Abstract

Получен каротажный прибор (9) с поперечной индукцией, имеющий передатчик (18) и приемник (19) для выборочного исследования характеристик пласта, причем прибор имеет симметричную экранированную подразделенную катушку (30, 32) передатчика и противодействующую катушку (33), расположенную между подразделенными катушками (30, 32) передатчика, для уменьшения возбуждения в приемнике (19) изменяющегося во времени магнитного поля передатчика. Прибор обеспечивает симметричное экранирование катушек и заземление либо только на конце передатчика, либо на конце приемника для уменьшения внесения индуцированных токов в принятый сигнал. В приборе применен изолятор между электроникой приемника и проводящим корпусом приемника, входящим в контакт с проводящей скважинной жидкостью для уменьшения паразитного тока, протекающего в контуре, формируемом верхним корпусом, подводящей сквозной трубой, нижним корпусом и скважинной жидкостью, примыкающей к корпусу зонда или барабану. Применена внутренняя контрольная петля для отслеживания изменений тока передатчика по вещественной и квадратурной составляющим принятого сигнала данных. Гальванический электрод (120) расположен в одном барабане с индукционным каротажным приемником (19) и передатчиком (18).Международная заявка была опубликована вместе с отчетом о международном поиске.
