On July 17th, Changqing Oilfield Company was informed that Changqing Oilfield took the lead in the large scale of Ordos Basin at the National Eleventh Five-Year Plan project acceptance and “Twelfth Five-Year†contract review meeting held by the relevant national ministries in Beijing. The results of the "Eleventh Five-Year Plan" for the exploration and development demonstration project of lithologic formations and the content of the "Twelfth Five-Year" contract for demonstration projects were highly evaluated by the participating experts and agreed to pass the examination and acceptance.
The major science and technology projects of “Large Oil and Gas Fields and Coalbed Methane Development†is one of the 16 major special projects of the country and is organized and implemented by China National Petroleum Corporation and Zhonglian Coalbed Methane Co., Ltd., PetroChina, Sinopec, CNOOC and Zhonglian. Coal shared responsibility, set up 43 projects and 22 demonstration projects. Since the implementation of the exploration and development demonstration project of large lithologic formations in the Ordos Basin undertaken by Changqing Oilfield, a number of exploration and development supporting technologies and two landmark technical achievements have been formed, and some of the achievements have participated in the “Eleventh Five-Year†national major scientific and technological achievements exhibition. Among them, the large-scale gentle slope type delta deposition model, the innovation of genesis model of the inland depression basin sand body, and the development of the non-Darcy seepage theory, lay the foundation for the exploration and development of low-permeability oil and gas reservoirs; low-permeability oil layers multi-stage sand and multi-stitch pressure The original innovative technologies such as splitting technology and medium-low pressure gas gathering in tight sandstone gas fields have broken the monopoly of foreign technologies and reached the international advanced level; all-digital multi-wave seismic reservoir prediction, horizontal wells without hydraulic column sandblasting and multi-stage fracturing processes, etc. Re-innovation technology has filled in the gaps in domestic technology; integrated innovation techniques such as logistic quantitative evaluation and advanced water injection in low-permeability reservoirs have important demonstration significance.
The key core technologies obtained from the “Exploration and Demonstration Project of Large Lithologic Formation Reservoirs in the Ordos Basin†provide strong guarantees for the formation of a national major oil and gas major technical series, and promote the rapid development of the Sulige tight gas reservoir and the ultra-low permeability reservoirs in Jidong. , increase the scale of production and production, to achieve "production, learning, research, use," the organic integration.
