ABSTRACT
Conventional high steel drill pipes have been used extensively in oil and gas industries. Due to the higher demands and advancement in drilling up to extended reach well drilling and deeper waters drilling, the demand of pipes with higher susceptible materials to different loadings, installments and corrosion issues are still in developing stage. Therefore, the proposed of composite materials used in drill pipes would be deployed in this project. Firstly, metallic drill pipe data and dimensions were obtained from industrial specifications to construct the drill pipe. The design of the FEA model will be based on a specific grade S- 135 VAM® drill pipe used in industry subject to specific torsional and tensile loadings to verify the safety factor. Furthermore, validation of carbon epoxy fiber properties material was carried out based on the torsion loading on composite shaft from literature. The validation for the torque values obtained from the carbon epoxy fiber were within percentage difference of 0.1% to 2.3% in comparison to the experimental results. The slope differences of the curves within range 36% for carbon epoxy fiber and 30.8% for glass epoxy fiber, between FEA and experimental results. After validation of material properties, both of the slope of the curves improved to 2.4% and 3.8% respectively. The material properties of the carbon epoxy fiber would be applied to design a composite laminate drill pipe to meet the industry loading specifications by using ANSYS ACP. Parameter studies are carried out to study the effect of number of layers, fiber orientation angle and combination of stacking sequence to come up with an optimum design of the composite laminate pipe. Lastly, a design chart based on optimum stacking sequence was produced with respect to the percentage proportion of fiber orientation [+30°/-30°] and [+45°/-45°].
