First, from the macro view of gaswater distribution and movement law, the formation mechanisms of edge water, inlayer water and interlayer water, as well as the three basic models of water breakthrough in gas wells were analyzed. Then from the microscopic angle, this paper studied the reservoir pore structure and rock wettability of loose sandstone gas reservoir, and analyzed their control effect on gas reservoir's original gaswater distribution.

首先从宏观气水分布及气水运动规律的角度出发，分析了边水、层内水、层间水的形成机理和气井见水的3种基本模式；然后从微观角度，对疏松砂岩气藏的储层孔隙结构及岩石润湿性进行了研究，分析其对气藏原始气水分布的控制作用。

Since there\'s inlayer heterogeneity in layered sandstone reservoirs and remaining oil potentials are mainly in thin or poor layers, which are mostly in delta front facies growth, this paper studies physical characteristics parameters interpretation methods for delta front deposit reservoirs to deepen the acknowledge to the depositional modes and features for further implementing the develop adjustment potentials and optimizing the potential tapping adjustment patterns. This practice has an important guiding sense to enhance the ultimate production recovery for mature oilfields.

我国大多数主力油田都属于陆相河流—三角洲沉积储层，如大庆的喇嘛甸、萨尔图和杏树岗等油田，这些油田基本上均已进入高含水后期开采阶段，尤其是以河流相发育为主的主力油层综合含水已达到90%以上，由于多油层砂岩油田存在层间的非均质性，油田的剩余油潜力主要集中在以三角洲前缘相发育为主的薄、差油层中，因此研究三角洲前缘相沉积储层的物性参数解释方法，深化其沉积模式及沉积特征的认识，进而落实油田开发调整潜力，优化调整挖潜方式，对提高老油田最终采收率具有重要的指导意义。

Multi-level heterogeneous sandstone oil-gas reservoirs have many characters: the layer systems are numerous, the interlamination contradictions are predominant,the reservoir anisotropies are greatly severe et al.

多层非均质砂岩油气藏具有层系多、层间矛盾突出、储集层非均质性强等特点。

The Boulder Opal comes from Queensland, Australia, and is found in the cracks of ironstone or sandstone boulders.

蛋白石的博尔德来自澳大利亚昆士兰州，并在砂岩的铁矿石或石头的缝隙中。

Both the Staithes sandstone formation and Cleveland ironstone are visited at a number of localities.

对许多地方的Staithes沙岩构成和Cleveland铁矿石进行了访问。

It is an important content of sequence stratigraphy applying in exploration practice that predicting distribution of sandstone through using the seismic data to study deposition spatial distribution, superposition style and sediment evolution in the various system tracts on the basis of isochronal sequence framework.

在等时层序格架建立的基础上，利用地震资料研究各体系域内部沉积体的空间展布、叠置样式和沉积演化过程，进而预测各体系域中砂体的分布，是层序地层学应用于勘探实践的重要内容。

The correlative coefficients of linear regression function for isochronous stress-strain curve are all higher than 0.92, and the ratio of long-term strength to instantaneous strength reaches 94.39%, which indicate that the whole creep of fine sandstone specimen is weak.

应力－应变等时曲线线性回归函数的相关系数均高于0.92，长期强度与瞬时强度之比达94.39%，证明细砂岩试样的整体蠕变特性不强。

The average correlative coefficients of linear regression function for isochronous stress- axial strain curve are 3.92% higher than that of average correlative coefficients of linear regression function for isochronous stress- radial strain curve, so nonlinear creep property of the fine sandstone specimen in axial direction is correspondingly weaker than that in radial direction.

应力－轴向应变等时曲线线性回归函数的平均相关系数高出应力－径向应变等时曲线线性回归函数的平均相关系数3.92%，因此其轴向非线性蠕变特性相对于径向非线性蠕变特性更弱。
