摘要

摘要: 泥页岩孔隙特征是页岩气藏储集能力及可开采性评价的关键参数。以鄂尔多斯盆地南部铜川地区瑶科一井延长组泥页岩样品为研究对象，通过扫描电镜、低温氮气吸附等实验手段，对延长组各段泥页岩孔隙特征及影响孔隙发育的控制因素进行了研究。研究表明：鄂尔多斯盆地南部延长组泥页岩孔隙类型主要有粒间孔、粒内孔、黄铁矿晶间孔、溶蚀孔、微裂缝，其中黏土矿物粒间孔最发育，有机孔基本不发育。延长组不同段的纳米孔隙发育特征有明显的差异性，长9段微孔含量相对较高，BET比表面积较大，长8段中孔比例较高，孔隙形态都以管状孔和平行壁的狭缝状孔为主；长7段有最大的宏孔比例和最小的微孔比例，比表面积最小，孔隙含有相对较多的封闭型孔，还有一端或两端开口的楔V型孔；长6段孔隙比例、比表面积大小介于其他各段之间，以平行板状的狭缝型孔隙为主。黏土矿物含量、石英含量是控制孔隙发育的主要因素，而孔隙总体积、比表面积与TOC含量基本呈负相关关系，这主要是由于孔隙中的残留烃对孔隙的堵塞作用，抽提后可以发现样品孔隙总体积、比表面积都有所增加。

Abstract: Taking the Yanchang Formation Shale for Well YK-1 in Tongchuan Area of the south of Ordos Basin as the target, pore characteristics and controlling factors were investigated by using Argon-ion Polishing Scanning Electron Microscope(SEM)and low-temperature nitrogen adsorption experiments. The results show that pores of Yanchang Formation shale can be classified into inter-granular pore, intra-granular pore, intra-crystalline pore in pyrite, dissolved pore and micro-cracks, of which inter-granular pore in clay mineral is most developed, but organic pore is basically not developed. The pore characteristics of Yanchang Formation in different members have obvious differences. Chang 9 has larger proportion of micropores along with larger specific surface area, while the pore volume of Chang 8 is occupied by largest mesopores and pore morphology of Chang 8 and Chang 9 is mainly in the shape of column and slit parallel to the wall. Chang 7 has the largest proportion of macropores, smallest proportion of micropores and corresponding smallest specific surface area, of which there are many close pores and wedge-shaped pores with one or both ends open. The proportion of pore volume and specific surface area of Chang 6 are between other members, the pore morphology of which is mainly parallel-plate shaped silt pores. The content of clay is the main controlling factor of pore development, but TOC content shows a negative correlation with the pore volume and the specific surface area, mainly due to residual hydrocarbon which block the pore space. The pore volume, the specific surface area will increase after extraction.
