A water regulating device capable of detecting plugs and a detection method thereof

Abstract

The invention discloses a water regulating device capable of detecting a blanking plug and a detection method thereof. The water regulating device is placed into a water injection well first, when the water regulating device declines to a corresponding level of the water injection well, the water regulating device opens a popup arm, a regulating arm is extended to be contacted with the end face of the blanking plug of the corresponding level of the water injection well, an umbrella-type connecting head of the top end of the blanking plug is in butt joint with a universal shaft at this moment, a magnetic steel magnetic field on a shaft sleeve at the tail end of the universal shaft can be detected by a Hall element installed on the water regulating device, the magnetic field intensity can correspond to the axial distance of the blanking plug through measurement. According to the axial moving distance, whether blocking exists in the water distributor is judged, the butt joint degree is judged, and whether a cam of the blanking plug is overturned is judged. According to the water regulating device, the state of the blanking plug is detected, whether the blanking plug exists in the water distributor is detected, whether the butt joint is successful is detected, and whether the cam of the blanking plug is overturned is detected. The water regulating device has the advantages of being visual in operation and achieving terrain visualization.

Description

technical field [0001] The patent of the present invention relates to a water regulating device, in particular to a water regulating device capable of detecting a plug and a detection method thereof. Background technique [0002] At present, in the process of oil field development, water is injected into the oil reservoir through special water injection wells to maintain or restore the pressure of the oil layer, so that the oil reservoir has a strong driving force, so as to improve the production speed and recovery rate of the oil reservoir. The development of water injection equipment is an important task, and the water volume adjustment device is an instrument used to adjust the water injection volume of the water injection well. The water injection well is generally multi-layered, and each layer is equipped with a water distributor, and a plug is placed in the water distributor ( Similar to a faucet), the plug is in an eccentric position in the water distributor, the uppe...

[0002]At present, in the process of oilfield development, water is injected into the reservoir through special water injection wells to maintain or restore the pressure of the reservoir, so that the reservoir has a strong driving force, In order to improve the production speed and recovery rate of oil reservoirs, the development of water injection equipment into oil wells is an important task, and the water volume adjustment device is an instrument used to adjust the water injection volume of water injection wells. Water injection wells are generally multi-layered, and each layer There is a water distributor, and a plug (similar to a faucet) is placed in the water distributor. The plug is in an eccentric position in the water distributor. The upper end of the plug is hexagonal for transmission adjustment, and the umbrella-shaped connector is used for the plug. For fishing, the water volume adjustment device goes down to each layer of the well to adjust the plug to realize the flow adjustment of each layer. The plug in the water distributor is in an eccentric position, so the water volume adjustment device needs to extend an arm to dock with the plug to realize the adjustment of the plug. , the existing water regulating device does not have the function of detecting the state of the plug, does not have the function of judging the connection, and operates blindly, so the existing water regulating device is still not perfect
