Description
Technical field
This utility model is related to oilfield, the detachable annular space log blowout hookup of specifically a kind of hydraulic drive.
Background technology
Usually, need to establish lubricator in well logging and carry out airtight well logging, but be frequently encountered in practical logging
Situations below: one be decentralized wellhead and oil pipe spacing too little it is impossible to install lubricator；Two is beam hanger for pumping machine and sucker rod
Fang Kazi can encounter lubricator in the running, and mechanical accident easily occurs；Three is that in lubricator, dead oil is excessive, and passage is too small, instrument
Device is unable to G.I.H；Four be oil well ring set space in oil-water interfaces near well head, open test strobe, profit enters anti-
After jet pipe, instrument cannot rely on own wt G.I.H；Five is after standpipe goes down, and instrument completes well logging and above carries to well head, and
Face the risk that cable is wound around tubing string, once being wound around, original unwrapping method all can not use, and can only cut off cable and be wound on
On well head, operation is waited to rise out.These be exactly annular space log faced " do not stand, under do not go, can't get out " a difficult problem, cause
Annular space log cannot realize airtight execution truly, and the well-log information so enrolled and actual production environment have one
Fixed difference, exploitation and understanding to oil field have a negative impact.
Content of the invention
In order to overcome the inaccurate deficiency of the well-log information being easily caused admission during existing annular space log, this utility model provides
A kind of detachable annular space log blowout hookup of hydraulic drive, this hydraulic drive detachable annular space log blowout hookup makes instrument
Can light G.I.H, solve the problems, such as that cable is wound around tubing string, it is possible to achieve completely airtight, so that it is guaranteed that well-log information
Accuracy.
The technical solution of the utility model is: a kind of detachable annular space log blowout hookup of hydraulic drive, including removable
Unload lubricator, described detachable blowout prevention bottom of the tube is connected on well head by snap joint, and detachable lubricator top is connected with
High-tension blowout-prevention box, high-tension blowout-prevention box is outside to connect high-pressure hose by high-voltage quick joint, and the other end of high-pressure hose connects electricity
Hydrodynamic press pump, described high-tension blowout-prevention cassette bottom portion connects instrument by piston instrument separator；Also include small-sized lubricator, and small-sized
Pressure release gate b is provided with lubricator.
This utility model has the advantages that due to taking such scheme, and this pressure advances detachable annular space log
Blowout hookup solve faced during annular space log " do not stand, under do not go, can't get out " a difficult problem, just do not affecting oil pumper
Often produce, instrument can light G.I.H, solve the problems, such as cable winding tubing string.Greatly improve the Sealed efficiency of annular space log,
Decrease the discharge of greenhouse gases and the waste of the energy, have great practical value.Improve annular space log pound sign utilization rate 10%
More than；Original annular space log Sealed efficiency is promoted to more than 95%, thus also lifts the accuracy rate of well-log information；Reduce well logging
The difficulty of construction, the level of security of lifting site operation.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of small-sized lubricator.
In figure 1- electric hydraulic pump, 2- high-tension blowout-prevention box, 3- high-voltage quick joint, the detachable lubricator of 4-, 5- piston instrument
Device separator, 6- snap joint, 7- pressure release gate a, 8- instrumented site detection valve, the small-sized lubricator of 9-, 10- pressure release gate b,
11- high-pressure hose.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings:
Shown in Fig. 1, Fig. 2, a kind of detachable annular space log blowout hookup of hydraulic drive, including detachable lubricator 4,
Described detachable lubricator 4 bottom is connected on well head by snap joint 6, and well head is provided with pressure release gate a7 and instrument position
Put detection valve 8, detachable lubricator 4 top is connected with high-tension blowout-prevention box 2, high-tension blowout-prevention box 2 is outside to pass through high-voltage quick joint 3
Connect high-pressure hose 11, the other end of high-pressure hose 11 connects electric hydraulic pump 1, and piston is passed through in described high-tension blowout-prevention box 2 bottom
Instrument separator 5 connects instrument.This blowout hookup also includes small-sized lubricator 9, and small-sized lubricator 9 height is 50cm, and small-sized
Pressure release gate b10 is provided with lubricator 9, small-sized lubricator 9 bottom can be connected with well head by snap joint 6, its top
It is again provided with high-voltage quick joint.
During well logging, instrument is connected under propelling piston by piston instrument separator 5, is placed into detachable blowout prevention
In pipe 4, then motor belt motor is moved electric hydraulic pump 1 and is operated, and the water under high pressure forming 10mpa, as power, promotes plunger and instrument string
Down to well head, then it is fixed on well head using seal approach.Now can dismantle detachable lubricator 4, change small-sized
Lubricator 9, connects instrument string with cable, then with water under high pressure, cable and instrument is depressed in well.Can solve in this way
Instrument in lubricator " under do not go " problem.Meanwhile, small-sized lubricator 9 can rotate with decentralized wellhead, is not pumped
Bar hanging rope etc. affects, so when instrument plays well head from shaft bottom, cable and be wound around during tubing string phenomenon it is also possible to utilize rotation well
The mode solution of mouth twines, and this solves " can't get out " this difficult problem again.Detachable lubricator 4 and small-sized lubricator 9 are pacified on well head
All it is attached using flange when dress, lubricator can be made more to be adjacent to well head, reduce the angle of inclination of lubricator, fit
For most of decentralized wellheads, substantially solve the difficult problem of " not standing ".
Hydraulic drive detachable annular space log blowout hookup it is achieved that production profile logging construction in do not put casing gas,
Safety is greatly improved it is achieved that annular space log zero-emission no pollution, has reached environmental protection pressure measurement requirement.This device can be real
Now completely airtight it is ensured that the concordance of well logging and oil well production environment, thus obtaining really and accurately production profile money
Material.Meanwhile, what this hydraulic drive detachable annular space log blowout hookup solved that conventional blowout hookup cannot overcome is three big
A difficult problem: do not affect oil pumper and normally produce, instrument can light G.I.H, solve the problems, such as that cable is wound around tubing string.Greatly carry
The high Sealed efficiency of annular space log, decreases the discharge of greenhouse gases and the waste of the energy, has great practical value.Improve
Annular space log pound sign utilization rate more than 10%；Original annular space log Sealed efficiency is promoted to more than 95%, thus also lifting well logging provides
The accuracy rate of material；Reduce the difficulty of well logging construction, the level of security of lifting site operation.
