Abstract

The invention provides a shale gas single well geology comprehensive evaluation method. The method comprises the steps that 1 the tight sandstone gas resource amount is calculated through an analogy method, a volume method and a basin simulation method; 2 weighted average is carried out on the resource quantity calculated by the analogy method, the volume method and the basin simulation method byadopting a fiert method to obtain a tight sandstone gas resource quantity; 3 transverse sealing performance analysis of the shale gas single well fault is conducted; and 4 lateral sealing performanceanalysis of the shale gas single well fault is carried out.

Description

technical field [0001] The invention relates to the technical field of geophysical exploration, in particular to a comprehensive geological evaluation method for a single well of shale gas. Background technique [0002] Shale gas geological evaluation, especially single well geological comprehensive evaluation is very important for the evaluation of unconventional resources. It can establish unconventional oil and gas resources evaluation and selection evaluation methods and standards, obtain the potential and distribution of unconventional oil and gas resources, and clarify unconventional oil and gas resources. Favorable exploration zones provide a very important basis for the deployment of oilfield exploration and development. [0003] However, it is currently impossible to find parameters that can typically represent the comprehensive geological evaluation of a single well of shale gas, and there is no reasonable means to obtain accurate test data of a single well of shal...
