Embodiment Construction

[0086] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0087] Before explaining in detail the oil well fishing method provided in the embodiment of the present application, the application scenario and the oil fishing device provided in the embodiment of the present application are firstly introduced.

[0088] First, the application scenarios involved in the embodiments of the present application are introduced.

[0089] Due to the poor economic benefits of continuous mechanical recovery lifting in low-permeability and low-yield oilfields, oil extraction is mainly used for production. At present, most of them use mobile oil extraction vehicles to extract oil, with many staffing, long driving distance and time, high fuel consumption of tank cars, low oil extraction efficiency and high...

Abstract

The invention discloses an oil fishing method and device for an oil well and a storage medium, and belongs to the technical field of oil field exploitation. The method comprises the steps that according to input parameters of the target oil well, an oil extraction mode corresponding to the target oil well is determined from an oil pumping mode and an oil fishing mode; when determining that the oil extraction mode corresponding to the target oil well is the oil fishing mode, an oil fishing period for fishing oil for the target oil well is determined according to oil well parameters of the target oil well; and according to the oil fishing period, oil fishing equipment is controlled to move to the target oil well on a preset track so as to fish oil for the target oil well. According to the oil fishing method and device for the oil well and the storage medium, whether the exploitation mode of the target oil well is the oil pumping mode or the oil fishing mode can be selected according to the input parameters of the target oil well, the oil fishing period is determined when the exploitation mode is the oil fishing mode, the oil fishing equipment is controlled to move on the preset track according to the oil fishing period so as to fish oil for the target oil well, and the productivity and economic benefits of the low-permeability and low-yield oil well are improved.

Description

technical field [0001] The present application relates to the technical field of oilfield exploitation, in particular to a method, device and storage medium for oil well extraction. Background technique [0002] With the increasing demand for oil, more and more attention has been paid to the exploration and development of low-permeability and low-yield oil, and a large number of such oil fields have entered the stage of exploitation. At present, low-permeability and low-yield oilfields can be produced by fishing. However, due to the characteristics of low-permeability and low-yield oilfields, when low-permeability and low-yield oilfields are usually exploited, the low-permeability and low-yield oilfields may be inappropriate due to the selection of mining methods, or the method of fishing Improperly lead to low production capacity and poor economic benefits, therefore, a method for fishing oil wells is urgently needed. Contents of the invention [0003] The application pr...
