XRD and SEM analysis showed that the main composition of the white substance which formed in cracks is CaCO3, which can block cracks and is probably the main cause of self-sealing. Two processes which called surface reaction process and diffuse reaction process are defined in the formation process of CaCO3.The phenomenons in self-sealing experiment can be explained by those two processes.

对试件裂缝中沉积的白色物质做SEM、XRD分析得出其成份主要为CaCO_3，CaCO_3堵塞裂缝应该是引起自愈现象的主要原因；CaCO_3的生成包括表面反应和扩散反应两个阶段，这在一定程度上解释了自愈现象先快后慢和自愈幅度砂浆＞混凝土＞净浆。

Evaluating three fracture models and the result of electrical analogy. electrical analogy to the production potential of vertical fractured wells is a kind of analogy between mechanism modeling and scale modeling, the result of it is approximative and the shape of the curve is relatively good, but it is relatively bad in quantification, it can be replaced by the result of mathematic simulation.

对三种裂缝模型以及电模拟结果进行了理论评价，认为对垂直裂缝井产能的电模拟是一种介于机理模拟和比例模拟之间的模拟，其给出的模拟结果是近似的，曲线形状比较好，但定量结果比较差，可以通过建立数学模型，用数学模拟结果取而代之。

数值分析中将多边形网状分布的裂缝简化为轴对称问题，对土骨架采用弹塑性的双硬化模型进行描述，并分析了不同参数对裂缝宽度和深度影响的敏感性。

Standard of ornamental design acceptance of work: Ornamental design project is finishing dry hind, just can check and accept; Check and accept ornamental design project, whether does the breed that should check ornamental design, norms, design accord with design requirement; Ornamental design should be installed firm, its quality asks to reach tolerance, should accord with: The level of form ornamental design and perpendicular tolerance, every meters must not be more than 5 millimeter, must not be more than 3 millimeter endlong; The tolerance of position of alone ornamental design, must not be more than 10 millimeter; Ying Guangjie of ornamental design surface, design clarity, juncture rigor, must not interstitial, warp, edge damage drops the blemish such as horn; Back up spends exterior Ying Guangjie, design clarity, without break.

花饰工程验收标准：花饰工程完工并干燥后，方可验收；验收花饰工程，应检查花饰的品种、规格、图案是否符合设计要求；花饰应安装牢固，其质量要求及允许偏差，应符合：条形花饰的水平和垂直允许偏差，每米不得大于5毫米，全长不得大于3毫米；单独花饰位置的允许偏差，不得大于10毫米；花饰表面应光洁，图案清晰，接缝严密，不得有裂缝、翘曲、缺棱掉角等缺陷；裱花表面应光洁，图案清晰、无裂缝。

Application to the Eopalaeozoic buried hill in the Z oilfield shows that the two types of azimuthal attributes, attenuation gradient and frequency at 85% energy ratio, are closely related to fracture characteristics of carbonate reservoir.

对Z区下古生界潜山碳酸岩储层进行的裂缝预测表明，由衰减梯度和85%能量比频率两种属性导出的裂缝发育密度具有很好的相关性，且与实际情况符合。

Because of increase of the oil-gas production of fractural reservoir, fractural reservoir is more and more important in the petroleum industry in China.

在我国，随着裂缝性储层油气产量的逐渐增加，裂缝性储层在我国的石油工业中占有越来越重要的地位。

If using humidly hardener, the surface can be humid, but there should not be any panice. b the surface should be fastness, compact and smooth, without any sand streak, floppy shell, crack, comb,bug holes. Using light blasting spray to clean the unevenness and incompact raffle, and getting the appropriate roughness, filling the crack with HF61-30 mixed with fine sand. C the surface must be clean, and have no oil stain.

如采用湿固化涂装，则表面可潮湿但不能有浮水。b水泥表面应坚固、密实、平整，不能有起砂、起壳、裂缝和蜂窝麻面等现象，可采用轻喷砂法除去水泥面上的不平整和不结实的杂物，并使其具有一定的粗糙度，对裂缝可使用HF61-30添加适量细砂填补。c表面必须清洁，须除去表面油污。
