摘　　要：在大量统计分析及室内试验基础上,对中原油田储层特征及储层损害因素进行了细致的分析研究,总结出中原油田中后期开发中引起储层损害的主要因素为:①外来流体不配伍;②完井及修井;③细菌及其代谢产物;④固相颗粒;⑤增产措施带来二次污染。提出了相应酸化解堵技术处理对策为:①砂岩缓速酸增注;②常规土酸酸化;③氧化深穿透复合解堵;④无钙沉淀缓速酸降压增注;⑤缩膨增注。以文南油田为例对矿场应用情况进行了统计分析。On the basis of a lot of statistical analyses and laboratory experiments, the reservoir characteristics and factors of formation damage were analyzed and studied in Zhongyuan Oilfield, the major factors of formation damage were summarized at the mid-late stage of development. Related countermeasures for technical treatment are put forward and field application is statistically analyzed by using Wennan Oilfield for example.
