中国近海自升式钻井平台选型影响因素分析

中国近海油气产量高速增长,带来了钻完井工作量的剧增,致使自升式钻井平台数量不足的矛盾突显。本文从自升式钻井平台类型和特点入手,揭示了自升式钻井平台选型所考虑的水深条件、海底地质条件、钻井能力以及海况条件等因素之间的相互关系,提出了通过自升式钻井平台选型能够避免钻井平台作业风险和提高自升式钻井平台利用率的研究思路。

Affecting factor analysis on type selection of jackup rig for offshore China

The contradiction of scarce of jackup rig with the increasing of drilling and completion work load is obviously for accelerating the oil and gas production offshore China.The correlations among water depth,sea bottom geology,drilling capacity and sea conditions considered in type selection of jackup rig is revealed for its type and feature.The research way is proposed to avoid operation risk and raise platform utilization ratio by type selection of jackup rig.
