Abstract

Et tidligevalueringssystem for bruk i et foret borehull (12) er frembragt. Anordningen (10) omfatter en verktøystreng (18) med en perforeringskanon (20) på den nedre enden av denne. Verktoystrengen (18) omfatter også en pakning (24), en reguleringsventil (26), en prøvetaker (28) og en lokaliseringsanordning (36). Når anordningen (10) kjøres inn i borehullet (14), benyttes lokaliseringsanordningen (36) for å lokalisere verktøysrrengen (18) i forhold til formasjonen (16). En andre reguleringsventil (44) kan anbringes over prervetakeren (28) slik at fluid kan pumpes ned verktøystrengen (18) og tilbake inn i formasjonen (16) når reguleringsventilen (44) er åpnet. Ved operasjon, avfyres perforeringskanonen (20) etter at pakningen (24) er satt, slik at fluid i utgangs- punktet strømmer inn i den brukte perforeringskanonen (20), som da fungerer som et utjevningskammer. Deretter strømmes en fluidprøve inn i prøvetakeren (28).An early evaluation system for use in a lined borehole (12) is provided. The device (10) comprises a tool string (18) with a perforating gun (20) at the lower end thereof. The tool string (18) also includes a gasket (24), a control valve (26), a sampler (28) and a locating device (36). When the device (10) is driven into the borehole (14), the location device (36) is used to locate the tool string (18) relative to the formation (16). A second regulating valve (44) can be placed over the preamplifier (28) so that fluid can be pumped down the tool string (18) and back into the formation (16) when the regulating valve (44) is opened. In operation, the perforation gun (20) is fired after the gasket (24) is set so that fluid initially flows into the used perforation gun (20), which then acts as a balancing chamber. Then, a fluid sample flows into the sampler (28).
