Description

Pipe grabbing machine carrying well site pipe rod storage pipe frame

Technical Field

The utility model relates to a pipe support is deposited in well site is retrieved to tubular pole in the workover link among the oil industry field. The pipe grabbing machine has the characteristics of convenience in carrying and transferring, safety, simple structure and strong applicability.

Background

The pipe rod, also called drill rod, is a common device in the petroleum field, and is usually a steel pipe with a thread at the tail part, and is used for connecting the surface device of a drilling machine and the drilling and grinding device or bottom hole device positioned at the bottom end of a well. The purpose of the drill pipe is to carry drilling mud to the drill bit and, together with the drill bit, raise, lower or rotate the bottom hole assembly. The drill pipe must be able to withstand large internal and external pressures, twists, bends and vibrations. In the process of oil and gas exploitation and extraction, the drill pipe can be used for multiple times. The drill rods are divided into a kelly, a drill rod and a weighted drill rod. The connection sequence is square drill rod (1), drill rod (n, determined by well depth), weighted drill rod (n, determined by drill tool combination design). The classification of the drill rods, the drill rod joints, the drill rod specifications, and the steel grade and strength of the drill rods are described in detail.

The light pipe and the raw steel pipe are manufactured into the drill rod after a plurality of processing steps. Firstly, the outer surface of the light pipe is inwards bent through the treatment of a steel pipe thickening process, and the pipe wall of the steel pipe is thickened. Next, the screw is threaded and plated with copper which increases strength. Then, nondestructive quality control inspection is performed, and then welding of the steel pipe body joint is performed. The tube body is then subjected to a welding heat treatment and a welding finish treatment to relieve welding residual stresses. Other tests, including hardness, pressure and non-destructive tests, are performed on the finished steel pipe prior to painting and packaging the finished drill pipe.

In the process of oil exploitation, when a pipe rod used in a workover operation link is transported, the recovered pipe rod is randomly and temporarily stored on a well site due to the limitation of the well site and a transport vehicle. The falling of the pipe rod causes pollution to a well site, and solid wastes such as oil sludge and sand are generated in the process of recovering, cleaning and repairing the falling pipe rod. Meanwhile, in well repair operations, there are often several types of problems:

the first category is complex salvage, which means that the condition of objects falling in the well is very complex due to various reasons in the oil and gas well. Taking an example: the underground pipe column and tools are all stuck by a certain well, and the oil pipe is pulled off when a minor repair crew handles the underground pipe column and tools, so that the well cannot operate and only needs to be handed to a major repair crew for repair.

The second category is the repair of well casing, which is a necessary condition for ensuring the normal production of oil and gas wells, and the well casing damage often occurs due to various reasons, so the repair of well casing is one of the main tasks of major workover crews. The casing damage mainly has the following conditions: firstly, the diameter of the casing is reduced, namely the inner diameter of the casing of the oil well is reduced, so that a downhole tool cannot be used, and the oil well cannot normally produce; secondly, casing rupture, namely the casing of the oil well is ruptured to form a seam or a hole, so that a great amount of stratum sand flows into the well, and the oil-gas well stops production; thirdly, the casing is staggered and broken, some well casings can be broken, and the upper fracture and the lower fracture are staggered.

And thirdly, drilling the inner side of the casing, namely, using a small drill rod with a drill bit to go down from the old well casing, drilling a window (called as window in terms) at a preset position, drilling the small drill bit outwards from the window, drilling a small borehole, then putting the small casing and cementing the well. The project of drilling a section of slim hole completion from the inside of an old well casing to the outside is called old well sidetrack, which is suitable for the following conditions: the lower part of the old well is scrapped and cannot be exploited, and production can be recovered after sidetracking; old well bores have poor oil formation, while well formations are present near the well bore, and new reserves can be recovered after sidetrack drilling.

The problem of storing the pipe rods exists in the three main problems. The problem of storing the pipe rods is that well workover must be considered, and the success or failure of well workover is directly concerned.

For stopping the falling of the recovery pipe pole and reducing the production of oil sludge sand solid waste in the pipe pole transportation process, the field needs a well site pipe pole storage rack that the pipe grabbing machine carried the transportation, and the device should have simple structure, safe and reliable, uses convenient advantage.

The utility model adopts the pipe grabbing machine to carry, which is convenient for the transfer and use of the pipe frame; the length of the pipe support does not exceed the maximum external dimension of the pipe grabbing machine, so that safe walking is facilitated, and a pipe grabbing shovel grabbing port arranged on a pipe support base is convenient to lock and transport; thirdly, adjustable partition piles and side piles are adopted, and the storage quantity of the pipe rods is adjustable; the structure is simple, the well site is not limited, and the safety and the reliability are realized.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a can realize workover in-process pipe pole and transport the pipe support of retrieving the well site and deposit temporarily, solve the well site pollution that the recovery pipe pole falls to the ground to deposit and cause oil pipe pole cleaning in-process oil mud sand solid waste's production. The device adopts the pipe grabbing machine to carry and transport, and the temporary well site storage rack of the double-pivot support pipe pole can avoid the pipe pole recovered in the well repair operation process to fall to the ground to deposit and stop the production of oil sludge sand in the pipe pole cleaning process. The device is characterized in that: firstly, the pipe frame is locked by a shovel grab of a pipe grabbing machine, so that the pipe frame is firmly fixed on the shovel grab; secondly, the length of the pipe support does not exceed the maximum external dimension of the pipe grabbing machine, so that the pipe support can walk safely; thirdly, because the pipe rod separating barrier piles and the side barrier piles are additionally arranged on the pipe frame, the height of the barrier piles can be adjusted according to the field recovery condition by the storage quantity of the pipe rods; fourthly, the problem that the recovery pipe rod falls to the ground to be stored and the production of oil sludge sand in the cleaning process of the pipe rod is avoided.

The specific implementation mode is as follows:

the utility model provides a grab pipe machine and carry well site pipe pole and deposit pipe support, shovels under pipe pole storage rack base, the grab pipe machine and grabs the inserted hole, adjustable pipe pole separates shelves stake, adjustable pipe support side rail stake.

Preferably, the adjustable pipe rod separation fender pile and the adjustable pipe frame side fender pile are respectively provided with a plurality of piles.

Preferably, the pole storage rack base is substantially rectangular with an interior cavity.

Preferably, the size of the lower shovel claw insertion opening of the pipe grabbing machine is consistent with the size of the shovel claw of the pipe grabbing machine.

Preferably, the number of the adjustable pipe rod separation barrier piles is two.

Preferably, the number of the adjustable pipe frame side rail piles is four.

The utility model discloses simple structure, not restricted by the well site, safe and reliable is applicable to on-spot extensive popularization and application.
