In the Bohai Sea area,the offshore pile foundation jacket platform is one of the most wide-ly used platform types for oil and gas resources development and application, and its investment has a great effect on the comparison and choice result of preliminary research fast program.Aiming at limited design data about fast comparison and choice stage of the program, and according to building blocks and construction process of the pile jacket platform, main influence factors of pile jacket platform in-vestment are analyzed item by item, and the pile jacket platform investment calculate model is estab-lished.Setting a new platform in Bohai Oilfield as an example,the calculations model is verified through instances.The difference between calculated results and estimated results come from detailed technical data is 7.3%,which meets the requirements of the accuracy in the fast comparison and choice stage.%桩基导管架平台是目前渤海海域油气资源开发应用最广泛的平台型式之一,其投资对前期研究快速方案比选结果具有较大决定作用.针对方案快速比选阶段设计数据有限的情况,根据桩基导管架平台组成模块、施工流程,逐项分析桩基导管架平台投资主要影响因素,建立了桩基导管架平台投资匡算模型.以渤海油田某新建平台为例,对匡算模型进行了实例验证,测算结果与后期按照详细技术资料估算结果差异率为7.3%,满足方案快速比选阶段的准确性要求.
