| 摘 要： | 利用美国Micromeritcs ASAP2000自动等温吸附仪,测试了鄂尔多斯盆地煤储层孔隙特征。在测试数据分析的基础上,确定了等温吸附和脱附曲线3种类型：第1类属孔结构是具有平行板构成的狭缝毛细孔型;第2类为发育一端尖灭的不平行的裂隙型;第3类属“墨水瓶”型孔。总结了鄂尔多斯盆地煤储层几种常见的比表面积分布曲线及累计孔体积分布曲线模型。

| Abstract: | Porous characters of coal reservoirs in the Ordos Basin tested using the Micrometrics ASAP 2000 automatism isothermal adsorption instrument made in America. Based on analyzing the test data,three variety types of isothermal adsorption and desorption curves are confirmed. The first type is that the hole structure is provided with slit capillary bore; the second is usually the type of upgrowthing one end nipped unparallel crevice ; the third belongs to the pores shaped "inkpot". Some kind of usual specific surface distribution curve and accumulative total porous volume distribution curve model of coal reservoirs in the basin are summarized in this paper. |
