Description

Известные способы замедлени  сроков схватывани  цемента отличаютс  известной сложностью.Known methods for delaying the setting time of cement are known complexity.

Предлагаемый способ не имеет этого недостатка, так как цемент затвор етс  растворенным в воде трплоном Б от 0,1 до 0,5% веса цемента .The proposed method does not have this disadvantage, since the cement is shuttered by Bpllon B dissolved in water from 0.1 to 0.5% by weight of cement.

При тампонажах скважин зачастую требуетс  замедлить сроки начала схватывани  цементов. Особенно важно замедление сроков схваЛывани  тампонажиых цементов при заливке колонн, спускаемых на большие глубины, где высокие забойные температуры и давлени  значительно ускор ют процесс отверждени  цементного камн .With cement wells, it is often necessary to slow down the time it takes for the cement to start setting. It is especially important to slow down the setting times of cement cements when pouring columns, which are lowered to great depths, where high downhole temperatures and pressures significantly speed up the process of cement stone curing.

Добавки растворенного в воде трилона Б от 0,2 до 3% веса цемента позвол ют замедлить сроки начала схватывани  с 3,5 до 14 час. без снил ени  прочности цементного камн .Addition of trylon B dissolved in water from 0.2 to 3% by weight of cement slows down the time it takes to start setting from 3.5 to 14 hours. without reducing the strength of cement stone.

Предмет изобретени Subject invention

Способ замедлени  сроков схватывани  цементов, примен емых при тампонажах скважин, заливке колонн, спускаемых на большие глубины, отличающийс  тем, что, с целью регулировани  сроков схватывани , цемент затвор етс  растворенным в воде трилоиом Б (двузамещеина  натриева  соль этилен, диамиио-тетрауксусной кислоты) от 0,1 до 0,5% веса цемента.A method for slowing down the setting time of cements used in well tamponing, pouring columns that are lowered to great depths, characterized in that, in order to regulate the setting time, the cement is closed with trilioma B dissolved in water (disubstituted sodium salt ethylene, diamio-tetraacetic acid) from 0.1 to 0.5% by weight of cement.
