采用注水开发的油田，注入水水质的质量，是直接影响油田开发的关键。而注入水中悬浮固体颗粒的含量及大小又是影响注水水质的重要指标。造成伤害地层的重要因素。在油田开发过程中．根据油田情况、油藏物性，采用岩芯注水试验法研究注入水中悬浮固体颗粒的含量及大小对地层伤害机理，确定注入水水质控制指标，对选择技术上可行，经济上合理的注入水水质处理工艺有着重大的指导意义。在研究过程中，对试验用含悬浮固体颗粒的注入水应有统一的要求，以保证试验终论断科学性。准确性、通用性，本交通过对国内外应用岩芯注水试验开展注入水中悬泽固体颗粒对地层伤害机理研究的探讨，提出开展若芯注水试验对含悬浮固体颗粒注入水的几点要求。
The use of water injection development of oil fields, injection quality of water quality is the key to the direct impact on the development of the oil field. However, the content and size of the suspended solid particles injected into the water are also important indexes that affect the water quality of the injected water. An important factor that hurts the formation. In the oilfield development process. According to the condition of the oil field and reservoir properties, the core injection test method was used to study the content and size of the suspended solid particles in the injected water and to determine the mechanism of damage to the formation. The index of water quality control was determined, and the choice of technically feasible and economically reasonable injection water quality treatment Technology has great guiding significance. In the course of the study, there should be a uniform requirement for the test injection of water with suspended solids to ensure that the test is final and scientific. Accuracy and universality of this paper, we discuss the mechanism of strata damage caused by solid particles injected into the water by using core injection test both at home and abroad, and put forward several requirements for injecting water into solid particles with core flooding test.
