CLAY-SWELLING INHIBITOR, COMPOSITIONS COMPRISING SAID INHIBITOR AND PROCESSES USING SAID INHIBITOR |
摘要 |
<p>The use of an additive as a clay-swelling inhibitor, especially in the field of drilling is described. More specifically, the use of 2-methylpentane-1,5-diamine or an organic or inorganic salt of 2-methylpentane-1,5-diamine as an inhibitor of the swelling of clays in an aqueous medium is described. Also described is a drilling fluid composition or hydraulic fracturing fluid composition including 2-methylpentane-1,5-diamine or an organic or inorganic salt thereof and drilling or hydraulic fracturing processes using the compositions.</p> |
