Abstract
The invention belongs to oil-gas mining technical fields, and the Refloatation method of stuck flow controller is buried more particularly to a kind of fracturing sand.Include the following steps, progress drifting first judges flow controller depth；Then it descends lead stamp tool string to combine, judges fracturing sand situation；Next replacement fishing sand tool string combination carries out fishing sand operation, and until fishing sand is completed, lead stamp is judged as flow controller fishing neck；Finally decentralization fishing socket tool string combination, crawl flow controller constantly above propose jarring, salvage until completing flow controller.To make underground whether belong to fracturing sand burial judge it is simpler accurately, more efficient to the salvaging of fracturing sand, the salvaging for burying stuck flow controller for fracturing sand is more efficient.
Description
Technical field
The invention belongs to oil-gas mining technical fields, and the salvaging side of stuck flow controller is buried more particularly to a kind of fracturing sand
Method.
Background technique
At present in the problem flow controller complex process operation of underground, stuck flow controller is buried for fracturing sand in the prior art
Refloatation method, disclose less, only retrieve, there is disclosure, continuous oil on the 8th Ningxia Young Scientist Forum collected works
Manifold technology refers in salvaging the exploration application on flow controller, encounter gas well shake out flow controller buried by fracturing sand when, can be with
Sediment outflow is carried out in such a way that well head is set a raft going, however this discharging modes are only able to satisfy gas well flow controller reference performance
Under sand discharge, the case where and its emission effect is also unsatisfactory, or Gas well blocking cementing for that fracturing sand, is but
It is unable to satisfy requirement.
Summary of the invention
The present invention provides the Refloatation methods that a kind of fracturing sand buries stuck flow controller.
Specific technical solution is that the fracturing sand buries the Refloatation method of stuck flow controller, is included the following steps, (1) is logical
Well, decentralization drifting tool string combination, wire rope socket+rotary joint+weighted lever+universal joint+bumper jar+gauguste cutter complete drifting,
Judge flow controller depth；(2) lead stamp tool string combines under, wire rope socket+rotary joint+weighted lever+universal joint+bumper jar+lead
Print, lead stamp judgment result displays have fracturing sand trace；(3) lead stamp tool string combination out, replacement fishing sand tool string combination, steel wire are played
Rope socket+weighted lever+universal joint+bumper jar+bailers carries out fishing sand operation, and until fishing sand is completed, lead stamp is judged as that flow controller is beaten
Fish out neck；(4) combination of decentralization fishing socket tool string, wire rope socket+rotary joint+weighted lever+universal joint+bumper jar+fishing socket are grabbed
It takes flow controller constantly above to propose jarring, is salvaged until completing flow controller.
Further, if fishing sand is completed in step (3), but flow controller can not be still grabbed, transfers lead stamp tool
String combination, wire rope socket+rotary joint+weighted lever+universal joint+bumper jar+lead stamp, lead stamp judgment result displays have a little throttling
Device center-pole, but there is still gravel traces, transfer the combination of crocodile clip tool string, wire rope socket+rotary joint+weighted lever+universal
Section+bumper jar+crocodile clip removes the cementing fracturing sand in fish head position, again repeatedly step (3).
Further, decentralization fishing socket tool string combination, wire rope socket+rotary joint+weighted lever+universal joint+bumper jar+
Fishing socket, grabs flow controller, and upward jarring is unable to complete flow controller unfreezing and above mentions, then cuts fishing socket pin, replace blind hammer
Tool string combination, wire rope socket+weighted lever+universal joint+bumper jar+blind hammer, downward jarring flow controller, until flow controller downlink,
Step (4) are repeated again until flow controller salvages completion.
Further, bumper jar is spring bumper jar.
Whether the present invention completes stuck to underground throttle device to be that fracturing sand buries progress accurate judgement by lead stamp determining method,
Then make the judgement for whether thering is fracturing sand to bury more accurate by the combination of special fishing tool string, the salvaging of fracturing sand
More efficiently；And it is further, judged by lead stamp determining method with the presence or absence of the cementing situation of fracturing sand, and pass through
Tool string combination is significantly more efficient to solve fracturing sand cementing the technical issues of causing flow controller that can not salvage, and covers fracturing sand
Bury the salvaging more convenient and efficient of stuck flow controller.
Specific technical solution
Embodiment 1 is completed flow controller in Soviet Union's 36-11-16H well and is salvaged.Soviet Union's 36-11-16H well construction relevant parameter, such as
Under, well type-diameter；Flow controller model-CQXD-71 to be salvaged；Gas production tree type-standard christmas tree salvages depth 1497m, oil
Pipe specification 3 1/2, casing pressure 3.44MPa.
Pump type bailers is a kind of pump-type tool, routinely lift pump and piston principle；It is set when sand is deposited on underground
Standby top, prevents when being normally carried out of salvaging, and lower bailers clears up fracturing sand.
When work, connector is above put on, piston rod, the piston being attached thereto move upwards together, and steel ball moves upwards at this time,
Sand in well is pumped；Top connection is transferred, steel ball drop is located in an eyelet, and the sand pumped is blocked by steel ball, is retained
In cylinder, extraction reciprocal in this way acts tool until rock sand is filled in cylinder.It is provided by supplier in the market.Such as treasured
The pump type bailers of Ji Jinhui petroleum machinery Co., Ltd production.
On October 18th, 2013 launches successfully: to after 1700 meters, decentralization flow controller to 850 meters of place's chance decks is sealed for drifting,
The flow controller for meeting deck envelope is salvaged afterwards and launches 1 new flow controller again to 1500 meters；On January 23rd, 2018 is caught at 1496 meters
It mentions motionless on flow controller, successively replaces pin three times, because jarring is multiple, pin is disconnected, salvages failure.
On July 12nd, 2018 flow controller in Soviet Union's 36-11-16H well is salvaged using technical solution of the present invention.
