CURABLE CROSS-LINKABLE COMPOSITIONS FOR USE AS LOST CIRCULATION MATERIAL |
摘要 |
The present invention relates to compositions and methods for reducing or preventing the loss of drilling fluids and other well servicing fluids into a subterranean formation during drilling or construction of boreholes in said formation. Specifically, this invention comprises a curable cross-linkable composition capable of free radical polymerization for creating lost circulation material. The curable cross-linkable composition comprises a mixture of (i) an organic compound capable of free radical (co)polymerization comprising a moiety derived from an diisocyanate and a moiety derived from an organic polyol comprising two or more hydroxyl groups having a molecular weight of from 400 to 4,000 and (ii) a reactive diluent comprising an organic compound with a reactive group and a moiety derived from an organic polyol comprising two or more hydroxyl groups having a molecular weight of from 60 to 500.
