Abstract: Serious borehole collapse has occurred in shale below salt formation of Fauqi oilfield in Iraq. The Lots of bedding shale cavings returned to ground. The strength of bedding shale cores with different bedding dip angle are tested, which changes along in a high degree with the dip angle and reach the minimum in 50°-60°. The experimental results are regressed by different strength criterion, which demonstrate that McLamore strength criterion is more accurate. The collapse pressure of shale below salt formation is calculated by Mohr-Coulomb criterion and McLamore criterion respectively. The maximum collapse pressure by Mohr-Coulomb criterion occurs in the maximum in-stress orientations and 90° deviation angle, and that by McLamore criterion occurs in the maximum in-stress orientations and 50°-60° deviation angle. By analyzing the actual drilling situation, McLamore criterion is proved to be more accurate and can be used in Fauqi oilfield.

Abstract: This paper analyzed the glutenite reservoir pore structure characteristics and percolation mechanism, according to the normalized permeability curves, combining the NMR. The 100% water production rate’s displacement volume was taken as a benchmark and with the concept of water flooding control degree a more concise empirical formula was given where the water production rate changed with the recovery degree and water flooding volume coefficient. The examples of two blocks of Karamay oilfield agreed well with the production practice, clearly defined the direction of subsequent water flooding development work.

Abstract: Salt and anhydrite formation of Fauqi oilfield in Iraq contains salt, anhydrite and shale. Complex situations have occurred in drilling process, such as overflow and sticking. The cores of the three lithology rock are fetched and their strength and creep mechanical properties are tested. Anhydrite is with higher strength and lower creep properties, and shale and salt is with lower strength and higher creep properties. The collapse pressure and fracture pressure of the three lithology rock are calculated. The safe density window of anhydrite is the most widest and there is no risk of wellbore instability, and the safe density window of shale is the narrowest and wellbore instability easily occur. The low limit of mud density to prevent shale and salt creep are calculated by power law model. The safe drilling density window is determined and successfully applied in drilling field.

Abstract: In this paper, the effect of sodium hexametaphosphate on the hematite was studied and the mechanism was analyzed. The results indicated that under the condition of the optimal grinding medium, compared with the result without sodium hexametaphosphate added, with citric acid added at the mass of 0.30% of the hematite, the content of-0.074mm of grinding production was increased by 6.38%; physical adsorption and chemical adsorption which were on the surface of hematite produced by sodium hexametaphosphate can reduce viscosity of grinding pulp, change surface potential of the hematite, and reduce the hardness on the surface of the hematite. Therefore citric acid can improve the grinding efficiency of the hematite.

Abstract: Eco-civilization of water and human-water harmony supplement each other and advance each other. Constructing eco-civilization of water is an important way of promoting the development of modern water conservancy. It is necessary to establish national notion of saving water, handle the relationship between water conservancy project construction and water ecology, and improve conservation system of water ecology to strengthen the construction of eco-civilization of water and realize the harmonious development of human and water.

Abstract: With the development of economy, the rapid commercial and residential development of China's domestic. In the contemporary Chinese, many problems have designed many new residential areas. There are imitation, lack of style characteristics alone, poorly designed, designers and builders out of line and other issues. Through correlation analysis of Residential Landscape Design, presented various solutions.

Abstract: The SWOT method was used to evaluate water scenery resources from the strength, weakness, opportunity and threat, according to the resource survey results of nature, human, society, economy, water resources and water projects of the water scenic park,in order to strengthen the construction and management of the canal water scenic park in Linqing. The results show that the current situation of scenery resources is generally good, but there are also many problems, such as the characteristics of tourism products need to be taped etc. Thus some suggestions are put forward for the construction and development of the water scenic park.

Abstract: Through to the street corner space of the urban residents' daily life experience of social investigation, put forward the guiding principles for the location of corner space landscape design can identification, space versatility, use safety, environment suitability principle. Conclusion from the location awareness, zoning, personality construction and processing in the detail design method. For waterscape design, plant configuration, pavement and recreation facilities such as the design of the landscape elements to improve the edge space landscape quality present situation, the cultural connotation and aesthetic value, improve environment conducive to the development of spiritual civilization.

Abstract: With the development of human society, people’s requirements on landscape environment have been increasingly higher. Waterfront landscape, as the important component of a city, shall not only demonstrate the natural beauty of natural landscape but also the ecological and humanistic beauty of human landscape. This paper finds out the related principles and design methods to integrate regional culture into the design of waterfront landscape through analyzing the concepts and content of waterfront landscape.

Abstract: With rapid economic development in China and input into primary educational facilities, outdoor environment of middle school campus has also increasingly drawn attention from people from all walks of life. In spite of this, we still have many problems and misunderstanding about outdoor environment of middle school campus in the aspects of cognition and actual construction. Based on the example of Shenzhen Foreign Languages School (Senior High School), this paper has introduced and analyzed its outdoor environment space of campus and summarized spatial processing methods finally to demonstrate existing problems in the outdoor environment design of campus, including safety and function problems, excessive attention to expression of campus culture and restriction of base conditions.
