Introduction

 Coiled tubing (CT) has many programs within the petroleum industry, which encompass drilling (CT drilling), cementing, wellbore cleanup, oxidizing, and hydraulic fracturing. In contrast, the immoderate friction stress loss, because of the noticeably small tubing diameter and tubing curvature (which is assumed to be secondary to the drift) of CT, regularly limits the most available fluid injection rates. Therefore, it's of realistic significance to research the drift regularity and friction homes in CT
