层裂

Inadequateness leads to thin artificial barrier, which cannot form a low permeable or impermeable artificial barrier, which just cause lower differential pressure, this cannot control the extension on the height effectively.Moreover, because the artificial barrier cannot achieve the function of the height controlled, finally make the projection less efficiency, even could be defeated comes to an end.

过少则人工隔层过薄，不能形成一个低渗透或不渗透的人工遮挡层，只能在裂缝垂直方向上形成较小的压降，从而不能更有效的遏制裂缝在纵向上延伸；另外，由于遮挡层起不到控制缝高的作用，降低了压裂效率，最终施工效果不明显，甚至会以失败告终。

Summarizing and analysing the stability of stratigraphy and the basic characteristics of geological hazard at the Three Gorges Reservoir,the authors put forward the dangerous slope mainly includes bedding slope,hard and soft rock alternation gentle slope,loose accumulative slop,karst breccia slop and layer cataclastic rock slop.The loose accumulative slopes from Fengjie to Badong are most dangerous and need to control.

在总结分析三峡水库区岩层稳定性及地质灾害基本特征的基础上，根据岩性和结构特征，提出三峡水库区存在较为严重失稳隐患的边坡主要有顺层边坡、平缓软硬岩层互层边坡、松散堆积体边坡、岩溶角砾岩边坡和层状碎裂岩边坡等5种类型，其中分布于奉节至巴东段的松散堆积体边坡危险性最大，是需工程防护的重中之重。

The authors took the Maocaojie section as a typical Permian section, which includes 13 grade 3 sequences that can be divided into two groups: the early craton basin sequences and the late interpolate rifted basin sequences.

以建始县茅草街二叠系剖面为典型研究剖面，将研究区二叠系划分为13个Ⅲ级层序，可分为早期克拉通盆地层序和晚期板内裂陷盆地层序两种类型。

According to the sequence model, the topography is expanse and flatness, there are relative shallow water, stable structure, flattened basement in intercontinental rifting basin, and the provenances changed gradually from terrigenous clasts to intra-basin carbonate. So, there are some corresponding characteristics in sequence genetic framework:① Sequence material components are carbonate rocks, and mixed sedimentary series of carbonate rocks and clastic rocks.

就层序模型来讲，陆内裂陷盆地地势宽缓，具有水体相对浅、构造稳定、基底平缓、物质来源由陆源碎屑逐渐向盆地内的碳酸盐转化，因此，其相应的层序成因格架具有如下主要特征：①在层序物质构成方面，主要由碳酸盐岩构成，其次是碳酸盐岩—碎屑岩的混合沉积岩系。

All the test results showed that this water-in-oil emulsion fracturing fluid posseses such advantages as good themal stability, good shearing stability, low filter loss, low hurt, good restrainting the inflation of clay material, easy breaking of emulsion and flowback and so on, and then it can replace the conventional oil base gel and be used in fracturing the low pressured and strong water sensitive reservoirs of Gars oil field, Qinghai Province.

研究结果表明，该油包水乳化压裂液具有热稳定性好、耐剪切、低滤失、低伤害、能够较好的抑制粘土水化膨胀以及易破乳返排等优点，可以代替常规油基冻胶压裂液用于尕斯油田中浅层强水敏、低压油藏的压裂改造。

If the slope＇s rockmass is low counter-inclined or thick-interbedded with soft interlayer, its failure model is inclined to be tilting-collapsing; if the slope＇s rockmass is homogeneous and thin-bedded with hard discontinuity, its failure model is inclined to be splitting-collapsing; if the slope＇s rockmass is low sequence-inclined with densely deep tectonic joints and weathering fissures, its failure model is inclined to be sliding-collapsing.

当缓倾内层状岩质边坡的岩层较厚，岩性呈软硬互层状产出，或岩层间软弱夹层较厚时，常发生倾倒-崩落式破坏；当缓倾内层状岩质边坡的岩层较薄，且岩性较均一，或层间结构面力学性质较好时，常发生拉裂-崩落式破坏；当缓倾角层状岩质边坡岩层倾向坡外时，在陡倾构造节理和风化卸荷裂隙切割下，常发生滑移-崩落式破坏。

Based on the pennyshaped crack model and the hydraulic fracturing principle,the sand lens reservoir of horizontal occurrence is simplified as a type-I pennyshaped crack of the cap rock. It is due to the fact that the thickness and horizontal distribution length of the reservoir are much smaller than the global cap rock scale. The cap rock fracture resistance of the storage box is analyzed from the view of rock fracture mechanics.

基于币形裂纹模型和水力致裂原理，将纵向厚度和横向展布长度均远小于盖层岩石尺度的水平产状砂岩透镜体简化为盖层岩石中的I型币形裂纹，从岩石断裂力学角度分析封存箱盖层岩石的抗断裂性能。
