由于现有开采技术的限制,对于投资回报率未能达到油公司内部收益率的油田统称边际油田。本文总结了现有边际油田开发模式的优缺点,提出一种新型无依托油田的开采模式,此种形式对于分布分散,可供依托平台较远的油田优势显著。解决运输油轮和平台之间的连接方式是本方案的核心技术之一,作者通过对假定的连接形式进行数值模拟,计算出船体对导管架的撞击荷载,同时结合经济效益和可操作性,指出这种连接形式的可行性,供此类边际油田的开发研究参考。
Due to the limitations of existing mining technologies, the fields with marginal returns on investment that do not meet the internal rate of return of oil companies are collectively referred to as marginal oil fields. This paper summarizes the advantages and disadvantages of the existing marginal oilfield development model and puts forward a new exploitation mode of the non-relying oilfield. This kind of mode has significant advantages for oilfields with dispersed distribution and available platform. It is one of the core technologies to solve the problem of the connection between the transportation tanker and the platform. The author calculates the impact load of the hull on the jacket through the numerical simulation of the assumed connection form, and at the same time points out the economic benefits and maneuverability The feasibility of this form of connection for the development of such marginal oil fields for reference.
