Abstract

Дюзата за пулсации е предназначена за вграждане всондажни корони, например единични или триконусни, за получаване на пулсиращ струен поток от тиксотропен сондажен флуид при сондажни операции. С нея се увеличава сондажната скорост. Дюзата има входенотвор (33), свързан с вътрешна кухина (32) и изходен отвор (31), размерите на които са избрани по такъв начин, че да се получи циклично разпространение на смущенията в разделящата граница между флуида, течащ направо през дюзата, и флуида, моментно задържан в кухината. По този начин се получава поток със самовъзбуждащи се осцилации в дюзата и от нея излиза бързо пулсиращ поток.
