- Separate layer water injection technic is one of the efficient measures for keeping petroleum output steady and improving oil recovery rate. In the actual operating mode, injection string which be placed in the three-dimensional wellbore may produce complicated stress and strain. Analyzing mechanical property in different conditions accurately is very important for improving design level of string and success rate of separate layer injection. Considered wellbore curvature and spatial stress status, a three-dimension mechanical analysis model of layer water injection string was established which analyzed the comprehensive influence of injection tools such as packer, water distributor, centering guide, and the mechanical continuity conditions of injection tools were established. Based on the mechanical model, considering the influence of working parameter, a mechanics behavior analysis method and procedure were proposed in the whole process of the separate injection pipe strings. In addition, the mechanical analysis software was developed using C#, which the research production had been successfully used in Huabei Oilfield.
