近五年多来,交流可控硅电驱动钻机的建造及其应用已大大增加,从而代替了机械驱动钻机和直流—直流电驱动钻机。虽然大家公认交流可控硅电驱动钻机的操作较为经济,但在这方面却几乎没有提出具体数据,所做的分析也较少。本文对交流可控硅电驱动钻机的成本作出评价,并与机械驱动钻机,直流电驱动钻机作一比较,包括一次投资、操作成本、维护保养成本、修理成本以及由于停机时间所造成的经济损失。同时,还提出一些用于降低成本的操作程序方面的建议。了解交流可控硅电驱动钻机的优点以及正确地培训井队人员可以减少成本。为获得交流可控硅电驱动钻机所能节约的成本,下面介绍钻机进行成本比较的一个
In the past five years, the construction and application of AC SCR drive rigs have greatly increased, replacing mechanical drive rigs and DC-DC driven rigs. Although it is generally acknowledged that the operation of the AC thyristor-driven drilling rigs is more economical, there is almost no concrete data presented in this respect and less analysis done. This article assesses the costs of AC-controlled electric drive rigs and compares them to mechanically-driven rigs and DC-driven rigs, including an investment, operating costs, maintenance costs, repair costs, and economic losses due to downtime. At the same time, some suggestions on operating procedures to reduce costs were also made. Understanding the benefits of communicating with a silicon controlled electric drive rig and the proper training of the crew can reduce costs. In order to obtain the exchange SCR electric drive drilling rig can save the cost, the following describes the cost of drilling rig comparison
