This research shall be obtain that ocean-sand motor shall have more compressive strength early, but later strength shall descend, by means of non-standard sand mixing sample is quite obvious. By means of 50% ocean-sand substitutes for river-sand to mix fine aggregate compressive strength early shall be risen 20%~30%; Adds slag to ocean-sand or a half of river-sand and ocean-sand to make motor test sample, Compressive strength、bending strength and tensile strength shall be according to slag additament, by means of. slag add itament substitutes for cement 40%~60% is most. But slag be able to substitute for cement is too enough, 1ater strength shall be descent.

由本研究可得知海砂拌和的水泥砂浆，其早期抗压强度较高，而晚期强度则有下降的趋势，其中以非标准砂拌和效果最为明显；若以50%海砂替代河砂做为拌和细骨材，其早期抗压强度约上升20%~30%；添加炉石於海砂或河砂、海砂各半的水泥砂浆，其抗压、抗弯及抗拉强度，会随著炉石添加量增加而增加，其中以40%~60%炉石替代量为最佳，但是炉石替代量过高，晚期强度会下降；在相同水灰比状况下以海砂拌和水泥砂浆做比较，以非标准砂拌和有较高的抗压强度，其强度约比标准砂高10%左右。

In the aspect of shrimp migration test, the finding reports that shrimp would use the porosity filtering to crawl towards upstream when the flow rate is at 0.001cms, and do so on the bottom of the fishway when the flow is even less.

试验结果显示，在水理试验方面，改良后鱼骨型鱼道水位皆比原鱼骨型鱼道高，流量则比原鱼骨型鱼道低，显示多孔隙滤材能有效改善流况；排砂试验方面，泥砂约於时间第30分钟即达到输砂平衡，排砂率在97％以上，残留於鱼道之泥砂为3％以下，证明增设多孔隙滤材并不影响其排砂率；鱼类上溯试验方面，粗首鱲於试验时间内，上溯率达73％以上，皆比原鱼骨型鱼道为高，显示改良后鱼骨型鱼道更适於鱼类上溯；而溪虾上溯试验方面，发现溪虾於流量0.001时，藉由多孔隙滤材向鱼道上游攀爬，再由量更小的情况下，溪虾便由鱼道渠底向上游攀爬。

By studying reservoir rock characteristics, diagenesis and physical property, investigation showed that there were distributary channel, branch channel, mouth bar, distal bar, sand sheet, lakeshore, shallow lake and limestone flat . we concluded that the reservoir of N1～N21 is low porosity and permeability reservoir with the types of primary porosity and secondary intergranular porosity, which is in the early diagenetic stage B into the late diagenetic stage A subperiod. The role of effecting reservoir physical property is deposition, cementation, dissolution and tectonic rupture. After researching of reservoir, we divided it into three categories and division the favorable facies belt and relatively favorable. We think that the favorable facies belt is braided river delta front and partly shallow lake in east of the Fault Ⅶ. favorable reservoir is in the first and the second class.

It can be seen from the results that: water potential in quartz sand layer decreases with increasing thickness of the quartz sand layer under fixed sprinkling rate and increases with increasing sprinkling rate under fixed thickness of quartz sand layer; some of water above quartz sand layer flows down through the quartz sand layer and some flows down along edges of the quartz sand layer; some of water detoured the quartz sand layer flows into the region below the quartz sand layer closely along lower surface of the quartz sand layer.

实验结果表明：在喷水强度一定情况下，石英砂层中的水势随石英砂层厚度的增加而减小；在石英砂层厚度一定情况下，石英砂层中的水势随喷水强度的增加而增大；石英砂层上方的水部分通过石英砂层向下流动，部分绕过石英砂层向下流动；绕过石英砂层的水部分地紧贴石英砂层下表面向石英砂层下方的黄土中流动。

Using maximum flooding surface and local explosure erosion surface as the correlation framework surface in the 4-th hierarchical base-level cycles, sand-body in the 3-th hierarchical base-level cycles formed in the 4-th hierarchical base-level cycles may be correlated layer by layer. The law of the sand-body and the characters of reservoir heterogeneity formed in the 4-th hierarchical base-level cycles are discussed. The study shows:①During early period of the 4-th hierarchical base-level cycle rising, subaqueous distributary channel formed, continuously stacked vertically, and migrated in limit range laterally, and channel sand-body stretches farther longitudinally, and lacks interbeds of mud rock and siltsand in sand rock, reservoir heterogeneity is relatively weak.②During mid-period of the 4-th hierarchical base-level cycle rising, subsaqueous distributary channel migrated actively, channel divided and converged strongly to form netted sand-body and sand sheet mainly, but interbeds of mud rock and siltsand increases gradually in sand-body, reservoir heterogeneity increased.③During later period of the 4-th hierarchical base-level rising and early period of the 4-th hierarchical base-level falling, reservoir sand-body was poor, and only form thin sand-body of subsaqueous distributary channel, subsaqeuous creveas and distal mouth bar, sand-bodys are surrounded by mud and silt rock.

进一步采用以第4层次基准面旋回中相当最大湖泛面的相转换面和具有区域性暴露侵蚀作用的层序边界面为等时地层对比框架的边界，对发育于MSC2—MSC4三个第4层次基准面旋回的第3层次基准面旋回内砂体进行了逐层等时对比，探讨第4层次等时地层对比格架内储集砂体发育分布规律，及储集砂体的非均质性特点，研究发现：①第4层次基准面上升初期发育的水下分流河道，砂体呈连续叠置、侧向迁移受限，纵向上呈长距离延伸的带状产出，砂体间泥、粉砂岩夹层少，储层非均质性相对较弱；②在第4层次基准面上升中期发育的水下分流河道侧向迁移活跃，纵向延伸过程中分流汇合作用强烈，以形成网状或席状连片砂体为主，但砂体间泥、粉砂岩夹层逐渐增多，储层非均质性增强；③第4层次基准面上升晚期和下降早期，不利于储集砂体发育，仅出现少量薄的水下分流河道、水下决口扇、远—河口砂坝砂体。

There are generally 3 types of sand production: the output of inorganic profile control agent in Mongolia Oilfield (grain size between 0.05 and 3 mm); the output of cement paste with formation debris (grain size between 0.03 and 8mm) in Xilin Oilfield caused by casing failure; and the output of loose sand grains in Hanan Oilfield and Anan Oilfield.

这些出砂没有形成规模，只出现在个别的井组和单井。因此本着少投入，多产出的原则，对国内的机械防砂和化学防砂技术进行了对比，取其长处，形成了适合二连油田的筛管悬挂式防砂工艺、简易防砂管柱技术和防砂泵防砂3项技术。

Based on the measure of sand geometry in M Block and comparison of results calculated with Spherical, Exponential and Gaussian Model, it is concluded that different variogram models get very different variogram range in major and minor direction.
