摘　　要：静校正工作在地震资料处理中是一项非常重要的基础工作 ,常规的静校正方法均存在一定的误差 ,不能满足高分辨率地震勘探的要求。而微测井技术能够提供一个较精确的静校正量计算方法 ,因此在微测井正演理论模型的基础上 ,给出了野外微测井资料采集方法 ,在取得微测井低速带、降速带厚度及速度数据后 ,计算出精确的静校正量并用于叠加处理中 ,从而保证了地震波的同相叠加。用该方法做出的叠加剖面连续性好 ,分辨率和信噪比也比较高 ,有利于微幅度构造和小断层的识别。实际资料处理实践证明 。Static correction is a very important work during seismic data processing ,the error of conventional static correction method can't be satisfied with the requirement of high resolution seismic exporation.Micro logging technique can provide a accurate method estimating static correction data .Therefore,on the basis of micro logging forward theory model,its field acquisition method was designed ,after micro logging's low velocity an dropping velocity zone data were estimated accurate static data were calculated,then it was used during stack processing,so same phase of seismic waves is guaranteed.Continuity,resolution and S/N of stack sections by using this method,it is useful for recognizing micro closure height struture and small fault.This method is feasible through practice data processing proved.
