Analysis on Drilling Fluid Modified by Calcium of Cement and Study on the Treatment

Abstract:

In the operation of casing cementing and hole cement sealing of drilling construction, the cement pollution to drilling fluid is inevitable, which will change the property of the drilling fluid to affect the drilling requirement. According to this problem, by the hydration mechanism of cement and based on the theory of electric double layer produced by clay particle dispersion, the paper analyzed the causes of cement pollution to drilling fluid and put forward a set of effective solution.
