Description

TECHNICAL FIELD

[0001] The utility model belongs to oil and gas drilling technical field, specifically, relate to a kind of multi-tubular column automatic separation and conveying device. BACKGROUND

[0002] In the process of oil drilling, hundreds of drill pipes, casings, drill collars and other tubular columns need to be frequently transported, discharged, tripped in and out of the drilling platform, and other operations. The tubular column handling operation of conventional land drilling rigs accounts for more than 30% of the total drilling operation time. Most of the traditional tubular column operation methods rely on 4-5 on-site drilling workers to directly contact the tubular column and use pushing, pulling, dragging and supporting operation methods. Especially during continuous operation, the repetitiveness of these operations reduces the attention of workers, which easily leads to fatigue and even fatal accidents. Tubular column handling operation is the most labor-intensive, most dangerous and most accident-prone operation in the process of oil drilling. According to the statistics of IADC (International Association of Drilling Contractors), 16 out of 23 oil drilling personnel death accidents occurred during tubular column handling operation, accounting for nearly 70%. In terms of the bidirectional reciprocating transportation process of the drilling tubular column on the drilling platform surface, most of them are currently transported by single pipe, which is time-consuming, low in efficiency and poor in safety. The main transportation process is as follows:

[0003] (1) The pipe string is transported upward from the drilling ground pipe string stacking area to the drilling rig floor: the drilling workers on the ground below the drilling floor first push the pipe string placed on the pipe rack in the drilling ground pipe string stacking area to the fixed catwalk V-shaped groove in front of the drilling rig base, then the drilling workers put one end of the steel wire rope lifting tool under the coupling of the pipe string, and inform the drilling workers above the drilling floor that the pipe string is ready for the next operation. There are generally at least 3-4 people above the drilling floor, one person operates the pneumatic winch to slide the pipe string along the catwalk middle V-shaped groove, and then lifts it upward from the V-shaped groove in the middle of the slope; one person above the drilling floor fixes one end of the generally soft rope above the slope end rail, winds several turns around the other end rail, and instructs the drilling worker operating the pneumatic winch to operate. Since the lifting point of the pneumatic winch is above the drilling floor, the pipe string will have a forward inertia instantaneously when it leaves the slope, at which time 1-2 drilling workers beside the rail pull the rope around the other end rail with force to reduce the forward buffer force of the pipe string, and gradually loosen the rope to let the pipe string continue to move forward slowly, then use a tool or directly use inertia to push the pipe string to the top of the mouse hole on the drilling floor, the drilling worker operating the pneumatic winch sees this and loosens the pneumatic winch, the pipe string falls into the mouse hole, then the pipe string is clamped with a lifting clamp and the steel wire rope lifting tool is removed, thereby completing the transportation process of a single pipe string from the ground to the drilling floor. The steel wire rope lifting tool is removed from the last pipe string, slides down the slope to the catwalk to perform the next pipe string upward transportation operation, until all the pipe strings on the ground pipe rack are transported upward to the drilling floor and drilling is completed.

[0004] (2) The pipe string is transported downward from the drilling rig floor to the drilling ground pipe string stacking area: this operation requires the use of two pneumatic winches to complete the entire process, the top of the pipe string is first hooked by the pneumatic winch on the drilling floor, then the bottom of the pipe string is hooked by the other pneumatic winch, the pipe string is pushed outward to the V-shaped groove in the middle of the slope, then the pneumatic winch is operated to slide the pipe string along the V-shaped groove of the slope into the fixed catwalk on the ground, two pneumatic winches are needed to cooperate to slide the pipe string to the tail of the fixed catwalk to the appropriate position. Finally, the steel wire ropes of the two pneumatic winches are removed, and the workers push the pipe string from the V-shaped groove of the catwalk back to the pipe rack. Repeat the above operation until all the pipe strings on the drilling floor are transported to the pipe rack.

[0005] From the above pipe string conveying process can be known: the whole pipe string conveying operation needs at least 4-5 drilling workers to cooperate to complete, the whole operation time is also long, there are problems such as great labor intensity, low efficiency, high danger, prone to accidents of drilling tools rushing out of the catwalk or ramp to hurt people, pipe string threads are easily worn and damaged by sliding on the catwalk or ramp in the process of conveying up and down, shortening the service life of the pipe string, seriously affecting the connection with another pipe string, thereby delaying the drilling engineering progress, leading to the increase of drilling cost. Especially with the development of oil exploration and development work, the drilling depth and difficulty are increasing, the number of wells with drilling depth or displacement exceeding 9000 meters or even 15000 meters is increasing, and at least 900-1600 pipe strings (including drill pipes, casings, drill collars and the like) need to be conveyed according to the average length of 9.5 meters of the pipe string, so the workload of such repetitive pipe string operation is more heavy, and the danger is more intensified.

[0006] In order to solve the above problems, people have actively explored and strived for many years, and various forms of drilling pipe string automatic conveying devices, also known as power catwalks or automatic catwalks, have been put forward. Compared with the conventional catwalks which are usually fixed, the automatic catwalk is an important part of the pipe string automatic handling system, is used for conveying the drilling pipe string from the ground to the drilling platform and lowering the drilling pipe string from the drilling platform to the ground in the drilling operation, is an automatic operation device, has advantages such as high degree of automation, less required personnel, light labor intensity, small workload, less damage to pipe string threads, good safety, etc., can improve labor efficiency, reduce drilling cost, solve the intrinsic safety problem of the drilling site, and is widely welcomed by the drilling site.

