Description
Technical field
The utility model is related to a kind of hanger and oil pipe positioner, the logging assembly using the hanger.
Background technology
At present, in oil extraction process, downhole flow, pressure recovery in order to understand oil well, gas well and water injection well etc.
Situation, often timing, depthkeeping degree be tested hole condition, to know oil well, gas well and the downhole conditions of water injection well.Tradition
Downhole testing mode be to use steel wire hang tester, the setting that tester is transferred into underground by steel wire rope is deep
Spend at position, to be tested by tester downhole conditions, but this method of testing has following defect：
1, test the time of a bite well（The time that mainly down-hole pressure recovers）One to two months are needed, in this period
Interior, the medium of underground can produce erosion to steel wire rope, and the erosion condition is extremely serious in the later stage so that steel wire rope is often broken
And cause tester to drop to shaft bottom, trigger well logging accident and economic loss；
2, the well of oil well, gas well and water injection well is very deep, and the corresponding steel wire rope needed for well logging is generally required
Thousands of rice, the steel wire rope cost needed for causing well logging is higher, and will be corroded after using five to six times per spooling
It can not use, so as to increase the cost of logging steel wire rope；
3, in well logging, need personnel prolonged during testing to the oil well in test, gas well and water injection well
It is on duty, it will so cause the significant wastage of human and material resources and financial resources.
The U of Chinese patent literature CN 202325475 disclose a kind of Bidirectional positioning hanger, including release part and outstanding
Hanging device part is constituted.Hanger part is provided with that can carry out the hitch of uplink and downlink Bidirectional locking, and hitch is main
The upper and lower roller support arm being hinged by pull bar and thereon is constituted, and under being pulled in pull bar, upper and lower roller support arm is flared out and locked
It is scheduled on tubing wall；The bottom connection logging instrument of hanger part, top are provided with the pull bar upper end for being threaded in hitch
Fishing head.Release part, which is provided with, to be used to snap connection the switch hook on fishing head during going into the well, with this pair
After being transferred to hanger for locating to setting well depth position, by the case of the winch brake of ground, above proposing rear release suddenly
Steel wire rope, realizes that switch hook discharges from fishing head, while the hitch of hanger part opens and realizes locking so that outstanding
Hanging device part is in the state of logging instrument is hung on hanger tubing wall.But the Bidirectional positioning hanger is being salvaged from oil well
During hanger part, in the case of being hampered in hanger part, the hitch of hanger part will be unable to unblock and in oil pipe
Interior movement, so not only causes hanger part can not be salvaged from oil well and comes, and the fishing head of hanger part will be with
Fishing tool is stuck, causes fishing tool can not all be pulled out together with hanger part.Such as by increasing steel on fishing tool
If the trial unfreezing of the drag force of cord, easily there is the phenomenon broken in the steel wire rope connected on fishing tool, is applied to salvaging
Bring great potential safety hazard in work scene.Thus existing hanger exists and itself can not pulled out after being hampered and related salvaging work
The problem of tool can not be pulled out together.
