The water cut of production of L-Reservoir in Laojunmiao Oilfield has reached 88.9%.The cumulative recovery as predicted by production curve will be 48% at a water cut of 98%.However,a cumulative recovery of 57% is predicted by using core analysis togather with well testing data from some inspection wells.The difference between these two figures is attributed to the effect of sweeping efficien- cy of the injected water.Inportant factors affecting sueh an efficiency are, injection patterns,degree of sweep,heterogeneities in the pore texture and the reservoir rock complexes.In order to enhance the recovery,following measures are suggested. 1.A separate well pattern will be adopted for the development and the exploitation of the more permeable L_3 zone.Changing the direction of flow of the injected water and increasing the rate of withdrawal...etc.should be taken to increase the degree of displacement efficiency. 2.For the less permeable L_1 and L_2 reservoirs,infilling drilling with a more dense pattern,increasing the number of injection wells,improving the in- jection profile,and increasing the amount of water injection...etc.should be applied to increasing the volumetric sweep afficiency.

老君庙油田 L 油层综合含水已高达88.9%,预计含水98%时采收率可达到48%。利用岩心驱油效率与试油时的含水率作出的关系曲线进行测算,当含水98%时,水驱油效率可达57%以上。二者的差距主要原因是注入水波及体积造成,其影响因素主要是注水方式、水洗程度、油层平面和剖面上渗透车的组合及油层孔隙结构的不均匀性。为了提高 L 油层采收率,对高渗透层 L_3,拟通过单独井网开采、改变液流方向、加大排液量等手段提高水洗程度;对中低渗透层 L_(1、2),拟通过加密井网、增加注水井点、改善剖面吸水状况、提高注水量等办法扩大水驱体积。

This paper covers three parts.1. A study is made on the reliability and applicability of existing simplified methods available for computing elastoplastic story drift responses of multistory structures subjected to earthquake motions.2.Based on a large number of calculated results of elastopiastic story drift, it concludes that among the three factors, mass, rigidity and yield shear strength, the yield shear strength and its distribution along the height of structure is the principal factor affecting the value of story drift.3.A simplified formula for the maximum elastoplastic drift response of a multistory uniform shear type structure subjected to earthquakes is presented.The possible concentration of plastic deformation at weaker stories of a non-uniform structure and the so called "standard allocation of yield shear strength" to uniformize the story drifts along the height of structure are discussed.

本文首先对国外现有几种结构弹塑性地震位移反应简化计算方法进行了比较与评述。然后通过算例分析,指出在多层剪切型结构的质量、刚度和屈服抗剪强度三个因素中,屈服强度及其沿高的分布是影响结构弹塑性层间位移的关键因素。在此基础上,通过统计分析,提出了多层均匀结构弹塑性最大层间位移与相应的弹性层间位移之间关系的简化公式。最后对结构的不均匀性可能造成的层间塑性变形集中及屈服强度沿高度的标准分布进行了一些讨论。

The dielectric spectra of the cubic AgBr emulsions doped with Na2S202 and Na2S have been studied. Sodium thiosulfate which is added into AgBr emulsions acts in two ways. 1, On the surface of the AgBr microcrystal, the adsorption of sodium thiosulfate is the primary factor when its concentration is lower than 1×10-4mol/mol AgBr. In this range, the ionic conductivity of AgBr microcrystal decreases slightly with increasing concentration. The fmax of the dielectric loss curve are shifted slightly to lower frequencies, and Δ(logfmax) depend upon the condition of the AgBr microcrystal surface. 2, When the concentration of Na2S2O3 is higher than 1×10-4mol/mol AgBr, it is getting predominant that the surface of the AgBr microcrystal is corroded by S2O3= ions. As a result of corrosion, the surface of the AgBr microcrystal becomes more heterogeneous and the distribution of the relaxation time τ of the interface polarization is broadened relatively. On the other hand, when pAg of the emulsions are increased, fmax of the samples are shifted to higher frequencies.fmax of the samples with Na2S (<1×10-8 mol/mol AgBr) are shifted slightly to lower frequencies. When the dried samples are heated at 75℃ and 110℃ for 6h respectively, S= ions diffuse slowly into the crystal lattice of AgBr, the ionic conductivity of the AgBr microcrystal increases, fmax of the samples are shifted to higher frequencies.

本文研究了用1×10~(-5)mol~1×10~(-2)mol Na_2S_2O_3/mol AgBr和1×10~(-4)mol~1×10~(-2)mol Na_2S/mol AgBr掺杂的立方AgBr乳剂的介电吸收频谱。发现在我们的实验条件下,当Na_2S_2O_3的加入量小于1×10~(-4)mol/mol AgBr时,Na_2S_2O_3,在AgBr微晶上吸附的影响占主要,样品介电吸收峰的f_(max)稍向低频方向位移,f_(max)位移量(△log f_(max))的大小与AgBr微晶的表面状况有关。当Na_2S_2O_3的加入量大于1×10~(-4)mol/mol AgBr时,Na_2S_2O_3对AgBr微晶表面的溶蚀的影响逐渐占优势,使AgBr微晶表面的结构不均匀性增加,同时乳剂的pAg上升,结果样品的f_(max)逐渐向高频方向移动,介电吸收峰亦相应展宽。Na_2S的加入量小于1×10~(-3)mol/mol AgBr时,样品的f_(max)有稍向低频位移的趋势。当将掺Na_2S的样品干燥后在75℃和110℃下放置6小时后,f_(max)明显向高频方向移动。
