The salt beds of Lower Tertiary developed in the mid-segment of Kuqa foreland fold belt, northern Tarim basin. They considerably controlled structural deformation of the belt. Ac- cording to the field observation, seismic profile interpretation and drilling data, three different structural styles of supra-salt, intra-salt and sub-salt occurred in the Kuqa foreland fold belt. Su- pra-salt structural styles mainly include thrust faults and fault-related sags. Intra-slat structural styles essentially are salt-pillows, intra-salt faults and folds, and salt weld structures. Sub-salt structural styles mainly consist of imbricated thrust faults, duplex structures, pop-up and fault-related folds. It is indicated that great differences exist among supra-salt, intra-salt and sub-salt structures of Kuqa foreland fold belt. The salt-related structures were formed in the same structural stress field. The dynamic mechanism of the salt-related structures is mainly associated with gravitation, compression and plastic flow of salt beds.

Petroleum Science 2011年第2期8卷 170-176页

作者： Yue Wenzheng Tao GUo Chai Xiyuan Jiang Hongxiu Mu Hongwu State Key Laboratory of Petroleum Resource and Prospecting China University of Petroleum Beijing 102249 China Key Laboratory of Earth Prospecting and Information Technology China University of Petroleum Beijing 102249 China CNPC Key Laboratory of Well Logging China University of Petroleum B eijing 102249 China Bohai Drilling Engineering company ltd.Logging company Tianjin 300280 China

The Lattice Gas Automation （LGA） method, which is improved by introducing a reflection coefficient for the border between phases to show its effect on current path, is used in this paper to simulate the current flow in digital rock for investigating the effects of clay content and clay distribution types on the relationship between formation factor（F） and rock porosity（φ）. The digital rock model is constructed by simulating a natural deposit of matrix particles with different shapes and radius. Based on the simulation results, it was found that both dispersed clay and laminated clay can lead to a non-Archie relationship of F-φ. The non-Archie effect of laminated clay on the F-φ relationship was more significant than that of dispersed clay. Moreover, a realistic model is developed in this work for quantitatively describing the effect of clay content （Denoted as Vsh） on parameters a and m. These study results have further demonstrated the validity of LGA in study of electrical transport properties at a pore scale.

A Pragmatic Approach to Product Costing Based on Standard Time Estimation

引用

Journal of Systems Science and Systems Engineering 2001年第2期13卷 197-202页

作者： JIAO Yuan-yuan, HAN Wen-xiu, DU JunSchool of Management, tianjin University, tianjin 300072, china School of Management Tianjin University Tianjin 300072 China

The major drawbacks of traditional approaches to product costing include lack of manufacturing knowledge, reliance on the detailed design description, poor cost function approximation and inability to update estimation algorithms by using actual cost data. Adopting the Activity-Based Costing (ABC) concept and based on estimated processing time, this paper proposes a pragmatic approach to product costing. The approach involves two stages, namely the preparatory stage and the estimation stage. A case study conducted in a refrigerator company is reported.

First Application of Novel Sulfiding Agent SZ 54 in Domestic Hydrofining Unit

引用

china Petroleum Processing & Petrochemical Technology 2006年第4期000卷 23-28页

作者： Pan Maohua (Zhenhai Refining and Chemical Stock company, ltd., Ningbo 315207) Zhenhai Refining and Chemical Stock company Ltd.Ningbo 315207

A novel environmentally friendly sulfiding agent SZ 54 was for the first time used for presulfidation of the catalyst in the 2 Mt/a hydrofining unit at Zhenhai Refining and Chemical company. The application results had shown that the sulfiding agent SZ54 had low smell, high flash point, and safe and environmentally friendly features. The lower decomposition temperature and stepwise chemical decomposition characteristics of this reagent can effectively avoid the reduction of metals and improve sulfur adsorption to meet the needs for sulfidizing the hydrofining catalyst, and is a good reagent worthy of extended application.
