This paper describes some essentials of 3-D ray-tracing modeling technique, which are the 3-D mathematical model of seismic reflectors, the computaton of ray path, the synthesis of zero-offset time section, and so on.Some factors, such as diffraction, reverse reflection branch, single source, multiple sources, constant velocity, varying velocity etc, are taken into consideration in the calculation of model.The FWJQ method for fractured reflector fitting and the ray projection method for seeking the intersecting points are feasible.The fine feasibility of 3-D ray-tracing modeling technique has been proved by French model.In the 3-D modeling of the geology of GN prospect in Jianghan oil field, a good correlation is obtained between the modified Q(base- ment), EL_1, T_2 reflectors and the corresponding reflectors of horizontal stacking sections; and the reflection band of T_5 reflector on synthetic seismic section is quite reasonable except fracture positions.In summary, this trial 3-D modeling technique leads to a new idea in analysing 3-D velocity, it is also significant to the research on applied 3-D modeling.

It is not only economical but also greatly significant in science to use gravity data to infer crustal thickness and make the research of seismogenic and mine—growing environment where it is impossible to perform DSS work in a large scale. In order to remedy the defect of using mean field, analytic continuation, frequence filtering method and 2—D computational method, in this paper, the deep gravity anomaly has been obtained based on the gravity data and petroleum exploring data in the juneture region of Henan Shandong and Anhui provinces (E114-116.5, N32.5-36.5)and by calculating the influence of shallo layers by 3—D computation method and eliminating it from Bouguer gravity anomaly.Then the repeated forward computation and the inversion of anomalous interface approximation are used to get the optimal crustal thickneess. The double MSE of the calculated crustal thickness is less thn 1km. The result coincides with that from DSS quite well, the difference less than 2km. A preliminary study is also made on the relationship between earthquake distribution, oil field, natural gas field and the crustal thickness.

在人工地震测深工作尚不能大面积开展的地区,利用重力资料推断解释地壳厚度的平面分布,来研究地震孕育和矿藏生成的深部环境,是一项既经济又具有科学性的工作。为了弥补采用平均场、向上解析延拓和频率域滤波等方法以及采用二维计算方法的不足,本文依据豫鲁皖部分地区(东经114°~116.5°,北纬32.5°~39.5°)的重力资料和浅部地质、物探资料,采用三维正演方法分别计算浅部各层密度界面产生的重力异常,并从布格重力异常中消除其影响,得到剩余深部重力异常;然后采用多次正演计算和异常曲面逼近的反演方法,求得该区地壳厚度的最佳分布。用重力反演方法得到的地壳厚度,2倍均误差小于1公里。与人工地震测深剖面对比,两者的起伏形态基本一致,相差一般不超过2公里。本文最后指出了震中位置相石油、天然气与地壳厚度的空间对应关系,并作了初步分析。