[0007] In the prior art, the drilling pipe string automatic conveying device or power catwalk can basically solve the problems of poor safety, great workload and high labor intensity of the conventional fixed catwalk, but still has many problems, such as conveying only a single pipe string each time, low conveying efficiency, high overall energy consumption, frequent action of components, and short service life of the equipment.

[0106] The utility model will be introduced below by means of the drawings.

[0107] Figure 1 The structure of the multi-column automatic separation and conveying device 100 according to the utility model is shown. As shown in the figure, the multi-column automatic separation and conveying device 100 comprises a conveying frame 1, and the central axis of the column is parallel to the length direction of the conveying frame 1. Figures 1-21

[0108] A V-shaped groove 3 is arranged along the length direction of the conveying frame 1, and the V-shaped groove 3 is located inside the conveying frame 1, and the length direction of the V-shaped groove 3 is parallel to the length direction of the conveying frame 1. The V-shaped groove 3 has a lowest point, and under the action of the V-shaped groove 3, the column can automatically roll to the lowest point of the V-shaped groove 3 under the action of gravity after being placed into the V-shaped groove 3.

[0109] A plurality of automatic stop lever mechanisms are sequentially arranged in the conveying frame 1 from left to right, and the automatic stop lever mechanisms are configured to move up and down relative to the V-shaped groove 3, thereby achieving the limiting of the column in the V-shaped groove 3. In this embodiment, the plurality of automatic stop lever mechanisms are respectively a first side edge automatic stop lever mechanism 4, a second side edge automatic stop lever mechanism 5, a first middle automatic stop lever mechanism 6, a second middle automatic stop lever mechanism 7, a third side edge automatic stop lever mechanism 11, a fourth side edge automatic stop lever mechanism 12, a third middle automatic stop lever mechanism 13 and a fourth middle automatic stop lever mechanism 14.

[0110] Among them, the second side edge automatic stop lever mechanism 5, the second middle automatic stop lever mechanism 7, the first middle automatic stop lever mechanism 6, the first side edge automatic stop lever mechanism 4 are the first group of automatic stop lever mechanisms, sequentially arranged in the conveying frame 1 from left to right and located at the rear part of the conveying frame 1, the spacing between the first middle automatic stop lever mechanism 6 and the second middle automatic stop lever mechanism 7 is configured to accommodate only the diameter of one column, the spacing between the second side edge automatic stop lever mechanism 5 and the second middle automatic stop lever mechanism 7 is configured to accommodate at least the diameter of one column, and the spacing between the first middle automatic stop lever mechanism 6 and the first side edge automatic stop lever mechanism 4 is configured to accommodate at least the diameter of one column.

[0111] ​The structure of each automatic gear lever mechanism is the same, and each includes a block 405. When the column needs to be limited, the block 405 is located above the V-shaped groove 3, and when the column does not need to be limited, the block 405 is located below the V-shaped groove 3. Further, the automatic gear lever mechanism includes a block limiting seat 407 located below the V-shaped groove 3, the block 405 is hinged in the block limiting seat 407, the hinging axis is perpendicular to the vertical plane in which the length direction of the V-shaped groove 3 is located; a cylinder support 401 located below the V-shaped groove 3; and a flat push cylinder 403, both ends of the flat push cylinder 403 are hinged with the block 405 and the cylinder support 401 respectively. The flat push cylinder 403 can drive the block 405 to rotate relative to the block limiting seat 407 through extension and retraction, so that the block 405 can be moved to the upper and lower sides of the V-shaped groove 3 in the process of rotation.

[0112] The vertical inclined block mechanism assembly is arranged in the conveying frame 1, and is configured to move up and down relative to the V-shaped groove 3. When the vertical inclined block mechanism assembly moves upward relative to the V-shaped groove 3, the vertical inclined block mechanism assembly lifts and separates the plurality of columns in the V-shaped groove 3. When the vertical inclined block mechanism assembly moves downward relative to the V-shaped groove 3, each of the separated columns falls into the adjacent automatic gear lever mechanism. In this embodiment, the vertical inclined block mechanism assembly includes a first vertical inclined block mechanism 8, a second vertical inclined block mechanism 9, a third vertical inclined block mechanism 15, and a fourth vertical inclined block mechanism 16.

The third vertical inclined block mechanism 15 and the fourth vertical inclined block mechanism 16 are a second group of vertical inclined block mechanism assemblies arranged at the front of the conveying frame 1.

[0114] The structure of the vertical inclined block mechanism is the same, and each group of vertical inclined block mechanism assemblies includes two inclined blocks 803 arranged in reverse and staggered front and back, that is, each vertical inclined block mechanism 8, 9, 15, 16 includes an inclined block 803. The inclined block 803 is configured to move up and down relative to the V-shaped groove 3, and the distance between the highest positions of the two inclined blocks 803 is configured to only accommodate one column.

[0115] In a preferred embodiment, a top block 804 is arranged at the highest position of the inclined block 803, and the top edge slope of the top block 804 is greater than the top edge slope of the original highest position.
