塔里木盆地吉拉克地区三叠系储层岩石学与地层损害分析

PZTROLOGY AND FORMATION DAMAGE OF TRIASSIC RESERVOIR IN JILAKE AREA,TALIMU BASIN

本文在分析塔里木盆地吉拉吉地区三叠系储层岩石学特征的基础上，探讨了潜在的地层损害因素。文章指出，塔里木盆地吉拉吉地区三叠系地层损害以水敏和碱敏为主，速敏和酸敏次之，还存在出砂的危险，且不宜采用酸化增产措施。

On the basis of analyzing the petrologic characteristics of Triassic reservoir in jilake area,Talim u basin,the potential factors of formation damage are discussed.It is proposed that wa-ter sensitive and alkalinity sensitive are main factors of formation damage,acidizing is not suitable for the reservoir,meanwhile,there are the possibility of velocity sensitivity and sand inflow in there ervoir.
