Description

Technical Field

[0001] The utility model relates to the technical field of petroleum exploitation simulation models, in particular to a petroleum well-to-well connectivity simulation model. Background Art

[0002] Well-to-well connectivity refers to the connectivity between different wells in the oil field in terms of geological structure. This connectivity can affect the production efficiency of the oil field and the flow of oil. If the connectivity between oil wells is good, the production pressure can be transmitted to other wells through the connected strata, thereby improving the production efficiency. On the contrary, if the connectivity is poor, the production pressure may not be effectively transmitted, resulting in reduced production efficiency.

[0003] In oilfield development, it is very important to understand the connectivity between wells. Existing technologies are all based on injection-production balance analysis based on prediction models, quantitative analysis of inter-well flow field relationships based on digital simulation models, and three-dimensional digital simulation of reservoir flow fields. They are processed and displayed by computers, etc. There is no simulation model for displaying the connectivity between oil wells. To this end, we propose a simulation model for connectivity between oil wells. Utility Model Content
