    A polymer sulfonate inhibitive drilling fluid was successfully used in Block Xiepoxiliu in County LI (of Hebei Province). This fluid has good lubricity and inhibitive capacity, and easy-controllable rheology. Twenty three wells have been completed using this fluid, and no downhole troubles were encountered. Av-erage percent borehole overcut was only 8.51%.
