Embodiment Construction

[0023] The present disclosure will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific implementation manners described here are only used to explain relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only parts related to the present disclosure are shown in the drawings.

[0024] It should be noted that, in the case of no conflict, the implementation modes and the features in the implementation modes in the present disclosure can be combined with each other. The present disclosure will be described in detail below with reference to the drawings and embodiments.

[0025] Such as figure 1 As shown, the double-seal multi-action packer is configured on the outer surface of the tubular member and the inner surface of the borehole (ie figure 1 In the annular space defined by the wall shown in ), the packer includes a control part, a driving p...

Abstract

The present disclosure provides a double-seal multi-function packer. The packer is arranged in the annular space defined by the outer surface of the tubular member and the inner surface of the borehole. The packer includes a control part, a driving part, an arm, a packing The base of the packer, the pressure-sensitive layer and the pressure sensor; the arm, the base of the packer, and the pressure-sensitive layer are sequentially arranged along the radial direction of the packer from inside to outside; the outer end of the arm is connected to the base of the packer, and the pressure sensor is embedded in the pressure sensor. Inside the sensitive layer, the pressure sensor is used to sense the pressure change in the pressure sensitive layer; the control part is electrically connected to the pressure sensor, and the control part is electrically connected to the drive part; the control part controls the drive part to operate according to the pressure sensed by the pressure sensor , so that the packer seals the annular space.

Description

technical field [0001] The present disclosure relates to a packer, in particular to a double-seal multi-function packer. Background technique [0002] The packer in the prior art, for example, adopts a material that can swell when encountering oil, and is filled between the inner body and the outer boundary, such as an annular packer, which can basically maintain the distance relative to the inner surface of the borehole (that is, the aforementioned outer boundary). Simultaneously with the axial position, it can move sealingly relative to the tubular member (ie the aforementioned inner body). [0003] However, this kind of packer is difficult to deal with when the packer is used up, for example, when the swelling material swells with oil. Contents of the invention [0004] In order to solve the above technical problems, the present disclosure provides a double-seal multi-action packer with a new sealing structure. The double-seal multi-function packer of the present disc...
