| Abstract: | The composite fracturing string has the problems of unreasonable tubing length configuration and excessive axial tensile safety factor. Taking the axial tensile safety factor as the design goal, the force analysis of each section of the composite string was carried out, the calculation formula of each section of the tubing length was deduced, and the factors affecting the length of each section of the tubing were revealed. Taking the 3 700 m long composite pipe string as an example, the safety factors of the optimized composite fracturing string meet the requirements and can reduce the amount of pipe used by 15%. |
