Abstract: Sangtanghu Niudong structure is a fractured-porousIgneous rock reservoir with low-porosity,low permeability,low pressure and low back leakage characteristics. It has achieved good effect by applying low density,high strength and leakage proof cement and fractional cementing technolo-gy. The paper carried on research in improving the cementing quality technology and cement slurry system,then gained cementing technique comprehensive supporting technologies and cement slurry system suitable to Niudong igneous rock reservoir,which was successfully applied to 2wells. cementing acceptability rate reach to 100 percent.
