HXC气田蓬莱镇组气藏河道砂体快速识别研究

IDENTIFICATION AND STUDY OF THE RIVER SAND BODY OF J_3p POOL IN HXC GAS FIELDS

仅仅 1 0 0～ 3 0 0 m宽的河道砂体的快速识别对于降低勘探开发成本 ,提高经济效益具有重要的作用。基于对川西坳陷 HXC气田蓬莱镇组碎屑岩气藏河道砂体的气藏特征的解剖和地球物理响应模式的建立 ,利用先进的三维可视化技术快速地识别了气藏的河道砂体 ,部署的钻井获得了勘探新突破。该方法在中国广泛的陆相地层中具有较高的推广价值。

This paper describes in detail the method to identify the river sand body of J 3 p pool in HXC gas fields. This method consists of the analysis of pool characters, the establishment of the model, and the quick identification of the river sand body by 3 D visualization soft. Based on this study, the exploration and production cost is reduced, and the economical benefit of the fields is improved.
