Abstract
A correction method for a microseism interpretation fracturing fracture parameter result. The method includes classifying the communication modes of a block sampling fractured wells to be corrected according to the matching degree of micro seismic monitoring result and sand adding amount; correcting the volume coefficient of each said classified fractured well single well, and the volume correction coefficient Bv of each said fractured well is: wherein, [L5/4H]W is a calculation value of a micro seismic monitoring interpretation result; [L5/4H]T is a theoretical calculation value obtained by using field construction parameters; C, calculating the classification volume correction coefficient of each class of fractured wells according to the calculated single well volume correction coefficient of each said fractured well. The micro seismic interpretation result can be corrected in combination with the field construction parameters, so that the micro seismic monitoring data can be utilized to truly interpret the effective fracture morphology after fracturing.
