In the more than one hundred years since the discovery of volcanic rock, there have been problems of discovery, control, and development. This passive situation will now be changed. On the 23rd, the reporter was informed that after nearly a decade of research, China's volcanic seismic exploration technology has achieved breakthroughs. With this technology, only 170 million tons of crude oil and 41.6 billion cubic meters of natural gas have been discovered efficiently in volcanic rocks in the Junggar Basin.
With the shrinkage of oil and gas resources in clastic rocks and carbonate rocks, the exploration and development of volcanic oil and gas resources have gradually attracted attention. The news from the results appraisal meeting organized by the China Petroleum and Chemical Industry Federation stated that after nearly a decade of research by the China National Petroleum Corporation’s Eastern Geophysical Exploration Company and China National Offshore Oilfield Co., Ltd., the use of volcanic seismic exploration technology has been highly effective. A group of volcanic rock reservoirs with scale reserves, in addition, a 30% conversion of inefficient wells to high-efficiency wells has been developed for developed gas reservoirs.
The breakthrough in the “Key Seismic Exploration Technology for Volcanic Reservoirs and High Efficiency Practice in the Junggar Basin†project was highly appraised by the appraisal experts and concluded that the results of this project have made important contributions to the scale storage and stable production of volcanic rock reservoirs in the Junggar Basin, and to the east of China. The exploration and development of volcanic reservoirs in the west have important guiding significance.
According to reports, in 2005, Xinjiang Oilfield conducted an in-depth study on the basement of the Junggar Basin, and proposed that the Carboniferous volcanic rocks have huge oil and gas exploration and development potential. For this reason, the Eastern Geophysical Exploration Company and the Xinjiang Oilfield Branch have formed a joint research team since 2006. Targeted the difficult points and targets of oil and gas seismic exploration in volcanic rocks in the Junggar Basin, breaking the bottleneck of many seismic exploration technologies, and proposing that volcanic oil and gas reservoirs are mainly new understandings and concepts of “non-homogeneous oil and gas reservoirsâ€, which breaks the limitations of traditional oil and gas reservoirs. Sex, break through the traditional concept of volcanic rock looking for oil for the restricted area. (Reporter Zhu Xi)
