An offsef panel display of seismic data has been developed to loca- te shallow drilling hazards. The offset panel displays six sets of common offset, single channel data taken from a conventional marine seimic survey. The single channel profiles are displayed below one another and arranged vertically by offset and horizontall by common depth point. This arrangement causes effects due to nearsurface geologic changes to gene- rate geometric patterns that are different from patterns due to changes in seismic source or receiver. Both reflection and refraction data are used in the display, Reflection data of the near trace or offset are at the top of the display and indicate the presence of acoustic boundaries. Refrac- tions observed on distant traces are sensitive to changes in the near surface. They allow properties of acoustic layers to be determined through their alteration of transit times and amplitudes. A shallow-gas drilling hazard is a low-velocity zone at a depth less than about 700 meters. A seismic reflection from that zone will have a high amplitude. Refractions which transit the zone will be delayed because of low velocity and attenuated because of transmission loss. The offset panel allows correlation of a high amplitude reflection on a near trace with delayed refraction breaks on distant traces thus identifying the hazards. Refractions penetrate to depths of perhaps one fifth of the maximum source to receiver distance depending upon the subsurface velocity distribution .Typical marine seismic surveys with maximum source to receiver offsets of 2700 m permit positive identification of hazards to a depth of about 500 m along the seismic line. The identification of shallow-gas drilling hazards on the offset panel display of conventional data is less subjective than on displays of high re- solution hazard surveys because the identification is based on both high amplitude reflection and delayed refraction. The offset panel may be used to indicate the possible need of a hazard survey. Hazards indicated by the offset panel may be mapped in greater detail by a hazard survey. The offset panel display of conventional data can add significantly to the interpre- tation of shallow-gas drilling hazards.

已研究出了一种地震数据的炮检距汇集图显示方法,并用于确定浅层的钻井危险区。从常规的海洋地震记录取六组共炮检距单道数据显示于炮检距汇集图上,各个单道剖面从上到下一个接一个显示,纵向按炮检距排列,横向按共深度点排列。这样排列使得近地表地质变化的效应产生一些几何图像,它与震源或检波器变化造成的图像不同。显示中不仅利用反射数据,还利用折射数据。近道的反射数据显示在图的上部,用以指出声学界面的存在。远道上观察的折射易感受近地表变化。通过其旅行时和振幅变化可以确定声学层的性质。浅气层钻井危险区是深度小于700米左右的低速区。此区的地震反射有高振幅。穿过此区的折射因低速而有延迟,又由于透射损失而有衰减。由炮检距汇集图可将近道上的反射高振幅和远道上的折射延迟联系起来,从而确定危险区。按照地下速度分布情况,折射穿透深度大约为最大炮检距的五分之一。海上地震勘探中典型的最大炮检距为2,700米,可以肯定地鉴别地震测线上大约500米深度以内的危险区。根据常规数据的炮检距汇集图识别浅气层钻井危险区,比起根据专门的高分辨率危险区调查来说,主观成份要少些。因为前者既根据反射高振幅,又根据折射延迟来识别。炮检距汇集图可用来指出是...

Langfang-Guan region,which is between Beijing and Tianjin,is an area where the geologic structure is very complicated.The litho- logy and age have not been ascertained of a deep horizon (T_6) of the seismic section across No.26 hole in this area.It is necessary, therefore,to make an integrated interpretation of gravitative and seismic data of this line.On this line,the gravity anomaly decrea- ses from northwest to southeast,which shows the linear variation of the regional gravity field in this area.Having maed forward and inverse computations of gravity anomaly by coresponding seismic interval velocity,geologic section and depositional facies section, we find that the factor causing gravity anomaly is notunique,in other words,the main density boundary causing gravity anomaly is not a single one,so,it can not represent the undulation of the basement.However,the density calculated from T_6 horizon nearby No.26hole is 2.67g/cm~3,which is approximate to that of limestone. it is thus inferred that T_6 reflection comes from the top of Car- boniferous-Permian limestone.

北京和天津之间的廊坊—固安地区是一个地质构造复杂的地区。对于通过该区泉26井的一条地震剖面上的深部反射层(T_6)的岩性及时代的解释,尚有争议,故希望通过与此地震测线重合的重力剖面,进行联合解释。该剖面上的重力异常值由西北往东南单调降低,反映该区的区域场具有线性变化的特点,利用地震层速度、构造剖面和相剖面等资料进行重力异常的正、反演计算,其结果说明引起重力异常的因素不是单一的,也就是说,产生重力异常的主要密度界面不是一个统一的地质层位,它不能反映基底界面的起伏。但是,在泉26井附近,依据 T_6反射层换算的密度值为2.67g/cm~3,接近石灰岩的密度值,故推断 T_6反射波相当于石炭—二叠系石灰岩的顶面反射。
