Abstract
The invention discloses a continuous circulation device and method for operation of assembling a casing pipe. The device comprises a clamping system and a pouring and circulation system, wherein the clamping system is used for clamping the casing pipe to be assembled and controlling the lifting up and putting down of the whole set of device, a push-up force generated in the pouring and circulation process can be offset by gravity of a casing pipe column; the pouring and circulation system is used for pouring and circulating mud in the assembly process of the casing pipe. During continuous circulation, the casing pipe is filled with mud, pressure is increased, and a seal cup of the pouring and circulation system seals a set packer; mud pumped from a core pipe into the casing pipe reaches a shaft bottom and then upwards returns from an annular space between the outer part of a casing pipe wall and the inner part of a shaft, and the device starts mud circulating operation. The continuous circulation device has a reasonable and compact structure and has strong operability in use. During the operation of assembling the casing pipe, the device can prevent the casing pipe from being stuck, reduces shrinkage and collapse of a shaft wall, and can ensure the successful assembly of the casing pipe, so that the production cost is reduced.
