Embodiment 1

[0093] The main technical contents of the annual increment forecast method for oil and gas reserves include:

[0094] One is to use basin types, target types, etc. as the classification basis, and to explore the relationship between the exploration workload, the success rate of exploration wells and the reserves, and to solve the problem that the reserves report does not correspond to the time of the exploration workload, so as to determine Reserves and workload actual parameter types for forecast equations;

[0095] The second is to select the sample data of annual reserves and annual workload according to the annual time series that reflects the characteristics of the exploration stage, and based on the principle of the best correlation, establish the basic equation for the relationship between annual reserves and workload, and the coefficients of the equation are related to the geological static data of the exploration unit Related to exploration dynamic data;

[0096] The...

Abstract

The embodiment of the invention discloses a method for predicting annual increment of oil and gas reserves and electronic equipment. The oil and gas reserve annual incremental prediction method comprises the following steps: determining reserve and workload parameter types; on the basis of the determined parameter types, annual reserve and annual workload sample data are selected, an annual reserve and workload relation basic equation is established, an annual equation is obtained, and coefficients of the annual equation are related to geological static data and exploration dynamic data of the exploration unit; based on the exploration dynamic parameters in the sample data, analyzing the correlation between each coefficient of the annual equation and the exploration dynamic parameters, and respectively establishing a relation equation between each coefficient of the annual equation and the exploration dynamic parameters; constructing an oil and gas reserve annual increment prediction equation based on the annual equation and the relation equation; and predicting the annual increment of the oil and gas reserves based on the annual increment prediction equation of the oil and gas reserves. The purposes of comprehensively considering factors and improving prediction result precision and credibility are achieved.

Description

technical field [0001] The invention belongs to the technical field of petroleum and natural gas exploration, and more specifically relates to a method for predicting annual increment of oil and gas reserves and electronic equipment. Background technique [0002] There are many methods for predicting the growth trend of oil and gas reserves. The main foreign methods include multi-cycle Hubbert model based on Hubbert model; Weibull model based on probability theory and statistical theory, logarithmic normal distribution model, reservoir scale sequence method, etc.; And a mathematical model for predicting dynamic fitting of historical data, etc. These methods can make rough trend predictions, but the accuracy of quantitative predictions is not high. Domestic research results in recent years, such as Weng's model, oilfield scale sequence method, Hu Chenzhang (HCZ) model, Gomperz model, etc., are mostly based on the digestion and absorption of foreign mature methods or improve...
