摘　　要：针对欢喜岭油藏开发中注蒸汽压力较高的实际情况,利用高压高温注蒸汽试验,研究欢喜岭油藏注蒸汽开发与黏土矿物的相互作用影响,确定合理的附加压力损失来满足数模研究精度。300℃的蒸汽对储层黏土矿物的影响作用明显,高岭石相对含量明显降低,而蒙托石相对含量则显著增加,伊利石与绿泥石相对含量较为稳定,石英、钾长石产生部分溶蚀现象。绿泥石与储层物性相关性受绿泥石赋存状态的变化影响。经试算确定油藏数值模拟增加蒸汽吞吐井的附加压力损失系数,针对欢喜岭油藏建立油藏数值模型,解决了注汽压力上下波动符合率不高的问题。Reasearch has been carried out on interreaction influence between steam injection development and clay mineral in Hanxiling oilfield and feasible additional pressure loss to meet accuracy of numerical reservoir simulation through hi-pressure-temperature steam injection experiments, aimed at high steam injection pressure in Hanxiling oilfield, steam injection at 300 ℃ affects clay mineral immensely, kaolinite decreases and montmorillonite increases at a large degree, goeschwitzite and chlorite keeps stable, quartz and potassic feldspar changes by corrosion. Correlation between chlorite and physical property is affected by occurrence condition of chlorite, in view of Hanxiling oilfield, additional pressure loss has been confirmed by numerical reservoir simulation, the problem of low coincidence rateabout fluctuating steam injection pressure has been resolved.
