Abstract

The invention provides a combined integrated oilfield packer, and relates to the technical field of oil and gas development. The combined integrated oilfield packer comprises a supporting assembly, a setting mechanism and an unsealing mechanism, wherein the supporting assembly comprises a central pipe, joints, a connecting ring, an adjusting cylinder, a first through hole and second through holes; the top end and the bottom end of the central pipe are fixedly connected with the joints; the outer side of the middle of the central pipe is fixedly connected with the adjusting cylinder; the second through holes are formed in the left side and the right side of the lower portion of the central pipe; the setting mechanism is matched with a centering mechanism and a rotating assembly to perform setting on the packer; and the unsealing mechanism is used for unsealing the packer. Oil liquid is injected into the central pipe, so that the oil liquid is pressed into the centering mechanism through the first through hole, and the centering mechanism is used for centering the packer; and meanwhile, the rotating assembly and the supporting assembly are matched with the centering mechanism to enable the setting mechanism to work, so that setting is completed, and the packer is convenient to center and set.

Description

technical field [0001] The invention relates to the technical field of oil and gas development, in particular to a combined integrated oil field packer. Background technique [0002] The oilfield packer is a downhole tool. In order to realize the separate production and injection of the oilfield, it is necessary to separate each oil layer through this downhole tool. [0003] When the oilfield packer is running in the well, it is easy to have an inclination angle with the casing in the well, which will have an adverse effect on the setting operation, and the packer needs to be righted. However, the current oilfield packer righting and setting operations are cumbersome. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the invention provides a combined integrated oilfield packer, which solves the problem of difficulty in righting and setting the packer. [0005] In order to achieve the above objectives, the present invention is achieved through...
