摘要
针对松南火山岩气藏储层岩性岩相变化快、非均质性强,数据测试不规范,前期地质认识与动态跟踪存在出入等问题,分析了压力卡片原始数据,剖出杂点及干扰点,寻找真实反映火山岩储层的压力响应;多种方法结合,确定了合理的储层解释;测试与地质、动态相结合,从多角度验证试井模型的可靠性,为火山岩气层识别提供评价依据。
Songnan volcanic gas reservoir is characterized by quick change lithology and lithofacies,and strong heterogeneity;the pressure transient data were not tested with standard;reasonable explanations were hard drawn because of differences between geological understanding and dynamic analysis.The original test data were analyzed and noise points were moved in order to find the true pressure response of volcanic reservoir.Then,the reasonable reservoir interpretations were determined from the principle and the combination of various methods.Finally,the correctness of well test models was verified from analyzing the relationships among tests,geology and dynamics systematically,which laid the foundation for the identification of volcanic gas reservoir.
