磁降凝、降粘技术配合热水循环工艺使一些难以开采的油井正常生产,从而提高油井的产量和采收率

Hydrolyzed polyarylamide and Xanthan have been extensively used in enhanced oil recovery .

使用聚合物提高石油采收率是三次采油化学驱中最具有经济价值的一种方法。

Depending on the geometry of gas-cap and oil column, the physical property and geometric shape of reservoir, and the mobility of edge and bottom water, the multiple oil-driving mechanisms exist in gas-cap reservoirs where there are gas-cap and oil/gas interface, and the recovery factor changes a lot because the oil/gas interface moves during exploitation of gas-cap reservoirs and it is very difficult to adjust and control the oil/gas interface.

气顶油气田因气顶及油气界面的存在,同时因气顶和油环的大小、储层物性、几何形态不同和边底水活跃程度不同,致使气顶油气藏在开采过程中具有多种驱油机理,采收率变化较大,这关键是气顶油气藏在开发过程中存在油气界面的移动问题,而调整和控制油气界面是相当困难。

The results showed that,by using G-ECBM technology,coalbed methane recovery ratio can be enhanced substantially,and the time for coalbed methane pre-extraction can be shortened thus improving the efficiency of coal mining.

研究结果表明采用地面混合气体驱替煤层气技术可以大幅提高煤层气采收率、缩短煤层瓦斯预抽时间、提高采煤效率

High-precision and wide-range saturated vapor density compensator is put forward to solve this problem.

在石油开采特别是在稠油热采工艺中,需要注人高温、高压、高干度饱和水蒸汽以提高油汽比和原油采收率

The author suggests that people should only use the rigorus definition of miscibility in phisical chemistry and give up the miscibility decision methods using the turning point or the value of recovery in slimtube test, in order to clean up the confusion of miscibility conception.

本文作者建议,采用物理化学意义上严格的混相定义,放弃细管实验中用采收率拐点或数值判定混相的方法,以便澄清混相概念上的混乱。

Nitrogen injection being used to enhance oil recovery in many oilfields, particularly in over thrust fault .

许多油田,特别是在逆掩断层油藏中,正在大量注氮提高原油采收率

The functions and diversities of the bacteria need to be studied further for the application of improving oil recovery fac...

它们的功能和多样性有待于深入研究,以便进一步筛选用于提高该油田原油采收率的采油功能菌群。

The application results of the N2 injection technology in Guantao reservoir of Du 84 block showed that the N2 injection technology during SAGD process was feasible and beneficial for expansion of steam chamber in sideways and increase of the horizontal sweep volume. N2 injection during SAGD process could effectively control the down flow of top water and lengthen SAGD production time by 3-4 years. Both the reservoir recovery factor and oil steam ratio could be improved.

研究结果表明,氮气辅助SAGD开采技术在杜84块馆陶油层开采中是可行的,有利于蒸汽腔的侧向扩展,增加蒸汽的横向波及体积;在SAGD过程中添加氮气能够有效控制顶水下泄,延长SAGD生产时间3~4年,提高了油藏采收率和油汽比。
