Problems solved by technology

However, there is no indoor experimental method based on visual physical simulation for repeated measurement and real-time observation of the water absorption profile curve, which limits the oil workers' intuitive understanding of the water absorption capacity of each layer to a certain extent, so it is necessary to establish a dynamic measurement The device and method of water absorption profile provide technical support for a better understanding of the oil and gas field development process

Description

technical field [0001] The invention relates to a device for dynamically measuring a water absorption profile, a working method and an application thereof, belonging to the technical field of petrochemical industry. Background technique [0002] In the process of water flooding to develop reservoirs, often because the reservoir contains many oil layers, and the physical properties are unevenly distributed in the vertical direction, the water absorption capacity of each oil layer is different, so the water injection development effect of each layer is different. The water absorption profile of the injection well can reflect the water absorption capacity of the formation. The obtained water absorption profile data can be used to understand the vertical distribution of the injected water, predict and control the waterline advancement, monitor the water absorption capacity of the oil layer, and analyze the remaining oil distribution. Therefore, obtaining the dynamic water absorp...
