Abstract
Den foreliggende oppflrmelsen tilveiebringer systemer som anvender flberoptikk tU overvåkning av nedihullsparametere og driften og tilstandene til nedihullsverktøy. I ett system plasseres fiberoptiske sensorer i brørmboringen for å gjøre distribuerte målinger for å bestemme fluidparameteme inkludert temperatur, trykk, fluidsfrønming, fluidbestanddeler og kjemiske egenskaper. Optiske spekfromefriske sensorer anvendes for å overvåke kjemiske egenskaper i brønnboringen og på overflaten for kjemiske injeksjonssystemer. Fiberoptiske sensorer benyttes for å bestemme formasjonsegenskaper inkludert resistivitet og akustiske egenskaper kompensert for temperatureffekter. Fiberoptiske sensorer brukes til å overvåke driften og tilstanden til nedihullsinnretninger inkludert elektriske nedsenkbare pumper og strønmingsstyringsinnretninger. I én utførelsesform benyttes en felles fluidledning til å overvåke nedihuUsparametere og til å drive hydraulisk opererte innretninger. Fiberoptiske sensorer anvendes også til å overvåke den fysiske tilstanden til kraftledninger som tilfører høy elektrisk kraft til nedihullsutstyr. En lyscelle anbrakt nedihulls anvendes til å generere elektrisk effekt i brørmboringen, som anvendes tU å lade batterier.The present invention provides systems utilizing fiber optics for monitoring downhole parameters and the operation and conditions of downhole tools. In one system, fiber optic sensors are placed in the wellbore to make distributed measurements to determine the fluid parameters including temperature, pressure, fluid deposition, fluid constituents, and chemical properties. Optical spectrometric sensors are used to monitor chemical properties in the wellbore and on the surface of chemical injection systems. Fiber optic sensors are used to determine formation properties including resistivity and acoustic properties compensated for temperature effects. Fiber optic sensors are used to monitor the operation and condition of downhole devices including electric submersible pumps and flow control devices. In one embodiment, a common fluid conduit is used to monitor downhole parameters and to operate hydraulically operated devices. Fiber optic sensors are also used to monitor the physical state of power lines that supply high electrical power to downhole equipment. A light cell located downhole is used to generate electrical power in the wellbore, which is used to charge batteries.

I ett system plasseres fiberoptiske sensorer i brønnboringen for å gjøre distribuerte målinger for å bestemme fluidparameterne inkludert temperatur, trykk, fluidstrømning, fluidbestanddeler og kjemiske egenskaper.
