With the rapid development of China’s society and economy, the demand of water become more and more prominent. Particularly in recent years, in many parts of southwest, northwest and north China, severe drought occur, local people and livestock’s demand of water is extremely difficult to meet. Well drilling work is very urgent. Aim at the current situation that a part of bedrock wells yield low water , this paper carry out the research and test to raise water yield across bedrock wells fracturing, base on water wells fracturing mechanism, fracturing fluid, propping agent, and fracturing technology. One kind of hydraulic fracturing techniques which is suitable for our country situation is successfully developed, and it provides technical support for rational development and utilization of groundwater resources, also ease the tension of water shortage in many mountains.
