Abstract: Through the research on actual measurement 106km geological profile, the hydrocarbon source rocks mainly develop the third member of Jiufotang formation, followed by the second member. There are five distribution areas where have been divided hydrocarbon source rocks thickness is more than 400m in study area. Among them, Jiufotang area has the greatest sedimentary thickness of hydrocarbon source rocks, while Siguanyingzi-Sanjiazi area has the largest area where hydrocarbon source rocks are more than 400m. Oil shale is good hydrocarbon source rock, while dark gray and black gray mudstone (or shale) are relatively poor. The fan delta front subaqueous distributary channel and mouth bar are well-developed in basin’s fault zone and also the important favorable reservoir, followed by braided delta front mouth bar, subaqueous distributary channel and distal bar developing in northwestern area of the basin. There are four forms of source-reservoir-cap combination: (1) hydrocarbon source rock in the above layer and reservoir in the below layer; (2) hydrocarbon source rock and reservoir in the same layer; (3) normal form; (4) fingerlike intersection. The combination of fingerlike intersection is the most important forms in study area. Fan delta facies next to lacustrine facies is favorable exploration area.

Abstract: According to the theory of reservoir architectural structure and sedimentology, applied the hierarchy analysis, pattern guidance and performance verification methods, taking the South-Two area for example, with the cores, logs and performance, we have done some quantitative research on the parameters of composite channel sand bodies, single point bar sand bodies and the lateral accretion bodies on point bars in South two area, built Three-dimensional model of point bars. Study shows that the point bar sand bodies in PI2a unit are meandering point bar sand bodies formed by the lateral accretion of distributary channels in coastal delta distributary plain. The space combination model of lateral accretion bodies is horizontal-obique type. The width of lateral accretion bodies is 38.5~54m, the average dip of lateral accretion layer is 9.5°, and separation of lateral accretion layer is about 15m. The features above shows the spatial distribution of the lateral accretion body on point bars. With the changes of seepage field and gravity, the influence to remaining oil of lateral accretion layer has been analyzed. Numerical simulation and performance showed that the main concentration of remaining oil is in the upper of the point bar lateral accretion body, proposed the principles and methods of horizontal wells in the point bar sand bodies to tapping potential remaining oil, which provide a theoretical guidance to domestic similar fine reservoir description and the remaining oil tapping.

Abstract: Shijiazhuang is an important industrial city in China,and it is also one of the cities of extremely water scarcity. With the rapid development of econnomy, the water for industrial use is growing increasingly,which leads to a sharp contradictions between demand and supply of water resources. Based on the theory of recycling economy, recycling use of industrial water in Shijiazhuang is one of the best ways to relax the contradiction between the water supply and demand, and finally promote the sustained socioeconomic development.

Abstract: To identify potential energy savings and improvements to thermal comfort in the Canadian residential sector, a survey on occupant behaviour and control of thermal environment was conducted from April-June 2009 in low-rise dwellings in Ontario, Canada. A total of 396 completed responses were received. Survey results show that approximately 20% of the respondents were not satisfied with their room temperature in the winter. Inadequate level of controllability to room temperature is perceived as the most serious problem. Problems associated with overheating during the winter and overcooling during the summer was also identified. Observations from the survey results helped identify the deficiencies of the heating equipments built today and suggest improvements should be made to increase the controllability of current systems. Thermal simulation was then conducted to identify the problems with single-zone systems commonly built today, and to investigate the potential retrofit alternative. Simulation results show that a multi-zone system can effectively mitigate the deficiencies suffered by existing systems and can drastically improve the energy performances of houses.

Abstract: With the rapid economic development in China, the domestic copper demand grows sustainedly and drives the continual expansion of China copper industry. The study is based on the industry lifecycle theory and supported by the lifecycle characteristics of non-ferrous metal industry of the current developed countries. Combined the experienced data of early developed industrial countries to our practical situation, the growth trend and development limitation of China copper industry lifecycle are analyzed by the growth curve model, which is significant for the accord development of China copper industry.

Abstract: In the light of more and more serious water hazard problems in Huangling mining area, according to analyze the hydrogeology condition and water-filling factors of Huangling No.2 mine, this paper selected the formula in the Standard on the Exploration of Hydrogeology and Engineering-Geology in the Mining Area (GB12719-91) (Standard for short) to calculate the height of water flowing fractured zone in coal seam No.2. On the basis of the Shangzhenzi and Baiyaogou water source, a scientific risk evaluation system for the roof water-bursting condition during mining coal seam No. 2 is established, and a division scheme for the condition is also put forward. The paper points out that a water inflow risk area is composed by 14 drillings (R65, Fx1, Fx7 and so on) which is approximately 30.6km2 in the southwest of predate mining district. The study provides basis for carrying out “The twelfth five-year plan” of the mine.

Abstract: Through analysis on oil and gas accumulation characteristics, the vertical and horizontal distributions of reservoirs were summarized and the controlling factors of oil and gas accumulation were discussed in this paper. It is considered that reservoirs of Shuang 1 Member mainly distribute in Jianshan structural belt; the structural high or structure slopes are favorable accumulation zones, and the oil and gas accumulation and distribution is obviously controlled by local fault noses or fault block trap structures; the oil and gas always distribute near sequence boundaries; sublacustrine fan and fan delta sandbodies are favorable reservoirs for oil and gas accumulation; the normal fault sealing is very important for oil and gas accumulation of the Shuang 1 Member.

Abstract: The insulating layer and interlayer are the main factors to form the heterogeneity in the Continental reservoir. According to the reservoir geological features in Funing Formation of Gaoji Oilfield, combined with characteristics of sedimentary environment and diagenesis, we carry out classification and feature description for the insulating layer and interlayer in the research area. The spatial distribution of insulating layer and the interlayer is on the basis of analyzing the log response characteristics of the single well. With the impact of reservoir heterogeneity, we further elaborate the distribution of insulating layer and the interlayer and remaining oil in the relationship.

Abstract: As the result of its special structural feature and depositional setting, Ordos Basin formed large scale low-permeability reservoir. According to scanning electron microscope, casting sheet image, core observation, physical property analysis and core analysis testing, this paper summarized and analyzed ultra low permeability reservoir microscopic feature of Ordos Basin Baibao area Chang63. Reservoir microscopic feature is controlled by deposition and diagenesis. Deposition decided reservoir lithology, interstitial content and sizes of primary pores. Compaction and cementation of diagenesis destroyed primary pores, but denudation provided high range secondary pores, which improved storage space of the research area.
