Description
Technical field
The utility model belongs to fish fishing operation field, and in particular to a kind of continuous pipe salvaging flow controller lead stamp.
Background technique
At present in the problem flow controller complex process operation of underground, continuous pipe sleeve mills/bores grinding process and continuous pipe salvages work
The combined application of skill is more and more common, although fish head shape and diameter can play lead stamp judgement by conventional, due to continuous pipe
The factors such as flexible and casing programme influence, and now can not pass through ground depth metering device accurate judgement during modifying fish head
Effective salvaging length of fish head, and then can not be provided to subsequent fishing and reliably enter fish depth parameter, cause set milling/brill
After mill, the phenomenon that can not grabbing fish head is repeatedly salvaged, construction speed is seriously affected.
According to investigation, existing several conventional lead stamps are mainly hit the striking mark formed at the top of fish head by lead stamp and are sentenced
Disconnected fish head form, but the relevant parameter for effectively salvaging length cannot be obtained, continuous pipe sleeve milling/brill mill length cannot pass through ground in addition
Face depth registration system accurately controls, and therefore, causing later period fishing fish head can not grab, need to by repeatedly lower lead stamp,
Lower fishing tool makes repeated attempts, and does not salvage the lead stamp of length effectively for lower continuous pipe inquisition topic flow controller fish head.
Utility model content
The purpose of this utility model is to provide a kind of continuous pipes to salvage flow controller lead stamp, overcomes existing for existing lead stamp
Technical problem.
The technical scheme that the utility model is provided is as follows:
A kind of continuous pipe salvaging flow controller lead stamp, including upper casing interconnected and lower piece housing, the upper section
Shell is equipped with multiple hydrophthalmias, and top connection is equipped in the upper casing, guiding set and lead, institute are equipped in the lower piece housing

Guiding 7 outer diameter Ф 65mm, internal diameter 45mm of set can connect slightly larger than the flow controller fish head 12 that outer diameter is 38mm in lead 6
Guide function is played before touching flow controller fish head 12, entering deep (covering 7 bottoms from 6 bottom of lead to guiding) is 60mm, is had with fishing tool
Shortest length needed for effect crawl flow controller fish head 12 matches.It can protect lead 6 during up and down simultaneously.
Embodiment 4:
A kind of method that can judgement flow controller be salvaged is present embodiments provided, salvages flow controller lead stamp using continuous pipe
11 and continuous pipe 9 cooperate, by external slips connector 10 by continuous pipe salvage flow controller lead stamp 11 top connection 3 and continuous pipe
9 connections (as shown in Figure 2) by the decentralization of continuous pipe 9 and are gone up, and observe and rise on continuous pipe 9 under pump note flushing operating condition
Afterwards, whether there is the mark of flow controller fish head 12 on lead 6；
If there is the mark of flow controller fish head 12 on lead 6, illustrate that 12 form of flow controller fish head is proved to be successful, and enter
Fish depth has reached guiding set 7 and has entered depth, and the later period can pass through the real-time fishing of fishing tool；If without flow controller fish on lead 6
First 12 mark then illustrates 12 form authentication failed of flow controller fish head, while judging to be unsatisfactory for fishing tool into fish depth to having
Effect salvages the requirement of length, and the later period can not implement fishing by fishing tool.
This method is applied to 9 sets of millings of continuous pipe/brill and grinds problem flow controller, after modifying fish head, even if can not accurately show
In the case of, it is verified while to fish head shape and effective salvaging length, the salvaging for problem flow controller provides reliable basis.
Embodiment 5:
On the basis of embodiment 4, a kind of method that can judgement flow controller be salvaged is present embodiments provided, pump note rinses
Operating condition detailed process are as follows: base fluid is pumped into continuous pipe 9 with 100L/min discharge capacity, circulation is kept, base fluid is made to pass sequentially through salvaging
Duct 4 and hydrophthalmia 5, the annular space between continuous pipe 9 and pit shaft 8 rinse pit shaft 8 and are located at continuous pipe salvaging flow controller use
The part below of lead stamp 11, while the continuous pipe of tripping in salvages flow controller lead stamp 11 at the uniform velocity into pit shaft 8 with 15m/min；
When continuous pipe salvage flow controller with lead stamp 11 down toward 12 or more 500m of flow controller fish head when, continuation arranged with 100L/min
It measures and is pumped into base fluid into continuous pipe 9, keep circulation, while reducing speed to 10m/min, continue the continuous pipe of tripping in and salvage flow controller
With lead stamp 11；When continuous pipe salvage flow controller with lead stamp 11 down toward 12 or more 200m of flow controller fish head when, increase discharge capacity to 150L/
Min, base fluid, which passes sequentially through, at this time salvages duct 4 and hydrophthalmia 5, high speed liquid flow is sprayed with oblique lower angle, by flow controller fish head 12
Overburden object is rinsed well, while reducing running speed to 2m/min, until being hampered in 12 position of flow controller fish head；
Base fluid is pumped into continuous pipe 9 with 150L/min discharge capacity after being hampered and keeps circulation, to play continuous pipe 9 on 2m/min,
When continuous pipe, which salvages flow controller, to be risen with lead stamp to 12 or more 200m of flow controller fish head, reduce discharge capacity to 100L/min, while with
10m/min continues to have gone up continuous pipe 9；When continuous pipe, which salvages flow controller lead stamp 11, to be risen to 12 or more 500m of flow controller fish head,
Speed is played in increase to 15m/min；When continuous pipe 9 rises to well head, stop pump note, speed is played in reduction to 0.5m/min, it will
Continuous pipe salvage flow controller with lead stamp 11 from pit shaft 8 out.
During 9 tripping in of continuous pipe, it is hampered in 12 position of flow controller fish head, illustrates that continuous pipe salvages flow controller lead stamp
Flow controller fish head 12 is struck.After the continuous pipe 9 of each tripping in, it can only be hit once with top of fish, otherwise be unable to judge accurately fish
The form of head.After having gone up continuous pipe 9, replaceable lead 6 or reams im-pression portion and can be used next time.
It is recycled by 150L/min huge discharge, is hampered during preventing continuous pipe from salvaging 11 tripping in of flow controller lead stamp, and
It passes sequentially through and salvages duct 4 and hydrophthalmia 5, with 45oOblique lower angle sprays high speed liquid flow, by 12 overburden object of flow controller fish head
It rinses well.
During continuous pipe 9 is transferred and gone up, continuous pipe salvages flow controller lead stamp 11 and external slips connector 10 is anticipated
Outer disengagement falls well, using milling cone, is salvaged by salvaging duct 4.
Exemplified as above is only to the utility model for example, not constituting to the protection scope of the utility model
Limitation, it is all to be belonged within the protection scope of the utility model with the same or similar design of the utility model.Embodiment does not have
There are the well-known components and common structure or conventional means of the component described in detail and the structure category industry, does not describe one by one here.
