Abstract
The present invention discloses a method for comprehensive evaluation of shale fracability under the geology-engineering 'double-track' system, comprising the following steps: S1: Divide the target horizontal fracturing interval into multiple sampling sections; S2: Establish the reservoir property evaluation factor of each sampling section, and calculate the geological evaluation index of the target horizontal fracturing interval according to the reservoir property evaluation factor of each sampling section; S3: Establish the brittleness factor, natural fracture factor and natural fracture opening factor of each sampling section, and then establish the engineering evaluation index of each sampling section according to these factors; S4: Calculate the engineering evaluation index of the target horizontal fracturing interval according to the engineering evaluation factor of each sampling section; S5: Evaluate the fracability of the target horizontal fracturing interval according to the geological evaluation index and the engineering evaluation index.
