油层水洗级别的热解气相色谱定量判别

应用热解气相色谱资料开展水淹层评价是储层地球化学研究的一个新领域，目前，这方面的研究尚处于定性评价阶段。文章选择位于渤海湾盆地黄骅坳陷的港东油田和羊二庄油田新近系开发层系（包括馆陶组和明化镇组）为研究目的层，以岩心热解气相色谱分析为手段，开展了油层水洗级别的气相色谱定量判别的尝试。在系统分析各气相色谱参数的地质意义及其与油层水洗的关系的基础上，优选出合理的评价参数，并采用交会图技术建立不同级别水洗油层的定量判别标准，通过其他评价方法的验证，表明该定量判别方法具有实际应用价值。     

孔西潜山奥陶系原生油藏成藏时期探讨

黄骅坳陷孔西潜山发现奥陶系（孔古3井、孔古7井）低产原生油藏和石炭-二叠系原生油气藏（孔古4井），油源对比结果证明，前者原油主要源于中奥陶统马家沟组灰岩，后者油气主要源于石炭系太原组及二叠系山西组煤系泥岩。根据孔古3井油藏的两期流体包裹体及储集层自生伊利石K-Ar年龄测定结果，油藏属两期成藏，第一期为晚三叠世（距今222.51～240.34Ma），第二期为第三纪，以晚第三纪为主。     

黄骅坳陷白水头-唐家河地区东营组地层地震模拟及响应曲线分析

根据对黄骅坳陷白水头—唐家河地区东营组钻井资料的统计分析，设计了3种不同地质模型．用于分析不同厚度、不同孔隙度和不同流体性质的储层所表现出的地层速度和密度特性，进而通过地震正演模拟研究，得到不同储层参数状况下的响应曲线。分析响应曲线发现，在该地区，当含水砂岩厚度为20m时．其地震反射振幅最大；而含油帮岩在厚度为18m时达到最大。当孔隙度达到22％时．含油砂岩的地震反射振幅会发生极性反转；而含水砂岩在孔隙度为28％时极性反转。这就为该地区的地震储层预测提供了依据。     

成藏流体历史分析——以黄骅坳陷三马地区为例

应用储集层岩石烃类流体包裹体研究方法，对黄骅坳陷三马地区沙一段油藏进行了重建成藏流体历史的尝试。对包体流体状态的分析表明，成藏流体具有高密度，高矿化度的性质，被捕获时的温度约为110－140℃，成藏流体的主要充注时期在明化镇组沉积期，距今为10－4Ma之前，充注成藏后的小幅度构造抬升中可能使原称油水界面以下的地层水矿化度发生变化，导致现今储集层流体矿化矿比包裹体流体矿化度明显下降。图5表2参6（钟宁宁摘）。     

Subtle traps prediction using sequence stratigraphy and 3D seismic technology: A case study from Qikou depression in Huanghua basin

Forecasting subtle traps by sequence stratigraphy and 3D seismic data is a sensitive topic in hydrocarbon exploration. Research on subtle traps by geophysical data is the most popular and difficult. Based on the sufficiently drilling data, log data, core data and 3D seismic data, sediment sequence of Qikou depression, Huanghua basin was partitioned by using sequence stratigraphy theory. Each sediment sequence system mode was built. Sediment faces of subtle traps were pointed out. Dominating factors forming subtle traps were analyzed. Sandstone seismic rock physics and its response were studied in Tertiary System. Sandstone geophysical response and elastic modulus vary laws with pressure, temperature, porosity, depth were built. Experimental result and practice shows that it is possible using seismic information forecasting subtle traps. Integrated using geology, log, drilling data, special seismic processing technique, interpretation technique, high precision horizon calibration technique, 3D seismic visualizing interpretation, seismic coherence analysis, attribute analysis, logging-constrained inversion, time frequency analysis, subtle traps object is identified and interpreted. Finally, advantage object of subtle trap in this area was determined. Bottomland sand stratigraphic and lithologic reservoirs in Qinan slope zone have been founded by means of high resolution 3D seismic data field technique, high resolution 3D seismic data processing technique and seismic wave impedence inversion technique.

黄骅坳陷埕海地区奥陶系天然气成因研究

黄骅坳陷埕海地区奥陶系天然气地球化学特征较为特殊,具有非烃含量高、稳定同位素重的特征。通过同位素特征,进一步结合地质、地化资料综合分析,对埕海地区奥陶系天然气的成因类型和气源进行探讨。认为埕海地区奥陶系天然气为煤成气,主力气源岩为石炭-二叠系烃源岩。     

Spatial practice,conceived space and lived space: Hong Kong’s ‘Piers saga’ through the Lefebvrian lens

By applying the Lefebvrian lens, this paper tries to understand why unlike previous similar cases, the latest removal of the Star Ferry and Queen’s Pier was so controversial. To Lefebvre, embedded in ‘spatial practices’ that ‘secrete’ a place are two contradicting spaces: ‘conceived spaces’ produced by planners to create exchange values and ‘lived spaces’ appropriated by citizens for use values. Applying Lefebvre’s framework to examine the ‘Piers saga’, it is found that the pre‐Second World War (WWII) piers were ‘conceived’ by spatial practices of a colonial and racially segregated trading enclave. The public space in the commercial heart that housed the previous generations of piers was not accessible to the Chinese community, thus denying them opportunities to appropriate them and turn them into ‘lived’ spaces. It was only after WWII when the Government carried out further reclamation to meet the needs of an industrializing economy that inclusive public spaces were conceived in the commercial heart, enabling the general public to ‘appropriate’ them as ‘lived’ space. When the Government planned to remove this very first ‘lived’ space in the political and economic heart of the city to conceive further reclamation for the restructuring economy, the more enlightened citizens were determined to defend it.
