A new hybrid flooding experiment/test simulation method

Abstract

The invention discloses a novel combination flooding oil flooding experiment / test simulating method. The method comprises the steps that 1, a set of three-dimensional core models is manufactured in combination with the oil reservoir condition, a set of complete water flooding process oil flooding test and combination flooding process oil flooding test is completed on each model in sequence, and it is equivalent that minitype field tests are completed under the oil reservoir condition; 2, equivalent fitting of the oil flooding tests and the minitype field tests under the field oil reservoir condition is achieved through a numerical simulation study means, and a digital reservoir geology model platform including water flooding information and combination flooding information is built; and 3, content study is carried out on the field tests on the digital reservoir geology model platform through digital oil flooding test study. According to the method, the workload of the combination flooding indoor oil flooding test can be greatly reduced, optimized oil flooding scheme design of an oil reservoir which has combination flooding potential and is not subjected to an oil flooding test can be completed on the platform, and the quality of the field oil flooding test is improved.

Description

technical field [0001] The invention relates to an experiment / experimental digital simulation method for the application of tertiary oil recovery technology in oilfields, in particular to an oilfield triple compound flooding indoor oil displacement experiment and an on-site oil displacement scheme optimization design research method. Background technique [0002] The ASP flooding technology is an important new technology in the field of oil field tertiary oil recovery technology, and it is still in the field test and research stage at home and abroad. The main research method and process of this technology are as follows: firstly, the oil displacement system is selected through laboratory experiments, and then the oil displacement effects of different oil displacement schemes are studied through core oil displacement experiments; Based on the conditions of the reservoir model, the simulation calculation optimizes the design of the field oil displacement plan; on the basis of...

Problems solved by technology

Due to a series of technical difficulties in the three-dimensional core flooding experiment and the difficulty in precise core manufacturing, it is difficult to make comparable repeated experiments, the cycle of the oil flooding experiment is long, and the research work needs to be based on a large number of experimental data results, which is even more critical The problem is that the "equivalent relationship" between the indoor core oil displacement experiment and the mine field test under the reservoir conditions has not been determined, and the results of the indoor oil displacement experiment can only provide qualitative reference data, which makes the design of numerical simulation schemes also become a problem.
