In the more than one hundred years since the discovery of volcanic rocks, there have been problems of discovery, control, and development. This passive situation will now be changed. On the 23rd, the reporter learned that after nearly a decade of research, China’s volcanic seismic exploration technology has achieved breakthroughs. Using this technology, only 170 million tons of crude oil and 41.6 billion cubic meters of natural gas were found 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 has gradually attracted attention. According to news from the China National Petroleum and Chemical Industry Federation’s organization appraisal meeting, the company has passed through the China Petroleum Group’s Eastern Geophysical Exploration Company. In the past ten years, CNPC Xinjian Oilfield Company has used volcanics seismic exploration technology to efficiently identify a number of volcanic reservoirs with large reserves. In addition, 30% of the inefficient wells have been developed for developed gas reservoirs. The shift to high-efficiency wells.
The key breakthroughs in key seismic exploration techniques for volcanic reservoirs and high-efficiency practices in the Junggar Basin have been highly evaluated by the experts of the appraisal committee and believe that the project results have made important contributions to the scale storage and stable production of volcanic rock reservoirs in the Junggar Basin. The exploration and development of volcanic reservoirs in the west have important guiding significance.
According to reports, in 2005, the Xinjiang Oilfield conducted an in-depth study on the basement of the Junggar Basin, and proposed that the Carboniferous volcanic rocks have great potential for oil and gas exploration and development. To this end, the Eastern Geophysical Exploration Company and the Xinjiang Oilfield Branch have formed a joint research team since 2006. Targeting the difficult points and targets of oil and gas seismic exploration in volcanic rocks in the Junggar Basin, the breakthroughs in many seismic exploration techniques have been overcome. It has been suggested that volcanic oil and gas reservoirs are mainly 'non-homogeneous hydrocarbon reservoirs' new understandings and new concepts, which break the limitations of traditional oil and gas reservoirs. Sexuality, breaking the traditional concept of volcanic rock looking for oil for the restricted area.
