- 摘要：
- <p>A method of grouting porous gas - and petroleum - bearing formations with a cementitious material (40) comprising ultrafine ground slag is useful for primary and remedial cementing of a wellbore (37). A composition is provided which comprises water, a dispersant, slag and an accelerator to activate the slag. <IMAGE></p>
