【Abstract】 This paper introduces 3D High Temperature High Pressure Horizontal Well Physical Modelling System which was designed and constructed in 1996 through joint venture effrts of RIPED and TEXACO. This system is mainly used to study the mechanisms of horizontal well production technology, to provide oilfields with horizontal well technology consultant service, and to evaluate EOR process with horizontal wells and/or vertical well combination. This system is used to research non thermal oil recovery process under reservoir conditions in a 3 dimensional sand packed model with horizontal or vertical wells as injectors and/or producers. Pressure gradients is monitored by means of 100 differential pressure sensor imbedded in the sand packed model. Oil saturation distribution can be correlated by the pressure measurement of each point during the run. Its maximum working pressure is 10MPa, and maximum temperature is 120℃. The automated data acquisition and control has reduced human errors and enhanced data accuracy, also makes it possible to run long time experiments.更多还原
