Further; Shown in figure 10; Club 10 comprises that the leather cup 15, center-pole 16 and the tail that connect successively block up 17, on center-pole 16, is provided with lug boss 18, and pawl spring 19 is sheathed on center-pole 16 outsides; Pawl spring 19 matches with lug boss 18 and merges and can endwisely slip along center-pole 16, and pawl spring 19 is connected through cutting off pin 20 with center-pole 16.After club 10 drops into central tubes, at first be provided with first setting portion 21, the first and set the downside that portion 21 is positioned at feed liquor through hole 43 of matching with club 10 in the bottom of first central tube 11; Club 10 falls, be provided with in the bottom of the adapter sleeve 65 of part flow arrangement 6 match with club 10 second set portion 22, make club 10 to set portion 21 and second like this and set portion's 22 realizations setting central tube first.In use, club 10 drops in the central tube, at first sets in first and sets portion 21; After accomplishing packing, center-pole 16 is passed to external force and cuts off pin 20 under the promotion of external force; When external force reaches the rated value of cutting off pin 20, to cut off pin 20 and cut off, center-pole 16 is descending; Pawl spring 19 is separated with lug boss 18, and pawl spring 19 pressurizeds shrink, and makes club 10 can pass first and sets portion 21 and fall to second and set portion 22 and realize setting; To guarantee that the liquid in the tested horizontal well water detection well section is plugged in the central tube, to extract operation.
The present invention is directed to high moisture open-hole horizontal well; Analyse according to the geology five equilibrium net horizontal section is divided into several purpose horizontal segments; Utilize then oil pipe with the upper and lower packer of horizontal well water detection, and kit (comprising pressure and temperature meter 9) be lowered to the planned well section; Utilize aspirator production, and through chemically examining the fluid properties of moisture this horizontal segment of judgement.Temperature, pressure when simultaneously the pressure of memory-type and temperature meter can write down this horizontal segment and produce changes, and treats instrument is proposed to carry out playback behind the ground, just can draw the fracture development status of this horizontal segment, for the measure of following step of this horizontal segment provides foundation.
Operating principle of the present invention is: under the open-hole horizontal well searching pipe column of the present invention behind design attitude; Drop into club 10, oil pipe is applied certain pressure and keeps this pressure above the regular hour, expand fully to guarantee long packing element type water detection upper packer 5 and lower packet 7; Slowly transferring the central tube continued suppresses up to pressure release; At this moment, the disconnected stratum of sealing layer is communicated with through part flow arrangement and central tube are interior, and the liquid in the stratum can enter in the central tube; Utilize aspirator production that liquid is pumped into ground, and through chemically examining the fluid properties of moisture this horizontal segment of judgement.After payzone character is clear and definite; The upper lifting pipe post is to another interval; The process that repeats above-mentioned input club liquid entering oil pipe to the stratum finishes until water detection; In the time of each interval water detection, the pressure of memory-type and temperature meter record relevant pressure, temperature variations are treated measuring appliance is proposed to carry out playback behind the ground.
The course of work of the present invention is: the box cupling of hydraulic base sealed instrument is connected with the top connection of long packing element type water detection upper packer, and the lower surface of the lower contact of hydraulic base sealed instrument is enclosed within on the upper surface of second central tube.When setting, club drops into oil pipe, and club is under the effect of fluid power; Be sitting on the inclined-plane of 30 degree on first central tube of hydraulic base sealed instrument; Continue pressurization, liquid gets into through the feed liquor through hole on first central tube, and axis gets into long packing element type water detection upper packer 5 to flow-guiding channel 42 and flow-guiding channel 491; Through second top connection 53 axially on the hole get in the first folded end play 52 of first packing element 51 and second central tube 12; Liquid continues downwards, and through the axial passage 62 of baffle 63, the fluid course that reaches baffle 63, outer connector 64, adapter sleeve 65 gets into lower packet 7; The lower contact of lower packet 7 is connected to plug 14, and the inside of whole like this tubing string has just formed annular seal space.Along with the 15MPa left and right sides packer that is elevated to of pressure sets fully; Transfer tubing string (central tube is descending); Close the inlet opening on first central tube of hydraulic base sealed instrument, packer 5,7 is in the state of setting always like this, continues pressurization and destroys club 10; Club 10 is fallen the inside of the connector 55 of long packing element type water detection upper packer 5, accomplishes setting of packer 5,7.
During deblocking, the upper lifting pipe post makes the feed liquor through hole 43 of the central tube of hydraulic base sealed instrument open like this, and liquid gets into central tube through the radial direction through hole 61 that feed liquor through hole 43 and baffle 63 footpaths make progress, and makes oily central tube balance, the packer deblocking.
Open-hole horizontal well water detecting and plugging pipe column of the present invention can realize that open-hole horizontal well looks for water blockoff, and can be in horizontal segment water detection step by step.Set reliably, deblocking is simple, and long packing element type water detection upper packer of the present invention adopts hydraulic setting, on carry deblocking, maximum outside diameter is Φ 120mm, minimum in latus rectum Φ 46mm; Total length 2435mm can repeatedly set and deblocking; Hydraulic setting instrument maximum outside diameter is Φ 114mm, minimum interior latus rectum Φ 40mm; Total length 1469mm; Horizontal well uses club 10 maximum outside diameters to be Φ 43mm, total length 448.5mm, and shear pin 9 is cut off pressure 15MPa.
The present invention mainly by the upper and lower packer of horizontal well water detection, set kits such as club, hydraulic setting instrument, part flow arrangement, horizontal well centralizer, pumping system and form.Oil pipe, centralizer, upper packer, centralizer, part flow arrangement, lower packet be connected with club recover etc. be lowered in the pit shaft, the water detection upper packer must with the supporting use of pitching bar setting tool.After dropping into club from well head during work; Oil pipe is applied certain pressure, send into club on the ball seat (first sets portion 21 and second sets portion 22) in the setting tool, and keep this pressure above the regular hour; Packing element to guarantee upper packer and lower packet expands fully; The time of recommending is to want at least more than 15 minutes, slowly transfers the tubing string continued and suppresses up to pressure release, makes packer seal the oil jacket annular space all the time.At this moment, the disconnected stratum of sealing layer is communicated with central tube through part flow arrangement, and the liquid in the stratum can enter in the central tube; Utilize aspirator production that liquid is pumped into ground; And through the fluid properties of moisture this horizontal segment of judgement of chemical examination, after payzone character was clear and definite, the upper lifting pipe post was to another interval; The process that repeats above-mentioned input club liquid entering oil pipe to the stratum finishes until water detection; In the time of each interval water detection, the pressure of memory-type and temperature meter record relevant temperature, pressure changing are treated measuring appliance is proposed to carry out playback behind the ground.
The above is merely the schematic specific embodiment of the present invention, is not in order to limit scope of the present invention.Any those skilled in the art, equivalent variations of under the prerequisite that does not break away from design of the present invention and principle, having done and modification all should belong to the scope that the present invention protects.
