Problems solved by technology
[0003] Due to the different experiences and abilities of researchers, the analogy parameters are often chosen differently, which leads to the diversification of analogy results.
At the same time, when screening similar oilfields, the oilfield similarity calculation only considers the analogy parameter values, ignoring the geological significance of the analogy parameters, resulting in large differences between the screening results and the research oilfields, and the reliability of the analogy results is poor

The invention provides a method for screening similar oil fields, comprising: a reference parameter screening step, screening reference parameters according to the relationship between the analogy target and its influencing factors; an oil field screening step, calculating the similarity between the sample oil field and the analog oil field according to the reference parameters and based on The similarity screens sample oil fields; the screening result checking step is to check the reliability of the screening results according to the standard deviation of the benchmark parameters in the screened sample oil fields and analog oil fields. The invention improves the screening efficiency of similar oil fields and the reliability of analogy results.
Description
technical field [0001] The invention relates to the technical field of oil and gas field development, in particular to a method for screening similar oil fields. Background technique [0002] In the process of oil and gas field development, the analogy method is often used to understand the development law and predict the development index of the reservoir in the early stage of development. When selecting oilfield analog parameters, the analog parameters and parameter weights are mostly determined based on experience or single factor analysis. [0003] Due to the different experiences and abilities of researchers, the analogy parameters chosen are often different, which leads to the diversification of analogy results. At the same time, when screening similar oilfields, the oilfield similarity calculation only considers the analogy parameter values, ignoring the geological significance of the analogy parameters, resulting in large differences between the screening results an...
