Abstract

The invention provides a method for generating a steam distribution plan of a heavy oil well. The method for generating the steam distribution plan comprises the steps that step S10, a plurality of to-be-turned wells needing steam injection in a target well area are screened out; step S20, the plurality of to-be-turned wells are sequenced; step S30, each to-be-turned well is detected; step and S40, whether each to-be-turned well has a steam channeling phenomenon or not is judged, if yes, step S41 of selecting to-be-turned wells with the steam channeling phenomenon is executed, and if not, step S42 of reserving the sequencing condition of the to-be-turned wells and step S43 of grouping all the to-be-turned wells without the steam channeling phenomenon to obtain a main to-be-turned well group are executed. According to the technical scheme, the problems that in the prior art, manual well-by-well analysis and discussion are needed to generate a steam distribution plan, and time and labor are wasted are solved, steam injection optimization can be achieved, and the fine management requirement of a heavy oil field is met.

Description

technical field [0001] The invention relates to the technical field of steam distribution for heavy oil wells, in particular to a method for generating a steam distribution plan for heavy oil wells. Background technique [0002] The existing steam distribution management method for conventional heavy oil wells requires manual well-by-well analysis, discussion, and planning, which is time-consuming and laborious. The steam injection volume has not been optimized, and cannot meet the fine management requirements of heavy oil oilfields. Contents of the invention [0003] The main purpose of the present invention is to provide a steam distribution plan generation method for heavy oil wells, so as to solve the time-consuming and labor-intensive problem in the prior art that the steam distribution plan needs to be manually analyzed and discussed one by one, and can realize optimized steam injection to meet the requirements of heavy oil wells. Requirements for refined oilfield ma...
