IMPACT EXCAVATION SYSTEM AND METHOD |
摘要 |
<p>A method and system for excavating a subterranean formation using a fluid comprising pumping the fluid through at least one nozzle such that a velocity of the fluid when exiting the nozzle is greater than a velocity of the fluid entering the nozzle. A plurality of solid material impactors are introduced into the fluid and circulated with the fluid through the nozzle. A substantial portion by weight of the solid material impactors has a mean diameter of equal to or less than approximately 0.100 inches. The fluid is pumped at a pressure level and a flow rate level sufficient to satisfy an impactor mass-velocity relationship wherein a substantial portion by weight of the solid material impactors has a minimum kinetic energy of approximately 0.075 Ft Lbs when exiting the nozzle. The substantial portion by weight of solid material impactors exit the nozzle and contact the formation.</p> |
