井旁裂缝的声场模拟及反射波提取方法
Keywords: 声波测井,井旁裂缝,声场模拟,反射波,波场分离,阵列组合
Abstract:
?针对现有阵列声波测井仪器,对井旁不同角度和不同位置裂缝的全波波列进行了数值模拟。结果表明,在现有仪器源距范围内,地层滑行纵波和滑行横波之间可能观测到清晰的反射纵波,而反射横波以及转换波由于到达时较晚,被湮没在滑行横波以及斯通利波中;对于水平缝或低角度缝,在全波波列中可观测到直达斯通利波和反射斯通利波。在此基础之上,以线性预测理论为基础,本文提出了-种适合于阵列声波测井测量方式的反射波提取方法,该方法有别于传统的波场分离方法,可针对阵列声波测井数据的特点有效地将反射波提取出来。特别是通过对不同的阵列数据进行道集组合,分别将上行反射波和下行反射波分离,进-步对反射波数据进行叠加,可增强反射波信息,提高信噪比。通过对现场实际数据进行处理,搞清了井旁附近的地质构造特征,验证了该方法的有效性和实用性。
