Abstract: Integrated drilling engineering design system is a set of drilling system software for engineering design of various well types, such as straight wells, directional wells and horizontal wells. This system is based on the drilling engineering software platform and unified database. It also adopts the drilling design format of PetroChina Exploration and Production Company, meets the latest requirements on drilling design format stipulated by CNPC’s various oilfields, optimizes drilling design process and software design interface, and improves application efficiency of drilling design data. It has a series of functions, such as well trajectory design and anti-collision scanning, editing and drawing of well structure, casing string design and casing trip-in analysis, design of drilling bits and parameters, drilling string design and drag torque analysis, and design and calculation of drilling fluid and completion fluid. The software can automatically provide the drilling engineering report according to the customized format. Field application indicates that the software is at the same level with its foreign counterparts in terms of functional module and calculation accuracy of software, able to meet the demand for drilling engineering design and analysis. Integrated drilling engineering design system improves China’s independent creativeness and original technological development capacity of drilling engineering design and process software, enhances CNPC’s drilling engineering competitiveness and contributes to the country’s development of drilling technological informatization, automation and intelligence.
