| 海中地区火成岩发育,为含油层序,但地震地质条件复杂,受火成岩影响资料品质较差,火成岩与地层解释有较大难度。笔者应用测井、地球物理方法结合钻井资料,重点介绍利用火成岩的高速、高阻抗特征,应用STRATA测井约束反演对火成岩进行地震识别;应用EMERGE孔隙度反演技术,预测火成岩厚度与孔隙度。 |

| Abstract: |
| The Haizhong region in northern Jiangsu Basin is characterized by oil-bearing igneous rock (sequences). However this region is geologically and seismically variable due to the existence of numerous faults and fractured structures, and thus may be problemable in the interpretation of the volcanic rocks and stratigraphy. The (present) paper deals with the seismic recognition of the igneous rocks in the light of high velocity and high resistivity of the igneous rocks by using STRATA well logging inversion technique, and prediction of thickness and porosity of the igneous rocks by using EMERGE inversion technique. |
