Sažetak
According to recent investigations fatigue is the major factor controlling the service life of coiled tubing. the rate of fatigue damage accumulation is affected by a number of operating factors: mechanical damage, corrosion damage, damage incurred by exceeding the ultimate capacity of the string, and damage due to cycling plastic strain or fatigue. While drilling there is an additional load on the coiled tubing due to friction with the well wall/rocks regardless the drilling mode ; rotating or sliding. Determination of the actual friction coefficient is essential in defining the project technical feasibility. As a part of drilling system drilling fluid can impact on the reduction of friction coefficient by implementation of lubricants. Selection of lubricants, their compatibility with drilling fluid and formation fluids and rocks was determined through laboratory testing. The results are shown and elaborated in the paper.
