Abstract
The utility model discloses a packer checking tester for water injection well, which is mainly composed of a rope cap, a sealing section and a manometer from top to bottom; wherein, the position between the rope cap and the sealing section is connected with an upper centering device and a measuring meter of three parameters of temperature, pressure and flow quantity, the position between the sealing section and the manometer is connected with a lower centering device. The utility model solves the problems of that the failure of the sealing ring of the prior sealing checking meter has effect on the estimation on the sealing performance of the packer, and the apparatus meets with big friction resistance when in slant wells an positioning wells, which makes the positioning piece always opens on the midway, therefore broadens the range of application of the sealing checking meter.
Description
One, technical field
The utility model relates to a kind of water injection well in oil fields testing seal about packer test isolated plant, and particularly a kind of water injection well hydraulic compression type packer is tested the envelope tester.
Two, background technology
The oil field development water filling is the important measures that keep formation pressure, improve recovery ratio, and seperated layer water injection is a kind of means that waterflooding oil field solves interlayer contradiction.Present domestic most of separate water injection wells, adopt hydraulic compression type packer and eccentric injection mandrel to form separate layer water injection string, each layer is lowered to an eccentric injection mandrel, dress blanking plug in the eccentric injection mandrel, by water nozzle the water injection rate of each layer is allocated, match with various testers simultaneously, finish some tests water injection well.Under the hydraulic compression type packer in the middle of two oil reservoirs of need dispensing, two oil reservoirs are separated up and down, do not gang up mutually, reach the purpose of seperated layer water injection, therefore check the sealing of downhole packer, be an important process in the separated-zone water infection oil field management, waterflooding extraction is had crucial meaning.
At present, the testing seal about packer tester of field by using mainly is made up of " upper pressure meter (sensor)+intermediate seal section+bottom pressure gauge (sensor) ", the disclosed electron pressure seal-checking instrument of Chinese patent (patent No. CN02247119.7) promptly belongs to this type, its operating principle is: seal-checking instrument is lowered in the water injection well with steel wire, the seal section seat is in eccentric injection mandrel, make packer form two independently pressure systems up and down, seal section respectively connects an independent conventional pressure gauge up and down, the exciting stressor layer of top pressure instrumentation, promptly with ground flood pattern pressure communication, following pressure gauge geodetic stressor layer, by manual change's water injection well STP, promptly " drive a well-closing well-drive a well ", every change one action pressure stability water filling 10 minutes promptly changes the pressure that the upper pressure meter is surveyed, and trips out to carry out data with playback apparatus behind the instrument and explain, relatively whether the force value of two pressure gauges under same working system be consistent, judges with this whether this layer packer seals.If the force value that the bottom pressure gauge records can not change with the change of ground pressure, should be a pressure stable value, then this layer packer sealing be good, otherwise, if the bottom force value changes i.e. this layer of decidable packer blow-by along with the change of upper pressure.
There is tangible weak point in using at the scene in the existing envelope tester of testing: the one, and whether the sealing ring that instrument self can not be judged the seal section place exactly has leakage, that is to say if the bottom force value changes along with the change of upper pressure, instrument can not be got rid of because the sealing ring leakage causes, still be because the packer blow-by causes, can not accurately judge the sealing of packer; The 2nd, incompatible tiltedly straight water injection well of instrument and high-inclination directional well are tested envelope, and existing instrument is in this class well, and instrument removes often is close to tube inner wall in the process, frictional resistance increases, cam rubs mutually with tube inner wall, and locating piece is usually opened midway, causes seal-checking instrument not remove smoothly in pit shaft.
Three, summary of the invention
The purpose of this utility model provides a kind of water injection well testing seal about packer tester, with the accuracy of raising packer sealing judgement, and solves the problem that existing seal-checking instrument can not remove smoothly in pit shaft.
For reaching this purpose, the technical scheme that the utility model is taked is: a kind of water injection well testing seal about packer tester, mainly form from top to bottom by rope socket, seal section, pressure gauge, and between rope socket and seal section, be connected with temperature, pressure, flow three-parameter measuring instrument.
In the such scheme, be connected with centralizer between described rope socket and temperature, pressure, the flow three-parameter measuring instrument, between seal section and pressure gauge, be connected with centralizer down.
After adopting technique scheme, by the pressure gauge on existing seal-checking instrument top being replaced by temperature, pressure, flow three-parameter measuring instrument, increased flow parameter, if the seal section sealing ring is missed, wastage will be reflected on the three-parameter measuring instrument with the form of flow, thereby can accurately judge the sealing of packer; Simultaneously, by on existing seal-checking instrument, upper and lower centralizer being set, guarantee that instrument removes in the process to occupy all the time in the middle of the oil pipe that it is big to have solved instrument frictional resistance in tiltedly straight well and high-inclination directional well, the problem that locating piece is usually opened midway, thus the scope of application of seal-checking instrument widened.
Four, description of drawings
Fig. 1 is the utility model structural representation.
Five, the specific embodiment
As shown in Figure 1, the utility model is made up of rope socket 1, last centralizer 2, temperature, pressure, flow three-parameter measuring instrument 3, seal section 4, following centralizer 5, pressure gauge 6 from top to bottom.
With three sections of secondarys (secondary packer, three layers of injection well downhole flow regulator) separate water injection well, second level packer is tested envelope is example below, concrete working method of the present utility model is described:
The first step is gone into the well
The separate water injection well of need being tested the envelope test stops water filling, the place connects lubricator at the test valve, the utility model is gone into the well by piano wire by lubricator, directly descended the 3rd layer of eccentric injection mandrel, carry on slow then, this moment, locating piece was opened, and went in the 3rd layer of eccentric injection mandrel by the guide effect seat, sealing ring expands eccentric injection mandrel is separated the end of so far going into the well up and down.
In second step, adjust the ground water injection pressure
Well head begins water filling, and the water filling oil pressure was stablized 10 minutes, and closing well stops water filling and stablized 10 minutes then, and the water filling and the water filling oil pressure was stablized 10 minutes of driving a well once more stops water filling at last, treats to trip out the utility model after the pressure diffusion.
In the 3rd step, playback is explained
Explain in the enterprising line data playback of playback apparatus, judge the sealing performance of packer.If the pressure that pressure gauge 6 records can not change with the pressure change of landing ground " oco " operation, then packer sealing is good; If the pressure that pressure gauge 6 records changes with landing ground " oco " pressure change, simultaneously, if the flow curve of temperature, pressure, flow three-parameter measuring instrument 3 records shows there is not flow, then get rid of the possibility of sealing ring leakage, and then can judge this packer blow-by exactly.
