[0002] With the increasing strict requirements of oil companies for the convenience and automation of drilling contractors, more and more drilling service providers require rapid installation and transportation of equipment. And due to the high cost of renting cranes abroad, more and more drilling service providers require crane-free installation at the beginning of the tender. However, the existing base structure has the following problems:

[0003] 1. There are four inclined columns around, which need to be assisted by a crane for installation after the top layer of the base is lifted, which is time-consuming and laborious;

[0004] 2. The rear side of the middle column is a single-column structure, mainly bearing the load of the turntable, with poor stability;

[0005] 3. There are many transportation modules, and the disassembly and assembly process wastes time. Content of the Utility Model

[0006] In view of the above problems, the utility model provides a new base of an oil drilling and workover rig, which solves the problems in the background art.

[0007] The technical solution adopted by the utility model to solve its technical problems is: a new base of an oil drilling and workover rig, including a top layer and a bottom layer. Support components are hinged on both sides of the top layer and the bottom layer. The support components successively include a front support member, a middle support member and a rear support member. The front support member and the rear support member have the same structure and are both in an inverted triangular structure. A fixed rod adjacent to and on the same axis as the front support member is also provided on the bottom layer. When the front support member is inclined, the fixed rod supports the front support member. A connecting member is provided between the front support member and the fixed rod. The middle support member includes an inclined column. One end of the inclined column is hinged to the top layer and is adjacent to the intersection point of the front support member and the top layer, and the other end is provided with a pulley. A chute cooperating with the pulley is provided on the bottom layer. A fixing member for fixedly connecting with the middle support member is provided at one end of the chute close to the rear support member.

[0022] Working principle: A new base for an oil drilling and workover rig provided by the present utility model, when in use:

[0023] Lifting condition: According to Figure 1The shown transportation state diagram transports the base body to the well site. The wellbore center is aligned and lands on the ground. After the main locomotive with the derrick is installed in place, the connecting pin 11 is removed. Use a 5t small winch to install the hoisting main rope 9 and at the same time hang it on the traveling hook 8. The traveling hook 8 rises and slowly pulls up the top layer 1. When the top layer 1 is hoisted, the front side support member 3, the middle support member, and the rear side support member 5 rise along with it. At the same time, the pulley 7 rolls on the chute of the bottom layer 2. Until the whole is hoisted in place, insert the pin shaft 10. When the base body is hoisted in place, use a 5t small winch to install the outer ladder 6 of the base, the escape slide, the ramp, the railing, etc. in place, and then the base can carry out drilling operations.

[0024] Lowering condition: Opposite to the hoisting condition. First, use a 5t small winch to remove the components such as the outer ladder 6 of the base, the escape slide, the ramp, the railing, etc. Then use a 5t small winch to install the hoisting main rope 9 and at the same time hang it on the traveling hook 8. The traveling hook 8 first slowly rises to slightly pre-tighten the hoisting main rope 9, and then remove the pin shaft 10. At this time, slowly lower the traveling hook 8, and rely on the self-weight of the top layer 1 to slowly lower the top layer 1 of the base. The front side support member 3, the middle support member, and the rear side support member 5 move along with it. After lowering to the lowest position, insert the connecting pin 11. After the base is lowered, the base body can be transported to the next well site.
