摘要:
Methods and compositions for forming permeable cement sand screens in well bores are provided. The compositions are basically comprised of a hydraulic cement, an acid soluble particulate solid, a liquid hydrocarbon solvent soluble particulate solid, a particulate cross-linked gel containing an internal breaker which after time causes the gel to break into a liquid, water present in an amount sufficient to form a slurry, a gas present in an amount sufficient to form a foam and a mixture of foaming and foamed stabilizing surfactants.
