Embodiment Construction

[0049] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0050] Such as figure 1 Shown, a kind of Internet of things intelligent thermal cleaning method for waxing, comprises the following steps:

[0051] Step S1, obtain the dynamometer diagram from the oilfield intranet, and determine whether it is necessary to wash the well and remove wax;

[0052] Step S2, if it is determined that the well needs to be cleaned to remove wax, that is, send a start command to the wax remover to perform three-stage temperature wax removal;

[0053] Step S3, if there is no change in the dynamometer diagram after washing the well and removing wax, a completion command is sent to the wax remover, and the wax remover stops running.

[0054] In the actual operation process, it is necessary to judge whether there is w...

Abstract

The invention discloses a method and a system for intelligently thermally washing and removing paraffin by the aid of an internet of things. The method includes acquiring indicator diagrams from internal networks of oil fields and judging whether well flushing and paraffin removing are required or not; transmitting starting commands to paraffin removing machines if well flushing and paraffin removing are required and executing three-stage temperature paraffin removing; transmitting completion commands to the paraffin removing machines if the indicator diagrams are not changed after well flushing and paraffin removing are completely executed, stopping the paraffin removing machines from running, monitoring paraffin removing data and oil well data by the aid of the system in real time and feeding the paraffin removing data and the oil well data to intelligent paraffin removing network control platforms. The method and the system have the advantages that well flushing and paraffin removing can be intelligentized, processes are simple, obvious paraffin removing effects can be realized, and damage to oil wells due to the traditional paraffin removing modes can be prevented; intelligentization, informatization, the internet of things and big data processing technologies are applied, accordingly, paraffin removing equipment can be remotely digitally operated and monitored, oil well paraffin deposit can be warned, automatic paraffin removing and well flushing can be carried out according to well flushing strategies, and unattended operation can be implemented.

Description

technical field [0001] The invention relates to an Internet of Things technology, in particular to an Internet of Things intelligent thermal wax removal method and system. Background technique [0002] Oil well wax deposition is an inevitable problem in the oil production process. Oil well wax removal equipment is an important support equipment in oil well operation, and it is also a kind of mobile field operation equipment. Due to various reasons, oil well wax removal equipment has been in the extensive mode. At the same time, many problems such as difficult operation status monitoring, maintenance status monitoring, and operator supervision have a great impact on oil production, which is one of the problems that need to be solved in the construction of "digital oilfields". [0003] Patent application number: CN01128456.0 discloses a method and device for fully automatic intelligent measurement and control of wax removal process, which mainly consists of single board comput...
