海洋修井机和模块钻机井架应力测试工装设计

Stress Test Tooling Design for Derricks on Offshore Workover Rig and Module Drilling Rig

摘要: 中国海洋石油在役的海洋修井机、模块钻机已过百台，由于其所处的海洋易腐蚀的特殊环境，这些设备的定期检测任务越来越繁重。特别是井架的承载能力检测，在作业期间还可以利用管柱负荷进行应力测试，而大多数井架，需要在非作业期检测。设计几款通用性好、安全可靠、耐用且易于操作的井架应力测试工装就显得尤为必要。在通过调研大多数海洋修井机和模块钻机的基础之上，设计了3款可以涵盖多种规格海洋修井机和模块钻机的通用型井架应力测试工装，有效解决了海洋修井机和模块钻机在定期检测过程中的井架应力测试问题。

Abstract: China National Offshore Oil Corporation owns over a hundred offshore workover rigs and module drilling rigs in service. The routine test of the equipment has become an arduous task due to the corrosive offshore working environment. In particular, the load test for derricks could be difficult to perform since drilling pipes are usually not available for testing during non-operational periods. Therefore, stress test tooling with good universality, safety level, durability and easy operation becomes a necessity for offshore operations. Based on research on offshore workover rigs and module drilling rigs, the author designed three models of tooling for routine derrick stress tests.
