中东M油田两种沥青成因、分布及治理措施研究

Study on Origin, Distribution and Treatment Measures of Two Kinds of Bitumen in M Oilfield in Middle East

摘要: 为了评价中东M油田储层沥青和生产析出沥青对开发生产的影响，减少储层沥青对钻井的危害，提出析出沥青生产井的增产措施和预防措施，做好油田管理，本文分析了中东M油田钻遇沥青井的地质油藏情况，研究了不同层位沥青的物理、化学性质，分析了M油田储层沥青的形成机理，沥青对开发的危害，并对储层沥青分布进行了预测。本文同时分析了生产井出现沥青堵塞的状况、析出沥青机理和分布规律，研究了解堵措施，以及已实施井的成功经验启示，为类似油田出现的沥青问题，提供了研究和解决措施。

Abstract: In order to evaluate the impact of reservoir bitumen and producing precipitated asphalt on development and production in M oil field in the Middle East, reduce the harm of reservoir bitumen to drilling, propose stimulation and prevention measures for precipitated asphalt production wells, and do a good job in oilfield management, this paper analyzes the geological reservoir conditions of drilling into bitumen wells in M oil field in the Middle East, and studies the physical and chemical properties of bitumen in different layers. This paper analyzes the formation mechanism of reservoir bitumen in M oilfield, the harm to development of oil field, and predicts the distribution of reservoir bitumen. At the same time, this paper analyzes the situation of asphalt plugging in production wells, the mechanism and distribution of asphalt precipitation, studies and understands the plugging measures, and the successful experience of the implemented wells. The research and solution measures are provided for the bitumen/asphalt problems in similar oil fields.
