TL;DR: In this article, the authors proposed an offshore oil-gas well fracturing effect evaluation method, which comprises the following steps that S1, a constant production rate and actual measured pressure data of a stratum fluid in the periods of flowback and obtaining production after fracturing operation is obtained; S2, the constant production rates and the actual measured pressures data are processed by adopting a deconvolution algorithm, and processed pressure data is obtained, wherein the physical property parameters of the stratum comprise the effective half-fracture length xf and the average effective permeability K.
