摘　　要：根据XJ23-1油田韩江组岩性、物性资料等的综合分析,对XJ23-1油田韩江组储层主要损害因素进行了初步的评价和诊断,并按照标准SY/T 5358—2002《储层敏感性流动实验评价方法》中所述方法评价了XJ23-1油田韩江组岩心的速度敏感性、水敏性、酸敏性、碱敏性和应力敏感性。研究结果表明,该储层段表现为非流速敏感性、中等偏强的水敏性、中等偏弱的盐酸敏感性、中等偏强的土酸敏感性、较弱碱敏感性、较弱的应力敏感性。Based on the data of comprehensive analysis of lithology and physical property in Hanjiang Formation of Xijiang 23-1Oilfield,the main reservoir damage factors in Hanjiang Formation are evaluated and identified.Then,the velocity sensitivity,water sensitivity,acid sensitivity,alkali sensitivity and stress sensitivity of the cores from Hanjiang Formation are evaluated according to SY/T5358-2002《Formation Damage Evaluation by Flow Test》.The results of the study indicate that the reservoir is non-velocity sensitivity,moderate to strong water sensitivity,medium-weak hydrochloric acid sensitivity,moderate-strong soil acid sensitivity,weak alkali sensitivity and the weaker stress sensitivity.
