A dynamic performance evaluation method based on SD-BSC

Taking into consideration the disadvantage of Balanced Scorecard(BSC)not being able to reflect time delay,nonlinear problems of causal relationship and being lack of effective simulation,we combined it with the characteristics of the System Dynamics(SD).Basing on the background of manufacturing enterprises,through SD integrating with the BSC we established a new performance evaluation method-SD-BSC method to overcome the disadvantage of BSC.A performance evaluation model of SD-BSC is provided and the simulation results are analyzed which show different production policies will lead to different customer's satisfaction degrees.The SD-BSC dynamic performance evaluation method can reflect dynamic,complex causal feedback relationship and time delay,so it compensates for the disadvantage of traditional financial performance evaluation method,and at the same time makes the BSC perfect.     

A new evaluation method of gel’s dynamic sealing characteristic in porous media

Water shutoff through injection wells is one of the most important techniques used for water injection profile control and modification in severely heterogeneous reservoirs, aiming at stabilizing oil production. It has been widely reported that the effectiveness and efficiency of water shutoffusing gel is mostly dependent on the gel dynamic sealing properties in the porous media. Firstly the gelation strength and gelation time of polymer gel were evaluated. Then, core flowing experiments were conducted before and after gelation in a 32 m long sand pack. In addition, water flooding core experiments were also carried out in a long core of 80 cm before and after injecting gel system to check the reliability of this evaluation method. The experimental results show that moderate-strength gel can be formed at 65 ~C. According to the integrated evaluation of the plugging coefficient, plugging strength and water breakthrough time, the gel particles are capable of migrating to a distance of 7.47 m from the injection point of the 32 m long sand pack during the water injection process after gelation. Based on sands gelation status and effluent analyses, the effective migration distance of the gel particles is 4-14 m. Through the core flooding experiments using the 80 cm heterogeneous core, it is evidenced that the gel can be formed in the deep reservoir （40.63% of total length） with the plugging strength as high as 6.33 MPa/m, which leads to extra oil recovery of 10.55% of original oil in place （OOIP） by water flooding after gel treatment.     

Quality evaluation of layerlike backfilling and flow pattern of backfill slurry in stope

Stability condition and quality evaluation formula of layerlike backfilling roof,Q≥C,where Q denotes is quality index depending on allowable compressive or tensile strength and integrity of backfilling,and C is the technical index depending on mining method and backfilling technology,were inferred according to simply supported beam theorem.Technical treatment measures for instable backfilling roof,including optimum of appropriate filling materials and dosage for excellent flow property and reduction of backfill cost.It is proved that slope equation of backfill slurry in a stope to be filled is y=hexp[x2/(2σ)2)],where h is height of cone and σ2 is mean square,and that optimum drainage point of backfill slurry can be determined by the equation and sizes of stope.Case study indicates that the results can give a theoretical support for quality evaluation and control of layerlike backfilling.

Real Estate in Chongqing as a Pillar Industry：A Quantitative Analysis

The definition of pillar industry is stated and its indicators, including the proportion of added value in the GDP, the degree of industry correlation, the income elasticity of demand, and the growth rate of employment will be discussed. And then index weighing is determined based on the degree of importance. The result of the quantitative analysis of real estate industry in Chongqing suggests that its first three evaluating indicators live up to the index requirement of a pillar industry while its degree of industry correlation is not satisfactory. An overall evaluation indicates that the real estate industry in Chongqing meets the requirements of pillar industry.
