Description
Technical Field
The invention relates to the technical field of shale gas exploitation, in particular to a pipe column bidirectional coupling integrated self-adaptive floating slip.
Background
In recent years, the exploration reserve of the shale gas in China is increased rapidly, and the exploitation technology of the shale gas is also remarkably improved. The key technology is to control the pressure in the oil pipe and the annular space of the oil sleeve and overcome the upper jacking force of the pipe column. In order to overcome the jacking force of the pipe string, a fixed slip and a moving slip are generally adopted to alternatively clamp the pipe string. The fixed slips are simple in structure and mature in technology. The moving slips technology has short development time and relatively imperfect technology.
In the process of lifting and lowering the pipe column, the stress of the pipe column is upward when the annular pressure is higher, and the stress of the pipe column is downward when the annular pressure is lower. The traveling slips must therefore be satisfied to prevent the string from jacking up and dropping down. In the past, two independent slip devices are usually adopted to limit two directions of a tubular column respectively, so that a moving slip group is complex in structure and complex in operation, and misoperation can occur to cause incorrect limitation of the direction of the tubular column. Therefore, how to develop a traveling slip which can prevent the pipe string from flying out and can also prevent the pipe string from falling into a whole, thereby reducing the operation difficulty and reducing the occurrence of accidents is a technical problem which needs to be solved urgently.

if the pipe string moves downwards relative to the bidirectional floating slips, the upper slip seat a14a and the upper slip seat b14b are driven to move downwards, meanwhile, the lower slip seat c14c and the lower slip seat d14d are driven to move upwards under the action of the connecting rod, the upper slip seat a14a and the upper slip seat b14b are of an inverted hammer-shaped structure, the lower slip seat c14c and the lower slip seat d14d are of a conical structure, and further the upper slip a13a, the upper slip b13b, the lower slip c13c and the lower slip d13b are radial, the clamping force of the pipe string is increased, and the downward movement of the pipe string is overcome;
if the pipe string moves upwards relative to the bidirectional floating slips, the pipe string drives the lower slip seat c14c and the lower slip seat d14d to move upwards, and simultaneously drives the upper slip seat a14a and the upper slip seat b14b to move downwards under the action of the connecting rod, the upper slip seat a14a and the upper slip seat b14b are of inverted hammer-shaped structures, and the lower slip seat c14c and the lower slip seat d14d are of conical structures, so that the upper slip seat a13a, the upper slip seat b13b, the lower slip seat c13c and the lower slip seat d13b are radial, the clamping force on the pipe string is increased, and the downward movement of the pipe string is overcome;
when the pipe string is not required to be held, the piston rod of the hydraulic cylinder 7 is recovered, so that the upper slip a13a, the upper slip b13b, the lower slip c13c and the lower slip d13b are radially expanded, and the holding effect on the pipe string is released.
