Shock wave de-plugging etc.) effect assessment experiment face heavy problem.Although 1, artificial core can permeability, porosity and
Actual reservoir is simulated in terms of water-sensitive well, but the mechanical property of artificial core can not simulate actual reservoir.And physics de-plugging
The technical principle of method is similar, is to be pressed near wellbore zone and stratum to dredge fluid course, improves in-place permeability,
Release the blocking near wellbore zone stratum.Artificial core mechanical performance index is limited to lower than formation core, using the artificial of pollution
Rock core evaluates physics plugging removal effect, is more also easy to produce crack, increases hole, can not objective appraisal physical method plugging removal effect.Back-up sand
Model similarly can not also objectively evaluate plugging removal effect.2, the method for evaluating controllable shock wave plugging removal effect be mainly numerical simulation and
Two kinds of simulating lab test.Method for numerical simulation is theoretical still incomplete in terms of intermittent repeat function, effect differentiation, for
Shock wave de-plugging simulation needs Binding experiment to be corrected.And simulating lab test mostly uses small energy de-plugging parameter to certain at present
One pollution rock sample carries out single direction de-plugging experiment, although it can be concluded that test result verifies this kind of method to carry out to reservoir
De-plugging.But due in practical pit shaft, shock wave from after generating device sending, radially successively by well liquid within the cartridge, screen casing,
Casing causes just act on reservoir after energy attenuation, simulating lab test can not accurate evaluation shock wave cross screen casing, casing energy
Amount decaying after plugging removal effect, can not assess impact energy same radially different orientation Energy distribution situation, can not evaluate
Shock wave radially to the de-plugging function and effect of different direction rock core, can not assess impact energy along axial effective de-plugging away from
From, be unable to scientific utilization experimental result and instruct different type to block preferred cumulative bullet and formulate operation number of shocks.
