摘要
远探测声波测井技术目前正成为复杂油气藏勘探开发的有力手段,而反射方位信息对于储层评价以及工程措施都至关重要。利用集成了测量单偶极不同方位多分量波场功能的多分量远探测声波测井仪器,研究了单偶极远探测联合识别反射方位的方法。由于仪器的影响,单极子不同方位反射波存在振幅差异,据此可以快速判断反射界面方位,但是其准确性依赖于方位接收器个数。偶极SH反射波幅度反映了反射界面的走向变化,但是存在180◦的不确定性。结合单偶极远探测方法的优势,可以快速准确地识别出反射界面方位。理论模拟和实际数据处理表明,两种方法的联合识别,提高了结果的可靠性。
Remote exploration acoustic logging technology is becoming a powerful tool for the exploration and development of complex reservoirs nowadays.The reflection azimuthal information is critical for reservoir evaluation and engineering measures.A multicomponent remote exploration acoustic logging tool which integrating the measurement of monopole and dipole wave field in different directions is used,and the joint azimuth identification methods based on them are studied.Due to the influence of the instrument,the amplitude of monopole reflections in different orientations is different,which could be used to quickly determine the approximate azimuth of interface.However,the accuracy depends on the number of azimuthal receivers.The amplitude of the dipole SH reflection reflects the strike of the interface.But a 180 degrees uncertainty still exists.Combining the advantages of monopole and dipole remote exploration methods,the azimuth of the interface can be identified quickly and accurately.Numerical simulation and field data processing results show that the joint method can improve the reliability of the results.
