Embodiment 1

[0027] Cluster Well Drilling

[0028] see figure 1 , figure 2 and Image 6 , First, connect the fixed lugs 7 on the two transport beams 5 with the rig base frame 14 with the fixing pins 6, so that the two transport beams 5 and the drilling rig base frame 14 become a whole, and the four transport beams 5 at both ends of the The cluster well device is connected with the transport beam 5 by the lifting cylinder 3 with the sliding seat. When the drilling rig moves forward as a whole, the four lifting cylinders 3 with sliding seats are pushed out at the same time, so that the supporting disc 17 is supported to the ground, and the base frame 14 of the drilling rig is lifted up at the same time, and then the four are installed in the supporting disc 17 At the same time, the stepping oil cylinder 2 is extended, so that the lifting oil cylinder 3, which is sleeved on the slide rail 1 and connected with the sliding seat, drives the transport beam 5 and the drilling rig base frame 14...

Embodiment 2

[0030] The overall movement of the drilling rig

[0031] see image 3 , Figure 4 and Figure 5 First, connect the connecting lug 18 on the upper part of the hauling tire mounting frame 9 of the whole machine with the lifting cylinder 10, and the other end of the jacking cylinder 10 is connected with the connecting lug 4 on the transport beam 5, and the whole hauling tire The axle mounting seat 11 at the bottom of the mounting frame 9 is connected with the axle 16, so that the whole machine hauling tire mounting frame 9, the axle 16 and the tire 8 are integrated (see Figure 4 ), at this time the tire 8 and the drilling rig base frame 14 are arranged vertically. When the drilling rig needs to be moved as a whole, the jacking cylinder 10 starts to lift. With the extension of the cylinder, the tire 8 slowly rolls close to the wellhead, and the transport beam 5 is also lifted. At this time, the hauling tire of the whole machine is installed The middle connecting lug plate 19 ...

Abstract

The invention provides an integrally moving and cluster well switching device of a drilling machine. The device is provided with two transport beams arranged on a drilling machine pedestal; the transport beams are mutually connected with the drilling machine pedestal through a fixed ear plate welded on the transport beam and a fixed pin; the upper part of each transport beam is respectively welded with a connecting ear plate; the connecting ear plate is mutually connected with the traveling device through a jacking oil cylinder; both ends of each transport beam are respectively provided with a cluster well device; and the cluster well device is mutually connected with the transport beams by using a lifting oil cylinder with a slip seat. The cluster well device comprises a slide rail, a stepping oil cylinder, the lifting oil cylinder with the slip seat and a supporting disk. The traveling device comprise transport tires, an complete machine carrying tire mounting bracket, the jacking oil cylinder and an axle, wherein the upper part of the complete machine carrying tire mounting bracket is provided with a rotary oil cylinder; the rotary oil cylinder is mutually connected with a rotary shaft; the rotary shaft passes through an axle mounting seat arranged at the lower part of the complete machine carrying tire mounting bracket and is mutually connected with the axle; the connecting ear plate arranged at the upper part of the complete machine carrying tire mounting bracket is mutually connected with the jacking oil cylinder; and the connecting ear plates at the middle part and the lower part of the machine carrying tire mounting bracket are respectively and mutually connected with the transport beams.

Description

technical field [0001] The invention relates to the field of oil and mineral drilling rigs, in particular to a device for integral movement of drilling rigs and switching of cluster wells. Background technique [0002] With the increasingly fierce competition in the international drilling operation market, the oilfield side has higher and higher requirements for the operation equipment of the workover contractor, and the operation cost also increases. In order to reduce the cost and improve the work efficiency, more and more drilling rigs now require Realize the overall dragging and convenient realization of cluster well drilling. [0003] At present, the cluster well device commonly used in drilling sites has disadvantages such as complex structure, heavy weight and large number of modules. Before installing the cluster well track, first of all, strict ground leveling requirements must be implemented for the well site. Then install the huge cluster well track and auxiliar...
