Problems solved by technology

However, since there are many factors affecting the system efficiency, such as the submergence, stroke and pumping depth of the oil pump in the oil and gas well, the liquid production rate and water cut of the oil and gas well, the influencing factors determined by the field staff through experience judgment , is probably not the most critical factor affecting the system efficiency of oil and gas wells

Embodiment Construction

[0049] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0050] figure 1 It is a schematic flowchart of a method for determining the degree of influence provided by the embodiment of the present invention. see figure 1 , the method includes the following steps.

[0051] Step 101: Obtain the system efficiency of each oil and gas well among the plurality of oil and gas wells, and multiple production data of each oil and gas well, where the multiple production data correspond to multiple production parameters one by one.

[0052] Step 102: Based on the system efficiency of the multiple oil and gas wells and multiple production data of each oil and gas well, determine a fitting line corresponding to each production parameter among the multiple production parameters.

[0053] Step 103: Taking th...

Abstract

The invention discloses a method and a device for determining the influence degree, and a storage medium, belonging to the field of oil production and gas production engineering of the petroleum industry. The invention respectively determines a fitting straight line corresponding to each production parameter by acquiring system efficiency of each oil and gas well in a plurality of oil and gas wells, and neutralizing production data of each oil and gas well and a plurality of production data corresponding to a plurality of production parameters one by one. Since the slope of the fitting straight line corresponding to each production parameter can reflect the variation trend between each production parameter and the system efficiency of the oil and gas well, the influence degree of each production parameter on the system efficiency of the oil and gas well can be determined based on the fitting straight lines corresponding to the plurality of production parameters respectively. The invention avoids the malpractice that the field workers only take measures against the specific production parameters which affect the system efficiency of oil and gas wells in the process of adjusting oiland gas wells, and thus improves the adjustment efficiency of oil and gas wells.

Description

technical field [0001] The invention relates to the field of oil and gas recovery engineering in the petroleum industry, in particular to a method, device and storage medium for determining the degree of influence. Background technique [0002] During the production process of oil and gas wells, most oil and gas wells cannot achieve self-flowing production as the bottom hole pressure of oil and gas wells decreases. Therefore, the continuous production of oil and gas wells through mechanical oil recovery has been widely used. For example, at present, most oil and gas wells use pumping machines to achieve continuous production of oil and gas wells. When oil and gas wells are produced by means of mechanical oil recovery, the system efficiency of oil and gas wells is an important index to evaluate the management level of oil and gas wells. Among them, the system efficiency of an oil and gas well refers to the ratio of the effective working energy for lifting the downhole liquid...
