未开采的

The determining methods and its developing methods of the unswept remaining oil are now summarized.

概述了目前确定未波及剩余油的方法及其开采方法，指出这项研究的难度很大，是当前油田开发的核心技术之一，可以称得上是世界级的世纪难题。

This paper compares variability of petroleum biodegradation bacteria in frozen and thawed soil collected from Liaohe Oil Field and their capacities for biodegrading petroleum were also determined. The results show that 14 strains of bacteria and 6 strains of fungi for petroleum biodegradation were screened from thawed soils, while only 5 strains bacteria and 2 strains fungi existed in freeze soils.

以辽河油田不同年代开采油井附近采取的土壤样品为研究对象，通过冻融模拟试验和采用选择性培养基筛选对石油污染土壤具有原位修复作用的优势微生物菌株，并比较油田冻结土壤与未冻结土壤中石油降解细菌与真菌的数量变化特征及其对石油的降解能力。

The split between the two groups can hardly be papered over.
