The invention relates to a test system, in particular to a horizontal well steam injection ground simulation test system comprising a water tank. A centrifugal pump, a steam limiting distributor, a data collector and a master are sequentially connected to the lower portion of the water tank. The centrifugal pump is further provided with a control cabinet. The steam limiting distributor is provided with a plurality of sensors all connected to the data collector. The horizontal well steam injection ground simulation test system is simple in structure and well practical.
Description
technical field [0001] The invention relates to an experiment system, in particular to a ground simulation experiment system for horizontal well steam injection. Background technique [0002] In the process of steam injection in horizontal wells of heavy oil reservoirs, affected by factors such as reservoir physical properties, formation pressure, and wellbore pressure drop, the conventional steam injection method cannot ensure the uniform distribution of steam injection at different positions along the wellbore direction, resulting in some The reservoir cannot be heated and produced effectively, and the production of the oil well is low. Therefore, how to control the steam injection rate of each layer and improve the steam absorption profile of the reservoir is of great significance for improving the recovery of heavy oil reservoirs. The multi-point steam injection process is based on the characteristics of long steam injection section and differences in reservoir physical...
