Abstract
Fremgangsmåten omfatter bruk av en anordning (5) for utsendelse av signaler og minst to mottaker- enheter (8, 10) anordnet på to forskjellige steder langs bronnutstyret (2). Hver av mottaker- anordningene danner et bilde eller en signatur av veggpartiene som passerer forbi. Bildene som dannes av enheten (8) som befinner seg på det laveste nivå i det tilfellet hvor utstyret (2) blir senket, blir lagret det nødvendige tidsrom for at den andre enheten (10) i utstyret som beveger seg nedover, kan motta signalene som kommer fra det samme veggparti for også å danne et bilde. En sammenlignings- operasjon (for eksempel en korrelasjon) av bildene som henholdsvis kommer fra de to enhetene, gj«r det mulig å identifisere det samme veggparti som har frembrakt de to sammenlignede bilder. Tidsinter- vallet mellom dannelsen av de to tilsvarende bildene, blir målt og fremdriftshastigheten blir beregnet, Anvendelsesområdet er for måling av den virkelige fremdriftshastigheten til brønnutstyr eller en målesonde.The method comprises the use of a device (5) for transmitting signals and at least two receiver units (8, 10) arranged at two different locations along the source equipment (2). Each of the receiving devices forms an image or signature of the wall portions that pass by. The images formed by the unit (8) which are at the lowest level in the case where the equipment (2) is lowered are stored for the required period of time for the other unit (10) in the equipment moving downwards to receive the signals which coming from the same wall section to form an image as well. A comparison operation (for example, a correlation) of the images coming from the two units, respectively, makes it possible to identify the same wall part that produced the two compared images. The time interval between the formation of the two corresponding images is measured and the progress rate is calculated. The area of application is for measuring the actual progress rate of well equipment or a measuring probe.
