Description

technical field [0001] The invention relates to an intelligent oil field simulation experiment system and a working method, belonging to the field of experimental equipment for oil exploitation. Background technique [0002] In the early 21st century, the development of the world's petroleum industry has entered its middle age. Most oil and gas fields in China are in the middle and late stages of development. In addition, with the rapid economic growth, people's demand and consumption of oil resources are gradually increasing. Therefore, both at home and abroad are currently facing the problem of optimizing and maximizing the economic value of underground oil and gas resources development. [0003] How to further improve the recovery rate of mature oilfields and new oilfields, increase crude oil production, and how to further improve the overall operation and management level of oil reservoirs in their life cycle have brought new and huge challenges to petroleum workers. I...
