The invention provides a fracturing well selection and layer selection method based on a process. The fracturing well selection and layer selection method comprises the following steps: analyzing factors influencing well selection and layer selection, and establishing a well selection and layer selection database; carrying out fracturing well data comprehensive query to realize fracturing well data query and multi-stage screening; carrying out fracturing influence factor analysis to realize influence factor correlation analysis and statistical analysis; establishing a fracturing effect evaluation plot to realize rapid qualitative prediction of the fracturing effect; achieving comprehensive evaluation of the fracturing effect by combining geological achievements and process effects; carrying out quantitative prediction on the fracturing effect by utilizing a quantitative prediction algorithm; and establishing an improved well selection and layer selection principle conforming to different geologic body characteristics. Based on a database system, the fracturing well selection and layer selection method tightly combines geology with a process, provides a cross-professional analysis and evaluation tool, and comprehensively applies statistical analysis, rapid pre-judgment and quantitative prediction methods, thus improving the process pertinence and the success rate, enables the mature technology to be programmed, realizes resource sharing, and provides important technical support for single-well production increase decision and process optimization.
