The main parameters affecting the amount of trap resources include four categories: trap volume, oil and gas fullness, reservoir characteristics and hydrocarbon characteristics.

The volume method is mainly used for resource evaluation in the trap exploration stage.
In the trap risk probability evaluation method, the weight coefficient of accumulation factors mainly expresses the control effect of the trap accumulation factors on the effectiveness of the trap and the sum of the weight coefficients of the various accumulation factors is equal to one.
In the trap risk probability evaluation method, the weight coefficient of accumulation factors mainly expresses the control effect of the trap accumulation factors on the effectiveness of the trap and the sum of the weight coefficients of the various accumulation factors cannot be greater than one.
The risk probability evaluation method in the trap effectiveness evaluation method mainly considers the five accumulation conditions of trap quality, trap control degree, reservoir, source rock, and cap rock.
