1. Overview
The oilfield uses artificially prepared acid to acidize the formation to dissolve the blockages in the rock pores and fissures, and to improve or restore the permeability of the pores and fissures of the formation. Acidizing is a common means to improve the recovery rate, and it is an effective technical measure to increase the production of oil and gas wells and injection wells.
This equipment is made of Hastelloy alloy material, which effectively ensures the quality and service life of the instrument. This equipment can be used to do core liquid permeability measurement, reservoir sensitivity evaluation experiment, oil production process research, acidification, fracturing, water plugging, adjustment of injection and production profile and other tests. Research on enhanced oil recovery, secondary and tertiary oil recovery after acidification.
