摘　　要：以胜坨油田坨 74断块储层敏感性评价为基础 ,对该断块钻井和射孔作业中的主要损害因素制定出具体可行的油层保护措施。措施实施后油井初产平均提高 83.4%,且产量递减率大大降低。现场应用效果表明 ,采用的油层保护措施得当 ,对解放油层生产力、提高单井产量和提高最终采收率等具有重要作用。Specific and feasible reservoir protection measures are taken aiming at major damage factors in drilling and perforation job of Tuo 74 fault block in Shengtuo oilfield based on the reservoir sensitivity evaluation of the block. After implementation, initial production of oil wells has risen 83.4% on the average, and production decline rate is reduced greatly. The field application effectiveness shows that the suitable reservoir protection measures play important role in liberating reservoir productivity, increasing singlewell production, enhancing ultimate recovery factor and so on.
