Abstract

Enmåling-under-boring/logging-under-boring- slampulsatoråpning for å redusere erosjon på uttømningssiden av dysen har en oppstrømsledning, en plugg montert i oppstiømsledningen på resiprok måte med hensyn til dysen, idet dysen er knyttet til oppstiømsledningen som har en strømnings- begrensningsåpning og en uttømningsside, og en nedstiømsledning som er knyttet til uttømmingssiden av dysen har en irmerdiametervegg. Stiømningsbegrensningsåpningen har et senterhull som er plugget av pluggen når pluggen beveges frem til en irmgrepsposisjon, og aksielle spor i ett med og fjerntliggende fra senterhullet. Uttømmingssiden av dysen har en glatt overgangskonisitet fra senterhullet mot irmerdiameterveggen i ^emtliggende områder (som utelukker områder av de aksielle spor).
