Description

Изобретение относитс  к нефтега- зодобьгаающей промьшшенности, в частности к пенообразующим составам, и может быть использовано дл  глушени  скважин с низким пластовым давлени- ем, а также дл  ограничени  водопри- токов в скважину.The invention relates to the oil and gas shedding industry, in particular to foaming compositions, and can be used to kill wells with low formation pressure, as well as to limit water inflow into the well.

Цель изобретени  - повьппение устойчивости пены и сохранение за счет зтого фильтрационных свойств продуктивного элемента.The purpose of the invention is to increase the stability of the foam and preserve the filtration properties of the productive element.

Пенообразующий состав готов т следующим образом.The foam formulation is prepared as follows.

92 292 2

Предварительно готов т растворы полиакриламида и бентонита на пресной воде и оставл ют на сутки дл  набухани . В приготовленный раствор бентонита добавл ют пенообразователь сульфонол или ОП-10, затем.КССБ-4 и раствор тщательно перемешивают, Затем в этот раствор ввод т приготовленный раствор ПАА, и раствор перемешивают до однородного состава.Solutions of polyacrylamide and bentonite in fresh water are preformed and left to swell for a day. To the prepared solution of bentonite, a sulfonol or OP-10 foaming agent is added, then. KBSB-4 and the solution are thoroughly mixed. Then, the prepared solution of PAA is introduced into this solution, and the solution is mixed until a homogeneous composition.

В таблице приведены результаты испытани  данного пенообразующего состава в сравнении с составом по прототипу, свидетельствующие о повышении устойчивости пены.The table shows the results of testing this foaming composition in comparison with the composition of the prototype, indicating an increase in foam stability.
