Problems solved by technology

At present, many related physical simulation devices have been designed for the migration and accumulation of oil and gas and the process of water flooding oil, but the existing technical means are mostly single-function research, only for the content of a certain aspect of oil and gas accumulation or oil and gas development. , it is impossible to realize systematic multifunctional experiments, and the existing technical means are relatively single in the experimental model, weak in the ability to characterize complex reservoir heterogeneity, not advanced enough in the experimental configuration, and lack of scientific real-time data collection and analysis Functionality, rough experimental results, low degree of automation

Abstract

The invention provides a comprehensive simulation experiment device for reservoir heterogeneity, and belongs to simulation experiment devices in the fields of petroleum geology and exploitation geology. The problems of oversimplified simulated geologic models, single simulation function and simulation separation of reservoir forming and exploitation are mainly solved. The comprehensive simulation experiment device is characterized in that integrated simulation of petroleum reservoir forming and exploitation is realized, and especially the reservoir heterogeneity has influences on petroleum reservoir forming, water-flooding extraction and formation and distribution of remaining petroleum. The device mainly comprises a fluid injection system, a geologic model building system and an experiment collection and control system. Connecting devices are arranged inside each system and among the systems. The experiment device is comprehensive in system, high in comprehensiveness, flexible in design, reasonable in structure, convenient to operate and high in automation degree; with the experiment device, fluid motion of the petroleum reservoir can be directly observed and changes of fluids at the entire petroleum reservoir can also be monitored, so that the experiment device can have various experiment functions and wide application.

Description

Technical field: [0001] The invention relates to the fields of petroleum geology and development geology, in particular to comprehensively simulate the influence of reservoir heterogeneity on oil and gas accumulation, water injection development, water flooding oil and the formation and distribution of remaining oil. Background technique: [0002] Reservoir heterogeneity is an important research content in the field of petroleum geology and development geology. Reservoir heterogeneity plays an important role in oil and gas accumulation, production and development, water flooding oil, formation and distribution of remaining oil, etc. influences. In the process of oil and gas exploration and development, different sandstone oil and gas reservoirs with similar oil source conditions and structural background have very different oil and gas properties. The reason is likely to be caused by different reservoir heterogeneities. The secondary migration and accumulation process in th...
