Embodiment 1

[0034] Such as figure 1 The drill floor ramp structure shown to facilitate the assembly of drilling tools includes a ramp 1 for connecting the drill floor 3 and the site, a material preparation area 2 located on the site and facing the ramp 1, and the drill floor 3 is provided with a slope The baffles 5 on both sides of the road 1, the pneumatic winches 4 are arranged at the baffles 5 on one side or both sides, the first groove 6 is set on the center line of the ramp 1, the second groove 7 is set on the material preparation area 2, and the drill floor The third groove 8 is provided on the 3, and the major axes of the first groove 6, the second groove 7 and the third groove 8 are coplanar; several axis-level rollers 9 are arranged in the first groove 6 along the major axis direction The supporting assembly and the lifting device 10 for driving the lifting of the supporting assembly are arranged in the second groove 7; the fixed pulley 11 is arranged in the third groove 8, and t...

Embodiment 2

[0043] On the basis of Example 1, such as figure 2 As shown, the structure of the supporting assembly is as follows: it includes a number of U-shaped supporting blocks 12 evenly distributed along the long axis of the second groove 7 , and each U-shaped supporting block 12 is driven by a lifting device 10 to lift.

[0044] In this embodiment, the lifting of each U-shaped supporting block 12 is independent.

[0045] In the process of gradually lifting the drilling tool by several U-shaped supporting blocks 12, before the top of the drilling tool reaches the height of the drill floor, each U-shaped supporting block 12 moves from the side close to the drill floor to the side far away from the drill floor. The side and the height gradually decrease, so as to ensure that the drilling tool can enter the drill floor in an inclined posture, which is conducive to the upturning of the box end of the drilling tool to leave the ground, so that the traveling car elevator can directly buckl...

Embodiment 3

[0047] On the basis of Example 1, such as image 3As shown, the structure of the supporting assembly is as follows: a strip-shaped bearing plate is included, and the length direction of the bearing plate is parallel to the long axis of the second groove 7; the bearing plate includes an inclined portion 13 close to the ramp 1 direction, and a The horizontal part 14 in the 1 direction, the upper surface of the inclined part 13 is inclined from bottom to top from the end adjacent to the horizontal part 14 to the end far away from the horizontal part 14; the inclined part 13 is provided with a protrusion 15; the lifting device 10 drives the load The board as a whole is raised and lowered. A chute 16 is arranged on the horizontal part 14, the axis of the chute 16 is parallel to the long axis of the second groove 7, and a baffle 17 slidingly connected in the chute 16 is included, and the surface of the baffle 17 is perpendicular to the axis of the chute 16 ; The baffle 17 is driven...

Abstract

The invention discloses a drill floor ramp structure and a method for combining drilling tools which are convenient for combining drilling tools, including a ramp for connecting the drilling floor and the site, a material preparation area located on the site and facing the ramp, and a drill floor is provided with a ramp. The baffles located on both sides of the ramp, a pneumatic winch is set on the baffles on one or both sides, the first groove is set on the center line of the ramp, the second groove is set on the material preparation area, and the third groove is set on the drilling floor , the long axes of the first groove, the second groove and the third groove are coplanar; a number of rollers with horizontal axes are arranged in the first groove along the direction of the long axis; A lifting device used to drive the lifting and lowering of the bearing assembly; a fixed pulley is arranged in the third groove, and the axis of the fixed pulley is perpendicular to the long axis of the third groove; the first groove, the second groove and the third groove are matched with Removable cover. The invention is used to solve the problem that the combined drilling tool operation occupies the crane time in the prior art, and realizes the purpose of not occupying the well site crane when combining the drilling tools.

Description

technical field [0001] The invention relates to the field of petroleum and natural gas drilling, in particular to a ramp structure of a drill floor which is convenient for a combined drilling tool and a method for combining the drilling tool. Background technique [0002] In the field of oil and gas drilling, the bottom hole assembly (BHA) is a general term for drilling tools located at the bottom of the drilling string, generally including drill bits for rock breaking, motors for output power, drill collars for pressure, Centralizers for straightening and directional deflection, jars for improving safety, and even downhole tools such as MWD, LWD, and rotary steering. The so-called "assembly drilling tool" operation at the engineering site is the on-site connection of the bottom hole assembly before spud or when the drilling tool is pulled out to replace the drilling tool. When assembling drilling tools, it is necessary to lay the required drilling tools flat on the ground ...
