Abstract

SAMMENDRAG Foreliggende oppfinnelse er en fremgangsmåte for å bestemme horisontal formasjonsskjærbølgehastighet, transversal formasjonsisotropi og effektiv loggesonde-modulus. Fremgangsmåten omfatter å bestemme en effektiv loggesonde-modulus ved å modellere loggesonden som et fluidfylt sylindrisk skall. Målte Stoneley-bølgelangsomhetsverdier blir innsamlet fra en formasjon. En horisontal formasjonsskjærbølgehastighet, Vsh, blir beregnet som en funksjon av den målte Stoneley-bølgelangsomheten og en estimert Stoneley-bølgelangsomhet, hvor den estimerte gjennomsnittlige Stoneley-bølgelangsomheten blir beregnet ved å bruke den effektive sondemodulusen. En differanse mellom den målte Stoneley-bølgelangsomheten og den estimerte Stoneley-bølgelangsomheten blir minimalisert, og den horisontale skjærbølgehastighetsverdien for den minimaliserte differansen blir matet ut. Transversal isotropi kan så beregnes som en funksjon av den bestemte Vsh og den vertikale skjærbølgehastigheten, Vsv, bestemt fra vanlige loggeteknikker
