Abstract

Настоящее изобретение относится к способу удаления HS из бурильного глинистого раствора, где к бурильному глинистому раствору в глинистую систему добавляют относительно слабо растворимую соль двухвалентного железа, после чего бурильный глинистый раствор циркулирует в системе, в то время как сероводород в бурильном глинистом растворе реагирует с относительно слабо растворимой солью железа, превращаясь в сульфид железа. Кроме того, изобретение включает применение относительно слабо растворимой соли двухвалентного железа, предпочтительно оксалата железа (II), для удаления HS из бурильного глинистого раствора. Целью настоящего изобретения является использование экологически безвредной соли железа с ограниченной растворимостью в щелочной среде для удаления HS из бурильного глинистого раствора.Международная заявка была опубликована вместе с отчетом о международном поиске.
