oil recovery efficiency can be raised by injecting a lignosulfonate solution into the oil-bearing reservoir, for lignosulfonate is a kind of anionic surfactant.
同时,亦可利用木质素磺酸盐的表面活性剂性质,将其注入地层,可提高原油采收率。
factors influencing oil recovery efficiency can generally be classified into two large categories: geological features of reservoirs and development and production technologies.
影响采收率的因素大体上可以分为油藏地质特征与开发、采油技术两大类。
the effect of profile control time on oil recovery efficiency is studied by tubular and planar models.
采用长管模型驱油试验和平板模型驱油试验研究了调剖时机对原油采收率的影响。
