本文通过薄片鉴定、X-衍射、岩石压汞及物性分析,对昆北地区切十六井区E1+2储层地质特征进行了分析。分析认为昆北地区切十六井区E1+2储层物性为中低孔隙度和中低渗透率储集空间,岩石颗粒相对较粗、分选差,胶结作用不强,泥质杂基和压实作用使该区储层物性变差的重要因素。由于压实、胶结等成岩作用使得岩石孔隙较不发育,微孔隙较多,面孔率低。喉道和孔隙非常微小,孔喉连通性较差。
In this paper, the geological characteristics of E1 + 2 reservoirs in the Shiguji well area in north Kunlun area were analyzed by thin-slice identification, X-ray diffraction, mercury intrusion and physical property analysis. The analysis shows that the reservoir properties of E1 + 2 reservoirs in Qinshui 16 well area in Kunming area are reservoir space of low porosity and medium permeability, rock particles are relatively coarse, poorly sorted, cementation is not strong, Compaction effect of the reservoir physical properties of the important factors. Due to compaction, cementation and other diagenesis, rock porosity is less developed, more microporosity, low porosity. Throat and pores are very small, pore and throat connectivity is poor.
