Abstract
The authors discussed different types of high energy gas fracturing techology, designed a crack combusting caseless high energy gas fracturing device and put it into effect. The fracturing depth varies from 1000 to 5000m. In 5ms the pressure comes to maximum. The working time can be adjusted from 700 ∼ 2000ms. So multi-crack fracturing and long time crack-extending can be acquired. This technology is very simple and reliable, and production increasing is very remarkable. It will be applied expansively.
