| 摘 要： | 针对大芦湖地区沙三中、下砂体上覆高速火成岩体与巨厚高青砂岩体的地质特征，利用大芦湖地区测井、钻井、地质等资料相结合，寻找高青大砂体的分布规律，形成了一套解释樊家砂体成因的理论：块体滑塌理论。并且利用该区的声波测井及速度谱资料，分析该区特殊地质体、储层、围岩层速度及平均速度变化，采取相应措施提高沙三中、下砂体识别能力并准确地进行砂体等时图时深转换。在测井约束反演时，为了消除目的层上部的高速地质岩体的屏蔽作用，对测井声波作了预处理，相应地提高了目的层的速度，从而突出目的反射层阻抗界面。使用预处理的声波，进行多井约束反演，目的层清晰，基本消除了上覆高速地质岩体的屏蔽作用，因而有效地提高了目的层砂三中、下砂体的识别能力。

| Abstract: | The distribution regularity of the Gaoqing sand body was unravelled and a special tyeory for the genesis os sand body was established on the basis of geological characteristics of the igneous rock and thick bedded sandstone overlying on the middle and lower sand bodies of the Sha Member,and of various data of well logging,drilling and geology.The variation of and average velocity of the special geological body,reservoir and country rock was analyzed in reference to the data of sound logging and velocity spectrum.Corresponding measures were taken to increase the discernment of the middle and lower sand bodies of the Sha Member.In the restriction inversion of logging,the logging sound was pretreated so as to remove the shield effect of high velocity geological body on the objective horizon.Thus,the veolcity of the objective horizon increased and the impedance boundary of the objective reflecting horizon became obvious. |
