New Trends in Oil and Gas Security and Energy Transition

China Oil & Gas 2024年第3期31卷 3-12页

作者： sun longde Zhang Pengcheng Jiang Hang Wang Zugang China National Petroleum Corporation CNPC Economics&Technology Research Institute Research Institute of Petroleum Exploration&Development

The report on the 20th National Congress of the Communist Party of China proposes promoting green development,advancing harmonious coexistence between humans and nature,and ensuring energy security.At COP282023,existing climate targets were reinforced,and a fresh accord was reached for scientifically achieving net-zero carbon emission.The global energy market is being transformed,with oil and gas regaining prominence in energy security.Firms are concentrating on core competencies amidst transitions,though upstream investments show a gradual rebound.The global carbon dioxide capture and storage(CCS)projects has witnessed a significant rise,with Direct Air Capture(DAC)technology gaining attention.Carbon dioxide Capture,Utilization,and Storage(CCUS)is essential as a foundational technology for achieving dual carbon goals.In light of global future development goals and China’s national conditions,this article discusses the evolving trends in the international oil and gas sector alongside China’s domestic energy security landscape.It proposes prospective trajectories for the growth of China’s oil and gas sector and measures to guide and respond to challenges during the energy transition process,providing references for decision-making in the transformation of oil and gas companies.China has a high level of energy self-sufficiency,with the overall energy security situation remaining controllable.China’s oil and gas sector is seeing three-pronged progress:deepening exploration to 10,000s of meters,nano-level reservoir description,and reviving mature fields for a new era.Focusing on deep layer,deepwater,unconventional and mature oilfields,strengthening Belt and Road energy partnerships,enlarging reserves,optimizing pipeline network layout,implementing a smart risk-management ecosystem,and driving the CCUS technology revolution.

Petroleum Exploration and Development 2023年第3期50卷 505-519页

作者： sun longde CUI Baowen ZHU Rukai WANG Rui FENG Zihui LI Binhui ZHANG Jingya GAO Bo WANG Qingzhen ZENG Huasen LIAO Yuanhui JIANG Hangl National Key Laboratory for Multi-resource Collaborated Green Development of Contionental Shale Oil Daqing 163712China China National Petroleum Corporation Beijing 100007China PetroChina Daqing Oilfield Co. Ltd.Daqing 163712China PetroChina Research Institute of Petroleum Exploration&Development Beijing 100083China

Based on the results of drilling,tests and simulation experiments,the shales of the Cretaceous Qingshankou Formation in the Gulong Sag of the Songliao Basin are discussed with respect to hydrocarbon generation evolution,shale oil occurrence,and pore/fracture evolution mechanism.In conjunction with a substantial amount of oil testing and production data,the Gulong shale oil enrichment layers are evaluated and the production behaviors and decline law are analyzed.The results are drawn in four aspects.First,the Gulong shales are in the stage of extensive hydrocarbon expulsion when R_(0) is 1.0%-1.2%,with the peak hydrocarbon expulsion efficiency of 49.5%approximately.In the low-medium maturity stage,shale oil migrates from kerogen to rocks and organic pores/fractures.In the medium-high maturity stage,shale oil transforms from adsorbed state to free state.Second,the clay mineral intergranular pores/fractures,dissolution pores,and organic pores make up the majority of the pore structure.During the transformation,clay minerals undergo significant intergranular pore/fracture development between the minerals such as illite and illite/smectite mixed layer.A network of pores/fractures is formed by organic matter cracking.Third,free hydrocarbon content,effective porosity,total porosity,and brittle mineral content are the core indicators for the evaluation of shale oil enrichment layers.Class-I layers are defined as free hydrocarbon content equal or greater than 6.0 mg/g,effective porosity equal or greater than 3.5%,total porosity equal or greater than 8.0%,and brittle mineral content equal or greater than 50%.It is believed that the favourable oil layers are Q2-Q3 and Q8-Q9.Fourth,the horizontal wells in the core area of the light oil zone exhibit a high cumulative production in the first year,and present a hyperbolic production decline pattern,with the decline index of 0.85-0.95,the first-year decline rate of 14.5%-26.5%,and the single-well estimated ultimate recovery(EUR)greater than 2.0×10^(4)t.In practical exploration a

Petroleum Exploration and Development 2019年第6期46卷 1073-1087页

Daqing 163002China PetroChina Research Institute of Petroleum Exploration&Development Beijing 100083China

Through reviewing the development history of tight oil and gas in China,summarizing theoretical understandings in exploration and development,and comparing the geological conditions and development technologies objectively in China and the United States,we clarified the progress and stage of tight oil and gas exploration and development in China,and envisaged the future development orientation of theory and technology,process methods and development policy.In nearly a decade,relying on the exploration and development practice,science and technology research and management innovation,huge breakthroughs have been made.The laws of formation,distribution and accumulation of tight oil and gas have been researched,the development theories such as"multi-stage pressure drop"and"man-made reservoirs"have been established,and several technology series have been innovated and integrated.These technology series include enrichment regions selection,well pattern deployment,single well production and recovery factor enhancement,and low cost development.As a result,both of reserves and production of tight oil and gas increase rapidly.However,limited by the sedimentary environment and tectonic background,compared with North America,China’s tight oil and gas reservoirs are worse in continuity,more difficult to develop and poorer in economic efficiency.Moreover,there are still some gaps in reservoir identification accuracy and stimulating technology between China and North America.In the future,Chinese oil and gas companies should further improve the resource evaluation method,tackle key technologies such as high-precision 3D seismic interpretation,man-made reservoir,and intelligent engineering,innovate theories and technologies to enhance single well production and recovery rate,and actively endeavor to get the finance and tax subsidy on tight oil and gas.

The clay mineral content of Daqing Gulong shale is in the range of about 35%–45%,with particle sizes less than 0.0039 mm.The horizontal fluidity of oil in Gulong shale is poor,with near-zero vertical flowability.As a result,Gulong shale has been considered to lack commercial value.In recent years,however,interdisciplinary research in geoscience,percolation mechanics,thermodynamics,and surface mechanics has demonstrated that Gulong shale oil has a high degree of maturity and a high residual hydrocarbon content.The expulsion efficiency of Gulong shale in the high mature stage is 32%–48%.Favorable storage spaces in Gulong shale include connecting pores and lamellar fractures developed between and within organic matter and clay mineral complexes.The shale oil mainly occurs in micro-and nano-pores,bedding fractures,and lamellar fractures,with a high gas–oil ratio and medium–high movable oil saturation.Gulong shale has the characteristics of high hardness,a high elastic modulus,and high fracture toughness.This study achieves breakthroughs in the exploration and development of Gulong shale,including the theories of hydrocarbon generation and accumulation,the technologies of mobility and fracturing,and recoverability.It confirms the major transition of Gulong shale from oil generation to oil production,which has extremely significant scientific value and application potential for China’s petroleum industry.
