Lithological composition and reservoir properties of Lower Ordovician Majiagou formation in the gas field Tabamiao (Ordos Basin, China)

Moscow University Bulletin. Series 4. Geology, 2016
Ordos Basin is concentrated rich areas of coal, natural gas and oil. In last years it is becoming an important mineral resource and energy base of China. To the most well-known and good studied gas fields belong Sulige and Tabamiao, where natural gas takes place in carbonate rocks of Early Ordovician time. As the result of an investigation that made by

Study on Prevention and Control of Confined Water Hazard in Deep Resource Exploitation: Scientific Basis of “GCD‐D” Design

Geofluids, Volume 2023, Issue 1, 2023., 2023
Deep mining of resources has destroyed the stress balance of original rock, formed water gushing channel, and caused the outburst of confined water, thus causing disaster. At present, “Ground Controlled Directional Bedding Branch Drilling (GCD‐D)” grouting has achieved remarkable results in controlling water disasters.
