摘要:

目前,我国大部分油藏已进入了开发中后期,需通过三次强化采油技术来提高原油的采收率。由于深层超深层油藏普遍存在高温高盐特征,单一驱油体系已难以适应当今油田开采的需要。基于此,本文综述了国内外各类耐温抗盐型驱油体系的研究进展及应用现状,包括表面活性剂驱、聚合物驱、泡沫驱以及纳米流体驱油等。通过阐述这几种驱油体系的结构与性能,剖析其作用机理与驱油效果,并结合矿场实际应用成效,对深层超深层油藏耐温抗盐驱油体系进行了详细总结,为未来的重点研究方向打下基础。结果表明:对于深层超深层油藏而言,开展耐温抗盐驱油体系研究,能够有效提高油藏开发后期采收率,保证剩余油的全面动用。未来对耐温抗盐驱油体系的研究方向应重点放在以下几个方面:一是能够更大程度地降低界面张力;二是降低成本,采用最低的成本最大程度地达到更好的生产效益;三是研究不同类型驱油剂之间的协同性能。

Abstract:

At present, most of the oilfields in China are in middle and late stages of development and it is necessary to improve the oil recovery by tertiary enhanced oil recovery technology. Deep and ultra-deep reservoirs, due to the high temperature and high salt characteristics, make it difficult for a single oil displacement system to meet the needs of current oilfield exploitation. Based on this phenomenon, the research progress and application status of various types of temperature and salt resistant oil displacement systems at home and abroad were reviewed in this paper, including surfactant flooding, polymer flooding, foam flooding and nanofluid flooding. By expounding the structure and performance of these oil displacement systems, analyzing the action mechanism and oil displacement effect, and combining with the actual application effect in the field, the temperature and salt resistant oil displacement systems in deep and ultra-deep reservoirs were summarized in detail, which laid the foundation for the key research direction in the future. The results showed that for deep and ultra-deep reservoirs, the research on temperature and salt-resistant oil displacement systems can effectively improve the oil recovery in the later stage of reservoir development and ensure the comprehensive production of residual oil. The future research directions for temperature and salt resistant oil displacement systems should focus on the following aspects. Firstly, it can reduce the interfacial tension to a greater extent. Secondly, it was to reduce the cost and use the lowest cost to achieve better production efficiency to the greatest extent. Thirdly, it was to study the synergistic performance between different types of oil displacement agents.

Key words: deep and ultra-deep reservoirs, temperature and salt resistant, oil displacement system, tertiary recovery, enhanced oil recovery
