Abstract
Metode for styring av fluidstrømmen fra en brønn i forbindelse med produksjon av olje og gass fra formasjoner under jordoverflaten, innbefattende et produksjonsrør i tilknytning til brønnen som er forsynt med en choke for styring av fluidstrømmen. Det tas utgangspunkt i at væskeraten varierer lite i forhold til gassen (rateavhengig GLR), idet en regulator (FC) som styrer choken (1) og som er anordnet i tilknytning til produksjonsrøret (2) reguleres på basis av estimering av gassraten i brønnfluidstrømmen med utgangspunkt i et trykkfall AP som måles over en restriksjon i røret. Gassraten for fluidet kan hensiktsmessig estimeres ved anvendelse av algoritmen: qge = a· f(z)·v(?P + b)·Puc hvo r : qge Gassrateestimat a Justeringsfaktor b J usteringsfaktor (ofte for feil i en trykktransmitter) f(z) Kompenseringsfunksjon for restriksjon (for eks. ventilkarakteristikk) z Variabel i kompenseringsledd (for eksempel ventilposisjon) ?P Differansetrykk over restriksjon Puc Trykk oppst røms restriksjon som kompenserer for endringer i tetthet.A method for controlling the fluid flow from a well in connection with the production of oil and gas from underground ground formations, including a production tube adjacent to the well provided with a choke for controlling the fluid flow. It is assumed that the liquid rate varies little with respect to the gas (rate dependent GLR), as a regulator (FC) which controls the choke (1) and which is arranged in connection with the production pipe (2) is regulated on the basis of estimation of the gas rate in the well fluid flow with starting from a pressure drop AP measured over a constraint in the pipe. The gas rate of the fluid can conveniently be estimated using the algorithm: qge = a · f (z) · v (? P + b) · Puc where: qge Gas rate estimate a Adjustment factor b Adjustment factor (often for errors in a pressure transmitter) f (z ) Restriction compensation function (for example valve characteristics) z Variable in compensation link (for example valve position)? P Differential pressure over restriction Puc Pressure upstream restriction which compensates for changes in density.
