There are four kinds of fault, according to geometric character of fault, which are deep-seated fault, the fault surface cross cap formations but is not reach to ground, the fault surface cross to ground and ground fault. Discuss the closure ability, based on the active stage and the lithlogic of two sides in fault.

根据断层几何学特征和成因历史分为四类：深部断层、断穿盖层未至地表断层、通天断层及表皮断层，以其活动时期和断层二盘岩性特征为基础，分类讨论了封堵性。

This makes more and more people pay more attention to studies and applications of numerical simulation in thermal recovery. In this research, we have developed a reliable mathematical model for thermal recovery, which takes a full consideration of the effect of viscos, gravitical and capillary forces on the three-phase flow of gas, water and oil, the effect of the temperature on the medium characteristics of liquid and solid, the phase equilibrium of gas-liquid in each component, heat transportation including connection, conduction and radiation as well as heat losses in both the overburn and underlying strata. In the space discreation of the mathematical model, we have proposed a new method based on the improvement of the conventional nine-points difference approximation, which has a higher difference accurancy.

本项研究以热力采油的主要机理为基础，充分考虑在粘性力、重力和毛管力作用下油水气三相流动，考虑温度对各种流体和固体介质物性的影响，考虑每一组分中汽液两相的相平衡，考虑热在地层中的传导、对流和辐射以及上下盖层的热损失，利用热力学第一定律、质量守恒定律和流体迁移定律，建立了正确可靠的注蒸汽数学模型；在对数学模型进行空间离散时，利用控制有限体积积分法，对以往的九点差分近似作了合理的改进，使其具有较高的差分近似精度：结果表明，该公式的近似精度要比以往文献中所给的九点差分近似精度高，可以认为，在油藏数值模拟中，如果遇到非均质情况，使用这种九点差分近似更合理。

The unit bottom was the unconformity developed by Wuling Movement, and the unit top was overlapped by glacial deposition of Nanhua System. What\'s more, an unconformity can be found in Northern Guizhou and North-western Hunan. At the same time, this boundary was an important transformation between different deposition types: Banxi Group was rift basin deposition with flysch suite, and bearing a vast amount of pyroclasts, and this suggests that there was strong activity of crust. But the overlapping glacial deposition stood for steady deposition with penecaprock characteristic, and under unique climate environment.

下为武陵运动形成的角度不整合面所限；其上被南华冰期沉积所超覆，在黔北—湘西北可见角度不大的不整合，而且这一界面是两个不同沉积类型或建造之间的一个转换：板溪群为具有复理石韵律的裂谷系充填，其中发育大量火山碎屑沉积，显示较强的地壳活动性；而上覆的南华冰期沉积所代表的是一个具有准盖层性质的、独特气候环境下的稳定沉积。

In the foreland basement-involved structures, although the considerable relief bewteen the hanging wall and footwall may exist, the cover strata probably keep continuous.

在有基底参与的冲断构造带中，尽管上盘与下盘有较大的构造高差，但盖层完全可能是连续的。

All kinds of sands and source rock could develop two kinds of accumulation models of graben and horst, forming lots of blind strtigraphic traps.

各种类型的砂体沉积和烃源岩以及盖层可以在空间上形成半地堑和地堑两种成藏模式，发育众多的隐蔽岩性地层油气藏。

A typical feature of Dongpu depression is that 4 sets of halite are vertically developed in the north,which forms the favorable cap of hydrocarbon accumulation.

摘要东濮凹陷的一大特点是其北部纵向上发育4套盐岩，它们构成油气富集的优良盖层。

In the first exploration stage,several plays were divided vertically in order to show the characteristics of petroleum accumulation more clearly.With the assurance of source rock,the main play and prospect targets were chosen quickly by the assessment of reservoir,cap rock,migration passageway,seal ability of the faults,structure characteristics,favorite traps and the allied conditions.Good exploration result has been obtained in Melut Basin.
