【摘要】 传统以二维地震剖面资料为主的断层解释方法对低序级小断层、复杂断裂带断层空间组合关系识别精度较低,解释周期相对较长,难以满足大庆油田密井网条件下特高含水期剩余油精细挖潜的需求。针对这一实际,从三维可视化井震匹配断层解释方法和方差体、蚂蚁体等技术入手,结合井钻遇断点情况,在三维空间多方位、多角度对断层进行井震匹配及三维立体精细解释,提高了断层解释效率及精度,研究成果在指导油田开发调整及优化井位设计等方面取得较好效果。

【Abstract】 Traditional seismic interpretation that mainly used 2D seismic profile data for low order small faults and the complex faults are inaccurate.The interpretation cycle is very long.It is difficult to meet the demand of residual oil fine potential tapping un der the condition of high well-density in Daqing oilfield in high water cut stage.Therefore,started with 3D visualization well-seis mic match fault interpretation methods,variance cube and ant cube,combined with well fault points,this paper carried out the well-seismic match of faults and the fine interpretation of 3D in multi-faceted and multi-angle 3D.This method improved the effi ciency and the accuracy of fault interpretation.The research results have been widely used in the oilfield development adjustment and optimization of well location design,and achieved good effects.
