地震技术在火成岩发育区开发中的应用

Application of seismic methods in the development of igneous rock reservoirs

根据GY凹陷北斜坡SN油田火成岩发育的特点 ,围绕火成岩干扰对构造解释的影响问题 ,应用层位标定、地震属性描述、模型正演及测井约束反演等地震技术 ,对构造区火成岩地震属性特征和分布规律进行了深入研究 ,极大地消除了火成岩干扰对构造解释的影响 ,取得了较好开发效果。

According to the characteristics of igneous rocks in the north slope of GY sag, SN oilfield, the author studied seismic signatures of the igneous rocks and their variability with seismic methods with the emphasis on impact of the igneous rocks to seismic interpretation. The methods used in the study include horizon calibration, seismic attribute description, forward modeling, and log constrained inversion. The impact of the igneous rocks to seismic structural interpretation was greatly reduced, which yields satisfactory development effects.
