摘要/Abstract

摘要：

为明确新疆玛湖砂砾岩油藏储层条件下,超临界CO₂浸泡对玛湖不同黏土矿物含量砂砾岩储层物性的影响规律。首先,根据现场储层岩心全岩X射线衍射（XRD）结果确定了储层黏土矿物类型及占比：高岭石（1.52 %）、蒙脱石（0.42 %）、绿泥石（0.73 %）、伊利石（0.68 %）;其次,制作了与储层岩心孔渗接近的人造岩心;最后,利用超临界CO₂高温高压反应装置在储层温度70 ℃、压力20 MPa条件下,开展超临界CO₂浸泡对玛湖不同黏土矿物含量砂砾岩储层渗透率影响的实验研究。结果表明：黏土矿物含量为2.5 %~6.0 %时,注入CO₂后储层渗透率增加,黏土矿物含量越低,作用时间越短,渗透率增加越明显;当储层中黏土矿物含量大于7.5 %时,随着作用时间的增加,渗透率逐渐降低,且黏土矿物含量越高降幅越大;黏土矿物含量为6.0 %~7.0 %时,CO₂对储层渗透率改善效果最好。

Abstract:

In order to clarify the influence of supercritical CO₂ immersion on the physical properties of glutenite reservoirs with different clay mineral content in Mahu under the conditions of Xinjiang Mahu glutenite reservoir. Several researches have been done. Firstly, the type and proportion of clay minerals in the reservoir were determined according to the results of X-ray diffraction （XRD）：kaolinite （1.52 %）, montmorillonite （0.42 %）, chlorite （0.73 %）, illite （0.68 %）. Secondly, the core which is close to the pore permeability of reservoir core is made manually. Finally, under the condition of reservoir temperature at 70 ℃ and pressure of 20 MPa, using supercritical CO₂ high-temperature and high-pressure reaction device, and the experimental study on the influence of supercritical CO₂ immersion on the permeability of sandy conglomerate reservoir with different clay mineral content was carried out. The results show that when the clay mineral content is 2.5 % ~ 6.0 %, the permeability of the reservoir increases after the injection CO₂, the lower the clay mineral content, the shorter the action time and the more obvious the permeability increase. When the clay mineral content in the reservoir is greater than 7.5 %, with the increase of the action time, the permeability gradually decreases, and the higher the clay mineral content is, the greater the decrease is. When the clay mineral content is 6.0 % ~ 7.0 %, CO₂ has the best effect on improving reservoir permeability.

Key words: supercritical CO₂, immersion, clay mineral content, interaction, permeability, sandy conglomerate reservoir
