Embodiment 1

[0045] Such as figure 2As shown, it is a first implementation of step S102 of an Internet of Things-based oil well nitrogen injection machine monitoring method in an embodiment of the present invention; the details are as follows:

[0046] Step S201, according to the classification and accumulation of the received work index parameters according to their categories, it is judged whether the cumulative value corresponding to each type of work index parameter shows a trend increase within a specified time;

[0047] Step S202, if the accumulated value shows a trend increase within the specified time, then the working index parameter corresponding to the accumulated value does not contain a disturbance signal;

[0048] Step S203, if the accumulated value does not show a trend increase within the specified time, then the working index parameter corresponding to the accumulated value contains a disturbance signal;

Embodiment 2

[0050] Such as image 3 As shown, it is a second implementation of step S102 of an Internet of Things-based oil well nitrogen injection machine monitoring method in an embodiment of the present invention; the details are as follows:

[0051] Step S301, judging whether each type of work index parameter appears continuously within the specified time;

[0052] Step S302, if the work index parameter appears continuously within the specified time, the work index parameter does not contain a disturbance signal;

[0053] Step S303, if the work index parameter does not appear continuously within a specified time, then the work index parameter contains a disturbance signal.

[0054] In this embodiment, the working index parameters collected by each sensor in the sensor are transmitted to the controller, after A / D conversion, the controller performs analysis and judgment, and the judgment item is whether it is a disturbance signal. Current monitoring products use pulse-triggered alarm...

Embodiment 3

[0057] It also includes a mobile terminal, through which the corresponding query is sent to the central control system, and the mobile terminal corresponding to the working state of the oil well nitrogen injection machine is called according to the received query command, wherein the mobile terminal is a mobile phone, a tablet computer, Any one or more of Pocket PC, MP4 and MP5. In this embodiment, the corresponding APP program is logged in through the mobile terminal, and the display results of the central control computer are queried or monitored on the mobile terminal.

[0058] When managers need to know the working status of nitrogen injection machines in oil wells all over the country, arrange and adjust the operation of oil fields, they only need to sit in the monitoring room and use the central control computer to inquire about the generation of nitrogen injection machines in each oil well according to their working index parameters. The corresponding chart, or rely on ...

Abstract

The invention provides an internet-of-things-based monitoring method of a nitrogen injection machine of an oil well. The method comprises: a working index parameter of a nitrogen injection machine of an oil well is obtained; whether the working index parameter includes a disturbance signal is determined; if not, the working index parameter is transmitted to a central control computer; whether a fault occurs at the nitrogen injection machine, corresponding to the received working index parameter, of the oil well is detected; if so, the working state of the nitrogen injection machine of the oil well is adjusted according to a preset model; and the working index parameters before and after adjustment are displayed in a graph mode. With the method, a phenomenon that wrong reporting occurs frequently in a monitoring sate because the trigger signals do not include the disturbance signal according to the traditional monitoring way can be avoided, so that the monitoring accuracy is improved. Meanwhile, under the circumstances that the manager is absent, the working state of the nitrogen injection machine of the oil well can be adjusted monitored, thereby realizing convenient arrangement of daily running and operation scheduling of the oil well.

Description

technical field [0001] The invention relates to the technical field of oil field exploitation, in particular to a method for monitoring an oil well nitrogen injection machine based on the Internet of Things. Background technique [0002] As a valuable energy resource, petroleum is widely used. After the first oil recovery, the traditional oil recovery methods are (water injection and natural gas injection), however, there are still 70% of residual oil remaining in the reservoir. Methods of recovering this residual oil are generally referred to as enhanced oil recovery (EOR) methods. Typically, each new approach to enhanced oil recovery involves injecting a fluid into the reservoir to increase the reservoir's energy, improve sweep efficiency, or seek to alter the physical properties of the crude itself. Enhanced oil recovery (EOR) includes thermal recovery (steam or fire formation) methods, which mainly change the physical properties of crude oil (such as making crude oil t...
