数值试井在上古砂岩气藏中的应用研究

常规试井技术在均质性油气藏、单相渗流范畴内已较为成熟,但对于井间干扰、储层非均质性强、外边界形状不规则及多相流等问题无法解决,本文针对榆林气田上古砂岩气藏的特征,分析了解析试井的局限以及数值试井解释方法的优势,总结了在上古砂岩储层复杂气井的数值试井应用情况,详细描述了采用常规解析试井分析方法和数值试井分析方法的过程,对比分析两种方法的解释结果,讨论不同解释方法的特点、效果和使用条件。进一步完善了试井解释技术、提高试井技术的应用水平和效果。数值试井方法在上古砂岩气藏的实际应用表明了该方法具有良好的使用效果。

Valuewell test in antiquity sandstone gas pool's applied research

The conventional well test technology in homogeneity oil gas pool,in the single-phase transfusion category has been maturer,but disturbs,the reservoir anisotropism regarding the well between strong,outside the boundary shape to be anomalous and question inextricabilities and so on polyphase flow,this article in view of the Yulin natural gas field antiquity sandstone gas pool's characteristic,has analyzed the analysis well test limitation as well as the value well test explanation method superiority,summarized in the antiquity sandstone reservoir complex gas well's value well test application situation,described in detail has used the conventional analysis well test analysis method and the value well test analysis method process,the contrastive analysis two method explanation results,the discussion different explanation method characteristic,the effect and the exploitation conditions.Further consummated the well test to explain that the technology,enhanced the well test technology the application level and the effect.The value well test method had indicated in the antiquity sandstone gas pool's practical application this method has the good use effect.
