Seismic physical reservoir model and preparation method and application thereof

Abstract

The invention discloses a seismic physical reservoir model and a preparation method and the application thereof. The model is composed of cement, lime, quartz sand, water, blanc fixe or kieselguhr or lime and the like. Property parameters of the model are adjustable in ranges that the propagation speed is 1800-4000m/s, the porosity is 8-40% and amplitude is 60-210. The preparation method includes: 1, putting each experimental material composition of the seismic physical reservoir model into a stirring implement, stirring, and filling into a mould after well stirring; 2, compacting and debubbling; and 3, forming and demoulding. The seismic physical reservoir model can be constructed by means of the similarity principle according to different test objectives and requirements to simulate practical geologic structures, and the seismic physical reservoir model can be used for researches on seismic wave fields and other purposes and provide objective basis for verification of novel methods and theories in oil gas exploration and development.

AI Technical Summary

Benefits of technology

The inventors have developed an improved method called Seismics Physique (SP) that can accurately simulate realistic structures such as underground formations or faults within rocks during drilling operations. This allows scientists studying these processes better understanding how they are working together more efficiently than before developing their own models.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the accuracy and efficiency of studying groundwater flow dynamics (GWD), specifically the use of new types of mathematical modelling techniques like finite element analysis (FE). Current numerical simulation tools lack sufficient detail about the spatial distribution of sedimentary rocks within large sections of faulty layers of soil and water resources. There is currently only a small number of available reserver soundings and sonar acquisition tests conducted during drilling operations. These testing involve expensive equipment and laborious procedures. Additionally, there exists a challenge related to accurately predicting fluid paths in subterranean formations when they contain multiple phases of hydrocarbon accumulations called shale hydrons.
