油藏一经投入开发,影响剩余油产生的因素便应运而生。目前世界石油采收率平均为33%左右,67%的石油储量仍然剩余在地下油藏中,也就是说,能够采出的石油只占总储量的极小部分这种现状,客观上是由油藏本身的地质条件决定的,它是影响剩余油形成的最主要因素;而影响剩余油产生的另外一个重要因素-开发条件,除受当时的技术、经济条件等客观因素制约外,带有较强的主观性质。
Once the reservoir is put into development, the factors that affect the remaining oil come into being. At present, the average oil recovery rate in the world is about 33%, and 67% of the oil reserves remain in the underground reservoirs. That is, the current situation in which oil can be extracted only accounts for a very small part of the total reserves is objectively caused by The geological condition of the reservoir itself determines the most important factor that affects the formation of remaining oil. Another important factor affecting the generation of remaining oil, that is, the development conditions, is subject to objective factors such as the technical and economic conditions of the time. Strong subjective nature.
