Well cementing process |
摘要 |
Improved bonding in a well system between cement, well tubular members and the formation about the well/bore at a pay zone. Drilling fluid materials (mud, solids, filter cake, etc.) are displaced at turbulent flow conditions by a slug of concentrate consisting essentially of a water-free mixture of surfactant and alcohol. The aqueous fluid cement immediately follows the slug. Residual filter cake and tubular member are water-wetted. The cement on hardening has an improved bonding to both tubular members and formation at the pay zone.
