The conception of special geologic bodies has been applied in this study to define and illustrate economic oil and gas reservoirs in sandbodies, which is helpful for hydrocarbon forecast and exploration. Using the comprehensive analysis of drilling, logging, seismic, seismic attribute extraction, and logging constrained inversion in 3D data volume, the special geologic bodies of the Shahejie Formation（Ps^1s） in northern Qikou sag, which have good hydrocarbon potential, are identified and described under the constraint of sequence stratigraphic framework. The dimensions, geometry, and spatial distribution features of the special geologic bodies, as well as their inner architectures and sequence-structure patterns, are also ascertained. The geologic bodies evolved from relative centralization in the middle part of the lacustrine basin in the early stage of Ps1~s Formation, to several dispersive isolated parts in the later stage. This shows a small cycle interval（~2.5 Ma） at the end of the whole transgressive depositional process of Ps1（~7.5 Ma） during the expansion of the lake and relative lake level rise, with the control of sediments supply and fault-related subsidence, which effect the evolution of the sedimentary system. According to the relevance and regularity of the geologic bodies＇ development, different types of potential profitable reservoir traps, including the lithologic lenticular traps, lithologic updip pinchout traps, and structural-lithologic composite traps, can be preserved in the study area. In addition, the internal architecture models provide scientific basis for further hydrocarbon exploration in the frontier basin without enough data.

为了分析沉积物粒度测量结果的影响因素,采用不同的前处理方法以及两种激光粒度分析仪器分析了采自金沙江某考古遗址处的样品,结果表明:(1)富含有机质及碳酸盐成分的深层样品在加入HCl处理后,粒度测量结果偏粗;有机质含量较少的浅层样品经加热处理后粒度偏粗。(2)对同一样品,贝克曼-库尔特激光粒度分析仪对含量相对较少的细颗粒组分更敏感,马尔文激光粒度分析仪对粗颗粒组分的检测效果更好。因此,针对不同沉积环境的样品,应需要采取不同的前处理方法,将所使用的数据建立在同一测量系统内,以期获得更准确的古环境信息。

Studies on basin fills have provided significant insights into reservoir distribution and prediction in petroliferous basins, however, the effect of basin fills on source rock properties has been underexplored. This paper documents basin filling characteristics and their implications for depositional processes and heterogeneity of source rock in the Qingnan subsag of the Jiuquan Basin, by using subsurface geological data from recent hydrocarbon exploration efforts in this area. Drill core data reveals that the basin fill of the Qingnan subsag was dominated by fan delta-lacustrine systems, in which deposition of the fan deltas along the basin margin was mainly through gravity flows. The temporal and spatial evolution of the depositional systems indicates that the basin fill was characterized by a continuously retrogradational process, with decreasing extent of fan deltas in vertical succession. Weakening of tectonic activities and climate change from humid to semi-arid are interpreted to be the main control factors that were responsible for the retrogradational basin fill. The different depositional environments in the early stage and late stage of the retrogradational basin filling history resulted in the different depositional processes and properties of source rocks. This study suggests that source rock heterogeneity associated with basin fills in lacustrine basins should be considered in hydrocarbon exploration.

城市规划是一种具有"契约"性质的公共政策,理应接受信用程度的检讨。城市规划理论上的较高地位遭遇现实的巨大落差,认可和支持度都较低,这种现象表征的是我国城市规划的信用不足问题。本文立足于不完全契约理论,从规划变更入手,探讨了中国城市规划信用受损的原因。主要有三方面的结论:(1)城市规划的本质是不完全契约,规划变更是对规划契约的再调整;(2)规划变更对规划信用的效果分别作用于既有规划和新的规划,以此共同决定着城市规划的信用;(3)城市规划的信用受损主要原因在于城市政府在规划变更中对于不完全契约中"剩余控制权"的积极使用。对此,应该尝试"剩余控制权"的分散和转移;贯彻"有权利必有救济"的法治原则,强化规划事前救济;制度设计不应以减少行政成本为单一准则,而应该重塑城市规划的信用为核心目标,以更精准的公众参与,提升救济的效率。
