Abstract

The invention relates to a direct-reading examining seal instrument suitable for an eccentric water distributor. The direct-reading examining seal instrument comprises an examining seal instrument framework, a control part, a direct-reading pressure measurement part, a controllable sealing pup joint and a controllable positioning pup joint, wherein the control part, the direct-reading pressure measurement part, the controllable sealing pup joint and the controllable positioning pup joint are sequentially arranged on the examining seal instrument framework from top to bottom; and the control part is connected with the controllable sealing pup joint and the controllable positioning pup joint respectively and drives the controllable sealing pup joint and the controllable positioning pup joint to work. According to the direct-reading examining seal instrument suitable for the eccentric water distributor, the real-time monitoring on examining seal data can be realized, and the operations of controlling of the opening and the closing of a positioning arm and the setting and the unsetting of a seal section are realized by a motor through an upper computer software control instrument.

Description

technical field [0001] The invention belongs to the field of seal inspection and testing applied to layered water injection wells, and relates to a device for inspecting the sealing effect of a packer for layered water injection wells, in particular to a direct-reading seal inspection instrument suitable for eccentric water distributors. Background technique [0002] Sealing test is an important part of the well testing work of layered water injection wells. At present, the commonly used seal test method is the traditional mechanical seal section with a storage seal test gauge for seal test. During the test, it must be seated with the impact of a heavier weighted rod, and the seat seal and unsealing are not reliable. The positioning arm is prone to false triggering and some layers cannot be measured. Because the storage type seal inspection pressure gauge is used, the seal inspection effect can only be judged by playing back the data after the instrument is taken out. If i...
