Abstract

The invention provides a combined integrated oil field packer and relates to the technical field of oil and gas development. The combined integrated oilfield packer, the packer includes: a support assembly, the support assembly includes a central pipe, a joint, a connecting ring, an adjustment cylinder, a first through hole and a second through hole, the center pipe Both the top end and the bottom end are fixedly connected with joints, the outside of the middle part of the central tube is fixedly connected with an adjustment cylinder, and the left and right sides of the lower part of the central tube are provided with second through holes; the setting mechanism cooperates with the righting mechanism and the rotating assembly to set the packer; the unsealing mechanism is used for unsealing the packer. By injecting oil into the center pipe, the oil is pressed into the centralizing mechanism through the first through hole, and the centralizing mechanism straightens the packer. At the same time, the rotating component and the supporting component cooperate with the centralizing mechanism to make the setting mechanism work and complete the setting. The packer facilitates righting and setting.

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...
