The invention relates to a packer, in particular to a universal packer for a through cable. The universal packer for the through cable comprises a packer main body, a through cable connecting joint and a cable connector, wherein the upper end of the packer main body is fixedly installed together with the lower end of the through cable connecting joint through screw threads, and the lower end of the packer main body is fixedly installed together with the upper end of the through cable connecting joint through screw threads; and the upper end of the through cable connecting joint, which is positioned on the upper part of the packer main body, is fixedly installed together with the lower end of the cable connector, and the lower end of the through cable connecting joint, which is positioned on the lower part of the packer main body, is fixedly installed together with the upper end of the cable connector. The universal packer for the through cable has the advantages of reasonable and compact structure and convenient use, and can fix the cable through the through cable connecting joint and the cable connector so as to connect the cable together with a downhole direct reading instrumentto fast transmit data in the downhole direct reading instrument, thereby having the advantages of safety, reliability, simplicity, convenience and high efficiency.
Description
technical field [0001] The invention relates to a packer, which is a universal packer for cables. Background technique [0002] In the process of well logging, well testing, perforation joint testing, formation testing, etc., it is used to test together with the packer. The signal sent by the direct reading instrument in the downhole is transmitted through the cable, and the test is performed under the packer. When the cable of the direct reading instrument has to pass through the packer, the domestic and foreign joint test uses a single special tool and a special cable packer. It is used in the test occasions of different packers, and the use cost is relatively high. Contents of the invention [0003] The present invention provides a cable-passing universal packer, which overcomes the deficiencies of the prior art above, and can effectively solve the cost caused by the need to use a single special-purpose tool and a dedicated cable-passing packer in joint testing. High ...
