Abstract

Fremgangsmåte og anordning for posisjonstyring av en nedi-hulls aktuator (1) sitt arbeidsorgan (12) hvor aktuatoren (1) er koplet til en griper (2) og anbrakt i et borehull (8) og hvor aktuatorens (1) arbeidsorgan (12) forskyves ved hjelp av en skrue-mutterforbindelse (20, 22) som drives av en motor (24), og hvor fremgangsmåten omfatter: - å kople en giver (28) til aktuatoren (1) hvor giveren (28) er innrettet til direkte eller indirekte å kunne måle skruens (22) dreievinkel; - å kople giveren (28) til en styringenhet (30) hvor styreenheten (30) er innrettet til å kunne motta en settverdi for hvor langt arbeidsorganet (12) skal forskyves, og på grunnlag av settverdien å styre motoren (24) til å dreie i ønsket retning inntil styreenheten (30) på grunnlag av signal fra giveren (28) beregner at settverdien er oppnådd; - å stille inn en settverdi; og - å følge med på at settverdien oppnås.Method and apparatus for position control of a downhole actuator (1) its working member (12) wherein the actuator (1) is connected to a gripper (2) and arranged in a borehole (8) and wherein the actuator (1) working member (12) is displaced by means of a screw-nut connection (20, 22) driven by a motor (24), the method comprising: - connecting a encoder (28) to the actuator (1) where the encoder (28) is arranged directly or indirectly being able to measure the turning angle of the screw (22); - coupling the sensor (28) to a control unit (30) where the control unit (30) is arranged to receive a set value for how far the working member (12) is to be displaced, and on the basis of the set value to control the motor (24) to rotate in the desired direction until the control unit (30) on the basis of signal from the sensor (28) calculates that the set value is obtained; - to set a set value; and - to monitor that the set value is obtained.
