Laboratory Study on Effect of Formation Fluid on Performance of Coated Ceramsite Artificial Core
In order to investigate the influence of formation fluid on the consolidation strength of coated ceramsite after entering the formation,different fluid tolerance evaluations were carried out in the laboratory.The results showed that the compressive strength of artificial core formed by coated ceramsite changed little after they were soaked in the fracturing fluid gel breaker and formation oil and water at 60℃ for a certain time,and the maximum reduction rate of compressive strength was not more than 1.5%.
