Procedure and production pipe for production of oil or gas from an oil or gas reservoir

摘要

Method and production pipe for production of oil or gas from a well in an oil and/or gas reservoir, or injection of fluids into a well in an oil and/or gas reservoir, comprising a production pipe (1) with a lower drainage pipe (2). The drainage pipe (2) is divided into sections (3) with one or more inflow-restriction devices (4) which control the flow of oil or gas from the reservoir into the drainage pipe on the basis of calculated loss of friction pressure along the drainage pipe, the reservoir's calculated productivity profile, and the calculated inflow of gas or water.
