AI Technical Summary

Problems solved by technology

The disadvantage is that the obtained data is less, it cannot solve some mechanism problems of development simulation and general problems in engineering, and requires a lot of financial and material support

However, establishing a complete high-pressure model will face the situation of high temperature and pressure, equipment scale, technical difficulty and high investment

Therefore, the currently established thermal recovery high-pressure models basically have a pressure of less than 5MPa and a temperature of less than 200°C, which is different from the actual geology or reservoir structure and cannot truly simulate the underground situation, thus causing it to be used as a reference for actual reservoir development. The value is not great
