主电站设计及原动机选型探讨

Discussion on the Design and Selection of Main Power Plants During Pre-Study Stage

总结歧口17-2、秦皇岛32-6海上油田概念设计阶段主电站设计及原动机选型设计思路,提出了在工程前期研究阶段主电站设计及原动机选型的四大原则和四大设计步骤。重点比较了燃气轮机和柴油/天然气双燃料往复式发动机的优缺点,提出了以主发电机组单机功率大小作为二者选型的衡量标准。

This paper summarizes the new ideas and practices adopted in the design and selection of main power plants in the pre - study stage of offshore oil engineering of Qikou 17-2 oil field, Qinghuang Dao 32 - 6 oil field. Four selection criteria and four steps of design and selection of main power plants in the pre-study for offshore oil engineering are presented in this article. In particular, gas turbines and diesel/gas fueled reciprocating engines are compared. Finally the unit horsepower range as a selecting criterion between gas turbines and dual fuel engines are proposed.
