Cabled intelligent separate injection system capable of being monitored in real time and using method thereof

Abstract

The invention discloses a cabled intelligent separate injection system capable of being monitored in real time and a using method thereof. The cabled intelligent separate injection system comprises a water injection well opening, a cable pressure prevention mechanism is arranged on the outer side of the water injection well opening, a hanger is fixedly connected to the bottom of the water injection well opening, a lifting short section is fixedly connected to the outer side of the hanger, a pipe column is fixedly connected with the bottom of the lifting short section, and the position, located below the lifting short section, of the outer side of the pipe column is fixedly connected with a depth correction short section. The cabled intelligent separate injection system is compact in structure, simple and convenient top operate and high in practicability, an electricity-approaching alarm and a monitoring camera are arranged at the well bottom and connected with a ground control cabinet and a central control computer, and therefore, the condition at the well bottom can be monitored and controlled in real time; and meanwhile, a cabled pressure-proof mechanism is arranged at the water injection well opening, so that a signal cable can be prevented from being damaged or even broken by extrusion when an oil pipe is pulled out of the cabled intelligent separate injection system, the maintenance time is greatly shortened, the cost is saved, and practical application is facilitated.

Description

technical field [0001] The invention belongs to the technical field of intelligent dispensing systems, in particular to a cable intelligent dispensing system capable of real-time monitoring and a method for using the same. Background technique [0002] In the existing life, the water injection equipment is used to inject water of acceptable quality from the water injection well into the oil layer to maintain the pressure of the oil layer. This process is called oil field water injection. One of the important means, the level of water injection well management technology determines the quality of oilfield development, and also determines the length of oilfield development life. With the advancement of science and technology, cabled intelligent injection systems have gradually entered the market The cable intelligent dispensing system can better perform stratified water injection on the inside of the water injection well. [0003] However, in the actual application process of...

Problems solved by technology

[0003] However, in the actual application process of the existing cable intelligent dispensing system, due to the lack of real-time monitoring function, when an emergency situation occurs at the bottom of the well, the ground control equipment cannot monitor and control the situation at the bottom of the well in real time. As a result, the overall operation of the system has been greatly affected. At the same time, when the existing cabled intelligent dispensing system is lifting and lowering the oil pipe, the elevator at the wellhead is very easy to rotate or swing at the wellhead driven by the pipe string, and the cable is easy to be hoisted. The card is damaged or even broken. In the initial stage of the construction and application of the cable intelligent dispensing process, this situation occurs from time to time, which not only delays the working hours, but also increases the cost, which is not conducive to the actual application.
