长庆油田伴生气生产特征分析

摘要

A field test and sampling data of associated gas of Changqing Oilfield were analyzed, starting from two aspects: variation of petroleum characteristics and recovery feature(characteristics), and by classifying different water content levels and application of the mathematical statistical method, features of production performance of associated gas were investigated and discussed . The changes of factors of formation pressure , production gas- oil ratio, bottomhole flowing pressure, and water content etc are discussed, and the basic features of production performance of associated gas are summarized, it provides a reliable basis for an integral application of associated gas in oilfields.%通过对长庆油田伴生气现场测试和取样数据调查分析,从油气性质变化特征和开采特征两方面入手,按不同含水级别进行划分,应用数理统计的方法研究了伴生气的生产变化特征,讨论了生产气油比与地层压力、井底流压、含水等因素的变化关系,总结了伴生气基本生产动态特征,为油区伴生气的综合利用提供了可靠的参考依据.
