Drilling Fluid and Completion Fluid | Year: 2014
Cementing the hole section drilled with high density oil base drilling fluid in the piedmont structure and deeper formations in Tarim Basin is always a challenge. Studies are conducted on the properties of a flushing heavy space and cementing slurries, and the design of casing string and cementing technology. Using a spherical weighting material, MicroMAX and an optimized surfactant, a flushing weighted space was obtained. A cementing slurry with superior overall performsnce was developed through optimization of additives and using ultra-high density additive, GM. Field application on Well KS2-5 showed that this technology can be sued in cementing the wells drilled with oil base drilling fluid in the piedmont structure in Tarim Basin.
