Embodiment Construction
[0014] The present invention will be further described below in conjunction with accompanying drawing:
[0015] As shown in Fig. 1, the eccentric water distribution device in double deployment mode includes a water distributor main body 1 and a test sealing section 2. The water distributor main body 1 has a central hole and a plug installation hole, and the central hole on the water distributor main body 1 and the The plug installation hole is equipped with a test sealing section 2 and a plug 3 respectively. The water injection channel 4 is opened on the side wall of the central hole of the water distributor main body 1 , and the water injection channel 4 communicates with the central channel 5 . The test sealing section 2 is a single cup structure, including the sealing section main body 6, the sealing section main body 6 is equipped with an upper leather cup 7, and the sealing section main body 6 has a central channel 5. When in use, its water distribution process is differe...

The invention provides a dual-regulation dispensation type eccentric water-distributing device, the purpose is to solve the problem that the existing conventional water-distributing mode and the bridge type eccentric water-distributing mode cannot be selected optionally according to the allocation and the test demand. The invention is characterized in that: a waterflooding passage (4), which is arranged between a blanking plug mounting hole on a water-distributing main body (1) and a central hole on the water-distributing main body, is opened on the side wall of the central hole of the water-distributing main body (1), the waterflooding passage (4) is communicated with a central passage (5). The dual-regulation dispensation type eccentric water-distributing device combines the advantages of the conventional eccentric water-distributing technology and the bridge-type eccentric water-distributing technology, and can be selected optionally according to the allocation and test demand, which realizes the purpose that the test or debug with the conventional or bridge-type test and debugging method is all possible.
Description
Technical field: [0001] The invention relates to a layered water injection and testing device for an oil field, which belongs to an eccentric water distribution device with a double deployment mode. Background technique: [0002] At present, eccentric water distribution pipe strings are mainly used for water distribution of oilfield water injection wells, and conventional water distribution pipe strings and bridge-type eccentric water distribution pipe strings are commonly used. [0003] The main structure of the existing conventional water distributor has a stopper installation hole. When water is injected, water enters from the bottom of the hole, passes through the stopper and the water nozzle, and enters the formation from the small hole on the side wall of the hole. The sealing section with a single cup structure is used for flow test and sealing inspection. During the flow test, the flowmeter is installed on the upper part of the single sealing section, and the sealing...
