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 )
After several years of exploration and development, it was confirmed that the Jurassic Penglaizhen Formation in the Luodai gas field in western Sichuan has multiple layers of potential gas reservoirs. Mainly through the study of gas reservoir model characteristics and fine seismic geologic calibration, the characteristics of strong amplitude, low frequency and low velocity of gas reservoirs in Penglaizhen formation are confirmed. The 3D seismic data, such as three-dimensional hollow skeleton, And multi-well constrained 3D seismic inversion data to track and predict the three-dimensional spatial distribution and thickness variation of the major gas-bearing reservoirs. The geological analysis and seismic technology are combined to predict the favorable sedimentary facies belt of gas-bearing sandstone. It is proved that Penglaizhen Formation belongs to the meandering river and reticular river sediment in Luodai gas field, and the research results have achieved good results for geological application.
