Problems solved by technology

[0004] The purpose of the present invention is to overcome the disadvantages of the existing medium and large drilling rigs, such as large workload, long working process and the need for a crane, and provide a drilling rig that can be easily and quickly disassembled to meet road transportation requirements after a little disassembly. It is stipulated for long-distance transportation, and it can also move directly between short-distance well locations as a whole, so as to improve the efficiency of drilling rig transfer

Embodiment Construction

[0043] Below in conjunction with accompanying drawing, drilling rig of the present invention and its moving method are further described.

[0044] 1. Quickly disassembled drilling rig:

[0045] Referring to Fig. 1 and Fig. 2, the drilling rig includes a side seat 1 and a side seat 2 with a derrick foundation 5 having a symmetrical structure, a turntable skid 3, and a derrick 39, and the turntable skid 3 is slidably connected between the side seat 1 and the side seat 2 to form a base. The derrick foundation 5 is parallel and symmetrical to the turntable skid 3. In order to strengthen the rigidity and firmness of the drilling rig, the connecting rod 4 with a length adjustment mechanism is movably connected between the two side seats, and one or several tie rods 25 are connected at appropriate places. A slideway 15 is provided on the derrick foundation.

[0046] Referring to Fig. 3, the side seat includes a top assembly 6, a bottom assembly 7, a support truss 8, a first lifting ...

Abstract

The invention relates to a drilling machine that can be removed and installed fast, and the moving method. The drilling machine is made up of two side bases that have symmetrical structure and the base constituted by rotary ripping bar sliding connecting between them. Oil cylinder is set on the side base and the gallows frame is connected to the top of the side base. If the drilling machine needs to be moved for a long distance, it would be moved following the tow truck. The process includes: folding the base, laying down the gallows frame, towing rotating ripping bar by winch and pulley block. The drilling machine is decomposed to four parts, thus it could be transferred easily.

Description

Technical field: [0001] The invention relates to the technology of quick-moving drilling rigs in oilfields. Background technique: [0002] There are mainly two types of fast-moving drilling rigs used in oil fields, one is vehicle-mounted and the other is trailer-mounted. It is characterized in that it can be driven on the road as a whole or only decomposed into several parts, and it is easy to move and install. construction. However, the maximum drilling depth of these two drilling rigs is limited to 4,000 meters, and the hook load is within 225 tons. When this limit is exceeded, only medium and large drilling rigs are used. [0003] Medium and large drilling rigs are assembled in modules, and are divided into box-stack type and rotary-lift type due to different driving types. Their components include derrick, base, base accessories and various operating equipment placed on the base. The difference between the two lies in the structure of the base. The base of the box-sta...
