The invention aims to provide a tight oil and gas reservoir post-pressing evaluation method, which comprises the following steps: carrying out a test on a tight core, observing and recording fracture network parameters, generating a sample data set, carrying out algorithm analysis, screening out fracture network form master control influence parameters, matching a proper fracture expansion criterion, and carrying out mathematical description and discrete solution on fracture network form change. And converting the yield of a single well after fracturing by using the established well testing model, and evaluating the effect of the compact oil and gas reservoir after fracturing. The new post-fracturing evaluation method is established on the basis of reality, the algorithm is reasonably applied, field use is facilitated, the calculation precision is high, and the method is beneficial to efficient development of tight oil and gas. 本发明旨在提供一种致密油气藏压后评估方法，以致密岩心开展试验，观察记录缝网参数，生成样本数据集，经算法分析，筛出缝网形态主控影响参数，匹配合适的裂缝扩展准则，对缝网
