【摘要】 基于三维地震资料,从构造裂缝产生的应力驱动因素出发,采用构造应力场正反演的思路对松辽盆地东部地区火山岩储层裂缝的密度、方位与开启性三项特征参数进行预测并展开分析,结果表明开启性是相对最好的有效储层预测参数。预测结果符合火山岩裂缝发育规律并得到实际资料验证,构造应力场正反演方法可以为有效火山岩储层的预测提供一定的指导。更多还原

【Abstract】 Fracture density,azimuth and openness are predicted and analyzed for the volcanic reservoirs in the east of the Songliao Basin on the basis of 3D seismic data by starting with the stress-driven factor resulted from tectoclase and employing forward and inverse modeling of tectonic stress field. The result shows that openness is the most effective parameter of reservoir prediction. The prediction result coincides with the development of fractures in the volcanic rocks and has been confirmed by actual data. Forward and inverse modeling of tectonic stress field can guide the prediction of effective volcanic reservoirs.更多还原
