Изобретение относитс к геофизическим способам оценки качества ценентированш затрубиого иространства.The invention relates to geophysical methods for assessing the quality of the centered space.
В практике бурени глубоких скважин ujHpoKo и эффективно примен ютс геофизические методы оценки технического состо ни скважин: скважинна радиометри , термо 5етри и акустика. Использу комплекс указанных методов, оценивают высоту нодъема иемеита , его распределение в затрубиом пристраистве , степень сцеплени цементного кольца с колонной и породой.In the practice of drilling deep wells, ujHpoKo and geophysical methods for assessing the technical state of wells are effectively used: well radiometry, thermal methods and acoustics. Using the complex of these methods, estimate the height of the ymeite aggregate, its distribution in the cement habitat, the degree of adhesion of the cement ring with the column and rock.
Недостатком известного способа контрол механической св зи цемента с обсадной колокной вл етс невозможность отличить случаи сущсствова и в цементном камне микроканалов от случа слабого контакта колонны с цементным камнем (при проведении акустической цементометрин ч обоих случа х образуетс трубна волна). Вместе с тем технологи освоени/т скважии в этих случа х должна быть различной.The disadvantage of the known method of controlling the mechanical connection of cement with a casing bell is the inability to distinguish cases in the cement stone of microchannels from the case of weak contact of the column with cement stone (when conducting acoustic cementometer in both cases a tube wave is formed). At the same time, the technology of development / ton of the well in these cases should be different.
Целью изобретени вл етс повышение эффективности контрол . Сущность изобретезн1Я состоит в том, что измен ют диаметр ко .тонны путем изменени давлени ил темп ратуры внутри ее и oдиoвpe.eннo провод т геофизические измерени .The aim of the invention is to increase the efficiency of the control. The essence of the invention is that the diameter of the cubic ton is changed by changing the pressure or the temperature inside it and the gyophysical measurements are carried out.
Известно, что если внутрл обсадной колонны );зменить давление или температуру, It is known that if the inner casing); change the pressure or temperature,
то под действием расн}фаюш,их диаметр ее увеличиваетс , и зазор между колонной и цементным кольцом уменьшитс . Пр) проеедеини акустической цемеитометрии в случае слабого контакта величина амнллтуды сиадст до О, а при наличии каналов спад амплитуды ограничитс определенным уровнем, ве ..;ичипа которого может характеризовать 5сличину канала.then, under the action of rasn} fayush, their diameter increases, and the gap between the column and the cement ring decreases. Ex) in the case of weak contact, the amount of amnlltuda siadst to O, and in the presence of channels, the amplitude decay will be limited to a certain level, the height of which can characterize the channel.
Предлагаемый способ ко1Г1рол включает в себ следующие операции: геофизические измерени в скважине, например акустические у-спектроскопические, либо гамма-гамма-измереии , воздействие иа ствол обсадной колонны, повторные геофизическ1 е измерени выбранным методом в процессе воздействи . Воздействие на ствол колоины осуществл етс путем повышени давлени или измемеипп температуры ее.The proposed method includes the following operations: geophysical measurements in the well, such as acoustic y-spectroscopic or gamma-gamma measurements, impact from the casing shaft, repeated geophysical measurements by the selected method during the treatment. The impact on the coloin trunk is carried out by increasing the pressure or measuring its temperature.
