Description
Technical field
The down-hole flow channel switch instrument of the auxiliary oil recovery that the utility model adopts intelligent well completion mode to enter at present after relating to a kind of petroleum drilling completion in underground operation tool field.
Background technology
Intelligent well completion is oil exploitation technology more advanced in the world at present, is monitoring down-hole real time data, to understand each section of down-hole exploitation situation with main purpose, and close some extraction layer position as required, to control bottom water coning, extend the horizontal well life-span, increase the total oil production of individual well.This technique after brill completion with fashionable one removing the fine and testing tool of light inlet under completion tubular column, can Production development under monitor well at any time in oil recovery is produced, and go out oil reservoir situation according to downhole temperature, pressure calculation, estimate water logging time and position, later matching Production development, find out the suitable activity duration, under enter closing tool, drag for and can close sliding sleeve inner sleeve, drag to fastening position, close water logging and adopt liquid passage layer by layer, to realize the object adjusting Production development.
Summary of the invention
The utility model provides a kind of supporting intelligent well completion down-hole to adopt liquid channel controller; its object is in oil recovery process; fishing tool closedown can be entered down as required and adopt liquid passage; prevent too early water logging; improve single well production total amount; mate intelligent well completion pipe infrared optical fiber protection requirement simultaneously, prevent optical fiber under enter in process impaired.
The technical solution of the utility model is:
Liquid channel controller is adopted in a kind of intelligent well completion down-hole, comprise cylinder body and the upper and lower joint being connected to cylinder body two ends, wherein: upper lower contact is connected with cylinder body internal thread by external screw thread, and form limiting stand edge in junction, the sliding sleeve be slidably matched with cylinder body is provided with in cylinder interior, sliding sleeve bottom is provided with jump-ring slot and jump ring, be provided with two or more in the upper-outer circumference of cylinder body and adopt liquid passage, be provided with the jump-ring slot coordinated with jump ring at the middle part of cylinder body, the stroke stop point up and down of slide block stops with upper lower contact and coordinates.
Such scheme also comprises: described cylinder body is eccentric cylindrical shell, is axially arranged with groove at its thickened wall place, is locked, be provided with the inner convex platform coordinated with fishing tool on sliding sleeve top between the bottom and sliding sleeve of cylinder body by shear pin.
In cylinder body and upper and lower joint joint portion, and cylinder body and the sliding sleeve face of being slidably matched are equipped with seal.Described seal member comprises rubber seal or metallic packing ring.
This device sliding sleeve can by fishing tool be carried, and after arriving sealing station, jump ring ejects, and sliding sleeve is fixed on sealing station, closes and adopts liquid passage.The cylinder body adopting liquid channel controller adopts eccentric design, and output a protector at webbing, the optical fiber that intelligent well completion uses can embed in protector by during this device again, prevents optical fiber with fashionable impaired under tubing string.
The utility model has the advantages that:
This apparatus structure is simple, and reliability is high, can be suitable for multiple fishing tool; After action of tool puts in place, instruction obviously, effectively can be closed after execution and adopt liquid passage, stops stratum to cross early leaving.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with attached Fig. 1 and 2, the utility model is described in detail.
This intelligent well completion down-hole is adopted liquid channel controller and is formed primarily of lower contact 1, cylinder body 2, sliding sleeve 6 and top connection 7.Cylinder body 2 bottom and the lower contact 1 with seal member are by screwed connection, and lower contact 1 will form boss in cylinder body 2 inside, form lower limit to sliding sleeve 6.Sliding sleeve about 6 is provided with sealing ring.Be carved with jump-ring slot outside sliding sleeve 6, when sliding sleeve is positioned at bottom position, jump ring 4 is hidden in the jump-ring slot of sliding sleeve 6, and now jump ring is inoperative.Sliding sleeve 6 is furnished with pin sky at initial position and cylinder body 2 in relevant position, and sliding over initial position is except boss is spacing to sliding sleeve, or spacing with shear pin 5 pairs of sliding sleeves 6, and anti-anti-skid sheath surprisingly slides.Adopt screwed connection with seal member top connection 7 and cylinder body 2, top connection 7 forms boss cylinder body 2 in, forms upper limit to sliding sleeve 6, and cylinder body 2 top is provided with that 3-5 is individual adopts liquid path 10, is provided with the jump-ring slot 9 that the jump ring that carries with sliding sleeve 6 coordinates in the middle part of cylinder body 2.
Cylinder body 2 cylindrical shell adopts eccentric cylinder structure, axially arranges groove 8(as Fig. 2 at its thickened wall place), can protect the armored fiber optic of intelligent well completion, during construction, optical fiber will embed in protector, can prevent fibre strain and wearing and tearing.
When needs adopt adopt liquid passage under liquid channel controller closed-in well time, can enter below fishing tool drag for sliding sleeve 6 top inner convex platform and on carry, pin 5 on sliding sleeve 6 is cut off, sliding sleeve 6 becomes free state, up with fishing tool, the stop motion when sliding sleeve 6 arrives the convex platform position that top connection 7 formed with cylinder body 2, the jump ring 4 be hidden in sliding sleeve 6 jump-ring slot ejects, enter in jump-ring slot 9 reserved on cylinder body 2, the motion of locking sliding sleeve 6 together with convex platform.Now the adopt liquid passage of sealing ring to cylinder body 2 of sliding sleeve about 6 forms sealing, adopts liquid pathway closure.
