The description for gas bearing interval of Penglaizhen Formation in Luodai gas field.
【摘要】 经过几年的勘探开发 ,证实川西洛带气田的侏罗系蓬莱镇组拥有多层极有潜力的储气层。主要通过气藏模型特征研究、精细地震地质标定 ,证实了蓬莱镇组储气层的强振幅、低频率、低速度特征 ;应用三维立体镂空透视等全三维地震解释方法 ,采用目标层三维地震数据和多井约束三维地震反演数据 ,追踪预测了主要含气储集层的三维空间展布和厚度变化。将地质分析与地震技术相结合 ,预测含气砂体有利沉积相带 ,证明了洛带气田蓬莱镇组属曲流河与网状河沉积 ,研究成果为地质应用取得了良好效果。图 2参 2 (孟宪军摘 )
【Abstract】 It is known that the multi-layered gas reservoirs exist in Penglaizhen member of Luodai gas field, after years exploration and production. In this paper, the author finds out the seismic and geological characters of Penglaizhen member, which are the strong amplitude and low frequency and low velocity,by using gas reservoir model studying and fine match of seismic data with geology data. The 3D distribution and thickness variation of main gas reservoirs are well described by adopting 3D perspective interpretation on the seismic data and well log constrained seismic inversion data. Combining geology analysis and seismic technique together, the favourable sedimentary facies zone is predicted. The sedimentary facies are meandering stream and anastomosed stream. Many research achievements and good geological result are achieved.
