砂层组
1.
First,based on fine well-to-seismic calibration,isochronal layer structure was established through seismic and datum bed control; Then,the sand sets were correlated in stratum fra.
为此,提出了井震联合分级控制小层对比方法,即首先在精细井震标定的基础上,利用地震资料和标准层控制,构建大套地层等时格架；然后运用相序递变规律、沉积旋回和反演结果在地层格架内对比砂层组；最后利用模型以及岩性和厚度比例对比单砂层。

The basic principles are that 1)seismic data and logging data are used to inverse the wave impedance of sand set,2) the wave impedance of the sand set is corrected to remove the effect of mudstone,and 3)the wave impedance after correction(the wave impedance of sandstone)is used to calculate the porosity.
方法的基本原理是:首先利用地震、测井等资料,在精确层位标定的基础上,进行波阻抗反演,得到砂层组的波阻抗;然后对砂层组的波阻抗进行校正,去除泥岩的影响;最后利用校正后的波阻抗(砂岩波阻抗)计算孔隙度。

密切关系。流砂层岩性特征是，般砂粒粒度均匀孔隙度大、上下岩层多为不透水性。故常饱含地下水;粘土质流砂层具触变性，即受机械振动而液化，振动停止后又恢复原状;天然流砂层湿而带腐臭味。形成流砂的原因:吃l、山于地下爆破或机械震动的影响.在足够大的动水压力或动荷载作用「，层中水力坡度增大，流速增大，冲动细颗粒而使其悬浮和流动成渗透流砂(助由土粒周围附着亲水胶体颗粒，饱水时胶体颗粒膨胀·在渗透水作用下而悬浮流动;其流动速度有快有慢遇到以溃决形式急剧流动时，破坏力很大，会使地基和「_程的稳定性遭到严重破坏。流砂层它是矿山采掘作业的 ，大灾害其防治方法有疏干排水、灌浆固结、板桩加固等 (李远鄂陈国洗l一ushoeeng流砂层(quiek sand bed)埋藏于地下饱含水的，当工程揭露时引起渗透水流作用而发生流动的粉砂、细砂、亚粘土层。流砂层不仅分布于第四纪地层中，而且在基岩古老时代的地层中也有存在，它埋藏于不同的深度，其分布位置多与古河谷和近海冲积平原有
