Embodiment Construction

[0029] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0030] The invention provides a multi-station automatic water injection device and a control method thereof.

[0031] Such as figure 1 with figure 2 , image 3 As shown, in the device, the main water inlet pipe 1 is branched into more than one water well injection pipe 2, and a water well flow meter 6 and a water injection flow limiting valve 5 are installed on the water well water injection pipe 2, and the water well water injection pipe 2 injects water into the water injection well 9, and the total inlet A thermometer 7 and a pressure gauge 8 are installed on the water pipe 1. The valve position selection mechanism 4 controls the water injection flow limiting valve 5 through the electric actuator 3. The handle of the water injection flow limiting v...

Abstract

The invention provides a multi-station automatic water injection apparatus and a control method thereof and belongs to the technical field of wellhead water injection for oilfield oil extraction plants. The apparatus comprises a master water incoming pipe, a well injection pipe, an electric actuator, a valve position selector, an injection flow limiting valve, a well flow meter, a thermometer, a pressure meter, an in-place controller, a remote controller and the like. The in-place controller receives each injection well injection quantity parameter of the remote controller; parameter output of the in-place controller is converted into a valve position set value for the injection flow limiting valve of each injection well. By using the apparatus and the method, one-off investment and operation cost of a system are reduced, unattended automatic injection can be provided for an injection chamber, and labor intensity is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of wellhead water injection in an oil production plant in an oil field, in particular to a multi-station automatic water injection device and a control method thereof. Background technique [0002] After the wellhead of the oil production plant is put into production, as the production time increases, the energy of the underground oil layer itself is continuously consumed, resulting in a continuous drop in oil layer pressure, and a large amount of degassing of underground crude oil, resulting in increased viscosity, greatly reduced oil well production, and even shutdown. Spraying stopped production, resulting in a large amount of dead oil left underground that could not be exploited. In order to make up for the underground deficit caused by the extraction of crude oil and other liquids, maintain or increase the pressure of the oil layer, achieve high and stable oil production, and obtain a certain recovery r...
