The Reservoir Adaptability Study Of Multi-component Thermal Fluid Development

The multiple-component thermal fluid production is a new technology of thermal recovery, it doubles as a steam injection thermal recovery, CO2 and N2 increased technical characteristics of the oil, but the multiple-component thermal fluid extraction technology is a complex systems engineering, and part of the oil field oil reservoir developed by the multiple-component thermal fluid production technology appeared invalid phenomenon. So it is necessary to establish a reservoir screening criteria of multiple-component thermal fluid development.Based on the overview of the multiple-component thermal fluid are analyzed, equipment and performance parameters, studied how the each component in the multiple-component thermal fluid to improve oil recovery. Then with reference to our country typical heavy oil reservoir geological fluid parameters conceptual geological model is established, by using reservoir numerical simulation to study the geological fluid parameters on the influence law of effect of multiple-component thermal fluid stimulation, and analyzes the influence of each parameter sensitivity; Through the establishment of the multiple-component thermal fluid and the limit of economic indicators, seven geological fluid parameters economic limit such as reservoir thickness, oil viscosity,were given, and then set up the multiple-component thermal fluid throughput development reservoir screening standard, and combined with field case from positive and negative aspects to verify the multiple-component thermal fluid throughput development reservoir screening of the accuracy of the standard.After studying the multiple-component thermal fluid stimulation adaptability, by establishing the geological concept model, and using reservoir numerical simulation method for the multiple-component thermal fluid drive injection-production parameters are optimized; Considering the balance of payments, to establish the limit of the multiple thermal fluid drive economic indicators, and combined with the results of numerical simulation to determine the seven major geological fluid parameters’ economic limit, then set up the reservoir screening standard table of multiple-component thermal fluid drive. At last, combined the example verifies the multiple-component thermal fluid drive reservoir screening of the accuracy of the standard table.Finally, using the theory of fuzzy mathematics knowledge and set up fuzzy comprehensive evaluation model of diversified development of multiple-component thermal fluid, and the accuracy of the model is verified by field examples and practical, make up for the use of subjective cognition for qualitative estimate the multiple-component thermal fluid insufficient development of reservoir screening results.This article research results to better understand the geological fluid, and the effects of parameters on the multiple-component thermal fluid development law provides the theoretical basis, at the same time for the development of oil field actual use of the multiple-component thermal fluid reservoir is of important guiding significance.
