在萨哈林亚极地海域,海上钻井面临着气温、海况、环保、运输等诸多问题,在自升式钻井平台市场上并非每一条平台都具备在该海域钻井作业的能力。选择一条适合区域特点的平台是钻井作业成功的关键。通过对区域内自然条件、工程条件、环保要求和运输方式等的研究分析,得出了萨哈林亚极地海域自升式钻井平台优选的关键性指导参数与流程并在平台优选实际过程中进行了应用。结果表明该优选方法符合区域条件特点,能有效保证所选平台的工作质量。

On the shelf of Russian Sakhalin island, there are many challenges in offshore drilling, such as low temperature, harsh sea condition, strict environmental protection policy and transportation problems. In the jack-up rig market, not all jack-up rigs has the capability to drill successfully in this area. The key to the success of drilling operation is to select a proper rig suitable for drilling operation in this area. Through analysis about local environments, engineering conditions, environment protection requirements and transportation problems, the key parameters and process of the optimization jack-up rigs have been obtained. In practice, this selection method had helped successfully the company to choose several high qualified rigs and drill many wells. The result shows that this selection method is suitable to Sakhalin subarctic offshore area condition and can guarantee effectively the quality of the selected platform to complete the drilling operation.
