| 摘 要： | 本次研究采用断面正应力大小、泥岩削刮比(SGR)、断裂带充填物泥质含量(Rm)和断面紧闭指数等定量参数,对车拐地区红车断裂封闭性进行了详细评价。结果显示泥岩削刮比(SGR)均值为0.6,断裂带充填物泥质含量(Rm)均值为0.51,泥质充填程度较高,断面正应力大小变化不大,为69.54~73.11MPa,整体较大,紧闭指数为1.28~8.25,均值为3.98。从而认为准噶尔盆地车拐地区红车断裂带二叠系及三叠系封闭性较好,侏罗系封闭性差。红车断裂带中部、北部断层封闭性较好,而发育于浅部乌尔禾组、三工河组内的小断层在现今及油气成藏期的封闭性也普遍较好。

| Abstract: | In this study,the normal stress of the cross section,mudstone smear index SGR,mud filling coefficient Rm and section closure index were used to evaluate the fracture integrity of the red car fracture in Cheguai area.The results showed that mud scraping than the SGR average of 0.6,fracture filling mud content Rm value was 0.51,the mud filling degree of section normal stress changes little,at around 69.54-73.11 MPa,the overall large,closed index was between 1.28-8.25,the average is 3.98.It is considered that the Permian and Triassic sealing of the Hongche fault in Cheguai area, northwestern margin of Junggar basin is better,and the sealing property of the Jurassic is poor.Hongche fault zone of cen- tral and Northern fault sealing is good,small faults and developed in the shallow Wuerhe group and three jurassic san- gonghe in now and in the oil and gas reservoir into a closed period is generally better. |
