Description
Technical field
The utility model relates to a kind of injection well downhole flow regulator that is applicable to petroleum gas field water injection well, specifically is a kind ofly can be for a long time to survey water flow regulator in the cable type water injection well intelligence of underground work.
Background technology
The injection well downhole flow regulator that petroleum gas field water injection well is commonly used at present mainly contains following several kinds:
(1) traditional retrievable type injection well downhole flow regulator: mainly be through instruments such as steel wires the down-hole water nozzle to be carried out pulling, so its shortcoming comprises the following aspects: 1. real-time is poor, can not regulate water nozzle according to downhole conditions timely; 2. water distribution precision is low, can not realize the seperated layer water injection that the down-hole is meticulous; 3. pulling workload is big, and the instrument of pulling is more complicated also, and when high angle hole or horizontal well construction, the pulling success rate is also lower.
(2) memory-type is surveyed water flow regulator: the water filling value of this injection well downhole flow regulator good each water filling layer of preset in advance on ground; When the flow value that records and preset value differed above certain limit, the down-hole control chip was then controlled motor and is rotated and adjust the water nozzle aperture and accomplish Flow-rate adjustment.Its shortcoming is: 1. real-time is poor, can not find the fluctuation of underground water-injection amount timely; 2. can't carry out direct-reading and monitoring to pressure, temperature, data on flows, flow allocating process and the changes in flow rate of each layer position, down-hole in real time; 3. when needs people seperated layer water injection amount for a change, must take out injection well downhole flow regulator and reset or be lowered to Other Instruments completion setting, workload is bigger, and is also more time-consuming.4. the power supply of this injection well downhole flow regulator is provided by the down-hole battery usually, and cost is than higher, and the allotment time is also limited, need regularly take out injection well downhole flow regulator and change battery, and workload is big.
(3) the allotment water method while surveying: this method is lowered to the downhole deployment tester with cable, after sitting layer success, through regulating the aperture size of water nozzle; Realize laminated distributor under well flood effectiveness preferably, also realized the function of real-time monitoring, but itself also has shortcoming: 1. owing to each accent of surveying only carries out promptly taking out instrument behind the several hrs; The downhole water flow regulator water nozzle is in stationary state; If when fluctuation appearred in strata pressure or water injection pressure, injection well downhole flow regulator can't be realized automatic adjustment, causes water filling inaccurate; 2. the flow that can only realize the short time is monitored in real time, can't realize long term monitoring; 3. when needs are regulated zonal flow rate, must accomplish the seat layer earlier and just can regulate, complex procedures, workload is bigger; During 4. to water nozzle pulling or adjusting, also can face high angle hole and horizontal well and be difficult for problems such as butt joint; 5. when the needs testing seal about packer, need the special-purpose seal-checking instrument of pulling once more could realize testing envelope.
Summary of the invention
It is poor that the utility model purpose is to solve existing injection well downhole flow regulator real-time; Can't carry out direct-reading and monitoring to down-hole pressure, temperature, data on flows, flow allocating process and changes in flow rate in real time for a long time; Face the problem that high angle hole and horizontal well are difficult for butt joint when water nozzle pulling or adjusting.
The cable type water injection well intelligence that the utility model provided is surveyed water flow regulator and is realized by following technical scheme:

Above-mentioned top connection is provided with the last cable seal head that is used for hermetically-sealed cable, and cable cable seal head access from power on back is connected with motor with Flow-rate adjustment control pipe nipple.
Above-mentioned lower contact is provided with the following cable seal head that is used for hermetically-sealed cable, and cable cable seal head access from power on back is connected with motor with the Flow-rate adjustment control pipe nipple of another cable type water injection well intelligence survey water flow regulator after the cable seal head picks out down.
The above-mentioned cable seal head of going up adopts sealing of double sealing circle or the sealing of conical surface seal spare with following cable seal head.
Above-mentioned flow measurement pipe nipple internal components is fixture.
It is following that cable type water injection well intelligence is surveyed the water flow regulator advantage:
(1) use a cable in real time down-hole pressure, temperature, data on flows, flow allocating process and changes in flow rate to be carried out direct-reading and monitoring for a long time.
(2) the Flow-rate adjustment control pipe nipple of surveying water flow regulator through cable to downhole intelligent on ground sends control command, down-hole each layer water injection rate size is carried out the manual work adjustment, to reach the expection water injection rate.
(3) cable type intelligence survey water flow regulator can be implemented in the down-hole and records data by the flow measurement pipe nipple, and regulates water nozzle in real time automatically through Flow-rate adjustment control pipe nipple and carry out flow measuring and adjusting.
(4) power supply of cable type intelligence survey water flow regulator is provided by ground; Not to provide, so not only practiced thrift cost, dwindled the overall volume of injection well downhole flow regulator by the down-hole battery; But also prolonged the time of injection well downhole flow regulator greatly in underground work, make the water injection rate allotment more abundant.
(5) because cable type intelligence survey water flow regulator is an integral structure, therefore do not need the pulling water nozzle, shortened the allotment time, reduced labour intensity, and also can extensive use at high angle hole and horizontal well.
