Research Progresses of Hydraulics for Extended Reach Drilling in China, Part III: Hydraulics Design Method and Risk Analysis System

Abstract:

The extended reach drilling (ERD) is being adopted widely in China. But it also brought a series of technical difficulties because of its own characteristics. Some progresses were made after several years of hard work in China about Hydraulics for ERD. In the paper of “Research Progresses and Perspectives of Hydraulics for Extended Reach Drilling in China, Part I” and “ Part II”, the author demenstrated part of these progresses including cuttings transport model, precise model of pressure loss calculation, hole cleaning monitoring method and hydraulic extended limit calculation model and analysis. In this paper, the rest were presented which inlcuding hydraulics design method and risk analysis system for ERD. Based on the above studies, the author finally developed a system of hole cleaning monitoring and hydraulics design and its risk analysis which could provide theoretical support and useful tool for engineering design and risk analysis before drilling. These researches are helpful to ERD and have enriched the hydraulic theory of ERD.
