新场须二气藏储层的沉积层理缝能提高储层渗透性,较高结构成熟度及刚性颗粒(石英、长石)有利于储集性能的提高;成岩因素表明压实、压溶作用使储层进一步致密化;含量不高的自生矿物中缺乏绿泥石、高岭石,而碳酸盐矿物、自生石英矿物却分布普遍;溶解作用为建设性成岩作用,长石、石英是重要的被溶解组分;裂缝对储层孔隙度贡献极小,但对储层渗透性的改善作用十分明显;超压及烃饱和度对储层的储集性能有一定影响。
新場鬚二氣藏儲層的沉積層理縫能提高儲層滲透性,較高結構成熟度及剛性顆粒(石英、長石)有利于儲集性能的提高;成巖因素錶明壓實、壓溶作用使儲層進一步緻密化;含量不高的自生礦物中缺乏綠泥石、高嶺石,而碳痠鹽礦物、自生石英礦物卻分佈普遍;溶解作用為建設性成巖作用,長石、石英是重要的被溶解組分;裂縫對儲層孔隙度貢獻極小,但對儲層滲透性的改善作用十分明顯;超壓及烴飽和度對儲層的儲集性能有一定影響。

Daniel sedimentary fracture of the Xujiahe Formation in Xinchang increase permeability,higher structure maturity and rigid particles(quartz,feldspar) to improve reservoir property;Diagenetic factors suggest that compaction,pressure dissolving effect densification further reservoir;Chlorite and kaolinite of low authigenic mineral which have positive influences,the carbonate mineral and spontaneous quartz mineral have the negative impact are common;Dissolve is important constructive role,diagenesis feldspar,quartz is the most important being dissolved components;Fracture have low influences on reservoir porosity,but improving reservoir permeability obviously;Overpressure and hydrocarbon saturation have the positive significance for reservoir property.
