【摘要】 近年特殊的地震处理技术和油气储层预测技术不断地发展和应用,90°相位转换和波形分类技术就是其中之一。90°相位转换的目的是将地震反射的主要同相轴与地质上的薄砂层中心对应,使地震相位具有岩性地层的意义;与传统地震相划分相比,波形分类最大优点是在没有更多井资料的情况下,充分利用丰富的地震信息,快速确定目的区域的异常特征后结合各种地质成果进行更细致的研究。应用该技术对贝西北地区的河道和砂体展布进行预测,在结合典型井和地震响应特征的基础上,准确的刻画了河道的平面分布形态,实现将地震相图转换成储层沉积微相图,为今后的布井提供了可靠的依据。更多还原

【Abstract】 In recent years,special seismic processing technology and oil and gas reservoir prediction technology are continuously developed and applied,90 ° phase conversion and waveform classification techniques is one of them,90 ° phase conversion objective is make seismic reflection in-phase axis and the center of major geological thin sand layer correspond and make the seismic-phase have the lithological formations significance; compared with the traditional division of seismic facies,The biggest advantage of waveform classification is no more well informed,fully utilizing the wealth of seismic information,quickly identify the purpose of the abnormal characteristics of the region after the combination of geological results of more detailed study. The technique is applied to predict channel and sand body in the northwest of Beier area.On the based of combining the typical characteristics of wells and seismic response,an accurate portrayal of the river flat distribution patterns is achieved the phase diagram converted into seismic reservoir sedimentation micro-phase diagram and provide the evidences for drilling disposition.更多还原
