注入水中所含机械杂质的浓度、颗粒大小不同对地层裂缝、孔隙所产生的阻塞作用和对油井产量的影响就不同。在实验室研究这一问题时 ,遇到的一大难题就是如何使注入水中机械杂质在长时间的实验过程中保持均匀分布。注入水机械杂质悬浮装置就是为此而研制的。简要介绍了注入水中不同机械杂质堵塞岩心程度和规律的实验流程图 ,重点阐述了其中带搅拌器的高压中间容器的结构组成 ,悬浮机械杂质的工作原理 ,以及主要零部件的设计计算。通过对试制样机的试验运行 ,其结果表明该装置工作可靠 ,能使注水中的机械杂质均匀悬浮 ,且不改变注入水的压力及特性 ,提高了注入水的渗透率 ,保证了注入水含不同机械杂质对油井生产影响的实验研究。
The concentration and particle size of the mechanical impurities contained in the injected water have different effects on the formation cracks and pores, and on the oil well production. One of the major challenges encountered when investigating this problem in the laboratory is how to keep the mechanical impurities injected into the water evenly distributed over a long period of experimentation. Infusion of mechanical impurities suspended device is developed for this purpose. The experimental flow chart of the degree and regularity of plugged cores with different mechanical impurities injected into water is briefly introduced. The structure of the high pressure intermediate container with stirrer, the working principle of suspended mechanical impurities and the design and calculation of main components are mainly discussed. Through the trial operation of the trial prototype, the results show that the device is reliable, can make the mechanical impurities in water floated evenly, and does not change the pressure and characteristics of the injected water to improve the permeability of the injected water to ensure that the injected water contains different Experimental Study on the Effect of Mechanical Impurities on Oil Production.
