克拉美丽气田石炭系火成岩储集层空间分布复杂,以往的地震资料由于信噪比偏低,分辨率不高,石炭系内幕成像不清楚,根据地震解释结果部署井位有一定风险.应用连片三维地震数据体经过叠前时间偏移处理,提高了信噪比和同相轴连续性,石炭系顶界波组反射清楚,内幕及岩相特征明显.通过地震精细标定,应用地震属性分析并结合钻井、测井等资料,基本确立了滴西14、滴西18井区石炭系火成岩的发育模式和展布形态.同时,使用SMT软件对石炭系储集层进行描述,清楚地刻画了有利的火成岩岩体分布特征,为下步开发方案的制定提供了可靠依据.

Kelameili gas field in Junggar basin is rich in oil and gas resources of Carboniferous, but its igneous rock is complex in the spatial distribution of reservoir. Based on the previous seismic data and existing seismic interpretation results, there is a risk of arrangement for production well due to low signal-to-noiso ratio, limited resolution and unclear image in interior of Carboniferous. Using linked 3D seismic data volume that is processed by pre-stack time migration, the signal-to-noise ratio and the event continuity can be improved, and the composite wave reflection of the top interface of Carboniferous becomes clear, with distinct characteristics of its interior and lithofacies. This paper presents the development and distribution patterns of the Carboniferous igneous rock in Well Block Dixi-14 and Dixi-18 by fine calibration, the seismic attribute analysis and integrating with drilling and well logging data. Also, this paper describes the igneous reservoir of Carboniferous using SMT software, showing the distribution characteristics of favorable igneous rock body, which provides reliable foundation for the implementation of next development program.
