There is larger difference of the vertical permeability in block Dul6 of Dujiatai reservoir,the reservoir development is not obvious at all layers,so a new type of temporary plugging agent has been developed,the temporary plugging agent can be used in temporary plugging of high permeability formation and plug removal by itself in the production process.Through combination of plugging and plug removal,temporary plugging of high permeability formation can be realized; reconstruction of low permeability reservoirs can be once completed.Field tests show that the temporary plugging agent has good application effect and broad promotion prospect.%针对杜16块杜家台油层纵向渗透率差异较大,部分井各层发育不明显,不具备工具卡封条件的具体状况,研制了新型的暂堵剂,对高渗透层具有暂时封堵,又能在生产过程中自己解除.通过暂堵与解堵相结合,实现对高渗层的暂时封堵,对低渗透层的油层改造一次完成.现场试验见到良好的措施效果,具有广阔的推广前景.
