摘　　要：单井反射声波远探测成像技术是近年来石油勘探研究热点之一,其中一个重要进展就是利用偶极横波对井旁的地质构造进行反射波成像。该技术不仅可以得到井旁反射体的空间位置,同时也可以通过四分量数据旋转,得到井旁反射体的走向。基于偶极横波远探测基本理论,开发出了偶极横波远探测测井资料处理技术,形成了一套快速有效处理偶极横波远探测测井成像资料的流程。该技术能够有效探测储层中的井旁地质构造,计算速度较快,能够满足现场数据处理的需要;对于非常规储层,例如致密砂岩、碳酸盐岩储层等的探测也同样有效,可以为井旁储层结构的精细探测提供依据和技术支持。An important recent advance in single-well acoustic reflection imaging is the utilization of a dipole acoustic system to image the geologic structure around the borehole in formation,which has become one hot spot of researches in oil exploration.The technology not only can determine the space position of reflector,and can get the strike of the reflector through rotating four component data.On the base of the dipole shear-wave imaging basic theory,we developed the dipole shear-wave imaging processing technology,and formed a fast and effective dipole shear-wave far detection imaging work procedure.The processing results demonstrate that this technology can effectively detect the borehole geologic structure in reservoir and meet the needs of field data processing.The processing techniques are reliable and effective.For unconventional reservoirs,such as tight sandstone and carbonate reservoir,the technique is also effective.It can provide technical support and basis for further fine exploration and development of reservoir structures.
