THE FIRST TEST OF THE DIAMOND BI-CENTER CORING BIT SUCCESSFUL |
| |
| Abstract: | According to the requirement of Chuan Zhong Oilfield,Chuan Shi-Christensen Co.Ltd has designed and manufactured the C201B bi-center coring bit and its diameter is 153 mm(6").Through three continuously coring tests between 3025 meters to 3066.48 meters in Jiao 57 well,the core recovery is 98.48% and the enlargement is 7.5%.Compared to the conventional coring bits and roller bits,the hole enlargement increased by 6.47 percent.This coincides with the design requirements. |
