Physical simulation method for petroleum reservoir architecture and physical simulation device for petroleum reservoir architecture

Abstract

The invention discloses a physical simulation method for a petroleum reservoir architecture and a physical simulation device for the petroleum reservoir architecture and mainly aims to solve the problem in the prior art that methods and devices capable of effective simulation of the petroleum reservoir architecture lack. The physical simulation device is characterized by being constructed and including two parts, namely an organic glass box body and a support frame which can be rotated by 90 DEG and positioned, wherein the organic glass box body adopts a mechanism with four sides adhesively fixed and two sides movably disassembled, and a plurality of thin aluminum plates which can be discretionally bent for forming are further arranged; electrodes with adjustable testing heights are arranged at the bottom of the organic glass box body; injection and extraction system ports are arranged on the two sides of the box body; output ends of the electrodes are connected to a 24-core aviation plug through conducting wires as three-dimensional resistivity detection and monitoring ports. Based on the properties of the thin aluminum plates, various angles and radians can be achieved through the folding of the thin aluminum plates, so as to simulate the actual geographic architecture; the thin aluminum plates are pulled out after compaction; clay, vacuum silicone grease and other materials are used for sealing in a different direction before recompaction.

Description

technical field [0001] The invention relates to a laboratory simulation device and method applied in the fields of petroleum geological exploration and oil and gas field development. Background technique [0002] At present, sufficient attention has been paid to the control of remaining oil by reservoir structure at home and abroad, and corresponding well pattern adjustment and horizontal well development have been carried out for the parts that may form remaining oil according to its role, but the results are good and bad, contradictory. extremely prominent. The reason is mainly due to the limitation of the difficulty of filling the model for physical simulation, which can only slightly reflect the oil reservoir configuration at a macro level, but cannot carry out effective physical simulation through the device according to the actual reservoir configuration, resulting in the inability to pass Experimental devices are used to reveal the mechanism of the displacement char...

[0002] At present, sufficient attention has been paid to the control of remaining oil by reservoir structure at home and abroad, and corresponding well pattern adjustment and horizontal well development have been carried out for the parts that may form remaining oil according to its role, but the results are good and bad, contradictory. extremely prominent

The reason is mainly due to the limitation of the difficulty of filling the model for physical simulation, which can only slightly reflect the structure of the oil reservoir at a macro level, but cannot carry out effective physical simulation through the device according to the actual reservoir structure, resulting in the inability to pass Experimental devices are used to reveal the mechanism of the displacement characteristics of the injectant and the distribution characteristics of the remaining oil in the reservoir, so it cannot provide systematic support for revealing the reservoir structure to control the distribution of the remaining oil, and provide scientific geo-steering for tapping the potential of old oilfields and improving oil recovery
