It is of great significance to establish mathematical model of lacustrine delta for prospecting and developing the continental oil and gas fields. In the proposed model of lacustrine delta,cross-section of river bed is taken as a rectangle,the river month is considered as a sprayer,and the water flow from the riv- er into lake will be simulated by a free jet.Because downstreams of the most natural rivers are in the form of open-flow,the center flow line on the vertical section will be regarded as a 2-dimensional...

It is of great significance to establish mathematical model of lacustrine delta for prospecting and developing the continental oil and gas fields. In the proposed model of lacustrine delta,cross-section of river bed is taken as a rectangle,the river month is considered as a sprayer,and the water flow from the riv- er into lake will be simulated by a free jet.Because downstreams of the most natural rivers are in the form of open-flow,the center flow line on the vertical section will be regarded as a 2-dimensional plane jet when the water flows into the lake.Take the calculated velocity-distribution along the center profile along the direction of flow bo- undary condition for such 2-dimensional jet,velocity components in the direction of the water flow and those along the river section transversely can be determined.If the debris carried by the river are regarded as ideal particles,and then the deltaic bo- undary,morphology in vertical section,and change of sediment sorting,under different hydrodynamic conditions of the river and lake,are calculated by the same tracing me- thod used in ballistic missile. The characteristics of lacustrine delta shown by mathematical model can be used in studying modern and ancient delta.

建立湖泊三角洲数学模型,对陆相油气田的勘探与开发工作具有重要意义。在湖泊三角洲模型中,假定河床横剖面为矩形,将河口比拟为一个水动力学上的喷咀,河水入湖形成自由射流。由于多数天然河流下游均呈开放性,所以,入湖后流向中心线纵剖面上的流动可以看作二维平面射流。将求得的中心纵剖面上沿河流向速度分量做为求解水平二维平面射流的边界条件,就可得到沿河宽方向速度分量和沿河流流向的速度分量。如果把河流携带的碎屑物看作理想颗粒,则就可采用与弹道式导弹相同的跟踪方法,求出不同河湖水动力条件下三角洲边界、纵剖面形态和沉积物分选性变化。用数学模型揭示湖泊三角洲特征,可以作为研究现代、古代三角洲的借鉴。

Necessity, technique meaning, and thoughts of well log constrained seismic inversion are expounded in this paper. The developing course of well log constrained seismic inversion is reviewed. After three nonlinear methods of well log constrained seismic inversion are compared, the result is that wavelet transform has more potential and deserves to lucubrate. Present research situation of well log constrained seismic is summarized briefly, and it can be pointed out that our research object is turned to marine...

Necessity, technique meaning, and thoughts of well log constrained seismic inversion are expounded in this paper. The developing course of well log constrained seismic inversion is reviewed. After three nonlinear methods of well log constrained seismic inversion are compared, the result is that wavelet transform has more potential and deserves to lucubrate. Present research situation of well log constrained seismic is summarized briefly, and it can be pointed out that our research object is turned to marine complex carbonatite geologic body. The technique will meet good opportunity and challenge because continental and marine oil and gas field differ in many ways. Finally, the developing direction of well log constrained seismic inversion is pointed out.

 阐述了测井约束地震反演研究的必要性、技术内涵及研究思路,回顾了测井约束地震反演技术的发展历程,比较了三种非线性测井约束地震反演方法的优缺点.小波变换以其独特的变时窗特性,在测井约束地震反演技术发展中潜力较大,值得深入研究.同时对测井约束地震反演技术的研究现状做了小结,指出当前的研究对象已转向了复杂地质体,特别是海相碳酸盐岩复杂地质体,由于海相和陆相油气田存在许多不同之处,所以测井约束地震反演技术将面临巨大的机遇和挑战.最后,指出了测井约束地震反演技术的发展方向.

There are numerous oil and gas fields in north and northeast China. Based upon gravity data and ge-ochemical features of hydrocarbons, it is suggested that the formation of oil and gas be linked to sub-mantle plumes and mantle plume branches. The formation of hydrocarbon reservoirs is influenced by a series of mantle rising, geothermal gradient increase, crustal subsidence, organic accumulation and sedimentation of volcanic-sedimentary sequences. It can also be proved by deep-seated source and non-hydrocarbon...

我国东北及华北地区是中、新生代陆相油气田集中分布域。通过对物探重力勘查和油、气的地球化学分析等资料研究,初步认为油气田的形成是与亚幔柱及幔枝构造密切相关。石油的成藏作用是受地幔隆升、地温梯度增高、地壳下隆、生物繁殖、广泛有火山-泥砂质沉积建造诸因素控制,天然气的深源非烃气成因更可获得佐证。
