Abstract
Fremgangsmåte og anordning for å foreta målinger og/eller inngrep i en brønn soa omfatter en første sone hvor en hydraulisk koBqprimering, såsom en trykkfrakturering finner sted, og en andre sone bvor målinger og/eller inngrep utføres, hvilken koaqptrimer- ingssone gjennom et rør (6) kommuniserer ned bydratiliske trykk- midler. idet rørets (6) nedre ende omfatter en av ett eller flere måleinstnuiienter bestående enhet som er forbvindet med overflaten via en kabel (17) som er plassert i røret (6) og er mekanisk løsbar fra røret ved bjelp av en elastisk forbindelse, såsom en forbindelseskabel (13). Freagangsmåten er i første rekke kaoralcterisert ved at ved et rørpunkt ner fraktureringssonen ' reguleres enhver fraktureringsfluldstrømnlng son kommer fra eller strømmer til fraktureringssonen ved bjelp av regulerlngsmidler (12a, 12b) som i det minste delvis styres ved hjelp av kabelen (17) fra overflaten, hvilke reguleringsnidler er beliggende på et høyere nivå enn enheten. Anordningen er i første rekke karitk- terisert ved at den omfatter midler (12a, 12b) som styrer fluidsirkulasjonen mellom røret (6) og komprimeringssonen (la) og at kabelen er innrettet til å regulere midlene (12a, 12b) fra overflaten. Oppfinnelsen er scrlig anvendbar for målinger og/eller Inngrep som utføres under trykkfrakturering av brønner son er boret 1 grunnen.A method and apparatus for making measurements and / or interventions in a well so comprises a first zone where a hydraulic co-priming, such as a pressure fracture, takes place, and a second zone where measurements and / or interventions are performed, which co-trim zone through a pipe ( 6) communicates down byrathilic print media. the lower end of the tube (6) comprising a unit (s) comprising one or more measuring devices which are connected to the surface via a cable (17) located in the tube (6) and mechanically detachable from the tube by the aid of an elastic connection, such as a connecting cable (13). The process is primarily coralized by regulating, at a pipe point down the fracture zone, any fracture flux flow zone coming from or flowing to the fracture zone by means of control means (12a, 12b) controlled at least in part by the cable (17) from the surface. regulators are located at a higher level than the unit. The device is primarily characterized in that it comprises means (12a, 12b) which control the fluid circulation between the tube (6) and the compression zone (1a) and that the cable is adapted to regulate the means (12a, 12b) from the surface. The invention is particularly applicable to measurements and / or interventions performed during pressure fracturing of wells drilled into the ground.
