1) Fine-sandstone
细粒砂岩
1.
The deformation characteristics and the plastic-loop of the fine-sandstone is studied under the loading and(unloading) condition at the three different deformation-rates and the two different stress-levels,the results show: 1) There is really the plastic-loop in the deformation curve for the loading deformation curve is different form the unloading deformation curve.
通过对循环载荷条件下细粒砂岩在不同载荷水平、不同位移速率时的变形特性及其塑性滞回环演化规律的分析发现:1)循环载荷条件下岩石的加、卸载曲线不重合,将形成一封闭的塑性滞回环,该塑性滞回环从第2循环起将趋于稳定;2)不同载荷水平和不同位移速率下第1循环时的各拟合参数值与第2循环相比存在有较大变化,但从第2循环曲线起,各拟合参数均将逐渐趋于恒定;3)随着位移速率和载荷水平的变化,其拟合参数将随之而发生变化;4)在相同位移速率和相同载荷水平条件下,同一次循环时岩石变形曲线的加载段与卸载段的相应拟合参数值不同。

通过对细粒砂岩在不同位移速率、不同载荷水平时循环加、卸载条件下变形的演化规律的实验研究发现,细粒砂岩在循环加、卸载条件下的卸载曲线与加载曲线不相重合,将形成一封闭的塑性滞回环,且该塑性滞回环从第2次循环起几乎不发生变化。

Experimental Research on the Evolution of Hysteresis Curve of Fine-sandstone with Different Water Saturation;
通过周期性循环载荷作用下的烘干、自然干燥、饱水等3种不同水饱和度时细粒砂岩变形特性及其滞回曲线演化规律的实验研究,分析结果发现随着岩石含水量的不断增加,岩石的强度、变形及其弹性模量将随之减小,每次循环形成的滞回曲线的变化有越加明显的演化趋势,但是随着循环次数的增加各个应变相对残余变量均逐渐趋于稳定。

Based on the analysis and study on reservoir microcosmic composition,rock component as well as pore geometry,it is determined that the reservoir controlling factors are affected by source,depositional system,sedimentary micro-facies,sandstone particle size,compaction action and kaolinite content.
三塘湖盆地牛圈湖区块中侏罗统西山窑组(J2x)油藏储层以低孔低渗和低孔特低渗为主,通过储层微观组成、岩石组分及孔隙结构等的分析研究,确定该油藏的储层控制因素主要受物源、沉积体系和沉积微相、砂岩粒级、压实作用以及高岭石含量的影响,其中压实作用是主要的减孔因素。
