In forward simulating a complicated steep structure on a minicomputer, a geological section may be expressed by finite elements, and the configuration of reflectors can be fitted by means of Lagrange's second order interpolation formula, The initial forward model may be designed by using image ray tracing method based on actual data, According to the degree of conformability between the forward simulated section and corresponding actual stacked time section, the configurations of reflectors within the model can be layer by layer modified from shallow to deep until the simulated time section most resembles the corresponding stacked time section, The best forward simulated section is thus the very geological section we seek.

在小型计算机上对复杂陡构造作正演时,可用有限元素表示地质剖面;用二次拉格朗日插值公式拟合反射界面的形态。初始的正演模型可根据实际资料采用成像射线跟踪法设计。依据正演结果和实际的迭加时间剖面吻合程度,由浅至深一层一层地修改模型各反射界面的形态,直到由模型作出的时间剖面最佳地逼近迭加时间剖面。此时,所得的正演模型即为求解的地质剖面。

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.

本文阐述了射线法三维正演模型技术的方法与原理,包括三度空间地震界面的数学模型、射线轨迹的计算、零炮检距时间剖面的合成。模型计算中考虑绕射、回转模拟,并考虑单震源、多震源、常速、变速等情况。文中提到的用于带断层界面拟合的FWJQ法及用于射线追踪的投影搜索交点法是可行的。所述射线法三维正演模型技术应用French模型检验效果良好。江汉油田GN工区三维实际模型的解释表明经过调整的前三层界面(Q底、EL_1、T_2)与原始水平叠加剖面有良好的一致性,合成剖面T_5界面的反射波组基本合理,但在断点位置上仍有差异。总之,试算结果使我们对三维地质体速度的认识及速度参数的提取产生了新的思路,试验对三维模型技术的应用研究是有参考价值的。
