摘要

本文成功地将地球工程工作流程应用于综合试井分析,对巴伦支海新发现的裂缝性储层进行了流体流动特征描述。利用该工作流程建立并校准了包含裂缝和基质的储层模型,以匹配现场测量的复杂压力瞬变。我们概述了可能重现现场观察到的压力响应的不同地质情景,强调了在分析试井数据时非唯一性的挑战。然而,将其他现场数据整合到分析中,使我们能够缩小不确定性的范围,从而能够采用最合理的地质情景,进行更详细的储层表征和历史匹配。研究结果为油藏地质和产生现场观察到的压力响应的关键流动过程提供了新的见解。本文表明,本文采用的地球工程工作流程可以更好地描述天然裂缝性储层。我们还为裂缝性油藏的试井解释提供了参考解决方案,这些油藏的压力导数在数据中可以识别出波谷。

Calibration of naturally fractured reservoir models using integrated well-test analysis – an illustration with field data from the Barents Sea
This paper successfully applied the geoengineering workflow for integrated well-test analysis to characterize fluid flow in a newly discovered fractured reservoir in the Barents Sea. A reservoir model containing fractures and matrix was built and calibrated using this workflow to match complex pressure transients measured in the field. We outline different geological scenarios that could potentially reproduce the pressure response observed in the field, highlighting the challenge of non-uniqueness when analysing well-test data. However, integrating other field data into the analysis allowed us to narrow the range of uncertainty, enabling the most plausible geological scenario to be taken forward for more detailed reservoir characterization and history matching. The results provide new insights into the reservoir geology and the key flow processes that generate the pressure response observed in the field. This paper demonstrates that the geoengineering workflow used here can be applied to better characterize naturally fractured reservoirs. We also provide reference solutions for interpreting well tests in fractured reservoirs where troughs in the pressure derivative are recognizable in the data.

期刊介绍: Petroleum Geoscience is the international journal of geoenergy and applied earth science, and is co-owned by the Geological Society of London and the European Association of Geoscientists and Engineers (EAGE). Petroleum Geoscience transcends disciplinary boundaries and publishes a balanced mix of articles covering exploration, exploitation, appraisal, development and enhancement of sub-surface hydrocarbon resources and carbon repositories. The integration of disciplines in an applied context, whether for fluid production, carbon storage or related geoenergy applications, is a particular strength of the journal. Articles on enhancing exploration efficiency, lowering technological and environmental risk, and improving hydrocarbon recovery communicate the latest developments in sub-surface geoscience to a wide readership. Petroleum Geoscience provides a multidisciplinary forum for those engaged in the science and technology of the rock-related sub-surface disciplines. The journal reaches some 8000 individual subscribers, and a further 1100 institutional subscriptions provide global access to readers including geologists, geophysicists, petroleum and reservoir engineers, petrophysicists and geochemists in both academia and industry. The journal aims to share knowledge of reservoir geoscience and to reflect the international nature of its development.
