基于岩心、测井资料及普通薄片、铸体薄片、扫描电镜、X衍射、物性和压汞等化验分析资料,研究了柴达木盆地马北8号构造下干柴沟组下段砂岩储层特征.结果表明:该套储层的储集空间以原生粒间孔为主,夹少量次生粒间孔,储层物性好,排驱压力和饱和度中值压力较低,孔喉半径较大且分选性中等,歪度粗,孔隙结构参数总体较好.储层质量受沉积相和成岩作用的综合影响,其中,辫状河河床及滩坝沉积区为最有利储层发育区,加之压实作用较弱、成岩早期的中等胶结作用和比较普遍的溶蚀作用有利于原生孔隙和喉道的保存及部分次生孔隙和喉道的发育.利用储层物性及压汞等参数,将马北8号构造下干柴沟组下段储层划分为Ⅰ、Ⅱ、Ⅲ类储层,其中Ⅰ、Ⅱ类储层在目前的技术条件下是增储上产的首选储层.     

To Protect the Environment—the Bounden Duty of CNPC

Environmental Protection takes precedence during the production and operation
The idea of ＂humanistic, safety first and environmental protection prior＂ is the basic principle of environmental protection of CNPC. It is pointed out in the work report of CNPC that, ＂To strengthen the safety production, protect the environment and save energy resources is the inevitable requirement to thoroughly implement the scientific approach on development as well as an important aspect to transform the pattern of economic growth＂. To carry out environmental protection priority, the whole process of oil and gas production and the guarantee of national oil and gas supply as well as the sustainable development should be permeated with the work of environmental protection. Specifically speaking, CNPC guarantees the priority of environmental protection with ＂Six Priorities＂ in the process of production and operation.     

Studies on the Reaction Mechanism of CPP and the Factors Affecting the Yields of Ethylene and Propylene

The reaction mechanisms of Catalytic Pyrolysis Process and the ethylene and propylene forma-tion reaction are analyzed,and ethylene and propylene are produced through both the free radical reac-tion and carbenium ion reaction.The factors affecting the yields of ethylene and propylene are discussed.The results showed that greater yields of ethylene and propylene can be obtained on ZSM-5 catalysts rather than USY and REY catalysts,and the modified ZSM-5 could improve the ethylene yield.A higher temperature is favorable for enhancement of the free radical reaction as opposed to carbenium ion reaction,and change in temperature can adjust the ratio of ethylene and propylene production.A higher steam amount could produce more ethylene and propylene and less coke,and lowering the catalyst/oil ratio is favorable for producing ethylene.     

Analysis of the Latest Progress of Methane Emissions Reduction Policies in the European Union and the United States

<正>This paper elaborates on the key points of the latest developments in methane emissions reduction policies in the European Union (EU) and the United States (U.S.) and makes a comparative analysis of their policy frameworks.There are similarities between the EU and the U.S. in terms of methane emissions reduction measures, but there are also significant differences.     

Protector of the “Heart” in the Central Asia Desert

Compressor station personnel: The compressor station is the ‘heart' of the natural gas pipeline; there are 11 compressor stations along the over 1800 km of C line that makes up the Central Asia natural gas pipeline. Only by continually providing power at compressor stations can clean natural gas from Central Asia be transported to inland China.     

Sequence Stratigraphy of the Palaeogene in the HGZ Area of Qaidam Basin

Sequence stratigraphy can be used to predict the oil and gas reservoir bodies and to choose the oil targets. Fan delta and sublacustrine fan systems are developed in the HGZ Area, which is located in front of the Altun Mountain in the west of the Qaidam Basin. On the basis of seismic and well drilling data, the deposits in the area were studied by using sequence stratigraphy and reservoir prediction techniques. Various reservoir prediction techniques used under the constraint of high resolution sequence framework could help to improve the precision of reservoir prediction and to recognize the pinch out line of sand layers, the distribution of isolated sandstone bodies and the types of oil pools. The study of sequence stratigraphy makes reservoir prediction more effective by dividing different scales of sequences and distinguishing the system tracts and parasequence sets, and indicates the internal relationship between oil/gas and sedimentary bodies in different system tracts with evolution in time and space.     

Seismic damage zone and width–throw scaling along the strike-slip faults in the Ordovician carbonates in the Tarim Basin

Understanding the scaling relation of damage zone width with displacement of faults is important for predicting subsurface faulting mechanisms and fluid flow processes. The understanding of this scaling relationship is influenced by the accuracy of the methods and types of data utilized to investigate faults. In this study, seismic reflection data are used to investigate the throw and damage zone width of five strike-slip faults a ecting Ordovician carbonates of the Tarim intracraton basin,NW China. The results indicate that fault slips with a throw less than 200 m had formed wide damage zones up to 3000 m in width. Also, damage zone width is found to have both a positive correlation and a power-law relation with throw of two orders of magnitude, with a ratio of these values varying in a range of 2–15. The relationship between throw and damage zone width is not a simple power-law and changes its slope from small to larger size faults. The results indicate that throw scales well with damage zone width for the studied faults, and hence these can be used to predict fault geometries in the Tarim Basin. The study of the wide carbonate damage zones presented here provides new insights into scaling of large-size faults, which involve multiple faulting stages.     

Oil Futures off the Agenda

Speculation that the domestic oil futures exchange would reopen soon was premature, industry sources said. Beijing-based media indicated on March 4 that the resumption of oil futures was imminent, as part of the government‘s efforts to limit oil price fluctuations over fears of war with Iraq.

Can We Successfully Cross the “Historic Three Gorges” of the Energy Transition

正Since China’s leaders put forward the "30/60" goals in September 2020(achieving peak carbon dioxide emissions by 2030 and carbon neutrality by 2060),how to achieve the goals on schedule has become a hot topic in the whole of society. At present,from the central government to local governments,from the business community to the academic community,and from think tanks to media networks, the discussion around"Carbon Neutrality and Peak Carbon Dioxide Emissions" is in full swing.

Hydrocarbon migration and accumulation along the fault intersection zone——a case study on the reef-t systems of the No.1 slope break zone in the Tazhong area, Tarim Basin

Understanding hydrocarbon migration and accumulation mechanisms is one of the key scientific problems that should be solved for effective hydrocarbon exploration in the superimposed basins developed in northwest China.The northwest striking No.1 slope break zone,which is a representative of superimposed basins in the Tarim Basin,can be divided into five parts due to the intersection of the northeast strike-slip faults.Controlled by the tectonic framework,the types and properties of reservoirs and the hydrocarbon compositions can also be divided into five parts from east to west.Anomalies of all the parameters were found on the fault intersection zone and weakened up-dip along the structural ridge away from it.Thus,it can be inferred that the intersection zone is the hydrocarbon charging position.This new conclusion differs greatly from the traditional viewpoint,which believes that the hydrocarbon migrates and accumulates along the whole plane of the No.1 slope break zone.The viewpoint is further supported by the evidence from the theory of main pathway systems,obvious improvement of the reservoir quality (2-3 orders of magnitude at the intersection zone) and the formation mechanisms of the fault intersection zone.Differential hydrocarbon migration and entrapment exists in and around the strikeslip faults.This is controlled by the internal structure of faults.It is concluded that the more complicated the fault structure is,the more significant the effects will be.If there is a deformation band,it will hinder the cross fault migration due to the common feature of two to four orders of magnitude reduction in permeability.Otherwise,hydrocarbons tend to accumulate in the up-dip structure under the control of buoyancy.Further research on the internal fault structure should be emphasized.
