摘要

塔里木盆地牙哈凝析气田是目前我国已投入开发的最大的整装凝析气田,也是世界上少有的采用循环注气部分保压开采的高压凝析气藏。凝析气藏是一种特殊、复杂的气藏,在开采过程中凝析油气体系在地层及管线中的流动伴随着复杂的相变,在生产上表现为多相流动、相变特征复杂、井流物组分变化大、气油比上升快、井筒积液与层间串流和气串等。因此,与其它类型油气藏相比,凝析气藏的生产动态监测与分析难度大,技术含量高。牙哈凝析气田投产3a来,围绕凝析气井监测中出现的各种特殊现象,以解决实际问题的应用研究为目标,在牙哈凝析气田成功地建立并应用了较为完备的凝析气井监测与分析技术体系,对凝析气藏生产过程中地层物性变化规律、压力变化特征、流体组分及相态特征变化、层间矛盾、注入气对地层析出油的反蒸发效果等都进行了很好的监测和分析,较好地满足了生产动态分析和管理的需要。在总结已有技术成果的同时指出了今后需要重点发展的先进监测与分析技术。

Abstract

Yaha condensate gas reservoir in Tarim basin is the biggest uncompartmentalized condensate gas reservoir under development at present, also is a high pressure one which is developed by the method of partly maintaining the formation pressure by means of gas cycling in world. Condensate gas reservoir is a kind of special, complicate gas reservoir, during the period of the development, the system of the condensate gas flow in formation and pipe with complicate phase change, it appears multiple-phase flow, complicate specificity of phase change, the great change of well fluid composition, rapidly rising of the gas-oil ration, wellbore liquid loading and cross-hole cross flowing, gas channeling and so on. So compared with other kind of oil and gas reservoir, it is more difficult to monitor and analyse the performance, and the requirement for  the technique is higher. The Yaha condensate gas reservoir has been developed for three years; being aim to the all kinds of special phenomena in the performance  monitoring and to applied research for resolving the practical problem, in Yaha condensate gas reservoir, successfully establish and apply the complete technique  system for monitoring and analyzing the performance of condensate gas wells; and it is better to monitor and analyse the changing law of formation property, the  feature of pressure change, the change of the liquid composition and the feature of phase changing, the contradiction between lays, the injected gas to the  effect of counter evaporation of condensate oil and so on, during the development of the condensate gas reservoir; and it satisfies the requirement of the  performance monitoring and analysing. This paper summarises present  technical outcomes and preview the advanced monitoring and analyzing technique.
