【摘要】：水平井筛管完井作为目前国内外一种重要完井方式,主要用于油气层比较薄的储层,通过增大油气层的裸露面积来获取较高的产量。本文简要介绍了水平井完井方式的分类及特点,阐述了各种方法的适用范围和优缺点。分析了不同油藏地质条件下的完井方式优选的方法及相关因素。重点介绍了目前常用的三种水平井筛管完井工艺管柱的特点、管柱组成、工艺过程等内容。本文分析和研究了国内筛管完井工具常用的工具:筛管悬挂器、洗井阀、插管、分级箍、管外封隔器等,重点对筛管悬挂器进行了专项分析和研究。本文在对水平井筛管完井工艺管柱的优化设计基础上,进行了完成相关配套工具的优选和改进设计,可为水平井筛管完井工艺管柱设计提供理论依据,确保现场应用的高效、可靠性,这对油田实现稳产和高效益发展意义重大。
[Abstract]:Horizontal screen completion at home and abroad as an important completion method is mainly used for oil and gas reservoir is relatively thin, to obtain a higher yield by increasing the exposed area of oil and gas. This paper briefly introduces the classification and characteristics of horizontal well completion methods, expounds the applicability of various methods and the advantages and disadvantages are analyzed. The preferred method of different reservoir geological conditions of well completion and related factors. This paper introduces three kinds of horizontal screen pipe completion pipe string features commonly used at present, pipe, process and so on. This paper analyzes and studies the domestic screen completion tools commonly used: liner hanger, flushing valve, intubation grading, hoop, packer, focusing on the analysis and research of special liner hanger. Based on the optimization design based on horizontal screen pipe completion pipe string on the finish related with The optimization and improvement design of the set tools can provide theoretical basis for the design of the horizontal well screen pipe completion technology string, and ensure the high efficiency and reliability of the field application, which is significant for the oilfield to achieve stable production and high efficiency development.
