Abstract

The utility model relates to an oil well rig shifter, which consists of an upper rack and a lower rack. The upper rack and the lower rack are provided with two main rails and four auxiliary rails, respectively. The lower rack is fixed on the cement foundation. The upper rack is overlapped on the lower rack, and the upper rack and the lower rack are fixed with a clamp system. The device solves the problem that a cluster well drill is moved in morass and on foreshore. As the drill is arranged on the racks, the entire drill can move in transverse or longitudinal directions along the racks to reach desired locations safely and quickly during movement. In addition, by adopting the utility model, moving equipments are saved; foundation is established for making high quality holes quickly. The utility model is in particular applicable for mass shift of ZJ50DB drill headframe and bed.

Description

A kind of rig moving guide rail

Technical field:

The utility model relates to the oil-well rig mobile device, especially a kind of rig moving guide rail.

Background technology:

Along with the Oilfield developing block is constantly expanded, some oil wells are distributed in the marshland, shallow sea, particularly cluster well is owing to be distributed in this area, well spacing was nearer when removal of home was installed, communications and transportation is very difficult, have a strong impact on drilling progress, a kind ofly for this reason be adapted to partly vertically integral translation and the transverse integral translation of ZJ50DB drilling derrick and base, can satisfy a kind of rig moving guide rail of playing the cluster well needs in certain block, can be safe, quick and easy, reliably make the rig primary module find the strange land well rapidly accurately, be not reported by retrieval.

The utility model content:

The utility model purpose is to overcome above-mentioned shortcoming, and a kind of rig moving guide rail that provides can make each rig of cluster well group carry out on guide rail vertically with laterally mobile, to the borehole position of being bored.

Technical scheme:

The utility model is made up of upper strata guide rail lower floor guide rail, described upper strata guide rail and lower floor's guide rail respectively have two backbones and four auxilliary rails, its lower floor's guide rail is fixed on above the cement ground, the upper strata guide rail overlaps above lower floor's guide rail, and with clamp mechanism upper strata guide rail and lower guideway is fixed together.

In the described backbone, wherein two laying directions with the two other backbone are vertical mutually, and backbone and auxilliary rail are I steel and form through the weldering knot.

The new working method of this practicality is:

At first four beam seats of rig substructure are fallen above the guide rail of upper strata and with clamp mechanism and tightened, when vertically moving, the clamp mechanism of upper strata guide rail is unclamped, laterally clamp mechanism on four crossbeams of base is unclamped when mobile, determine that each position installs the rig that begins the movable base top after reliable.In the process of vertically moving, rig should overlap with two orbit centres of lower floor track across the center, at this moment just can vertically move, and the power that moves just can move on to rig floor any precalculated position from stepping mechanism and liquid cylinder piston by repeatable operation.

The utility model compared with prior art has distinguishing feature:

Because this device is erected at marshland that cluster well is positioned at according to the cluster well characteristic distributions, adopted the mobile system of forming by upper strata guide rail, lower floor's guide rail, like this when rig is moved, just can carry out the whole removal of home of rig by move mode, very convenient, not only saved man-hour, can reduce trucking expenses again, safety, quick, thereby solved cluster well in the marsh, a seabeach removal of home difficult problem.

Description of drawings:

Fig. 1 is the utility model front view.

Fig. 2 is the attached view of the utility model.

Fig. 3 is the clamp mechanism schematic diagram.

Among the figure, 1, the upper strata guide rail, 2, lower floor's guide rail, 3 backbones, 4, auxilliary rail, 5, clamp mechanism forms.

The specific embodiment:

Among Fig. 1, upper strata guide rail 1 two backbones 3 and four auxilliary rails 4 for forming with I steel weldering knot, lower floor's guide rail 2 is two backbones and four the auxilliary rails that form with I steel weldering knot equally, but be cemented in above the cement ground, can guarantee the rig mobile security like this, upper strata guide rail 1 be located in lower floor's guide rail 2 above, this guide rail is used for being located in rig substructure, use clamp mechanism 5 then, upper strata guide rail and lower floor's guide rail are fixed together.

Because rig is located in above the upper rail, like this after boring completion, during mobile rig, if vertically move, rig is just being recognized and can moved to the precalculated position along guide rail at the bottom of with hydraulic cylinder and stepping mechanism rig under the motionless situation of upper and lower guide rail, horizontal when mobile, the guide rail 2 of lower floor is motionless, upper strata guide rail 1 moves along lower guideway 2, can make rig whole mobile, very convenient, without crane and employ the removal of home vehicle, solved again under the situation that the removal of home road do not possess and realized that rig integral moving is that quick high-quality drilling well creates conditions.
