Abstract

Konvensjonell formasjonsevaluering med dobbelte ekspanderbare pakninger inkluderer trinnene med å trykksette pakningene slik at en ringformet del av borehullveggen isoleres, en eller flere prøver av formasjonsfluid samles via den isolerte del av borehullveggen, og pakningene trykkavlastes slik at bevegelse av spindelen inne i borehullet tillates. En metode og apparatur som fordelaktig anvender en eller flere av de følgende er tilveiebrakt: deformasjon av pakningene under ekspansjon begrenses ved bruk av en ringformet avstivningssammenstilling; pakningene tilbaketrekkes aktivt ved bruk av det omgivende borehulltrykk; og spindelen sentreres vesentlig mellom pakningene slik at utbuling av spindelen motvirkes.
