The invention relates to the technical field of tubing plugs, in particular to a blanking plug for eccentric water distributor, comprising a support block positioning device, a plugging device for the eccentric water distributor, a centre pole and a positioning head, wherein a left support block and a right support block which can extend outside to tightly clamp the inner wall of a tubular column are installed on the support block positioning device; the plugging device for the eccentric water distributor, which is capable of plugging the inner chamber of a working barrel of the eccentric water distributor, is fixedly installed at the upper part of the support block positioning device; the centre pole is fixedly installed at the upper part of the plugging device for the eccentric water distributor; and the positioning head capable of being clamped at the upper end of the inner chamber of the working barrel of the eccentric water distributor is fixedly installed at the upper end of the centre pole. The blanking plug has reasonable and compact structure, achieves convenient use and can be fixed in the working barrel of the eccentric water distributor through the left support block, the right support block and the upper positioning head; and the blanking plug seals the inner chamber of the working barrel of the eccentric water distributor by reasonably setting the installation position of a sealant barrel, and is characterized by simple structure, low cost, safety, reliability, simplicity and high efficiency.
Description
technical field [0001] The invention relates to the technical field of oil pipe plugs, and relates to an eccentric water distributor plug. Background technique [0002] The oil pipe plugging technology is the guarantee to realize the safe snubbing operation of oil, water and gas wells, and it is also the bottleneck restricting the popularization and application of snubbing operation technology. At present, the structure of the well string is an eccentric water distributor plus a packer for water well under pressure operation. At home and abroad, the internal sealing of the string is generally realized by the tubing plug, which has the following disadvantages in the actual use process: complex structure, high cost, Inconvenient to use and poor safety performance. Contents of the invention [0003] The invention provides an eccentric water distributor plug, which overcomes the above-mentioned deficiencies in the prior art, and can effectively solve the problems of the exist...
