Abstract

The invention discloses a fractured-vuggy oil reservoir physical model device, and a device for evaluating a runner adjustment synergistic agent. The fractured-vuggy oil reservoir physical model device comprises a support, at least one partition plate and a plurality of karst cave models, the partition plate is arranged on the support, the karst cave models are detachably arranged on the partition plate, The karst cave models are connected through connecting pipes, and the connecting pipes are used for simulating fractures of the fractured-vuggy oil reservoir. The devices can be used for simulating the distribution of the remaining oil of the fractured-vuggy reservoir, and can be used for evaluating the adaptability of various flow channel adjusting synergists. The model adopts an assembling and splicing mode, various types of remaining oil distribution can be simulated, and the fracture-cavity position can be adjusted according to the actual field requirement. The model can be used for effectively evaluating the adaptability of systems such as a low-density displacement system, a karst cave oil-water partition agent and a temporary plugging chemical bridge plug to the fracture-vug type oil reservoir, and has important significance for further analyzing the synergistic mechanism of various flow channel adjusting synergistic agents.

Description

technical field [0001] The invention relates to the technical field of a fracture-cave oil reservoir physical model device, in particular to a fracture-cavity oil reservoir physical model device and a device for evaluating a synergistic agent for flow channel adjustment. Background technique [0002] In order to study the law of remaining oil in carbonate reservoirs of fracture-cavity reservoirs, physical models are often used at home and abroad to simulate the actual geological conditions, and the actual effect of channel adjustment synergists is evaluated by using the physical model. Common physical models of fractured-cavity reservoirs at home and abroad mostly use marble etching models formed at one time, or similar plexiglass models for simulation. This type of model is bulky and difficult to form. After local damage, the model is completely damaged and cannot be repaired. After damage, it is difficult for the remanufactured simulation to be completely consistent with ...
