准噶尔盆地二叠系芦草沟组致密油储层主要为白云岩与碎屑岩过渡的云质岩沉积，目前，主要采用直井分层压裂、水平井分段压裂等进行开发生产，也尝试过酸化/酸压改造。采用旋转岩盘试验仪系统测试了常规盐酸体系、胶凝酸体系和转向酸体系与吉251井岩心的反应速度常数、频率因子、活化能、反应级数和 H +有效传质系数等反应动力学参数，建立了反应动力学方程，可为酸压优化设计提供可靠的依据。与典型石灰岩、白云岩、复杂岩性油气藏的反应动力学方程对比表明，该储层的酸岩反应为传质-表面反应共同控制。

Target formation of Permian Lucaogou tight oil reservoirs in Junggar Basin is the transi-tion deposition of dolomite and clasolite.Tight oil is commonly developed with layered or staged hy-draulic fracturing,as well as acidizing or acid fracturing.This paper tested the acid-rock reaction ki-netics parameters of well J25 1 core samples with conventional hydrochloric,gelled acid and self-di-verting acid by rotating disk apparatus.These parameters include reaction rate constant,frequency factor,reaction activation energy,reaction order and effective H + mass transfer coefficient.Reaction kinetic equation has been established,which can provide reliable basis for acid fracturing optimization design.Compared with that for limestone,dolomite,and complex lithology,the acid-rock reaction of this transition deposition was controlled by mass transfer and surface reaction.
