the same time; when drawing the rope, the steel wire rope can be wound on the main steel rope drum at the same time, which simplifies the working procedure. The ropes are all completed on the device at the same time, which simplifies the work procedure and saves time and manpower.

Description

technical field [0001] The invention relates to an auxiliary mechanical device for an oil drilling rig, in particular to a hydraulic-gas electric drilling pumping device driven by multiple energy sources. Background technique [0002] Since the main wire rope of the swimming system of the oil drilling rig is easy to wear and exceed the standard during production, when the steel wire rope needs to be replaced, or when the well is ready to be transferred to a new well site after completion, or when the drilling rig is installed in a new site, it is necessary to replace the main wire rope of the drilling rig swimming system. The wire rope is withdrawn or inserted. Since most of the main wire ropes have a straight diameter of more than 32 mm, and the length is very long, it is difficult to rely on manpower. In the past, when changing the rope, the dead rope was first released and fixed, and the main wire rope was pulled out by using the main drawworks of the existing drilling ri...

AI Technical Summary

Problems solved by technology

When threading a new steel wire rope, first thread a thin steel wire rope or brown rope into the swimming system of the drilling rig, then connect the thin steel wire rope or brown rope with the new steel wire rope, and use manpower or a tractor to pull the other end of the thin steel wire rope or brown rope. The new main wire rope is introduced into the swimming system of the drilling rig; sometimes the old wire rope needs to be used continuously, so the rope drum needs to be placed on a support so that the old wire rope drum can rotate freely, and the old wire rope is mainly wound by manpower and tractors. The old steel wire rope can be threaded into the swimming system of the drilling rig according to the above method on the wire rope drum. The above work requires a lot of time and manpower, and there are unsafe factors at the same time.
