a r t i c l e i n f o In many mining, civil, and petroleum engineering applications diamond bit drilling is widely used due to high penetration rate, core recovery and its ability to drill with less deviation. Recently, many research have been conducted to estimate the penetration rate of diamond drilling which can be considered as one of the most important parameters in project planning and co...

Oil and gas energy is one of the necessary sources for social development. In process oil development exploration, hydraulic fracturing technology plays a vital role. Hydraulic can not only stabilize production conventional fields, realize low-permeability reservoirs, help adjustment old but also increase special reservoirs tap potential fields. this paper, an electrical simulation experiment m...
