The utility model content:
For overcome the conventional way of the employing that exists in the existing separated-zone water infection oil field field can not realize to the separated-zone water infection oil field amount measure in real time, online adjustment, the problem that test period is long, data accuracy is low, the utility model provides a kind of separated-zone water infection oil field test throttle, this kind separated-zone water infection oil field has the number of times that can realize that zonal flow rate is dynamically adjusted, reduced the pulling blanking plug and changes water nozzle after with test throttle and the supporting use of the adjustable blanking plug of GCU and down-hole, improves testing efficiency and improves the characteristics of data accuracy rate.
The technical solution of the utility model is: this kind separated-zone water infection oil field test throttle, comprise cable head joint, dc motor, Hooks coupling universal coupling, electromagnetic flowmeter, and jack, blanking plug butt joint and a guiding mechanism, the structure of these parts is as follows with concrete annexation:
The cable head joint links to each other with cable link on the dc motor, the fuselage of dc motor is fixed on the hollow connection support of test throttle, the axis of Hooks coupling universal coupling is fixed in the lower end of dc motor power transmission shaft, and the upper end of the turning cylinder of Hooks coupling universal coupling lower end and blanking plug butt joint links.Jack is to adopt two " L " shape steel poles to constitute drive link, two quarter butt ends wherein are connected on the support of blanking plug butt joint, its connected mode is for being rotationally connected, two stock ends wherein are connected to the two ends up and down on the connection support of described test throttle respectively, and its connected mode is also for being rotationally connected.Electromagnetic flowmeter is fixed in the lower end that connects support by double plate root testing seal section, and the guiding mechanism that is made of the steel pole with location sliding recess then is fixed in the lower end of electromagnetic flowmeter by being rotationally connected.
The utlity model has following beneficial effect: because after taking the separated-zone water infection oil field of such scheme to use test throttle and the supporting use of the adjustable blanking plug of GCU and down-hole, can detect the seperated layer water injection amount in real time by electromagnetic flowmeter, and measuring-signal is transferred to ground control system by cable, after comparing with the desired numerical value of geology injection allocation scheme, the output control signal, this control signal control dc motor rotation, and then the opening degree of valve in the adjustable blanking plug under the control well, promptly realized the dynamic adjustment of seperated layer water injection amount, shortened the test regulating cycle, improve operating efficiency, reduced the test operation working strength of workers; In addition, utilize the technical program, need not adopt diminishing method to calculate zonal flow rate again, reduced measure error, improved the qualification rate of data.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-cable head joint among the figure, the 2-dc motor, the 3-Hooks coupling universal coupling, the 4-jack, the butt joint of 5-blanking plug, the 6-water export, the 7-electromagnetic flowmeter, the 8-water stream channel, the 9-guiding mechanism, 10-connects support, 11-double plate root testing seal section.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, this kind separated-zone water infection oil field test throttle, comprise cable head joint 1, dc motor 2, Hooks coupling universal coupling 3, electromagnetic flowmeter 7 and jack 4, blanking plug butt joint 5 and guiding mechanism 9, the structure of these parts, concrete connected mode and the function of being finished separately are as follows:
Cable head joint 1 links to each other with cable link on the dc motor 2, the fuselage of dc motor 2 is fixed on the hollow connection support 10 of test throttle, the axis of Hooks coupling universal coupling 3 is fixed in the power transmission shaft lower end of dc motor 2, and the turning cylinder of Hooks coupling universal coupling 3 lower ends then links with the upper end turning cylinder of blanking plug butt joint 5.
Jack 4 is made of two " L " shape steel poles, two quarter butt ends wherein are connected on the support of blanking plug butt joint 5, its connected mode is for being rotationally connected, two stock ends wherein are connected to the two ends up and down on the connection support 10 of described test throttle respectively, and its connected mode is for being rotationally connected.
When dc motor 2 begins to clockwise rotate under the effect of the control signal that ground control system is sent, Hooks coupling universal coupling 3 begins to do to rotate in the same way under the rotating torque effect that comes from the axle of dc motor 2, under the effect of this rotatory force, blanking plug butt joint 5 is pulled outwardly out along the run-on point on the jack 4.
Electromagnetic flowmeter 7 is fixed in the lower end that connects support 11 by two double plate root testing seal sections 11 as shown in the figure, wherein the effect of water export 6 is and can joins with the flow inlet on the blanking plug, makes the water of process water stream channel 8 to enter the purpose stratum by blanking plug.Guiding mechanism 9 mainly is to be made of a steel pole that has the location sliding recess, it is fixed in the lower end of electromagnetic flowmeter 7 by being rotationally connected, the guide peg of the adjustable blanking plug in down-hole can be along the location sliding recess in it along linear slide, its effect is exactly for adjustable blanking plug location, down-hole, can realize accurate the butt joint to guarantee the water yield adjusting rod that has keyway on the adjustable blanking plug in blanking plug butt joint 5 and down-hole.
When concrete the use, at first this separated-zone water infection oil field correctly is connected with GCU with test throttle, be about to power cable and be connected to dc motor 2 by the part lead in the cable head joint 1, the measuring-signal of electromagnetic flowmeter is also uploaded by the part output cable in the cable head joint 1, the purpose of this configuration is to realize detecting in real time the seperated layer water injection amount, and measuring-signal is transferred to ground control system by cable, after comparing with the desired numerical value of geology injection allocation scheme, output control signal, this control signal can be controlled dc motor 2 rotations.When dc motor 2 turns clockwise, jack 4 beginnings slowly are pulled the back and eject, the keyway that raises pole until blanking plug enters in the adjustable blanking plug butt joint 5 in down-hole, at this moment dc motor will begin to drive the adjustable blanking plug in down-hole and raise pole and be rotated counterclockwise under the effect that comes from the Ground Control signal, because the adjustable blanking plug in down-hole raises the opening degree of valve in the pole control blanking plug, so so far just can realize the dynamic control of flux of separated-zone water infection, and the adjustable blanking plug in down-hole need not be tripped out.
