Abstract
The utility model relates to a superficial layer horizontal well bushing counterweight which comprises a central post and counterweight blocks, wherein a plurality of annular bulges which are parallel to each other are machined on the outer wall of the central post; the counterweight blocks are a plurality of circular ring stacked and combined structures; each circular ring is formed by oppositely combining and fixedly connecting two semicircular ring components; a groove is formed in the inner side of each circular ring and matched with each annular bulge on the central post. The superficial layer horizontal well bushing counterweight has the effects that (1) the structure is simple and practical, and an effect of flexibly adjusting the dead weight of equipment is achieved; (2) the space occupied by the equipment can be sufficiently utilized; (3) the superficial layer horizontal well bushing counterweight is detachable and is relatively convenient to transport and assemble, and resources are saved.
Description
Technical field
The utility model is for oil and gas probing aid field, specifically a kind of for super shallow-layer horizontal case weight device, and the main weight that presses down sleeve pipe that improves, contributes to super shallow seated groundwater horizontal well to complete smoothly casing job.
Background technology
Super shallow seated groundwater horizontal well is because vertical depth is shallow, and horizontal movement is large, and during setting of casing, the weight of sleeve pipe self is difficult to overcome descending frictional resistance, very difficult at the bottom of sleeve pipe lower going-into-well, need to, by the auxiliary equipment that increases the weight of, improve the weight that presses down sleeve pipe, can complete casing job.The existing sleeve pipe weight device that is applied to super shallow horizontal well is structurally around 1 center steel cylinder, the pressurized equipment that two fixedly forms by flange with 6 solid steel cylinders.This equipment presses down the sleeve pipe being hampered by the own wt of solid steel column, promote sleeve pipe and continue to transfer.The sleeve pipe weight device of conventional levels well is mainly used to solve sleeve pipe and transfers the problem being hampered, but be subject to structural limitations own, there is following problem: 1) equipment is too heavy, because this equipment is the sleeve pipe that utilizes own wt to press down to be hampered, therefore need it to there is larger deadweight, thereby cause equipment must have at the scene the crane of large weight capacity to assist to put between the operating period, put; 2) equipment self-weight is fixed, and can not need to change flexibly own wt according to scene, expends unnecessary resource; 3) compact not in structure design, waste limited usage space.
Utility model content
The utility model is to solve the problems referred to above that prior art field operation exists, and provides a kind of for super shallow-layer horizontal well casing pipe weight device, can be by reducing steel cylinder quantity, and optimizing structure design is reached for sleeve pipe and transfers the object of pressurization.
Of the present utility modelly for super shallow-layer horizontal well casing pipe weight device, comprise central post and balancing weight, the outer wall of central post processes multiple annular projections that are parallel to each other; Balancing weight is that multiple annulus stack combining structure, and each annulus is relatively combined and is connected and fixed by two semicircular ring parts, and each annulus inner side arranges groove, and the annular projection on this groove and central post matches.
Such scheme further comprises:
Between two semicircular ring, connect it can be relatively rotated on one side by plunger, another side is fixed by screw bolt and nut.
At the upper and lower side of central post, connect respectively suspension joint and righting head.
Annular projection and the number of rings of central post outer wall are arranged between 2-30.
The external diameter of central post, suspension joint and righting head is all not more than casing inner diameter.
Effect of the present utility model: this apparatus structure is simple, more efficient, flexibility and the practicality of enhancement engineering operation simultaneously.
1) simple and practical, can reach the effect of flexible modulation equipment self-weight.
2) utilized more fully the shared space of equipment.
3) dismantled and assembled, transport and assemble more convenient, saving resource.

The specific embodiment
Exemplary embodiments 1
With reference to accompanying drawing 1, will describe specific embodiments of the present utility model in detail.
In the middle of this utility model, use a central post 3, on central post 3, be processed with the rank of organizing a performance (being annular projection) more.On central post 3, connect suspension joint 1, under connect righting 4.Central post 3, suspension joint 1 and righting 4 order are threaded connection into utility model axis, and three's external diameter all can not exceed casing inner diameter.
During use, elevator blocks suspension joint 1, by lifting card on tourist bus, and lifting means axis combination simultaneously, and it is temporarily placed in rig floor rat hole.
On rig floor, be ready to balancing weight 2, and balancing weight connection is some right with bolt and nut.Slowly, carry utility model axis, when central post 3 exposes top first ring projection, with pneumatic hoist suspended counterweight piece 2, the groove on balancing weight is inserted in the projection on central post 3 relatively, and connect the interface of balancing weight 2 with bolt, make itself and central post 3 combinations.
In continuation, carry, residue balancing weight is installed successively, until utility model deadweight reaches on-the-spot required weight substantially.
After having assembled, above carry hook until utility model lower end righting 4 is stretched in first sleeve pipe of well head, and slowly transfer hook, make balancing weight contact wellhead casing pipe top bottom, press down the sleeve pipe that is hampered, until in the whole lower going-into-wells of sleeve pipe.
Embodiment 2
Mainly by suspension joint, central post, balancing weight and righting four major part, formed.1) suspension joint matches emhasizer body to be mentioned to be connected with sleeve pipe with elevator and realizes pressurization; 2) central post be steel stub boring quickly, be used for main shaft, and process the projection of ring-type, auxiliary fixing weight; 3) balancing weight is steel annulus, and each annulus structure is divided into two semicircular ring parts, and two semicircular ring combine relatively, and the projection that semicircular ring inner side arranges on groove and central post matches.Between two semicircular ring, connect it can be relatively rotated on one side by plunger, another side is fixed by screw bolt and nut.The difference of annulus internal-and external diameter equals central post diameter, can realize multiple annulus and be layering, and assurance equipment can reach required weight; 4) righting head is connected on central post bottom, can stretch in sleeve pipe, and righting weight device, pressurizes to sleeve pipe.
Simplified embodiment 3
For super shallow-layer horizontal well casing pipe weight device, comprise central post and balancing weight, the outer wall of central post processes multiple annular projections that are parallel to each other; Balancing weight is that multiple annulus stack combining structure, and each annulus is relatively combined and is connected and fixed by two semicircular ring parts, and each annulus inner side arranges groove, and the annular projection on this groove and central post matches.
Above-described embodiment further comprises:
Between two semicircular ring, connect it can be relatively rotated on one side by plunger, another side is fixed by screw bolt and nut.
At the upper and lower side of central post, connect respectively suspension joint and righting head.
Annular projection and the number of rings of central post outer wall are arranged between 2-30.
The external diameter of central post, suspension joint and righting head is all not more than casing inner diameter.
