摘要
采用前置酸多层酸化工艺进行油层改造,一次性下入管柱酸化堵塞层,同时压裂未开发层,即对堵塞油层段进行解堵,又对新开采层段进行压裂改造开发。以涧峪岔油田为例,同区块开发长6油层,酸化已开发长611及未开发长613,并进行长613油层压裂合采,比单纯采取二压工艺合采有效的提高了油井产量。
Using pre-acidification process for multilayer reservoir acid transformation,one layer down into the column acidification blockage, while fracturing undeveloped layer, ie plugging oil segment,but also on new mining layer fracturing segment development.In Jianyucha oilfield,for example, with the development of Chang6 reservoir, acidification has been developed and undeveloped Chang 611 and Chang 613,and Chang 613 layer is fractured. Compaction process is more effective than simply taking two commingled,and improve the well production.
