Abstract

The invention provides a method and equipment for determining the influence weight of geological parameters on the resource quantity, and the method comprises the steps: obtaining a plurality of groups of sample data of a to-be-surveyed region, the to-be-surveyed region storing unconventional oil and gas resources, and the sample data being data of each target geological parameter used in a preset resource quantity calculation mode; calculating a resource quantity result of each group of sample data based on a preset resource quantity calculation mode and the multiple groups of sample data; performing multiple linear regression fitting processing on the resource quantity result of each group of sample data and the multiple groups of sample data to obtain a linear regression model of the resource quantity and each target geological parameter, and determining a partial regression coefficient of each target geological parameter based on the linear regression model; and based on the partial regression coefficient of each target geological parameter, determining the weight of each target geological parameter on the influence of the resource quantity. According to the method, the influence of human subjective factors can be reduced, and the purpose of improving the accuracy of the shale gas resource evaluation result is achieved.

Description

technical field [0001] The invention relates to the technical field of unconventional oil and gas resources, in particular to a method and equipment for determining the influence weight of geological parameters on resource quantities. Background technique [0002] Unconventional oil and gas refers to oil and natural gas resources that cannot be recovered under the current technical conditions, or are not economically beneficial. It generally includes tight and ultra-tight sandstone oil and gas, shale oil and gas, super-heavy (thick) oil, bituminous sandstone, coalbed methane, water-soluble gas, natural gas hydrate, etc. [0003] Taking shale gas as an example, shale gas is a natural gas resource that can be exploited in shale formations. In the early stage of exploration, explorers need to evaluate the amount of shale gas resources. Due to the uncertainty of geological variables and the heterogeneity of shale gas accumulation conditions, the uncertainty in shale gas resourc...
