Palaeogeomorphology and palaeo-environment conditions are the main environmental factors affecting the sedimentation. Due to the frequent water change, complex terrain and high difficulty in seismic identification and tracking, the reconstruction research of palaeogeomorphology and palaeo-environment in the 3rd member of Funing Formation in Qintong Sag of Subei Basin is still insufficient, which affects the overall exploration evaluation of the study area. In order to clarify the palaeogeomorphology and palaeo-environmental conditions of the 3rd member of Funing Formation in Qintong Sag during the deposition period, the formation core, logging data and rock material data are comprehensively analyzed. The semi-quantitative reconstruction of the palaeogeomorphology of the 3rd member of Funing Formation is carried out by combining the palaeo-geologic map, impression method and residual thickness method, and the pyrolysis experiment data, TOC and trace element content data of 33 rock samples from two wells are selected to carry out the palaeo-environment reconstruction analysis. Accordingly, paleogeomorphology reconstruction in map form and the curves of palaeo-environment changes of the 3rd member of Funing Formation in Qintong Sag are drawn, which prove that the study area is a half-graben, lower in the South and higher in the North with the convergence across the east-west direction, the climate is warm and humid during the sedimentary period, the water body activity is frequent and recurrent, the water salinity is low, the multiple source is supplied intermittent, the material source input continues to increase, and the deposition rate is fast. Therefore, the corresponding relationship between stratigraphic physical parameters and paleogeomorphology, geochemical parameters and paleoenvironment in the study area are clarified, which provide reference for the further exploration and development.

The Malang sag lies in the middle of Santanghu basin. In order to divide the base-level cycles of different orders in detail and build the framework of the high resolution sequence of Jurassic in the Malang sag of Santanghu basin. Taking the high resolution sequence stratigraphic theory as a direction,multiple analysis methods were adopted, including core, log well and outcrop profile, etc. The Jurassic of study area can be divided 3 long,6 middle and 18 shaort base-level cycles. The short base-level may be divided two types of cycles that consist of six subtypes;The middle and long base-level cycles are usually of symmetric structures;The long base-level controls the distribution and evolution of sediment facies, and also has a significant influence on the source-reservoir-cap rock assemblage.

Urban villages are the main gathering places of lfoating people, but housing problem of the lfoating people is often ignored in urban village renovations. This paper analyzes the living preference of the lfoating people in several typical urban villages of Shenzhen. Then the author puts forward a new pattern of urban village renovation given the beneifts of the lfoating People. This paper has theoretical and practical signiifcance to urban village renovations.

Starting with the concept of urban texture, this article intends to recognize urban space through human behaviors. Taking Qingdao classical urban district as example, this article analyzes the relationship between the urban texture and public space, explodes urban texture’s composition and probes into the design conceptions of public space. It proposes the design paths of modern public space:In accordance with the city planning idea and under the premise of functional requirements, the design of public space needs to pay more attentions to the quality of living space and humanistic design methods. This article aims at providing some suggestions and references to the construction of contemporary urban public space.

The fast growth of cities presents new challenges and opportunities for preservation of our historic urban area. We should combine preservation with development by protecting the historical heritage and transfer its functions to realize revival at the present age. This paper puts forward a new approach called“3D”, joining the POD, SOD and AOD theory together to carry out great renewal of historic urban area. The”3D approach”is applied to the Protection Plan of Shantou’s old city area, and achieves desirable results. Overall, this paper contributes to the research of preservation of our historic urban area and its practice.

The idea of making a perpetual motion machine comes from around the A.D.1200 in India.After over 600 years,there are some people still try hard to create this kind of installation.In fact with the discovery of the law of conservation of energy and the second law of thermodynamics by scientist,the first kind of perpetual motion machine and the second kind of perpetual motion machine have already been judged a death penalty by final judgment.However,with the continuous progress of human civilization,will the third kinds perpetual motion machine be able to be made out by people? Will the third law of thermodynamics be able to be discovered by the scientist?

Can we make "the third type of perpetual motion machine"?In the article three examples with the fact are used to explain the view.The third type of perpetual motion machine does not violate any existed scientific laws in theory.We will make good use of the renewable sources of energy effectively which is wasted in vain once technology develops to a considerable degree of maturity.That means a substantial increase of the utilization of renewable sources of energy,so that we can have the motionless things which do not eat anything moving forever.

Comprehensive using dataof outcrops,well logging and core,the unconformity of the Permian top Jiamuhe formation were studied in Junggar basin.It is indicated that unconformity is the integratedgeological terrawith the spatial structure,including the normal sediments layer,weathered clay layer and weathering leached layer.According to differences of combinations of each textural layer,the unconformity of top Jiamuhe formation can be integrated into two types:the type-I and the type-II.The type-I has three fully development layers with asandwichstructure,which is widely distributed in the plane.The type-II has two layers,with adouble layer structure and missing the middle of the weathered clay,which is mainly distributed near Ke-Bai fault and Jiamuhe pinch.Utilizing the result of the oil and gas exploration,reservoir controlling of each textural layer were analyzed.The results suggest that the weathering leached layer and normal sediments layer composed of sandstone(conglomerate)can be used not only as channels for petroleum migration,but also as areservoir of oil-gas accumulation.However,the thickness of weathe-ring leached layer is commonly less than 300m,and the oil and gas are prone to accumulate in the region of more than 100m.Weathered clay and mudstone in normal sediments layer is the sealing conditions for oil-gas accumulation in underlying strata.

Aim To discuss the relationship of diagenesis and porosity evolution in Malang Depression.Methods Based on field exploration and information collection,analyge diagenesis and porosity evolution of sandstone,combining the analysis of slice identification,scanning electron microscope,X-ray diffraction,cathodoluminescence,mercury penetration,moldic pore,pyrogenation,reflectivity of vitrinite,fluid inclusions,etc.Results Types of diagenesis,division of diagenetic stage and characteristics of porosity evolution were ascertained.Conclusion Types of diagenesis in the Middle-Upper Jurassic include compaction,cementation,dissolution;the diagenetic stage of reservoirs in the Middle-Upper Jurassic was in the period from A-substage of early diagenesis to A-substage of middle diagenesis;the development and types of porosity of reservoirs was induced by diagenesis evolution of different formations.
