METHOD FOR PREDICTION OF BIOCLOGGING IN UNDERGROUND STORAGE CAVERN

摘要

1. TECHNICAL FIELD OF THE INVENTION;Bioclogging Prediction Method for Maintaining Airtightness of Underground Oil Storage Cavity.;2. The technical problem to be solved by the invention;To prevent the leakage of gas and to improve the efficiency of joint operation monitoring by suggesting solutions to bacterial growth / behavior problems, which are reported as obstacles to maintaining the confidentiality of oil storage jointly.;3. Summary of Solution to Invention;Reliability by quantitatively calculating substrate concentration, biomass / biofilm thickness, void reduction rate and permeability reduction rate quantitatively by inputting initial values into bioclogging prediction numerical model from rock survey, construction data and operation data and some assumptions Predict bioclogging. In addition, by checking the permeability of the medium, it is possible to grasp the surrounding conditions of the oil underground storage cavity and to perform economic and efficient confidentiality maintenance.;4. Important uses of the invention;Used for oil underground storage joint.
