The existing ground emergency rescue truck-mounted drilling rig integral wellhead platform has the following disadvantages: inflexible structure form, small opening aperture, difficult assembly and disassembly, and cannot meet the lowering of large diameter drill bits and casing. In response to the above-mentioned shortcomings, it is proposed that a general scheme of modular large-opening intelligent wellhead platform for vehicle-mounted drilling rigs which combines the requirements of the rescue construction. The modular wellhead platform has the characteristics of fast centering, clamping, automatic leveling and meeting the requirements of multi-series large diameter drilling tools. The numerical simulation method is used to analyze the U-shaped wellhead platform, and an optimized structure is proposed based on the analysis results of the original structure. The results show that the stress of optimized structure is better than that of original structure, which provides important support for product design.
