Abstract: This paper presents a new electrical analogous equipment,which has solved the problem of a compacted zone around the perforation and drilling damages around the wellbore. Under negative pressure there is no blocking up by perforation debris. The equipment is designed for the parameter range under negative pressure. The experiment was arranged and conducted with the application of mathematical statistics in terms of nine parameters: perforation penetration, perforation diameter, shot density, compaction thickness, compaction damage, perforation phasing peoforation model, drilling damage and damage depth.The advantage of this technique is less times of tests and simple date treatment.The regression equation can predict the effects of the nine parameters upon well production.The results derived from permeability theory are applicable to any homogeneous reservoir.
