An Autonomous Electric Logger for Hydraulic Fracturing Process
Downhole test data for hydraulic fracturing process is an important foundation of fracturing evaIuation and technique improving．However，data acquiring and recording of fracturing process by downhole electric logger,which has a limited memory and n pre·configuring work programme according to a fracturing project，may Iose many valuable records due to the difierence between this programme and reaI fracturing operation process．In this paper,the pressure CHI ve and jts features of normaI fracturing process has been analvzed．A method to distinguish distinct stages Of fracturing process has been proposed by a simple Iogic estimating technique based on pressure and its gradient． An autonomously recording strategy has been given which can distinguish cruciaI stage and record data iu a shorter period than normal．And a test under Iaboratory condition indicated the design was efficaciously．
