在石油的勘探开发过程中,油层保护工作直接关系到斟探和开发的效果。在试油施工过程中,固相和滤液会对储层产生一定的影响,如果采用的工艺不适当,就可能会引起渗透率降低,对造成层造成损害,直接影响到油田的采出或注入能力。本文简要介绍了在试油施工中主要存在伤害因素,并提出了几点预防性建议。 In the process of oil exploration and development, reservoir protection is directly related to the effect of exploration and development. In the process of oil testing, the solid phase and the filtrate will have a certain impact on the reservoir, if the process is not properly used, it may lead to lower permeability, causing damage to the formation of a direct impact on the oil field mining or injection ability. This article briefly introduces the main injury factors in oil test construction and puts forward some preventive suggestions.
