OPTIMIZATION OF RESERVOIR, WELL AND SURFACE NETWORK SYSTEMS

摘要

A method and associated apparatus continuously optimizes reservoir, well and surface network systems by using monitoring data and downhole control device s to continuously change the position of a downhole intelligent control valve (ICV) (12) until a set of characteristics associated with the "actual" monitored data is approximately equal to, or is not significantly different than, a set of characteristics associated with "target" data that is provide d by a reservoir simulator (32). A control pulse (18) having a predetermined signature is transmitted downhole thereby changing a position of the ICV. In response, a sensor (14) generates signals representing "actual" monitoring data. A simulator (32) which models a reservoir layer provides "target" data . A computer apparatus (30) receives the "actual" data and the "target" data and, when the "actual" data is not approximately equal to the "target" data, the computer apparatus (30) executes a "monitoring and control process" program code which changes the predetermined signature of the control pulse to a second and different predetermined signature. A new pulse having the secon d predetermined signature is transmitted downhole and the above process repeat s until the "actual" data received by the computer apparatus (30) is approximately equal tothe "target" data.
