水驱速度对束缚型和油膜型剩余油动用的影响理论及实验
THEORIES AND EXPERIMENTS OF THE WATER-FLOODING-RATE INFLUENCES ON THE DEVELOPMENT OF THE CAPTURED AND FILM TYPE REMAINED OIL
摘要
Abstract
In order to explore the mechanism of enhancing the remained oil recovery by increasing the water injection rate,the theoretical and experimental researches on the influences of the increased water injection rate on the remained oil were conducted.With the help of the mechanical principle of the oil flooded in the pore by the water,the influences of the water injection rate were analyzed on the movements of the remained oil and film-type remained oil captured in the pore,the new method of quantitatively determining the remained oil was established.The studies show that by means of increasing the water injection rate,the Jamin effect of the captured-type remained oil can be overcome.In a word,increasing the rate,water flow and the shear stress among the oil film is the effective approaches of enhancing the developed degree of the captured-type and film-type remained oil.The experimental results show that when the water injection rate increasing from 0.05 mL/min to 0.5 mL/min,the remained oil saturation decreases from 38.2％ to 18.8％ and the oil recovery degree enhances by 19.4％.The tested results of the experiment verify that increasing water injection rate can enhance the recovery factor of the remained oil,so it can be one of the effective approaches to enhance the oil recovery for the oilfield at extra-high watercut stage.关键词
