Abstract

Способ обработки земляного пласта, включающий введение в земляной пласт первого количества первого блокированного изоцианата в жидкой фазе; введение в земляной пласт второго количества второго блокированного изоцианата в жидкой фазе; где группа второго блокированного изоцианата имеет более низкую разблокирующую температуру, чем группа первого блокированного изоцианата; введение в земляной пласт по меньшей мере одного соединения активного водорода и контактирование первого и второго блокированных изоцианатов и соединения активного водорода для образования эластомерного геля. Комбинация двух блокированных изоцианатов дает такой взаимоусиливающий эффект, что время отверждения может быть оптимизировано непредвиденным способом, если исходить из свойств каждого блокированного изоцианата по отдельности.
