Description
Technical Field
The invention relates to the technical field of deep sea oil and gas well engineering, in particular to a tool for fixing a surface layer conduit by vibration after the surface layer conduit is arranged by a jet method and a test device thereof.
Background
In the oil and gas drilling industry of ocean engineering, the technology of jetting and setting surface layer guide pipes is widely applied because the time of drilling operation can be saved and the effects of reducing the risk and the cost of drilling can be achieved. The injection method is characterized in that a drill bit and a slurry motor are put into a special tool through a surface layer conduit to form an injection running pipe string together with the surface layer conduit, wherein the drill bit mainly has the function of crushing soil in front of a conduit shoe, then slurry is pumped into the conduit through a drill column to carry rock debris out of a well bottom from the inner wall of the surface layer conduit and an annular space of the drill column and then directly discharged into a seabed, and then the surface layer conduit is put into the designed depth.
The surface guide pipe is a first layer of pipe column installed in deepwater drilling, the upper part supports an underwater blowout preventer group (drilling stage) and an underwater Christmas tree (production stage), and the lower part suspends various layers of casing strings and is an important holding structure. The bearing capacity of the surface layer guide pipe changes due to soil body disturbance, and if the surface layer guide pipe sinks and inclines after the jet installation is in place, great difficulty is brought to operations such as later-stage lowering of the pipe column, connection of an underwater blowout preventer and installation of an underwater Christmas tree, the operation efficiency is influenced, and even wellhead scrapping is caused. Therefore, after the surface guide pipe is lowered into a designated position, certain 'waiting time' is needed, cementing stress is built between the surface guide pipe and seabed soil, and the surface guide pipe is reinforced along with the increase of time, so that the surface guide pipe can bear loads such as blowout preventer (or Christmas tree) gravity in the vertical direction, casing string gravity and the like, and can not incline under the action of seabed transverse wave force and transverse counter force at the end part of the blowout preventer stack. Therefore, a vibration solid surface layer conduit tool is needed, which can improve the fluidity of soil through vibration, further shorten the waiting time and further reduce the deep sea drilling cost; on the other hand improves the homogeneity of earth through the vibration, and then improves cementation intensity and quality between top layer pipe and the seabed stratum earth, improves top layer pipe bearing capacity.
