Intelligent water injection instrument for oil field

Abstract

The invention provides an intelligent water injection instrument for an oil field. The intelligent water injection instrument comprises a water injection instrument main body, wherein the periphery ofthe water injection instrument main body is provided with a thermal insulation layer, a first temperature detector is arranged on the water injection instrument main body and located on the outer side of the thermal insulation layer, a second temperature detector is arranged on the water injection instrument main body and located on the inner side of the thermal insulation layer, a water injectorcontroller and temperature controller assembly and a first heater are also arranged on the water injection instrument main body in the thermal insulation layer, the first temperature detector, the second temperature detector, the water injector controller and temperature controller assembly and the first heater are connected with one another, the first temperature detector and the second temperature detector are used for detecting temperatures of environments inside and outside the thermal insulation layer and sending temperature data to the water injector controller and temperature controller assembly, and the water injector controller and temperature controller assembly is used for controlling the first heater to work, so that the temperature of the environment inside the thermal insulation layer is increased, and the problem that an existing intelligent water injection instrument for the oil field cannot operate at low temperature is solved.

Description

technical field [0001] The present application relates to the technical field of oilfield water injection, in particular to an intelligent water injection instrument for oilfields. Background technique [0002] The use of water injection wells to inject water into the oil layer to supplement and maintain the pressure of the oil layer is called water injection. After the oil field is put into development, with the increase of production time, the energy of the oil layer itself will be continuously consumed, resulting in a continuous drop in the pressure of the oil layer, a large amount of degassing of the underground crude oil, an increase in the viscosity, a great reduction in the production of the oil well, and even the stop of spraying and production, resulting in underground A large amount of dead oil remains and cannot be recovered. In order to make up for the underground deficit caused by the extraction of crude oil, maintain or increase the pressure of the oil layer, ...

AI Technical Summary

Problems solved by technology

[0005] This application provides an intelligent water injection instrument for oilfields to solve the defect that the water injector cannot work normally due to the low temperature in the oilfield water injection process where the ambient temperature is low, and cannot meet the requirements for use in a lower temperature environment. question
