摘要
针对伊拉克X油田开发过程中面临的开采难度大等问题,室内通过旋转岩盘实验仪,分别测定了盐酸与伊拉克X油田碳酸盐岩储层岩心在90℃、120℃和140℃下反应的速度常数、反应级数以及H+有效传质系数等,通过以上酸岩反应动力学参数,建立了不同温度下酸岩反应动力学方程,同时确定了盐酸与该储层岩心反应的反应活化能,为该油田碳酸盐岩储层酸压优化设计提供可靠依据。
In view of the difficulty of mining in the development of Iraqi X oilfield, the core of carbonate and rock reservoirs of hydrochloric acid and Iraqi X oilfield were measured at 90 ℃, 120 ℃ and 140 ℃ by rotating rock disk experimental instrument. The reaction rate constant, the number of reaction stages and the H+ effective mass transfer coefficient, etc, through the above kinetic parameters of acid rock reaction, the kinetic equation of acid rock reaction at different temperatures was established, and the reaction of hydrochloric acid with the core reaction of the reservoir was also determined. The activation energy provides a reliable basis for the acid pressure optimization design of the carbonate reservoir in the oilfield.
