摘要/Abstract

摘要： 随着渤海油田开发程度的不断深入,油藏地层压力分布越来越复杂。合理的地层压力是指导油田生产以及调整挖潜的重要条件,及时准确地了解地层压力变化对于后期开发方案的制定和优化具有重要意义。常规电缆测压工具在海上大斜度井中难以完成相关测试工作,采用随钻测压工具在钻井过程中可实时测量记录地层压力,是获取油藏小层压力的重要手段。通过随钻测压工具在渤海油田大斜度调整井中应用,获取地层压力值来精细刻画油藏能量衰竭剖面,并运用所得压力数据实现了快速准确判断主力层位压力变化及井间连通性分析,同时为注采优化提供了可靠依据,为油田后期开发调整提供了有益指导。

Abstract: With the deepening of the development of Bohai Oilfield,the distribution of formation pressure in the reservoir becomes more and more complicated. Appropriate formation pressure is an important condition to guide oilfield production and potential tapping adjustment. A timely and accurate understanding of formation pressure changes is of great significance to the formulation and optimization of later development plans. It is difficult for conventional cable pressure measuring tools to complete relevant testing work in offshore highly deviated wells,while pressure measurement tools while drilling measure and record formation pressure in real time during drilling,which is an important means to obtain the thin layer pressure of the oil reservoir. Through the application of pressure measurement tools while drilling in high angle deviated adjustment wells in Bohai Oilfield,the formation pressure values are obtained to precisely describe the profile of reservoir energy depletion,and data obtained can quickly and accurately determine the pressure changes of the main formation and analyze the connectivity between wells. Meanwhile,it provides a reliable basis for injection-production optimization,and a useful guidance for the later development adjustment of the oilfield.

Key words: pressure measurement while drilling, formation pressure, reservoir connectivity, injection-production optimization, Bohai Oilfield
