Method of three-dimensional physical model of large-scale underground water sealing stone cave depot water curtain water supplementing system

Abstract

The invention relates to the oil gas storage and transportation technology field and especially relates to the method of the three-dimensional physical model of a large-scale underground water sealingstone cave depot water curtain water supplementing system. The method comprises the following steps of (1) making the device of the three-dimensional physical model of the large-scale underground water sealing stone cave depot water curtain water supplementing system; (2) changing the water injection structure of a water curtain system, measuring a water supplementing effect and water discharge,and acquiring an optimum water injection structure; and (3) through a constant speed or constant voltage feed liquid device, changing the water injection parameter of the water curtain system, measuring the water supplementing effect and the water discharge, and acquiring an optimum water injection parameter. In the invention, through a three-dimensional visual physical model, the large-scale underground water sealing stone cave depot water curtain water supplementing system can be visually simulated, and the water supplementing effect of the cave depot water supplementing system is visually known; and a control variable method is used to accurately analyze, a result is accurate and reliable, and the method has important guiding significance for mine construction designing and parameter adjustment.

Description

technical field [0001] The invention relates to the technical field of oil and gas storage and transportation, in particular to a method for a three-dimensional physical model of a water curtain water replenishment system in a large underground water-sealed cave reservoir. Background technique [0002] With the rapid development of China's economy, the demand for oil is increasing day by day. For China, carrying out strategic petroleum reserves plays a very important role in ensuring national security and ensuring the sustainable development of the national economy. The underground cavern storage has the advantages of safety, economy, high efficiency and large storage capacity, so it has been greatly developed in recent decades and is widely used in the national petroleum strategic reserve. In some areas, natural groundwater is difficult to meet the water sealing effect, and there is a problem of difficulty in natural water replenishment. In the cave reservoir, a water curt...

Problems solved by technology

Underground water-sealed caverns In some areas, the natural groundwater is difficult to meet the water-seal effect, and there is a problem of natural water replenishment. In the caverns, a water curtain system is designed to artificially replenish water. The influence of the design of the water curtain on the water replenishment effect requires a three-dimensional physical analysis. model for simulation
