Embodiment Construction

[0042] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific implementations disclosed below.

[0043] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected ...

Abstract

The invention discloses a multi-sealing, corrosion-resistant, leak-finding and plugging integrated oil production packer, which includes a central pipe, and further includes: a rubber sleeve, the rubber sleeve is set on the central pipe; slips, the slips are set on the central pipe Above; the first-stage propulsion unit, the first-stage propulsion unit is located at the first end of the rubber cartridge; the second-stage propulsion unit, the second-stage propulsion unit is located at the first end of the slip; The direction of travel of the units is the same. The beneficial effect of the invention is that the multi-stage isolation reduces the temperature difference inside and outside the packer, thereby reducing surface liquefaction and effectively preventing corrosion.

Description

technical field [0001] The invention relates to the improvement of a packer, in particular to a multi-seal, corrosion-resistant, leak-finding and plugging integrated oil recovery packer. Background technique [0002] The packer is used for delamination in oil production engineering. The packer is designed with an oil production channel. When setting, the piston sleeve goes up, and the oil production channel is opened; after setting, the pressure of the upper layer acts on the balance piston, pushing upward The rubber sleeve protects the unsealing pin from shearing force; when unsealing, the unsealing pin is sheared by the friction between the rubber sleeve and the casing, and the piston sleeve goes down to close the oil production channel. [0003] At present, the general packer has the following disadvantages: [0004] First, one-time isolation, insufficient sealing driving force, resulting in unsatisfactory isolation effect; [0005] Second, the driving force of the rubb...
