摘　　要：通过对雷家区块储层岩石矿物成分分析、储层物性及敏感性分析,弄清了储层污染的主要原因及类型,同时,开展了低渗油藏解堵技术研究和应用。研究表明:采用有机缓速酸体系增加处理半径,减轻设备腐蚀;对结蜡严重,复配有机堵塞清洗剂,解除有机堵塞;在酸化工艺上,采用带泵酸化工艺,酸化后快速排酸,减少二次沉淀污染。The main reasons and types of the reservoir pollution in Leijia block were clarified through rock minerals analysis, reservoir properties and sensitivity analysis. Research and application of plugging removal technology in low permeability reservoir were carded out. The results show that organic sustained speed acid system can increase the acid processing radius and reduce the corrosion of the equipments; aiming at serious wax deposition, the compounded organic jam cleaning agent can relieve the organic jam; after the acidification, rapid flowback need be carried out for avoiding the second precipitation pollution.
