Method for guiding oil well dosing by utilizing oil well indicator diagram data

Abstract

The invention provides a method for guiding oil well dosing by utilizing oil well indicator diagram data. The method is characterized in that an intelligent oil well dosing system is used for conducting periodic dosing in an oil well, the dosing amount in the first period is the basic dosing amount A, then the dosing amount in each period is determined according to the load amplification of an oilwell ground indicator diagram in the previous period, intelligent regulation and control of the oil well dosing system can be achieved through oil well indicator diagram data, the dosing amount of the oil well paraffin remover and inhibitor is automatically set, and intelligent oil well dosing is achieved. According to the method, the labor intensity of worker dosing can be greatly reduced, the use frequency of workers and vehicles can be effectively reduced, the dosing frequency and the dosage can be finely controlled, the wellhead dosing cost can be reduced, and the pump inspection period and the hot washing period of the oil well can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of digitization in the petroleum industry, and in particular relates to a method for guiding oil well dosing by using oil well dynamometer data. Background technique [0002] In the process of crude oil production, wax deposition and fouling will occur in the wellbore of the oil well and the export pipeline, which will cause problems such as increased load, increased back pressure, and increased failure rate, which seriously affect the normal production of the oil well. In order to achieve sustained and stable production, it is necessary to add paraffin removers, scale inhibitors and other chemicals to the wellbore and export pipelines in time, so as to achieve the purposes of wax prevention and corrosion inhibition. [0003] At present, the traditional way of adding medicine to the wellhead of oil wells in Changqing Oilfield generally adopts the traditional method of manually going into the well regularly, ...

Problems solved by technology

[0003] At present, the traditional way of adding medicine to the wellhead of oil wells in Changqing Oilfield generally adopts the traditional method of manually going into the well regularly, and uses a mobile dosing vehicle or a simple airtight dosing tank to add quantitative medicine at one time from the annular space of the oil jacket, which has high labor intensity, low work efficiency, and high cost. High, dosing in remote wells cannot be guaranteed, and the effect is difficult to guarantee due to weather and other factors

A small number of oil wells have been equipped with wellhead dosing devices to realize regular dosing and remote control, but the dosing time and dosing volume still need to be manually set, and the refined and scientific management of dosing has not yet been realized, which is far from meeting the digitalization of oilfields development needs
