Abstract
Many acid stimulation technologies have been done to muddy limestone reservoir in Huabei oilfield, but achieved a little. Engineers and geologist made many geology data analysis and laboratory experiment, optimized a practicable acid fracturing reform technology, which use ahead fluid and high-temperature emulsified acid and solid nitric acid fracturing technology. Applications have increased production, find a new approach for muddy limestone fracturing of Huabei oilfield.
