According to problems of small perforated diameter, low penetrate force for perforator used in wells of low porosity and permeability, a new large-aperture ultra-deep penetrating perforator has been designed through simulation and experimental design parameters. On the premise of guarantee the perforation depth enough, the biggest perforation aperture than similar perforator increases more than 15% which facilitates the proper evaluation of oil and gas reservoirs and improve well productivity, and has an extremely important significance in developing reservoirs of low porosity and low permeability. ©, 2015, Well Testing.
