乌干达N油田流体界面探讨

Study on the Fluid Contact of N Oilfield,Uganda

近年来,海外并购成为中国石油公司对外投资的主要形式,而合理准确评估油田储量是海外并购成功的前提。本文以乌干达N油田为例,分析认为流体界面是影响油田储量评价的关键参数,并充分利用地震、测井、测压资料,确定油田流体界面,结合断层封堵性分析探讨控制流体界面的主要因素。力求最大程度降低储量评价中流体界面不确定性,为后续油田开发打下坚实基础。

In recent years,overseas acquisitions as the main form of Chinese oil companies＇ investment,its success is on the basis of reasonable and accurate reserve estimate.In Ugandan N oilfield,fluid contact is the key parameter of reserve estimate,this paper determine the oilfield fluid contact,based on seismic,logging,pressure data,and discusses the main control factors of fluid contacts by combining with fault sealing analysis.It reduces uncertainty of fluid contact in the reserve estimate and provides a solid foundation for subsequent oilfield development.
