Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing.

[0024] figure 1 An open hole packer test rig 30 according to the present invention is schematically shown. The open-hole packer test device 30 includes a casing 5 , an open-hole packer 6 is arranged inside the casing 5 , and a simulated wellbore 7 is arranged in a gap between the casing 5 and the open-hole packer 6 . A first wellbore head 1 and a second wellbore head 10 are respectively arranged at two ends of the casing 5 to seal the inside of the casing 5 . The two ends of the open hole packer 6 are respectively provided with open hole packer heads, such as figure 1 The first open hole packer head 3 and the second open hole packer head 8. The open hole packer heads 3 , 8 are in sealing contact with the corresponding wellbore heads 1 , 10 , thereby forming the first annulus 4 and the second annulus 14 . The structure of the open hole packer 6 is well known to those ski...

Abstract

The invention relates to an open hole packer tester. The open hole packer tester comprises a sleeve; two end parts of the sleeve are respectively provided with a borehole gland in sealed connection with the sleeve; a first borehole gland is provided with a first pressurizing nozzle; an open hole packer is arranged in the sleeve; the end part of the open hole packer is provided with an open hole packer gland; a first open hole packer gland and a second open hole packer gland are in sealed connection with the open hole packer and corresponding borehole glands respectively to form a first annulus and a second annulus on the two end parts of the sleeve; the first pressurizing nozzle penetrates through the first borehole gland and is communicated with the first annulus; the second open hole packer gland is provided with a second pressurizing nozzle communicated with the open hole packer; a simulated borehole is arranged between the open hole packer and the sleeve. The sealing property of the open hole packer can be tested on the ground by the open hole packer tester, the cost is low, and the operation is simple.

Description

technical field [0001] The invention relates to a well completion equipment test device, in particular to an open hole packer test device. The invention also relates to a method for using the open hole packer test device. Background technique [0002] Horizontal well staged fracturing open hole packer completion technology is a new type of well completion technology in the field of oil and gas well engineering technology in recent years. It is mainly used in the fracturing stimulation of directional wells and horizontal wells in the exploitation of unconventional oil and gas resources. . When using this technology, the open hole packer can be used to divide the horizontal well into several sections according to the geological conditions of the formation and the needs of reservoir development, so as to realize layered operations, and perform staged fracturing on the production layer in a targeted manner. The oil drainage area of ​​the oil and gas production layer improves o...
