The truck can complete the well site flushing operation itself, and has the advantages of big flushing fluid capacity, good water treatment, and high efficiency, handiness and good acclimation. 该洗井车具有能单独完成井场洗井作业的功效,同时还具有洗井强度大、水处理效果好、高效、轻便、适应环境强等特点。
In order to better recover the by-passed oil in reservoirs, EOR technologies that can improve both sweep efficiency and flushing efficiency are needed. 要想较好地挖掘层内剩余油,就必须有既提高波及系数,也有提高洗油效率的提高原油采收率的技术。
Flushing efficiency of displacing fluid can be increased by eliminating or decreased surface tense between displacing fluid and oil, and then residual oil can be decreased dramatically, some recovery means like miscible flooding and surfactant flooding can be used. 驱替流体的冲刷效率是靠消除或降低驱替液与原油之间的界面张力而增加的,随着剩余油的减少,人们可以使用一些其它开发方法如混相驱和表面活性剂驱油技术。
They focus on formation conformance efficiency and flushing efficiency, and all the recovery techniques are based on these two respects, and the corresponding techniques are called tertiary recovery or Enhanced Oil Recovery ( EOR). 他们关心地层的波及效率和冲刷效率,所有的驱替开采技术都基于这两个方面,按照技术的分类把它称为三次采油或称为提高采收率法采油。
The impeller flushing system is used for the air compressor associated with 730t/ d air separation plant in Taiyuan Steel in order to improve the efficiency of the air compressor and to reduce the shaft vibration. 为了提高空压机的效率、降低轴振动,太钢730t/d空分设备配套的空压机采用了叶轮冲洗系统。
Effects of thin meander dot dam interbeds on flushing efficiency and on formation and distribution of residual oil 曲流点坝薄夹层构形对驱油效率及剩余油形成与分布的影响
