Design For Extraction And Repair Of Wells Integration Platform Mobile Workover Module And Process

The traditional offshore operation equipment is unable to satisfy present Marine Cong Shijing Well head rework operation demand. Many oil wells cannot carry on the rework operation promptly. That serious influences the oil field marine crude oil produces. In order to resolve the marine oil gas development contradiction which this restriction equipment creates. Proposed marine picks repairs the integrated platform mobile repair of wells module the new mentality.Picks repairs the integrated platform mobile repair of wells module is a set which has 3500 rice oil gas well repair of wells function new work equipment, mainly by the service machine main body module, repairs constitutions and so on well pump module, purification module, electrically controlled module, may about the long distance migration complete several dozens oil wells in a platform the job tasks, can realize in many platform well group the hoisting use. Reduced the marine oil gas development cost of investment, raises the equipment utilization rate.This article first introduced picks repairs the integrated platform the structure composition and the principle of work, the platform gross structure design, the repair of wells module design.Next, introduced the repair of wells craft system's composition and the design reference standard, has carried on the reasonable disposition to the repair of wells craft system, including the sea service machine, repairs the well pump, the throttle to kill the well the valve group, the pressure manifold, the purification system and the well controls the equipment and so on, has carried on the detailed design calculation to repair of wells craft various departments.Once more, picks take CB11N repairs the integrated platform repair of wells module as the object, introduced the overall construction composition, the arrangement and rework operation ability.Finally, picks to CB11N repairs the integrated platform repair of wells module the primary structure to carry on the structural design and the finite element strength calculation analysis. According to design loadings in API Spec 4F, the static characteristics of offshore derrick is completed.
