Cover Story：Natural gas-gushing scene at the site of well Anye-1. Using integrated geological-geophysical method, researchers carried out systematical investigation of the oil and gas formation and enrichment conditions of Paleozoic strata in southern China, discovered the Anchang favorable synclinal oil and gas potential area in northern Guizhou through evaluation and optimization of the Wuling Mountain mining right blank area and drilled well Anye-1. The in-situ test when the drilling in the Silurian Niulanshan Formation met the barren hole revealed the initial daily output of 420.1 thousand cubic meters of stable high-production industrial gas stream, and the daily output of the completed well reached over 100 thousand cubic meters, thus achieving remarkable breakthrough of oil and gas exploration in the Wuling Mountain area. The research achievement led by Professor ZHAI Gang-yi and BAO Shu-jing, Oil and Gas Resources Survey Center, CGS, ranks the second among “Top Ten Scientific and Technological Progresses of CGS and CAGS in 2015”.
