摘要:

近年来,沁水盆地煤层气勘探开发不断深入,煤层气富集规律是制约其勘探开发成效的关键因素之一,而 AVO 技术对煤层气富集规律的预测至关重要。 煤层的 AVO 响应特征是什么样的? 煤层含气后的 AVO 响应特征又是什么样的?其与常规砂岩含气后的 AVO 响应特征是否一致?对此,在沁水盆地开展了不同岩性流体替换及其在不同含气饱和度下的 AVO 响应特征研究。 结果表明,煤层的 AVO 响应特征与煤层含气后的 AVO 响应特征不同,煤层为“暗点”反射特征,而煤层含气后为“相对亮点”反射特征。 该研究成果可为煤层气勘探开发提供技术支撑与服务。

Abstract:

With the deepening of exploration and development of coalbed methane in Qinshui Basin, It was found that the enrichment rule of coalbed methane is one of the key factors influencing the development efficiency, and AVO technique is important to predict the enrichment rule of coalbed methane. What are the AVO response characteristics of coalbed and coalbed methane? Are they as the same as sand bed gas? For these questions, this paper studied the fluid substitution of different lithologies and its AVO response characteristics under different gas saturation in Qinshui Basin. The result shows that the AVO response characteristic of coalbed is different from coalbed methane, the AVO characteristic of coalbed is “dim spot”, and the AVO characteristic of coalbed methane is “relatively bright spot”. This study can provide reliable technical support for the exploration and development of coalbed methane.
