为了克服海上模块钻机在传统作业模式中建造费用高、周期长、设备及人员需要磨合期和作业管理难度大等诸多难题，需要探索一种新型作业模式。通过合理分配人员和设备资源，模块钻机建造阶段钻完井方提前介入调试，对设备进行最大限度的国产化，充分协调钻完井方、采油方和修井方之间的关系，提出并实践了一种新型作业模式，提高作业效率的同时更好地发挥了现有设备的价值。应用此模式可以在共用钻井支持模块（DSM）的平台实现钻完井和修井同时作业，互不干扰，提高作业效率。经过渤中28油田某平台的现场应用，该模式发挥了目前已有设备价值，使平台整体建造费用大幅降低，现场修理比率控制在较低水平，钻完井和修井作业可同时进行。

In order to overcome the problems of the offshore MDR(module drilling rig) such as high construction cost, long cycle, equipment and personnel to run-in period, and difficult operation management in the traditional mode of operation, it is necessary to explore a new mode. By rationally allocating personnel and equipment resources, construction of MDR drilling early intervention debugging,the maximum of domestic equipment, coordinate the relationship between the drilling and completion, the oil recovery and workover, a new mode of operation has been proposed and practiced to improve work efficiency and play a better role in the value of existing equipment. Using this model, the drilling and workover operations can be done at the same time in the platform sharing drilling support module (DSM), without interfering with each other and improving work efficiency.Through the on-site application of a platform in Bozhong 28 oilfield, the model has exerted the existing value of equipment, which greatly reduced the overall construction cost of the platform, and the on-site repair ratio was controlled at a lower level. The drilling completion and workover operations can be carried out simultaneously.
