With the development of computer technology and numerical simulation technology, computer aided engineering (CAE) technology has been widely applied to many fields. One of the main obstacles, which hinder the further application of CAE technology, is how to successfully identify the parameters of the selected model. An elementary framework for parameter identification of a complex model is provided in this paper. The framework includes the construction of objective function, the design of the optimization method and the evaluation of the identified results, etc. The parameter identification process is described in this framework, taking the parameter identification of the superplastic constitutive model considering grain growth for Ti-6Al-4V at 927°C as an example. The objective function is the weighted quadratic sums of the difference between the experimental and computational data for the stress-strain relationship and the grain growth relationship; the designed optimization method is a hybrid global optimization method, which is based on the feature of the objective function and incorporates the strengths of genetic algorithm (GA), the Levenberg-Marquardt algorithm and the augmented Gauss-Newton algorithm. The reliability evaluation of parameter identification result is made through the comparison between the calculated and experimental results and between the theoretical values of the parameters and the identified ones.

Flooding of harmful information on the Internet seriously endangers the physiological and mental health of teenagers. Due to the user-friendliness of the Internet as well as the difficulty in the authentication for the access of specific categories of information, curbing the transmission of harmful information, i.e., assuring the information content security (ICS), has become a reasonable yet challenging alternative. At present, there is an urgent need to develop a systematic model that can effectively carry out the curbing. In fact, curbing the transmission of harmful information by way of filtering can be modeled by access control. In the paper, based on the three core-elements of communication, namely, "Who communicates with whom", "How do they communicate" and "What is the content of communication", we propose a control model, called ICCON. Unlike the existing access control, the reference monitor (RM) of our model is placed in the transmission channel, and moreover, an evaluation frame is proposed, through which the effectiveness of the RM in controlling information transmission on the Internet can be quantitatively evaluated.

Limitation of fault-sealing and its control on hydrocarbon accumulation——An example from the Laoyemiao Oilfi eld of the Nanpu Sag

引用

Petroleum Science 2008年第4期5卷 295-301页

作者： Jiang Zhenxue Dong Yuexia Li Hongyi Liu Luofu Liu Guangdi Li Xiaoying Basin and Reservoir research Center China University of Petroleum Beijing 102249 China State Key Laboratory of Petroleum Resources and Prospecting China University of Petroleum Beijing 102249 China research Institute of Exploration and development Jidong Oilfield PetroChina Tangshan Hebei 063004 China School of Resources and Information Technology China University of Petroleum Beijing 102249 China

Based on previous studies on the internal structures of fault belts, the fault belts in the Laoyemiao Oilfield of the Nanpu Sag can be divided into three units, a crushed zone, an upper induced fracture zone and a lower induced fracture zone according to the log response characteristics. The upper induced fracture zone is characterized by the development of pervasive fractures and has a poor sealing or non-sealing capability. It therefore can act as pathways for hydrocarbon migration. The lower induced fracture zone consists of fewer fractures and has limited sealing capability. The crushed zone has a good sealing capability comparable to mudstone and can thus prevent lateral migration of fluid. Through physical modeling and comparing laboratory data with calculated data of oil column heights of traps sealed by faults, it is concluded that the fault-sealing capability for oil and gas is limited. When the oil column height reaches a threshold, oil will spill over from the top of reservoir along the lower induced fracture zone under the action of buoyancy, and the size of reservoir will remain unchanged. Analysis of the formation mechanisms of the fault-sealed reservoirs in the Nanpu Sag indicated that the charging sequence of oil and gas in the reservoir was from lower formation to upper formation, with the fault playing an important role in oil and gas accumulation. The hydrocarbon potential in reverse fault-sealed traps is much better than that in the consequent fault-sealed traps. The reverse fault-sealed traps are favorable and preferred exploration targets.

石油勘探与开发 1997年第2期24卷 91-95页

作者： Dai Jinxing( Academician of the Chinese Academy of Sciences research Insitute of Petdsm Exploration and development, CNPC, beijing, 100083.

Chinese natural gas Pools (fields) are chiefly hydrocarbon gas pools (fields), with a few of CO2 and a tiny of H2S ones. The gas genetic types are multiple, dominated by oil-type gas and coal-formed gas types,and then followed by other types such as the biogas, mixed gas, H2S-rich gas and abiogenetic gas etc.. The medium-large sized gas pools (fields), in number, account for onIy 13. of the total gas and oil-gas fields in china, but they pes more than 70% gas reserves of the total. The abiogenetic CO2 gas pooIs (fields) are mainly located in the eastern oil-gas bearing basins, such as the Bohai Bay, Songliao, Subei, Sanshui, East china Sea and Zhujiangkou basins etc.. Natural gas pools (fields) tend to develop in or surround the gas generation centers of sedimentary basins.

Acta Geologica Sinica(English Edition) 2007年第4期81卷 605-613页

作者： QIU Nansheng LI Huili JIN Zhijun and ZHU Yinkang 1 State Key Laboratory of Petroleum Resource and Prospecting,china University of Petroleum,beijing 102249 2 Basin and Reservoir research Center,china University of Petroleum,beijing 102249 3 Institute of Petroleum Exploration and development,SINOPEC,beijing 100083 State Key Laboratory of Petroleum Resource and Prospecting China Universityof Petroleum Beijing 102249

Geothermometer is one of the most useful methods to reconstruct the thermal history of sedimentary basins. This paper introduces the application of free radicals concentration of organic matter as a thermal indicator in the thermal history reconstruction of carbonate succession, based on anhydrous thermal simulation results of type I and H1 kerogen. A series of free radicals data are obtained under thermal simulation of different heating temperatures and times, and quantitative modds between free radical concentration （Ng） of organic matter and time-temperature index （TTI） for types I and type H1 kerogen are also obtained. This *** relation was used to model the Ordovician thermal gradients of Well TZ12 in the Tarim Basin. The modeling result is corresponding to the results obtained by apatite fission track data and published data. This new method of thermal history reconstruction will be benefit to the hydrocarbon generation and accumulation study and resource assessment of carbonate succession.

Journal of University of Science and Technology beijing 2003年第3期10卷 76-78页

作者： Shaoqiang Yuan, Shanwu Yang, Wenjin Nie, and Xinlai He Department of Materials Physics, University of Science and Technology beijing, beijing 100083. china Tangshan College, Tangshan 063000, china Dept. of Mat. Phys. Univ. of Sci. and Technol. Beijing Beijing 100083 China Tangshan Coll. Tangshan 063000 China

Transmission electron microscopy (TEM) was applied to investigate theevolution of dislocation configuration and strain induced precipitation behavior during relaxationprocess after deformation in Fe-Ni-Nb-Ti-C-B alloy. Experimental results indicate that thedislocation density is very high and distribute randornly before relaxation. As the relaxation timeincreasing, dislocation cells will form gradually by polygonization. The strain inducedprecipitation retards the progress. In the final relaxation stage, most dislocations get rid ofpinning of precipitates and the cells have developed into subgrains with large size.
