Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the existing test sealing section used for flow measurement of bridge-type eccentric water distributors is not suitable for small-flow flow measurement of eccentric water distributors without bridges, which will lead to the situation that liquid cannot be injected , the purpose is to provide a flow-collecting and setting structure for small-flow eccentric water distributors without bridges in oil fields. On the basis of the existing test sealing section, by setting flow channels inside it, the eccentric water distributors without bridges After being set, it ensures the smooth flow of the liquid flow without being blocked at the test sealing section

Abstract

The invention discloses a flow-concentration setting structure for an oil field small-flow-rate bridge-free eccentric water distributor. The flow-concentration setting structure comprises a testing sealing section used for a bridge eccentric water distributor. A water inlet is formed in the top of the testing sealing section, and a water outlet is formed in the bottom of the testing sealing section. The testing sealing section is internally provided with a liquid flow channel for communicating the water inlet with the water outlet. According to the flow-concentration setting structure, the flow channel is formed in the structure of an existing testing sealing section, and thus it is ensured that a liquid flow smoothly flows downwards and is prevented from plugging the testing sealing section after the bridge-free eccentric water distributor is subjected to setting.

Description

technical field [0001] The invention relates to a setting structure, in particular to a flow-collecting setting structure for an eccentric water distributor with a small flow rate in an oil field without a bridge. Background technique [0002] Eccentric water distributors without bridges are often used in oil field operations. When measuring the small flow rate of oil wells, because the liquid flow path is too slow, neither ultrasonic nor eddy current can measure the flow at a very slow flow rate, so usually A collecting flowmeter integrated with an electromagnetic flowmeter and a collecting structure is used, but it is found in actual production that the collecting flow measurement needs to make all the liquid flow injected into the inner cavity pipeline of the water distributor pass through the collecting flowmeter, so it is necessary to The central lumen pipeline is set and sealed. The existing test sealing section for the bridge eccentric water distributor has a bridge f...
