Abstract

The invention discloses a method and device for determining a hot washing cycle, which can obtain parameter values ​​of various parameters before and after hot washing of at least one oil production well under a plurality of different hot washing cycles, and according to the parameter values ​​of the various parameters Determining the effective stroke of the pumping unit, the load range and the balance degree of the pumping unit before and after the heat washing of the at least one oil production well under a plurality of different heat cleaning cycles; according to the effective stroke of the pumping unit, the load limit The difference and the balance degree of the pumping unit obtain at least one hot washing cycle that meets the preset hot washing effect requirements. The invention can automatically determine the hot washing cycle meeting the preset hot washing effect requirements according to various parameters, and solves the problem of insufficient accuracy caused by manually setting the hot washing cycle.

Description

technical field [0001] The invention relates to the technical field of petroleum exploitation, in particular to a method and a device for determining a hot washing cycle. Background technique [0002] In the process of oil extraction, the wax in the oil is easy to condense on the inner wall of the oil pipe due to low temperature when it is transported in the oil pipe of the oil production well. This phenomenon is called wax deposition. Wax build-up results in a smaller pore size in the tubing, which in turn results in less oil being transported and lower oil production. Hot washing is a method of removing condensed wax through high-temperature liquid, which can effectively reduce the adverse effects of wax deposition. [0003] As the production of oil production wells, the phenomenon of wax deposition will gradually become serious, so it is necessary to perform hot washing on oil production wells on a regular basis. In the prior art, technicians manually set the hot washin...
