APPARATUS FOR STUDY OF FILTRATION PROPERTIES OF PRODUCTIVE BEDS AT OPENING THOSE BY PERFORATION

摘要

Apparatus for study of filtration properties of productive beds at opening those by perforation includes core holder with target and inlet piston with single-charge perforator, system for pumping-through working agents and for sampling. To increase reliability and accuracy of results of investigations and to broaden the functional possibility of the apparatus is additionally has unit for unloading with removal of excess pressure of powder gases, and the inlet piston at the side of cumulative jet outlet is equipped with central axial channel and at least two radial channels, those are hydraulically connected to the axial channel, the system of the working agents pumping-through and the unit for unloading with removal of excess pressure of powder gases.
