An empirical investigation of competency factors affecting e-business success in European SMEs

In the last decade there was growing interest in strategic management literature about factors that influence a company's ability to use IT. There is general consensus that knowledge and competency are necessary in developing an IT capability, but there is very little understanding of what the necessary competencies are, and how they influence IS usage in different contexts. The small and medium-sized enterprise context is particularly interesting for two reasons: it constitutes a major part of the economy and it has been relatively unsuccessful in exploiting e-business.     

油井细粉砂防砂工艺技术研究与应用

辽河油田的油井出细粉砂严重，通过防砂基础理论及试验研究，形成了地层深部防砂与携排砂采油技术。在出细粉砂油井及出砂区块进行试验、应用，年平均采取防砂措施300余井次，防砂成功率达90％以上。     

中国第一口超千米深水钻井液技术

LW3-1-1探井位于中国南海珠江口盆地，作业水深1480m，完钻井深为3843m，地层以大套灰色泥岩和页岩为主，具有强水敏性．要求钻井液具有良好的流变性、润滑性、抑制性，良好的抗盐、抗钙、抗高温和抗低温能力，以及强的天然气水合物抑制能力。该井采用了PFMX钻井液体系，钻井周期为49d，介绍了钻井液工艺及现场应用情况。PFMX体系表现出很多油基钻井液的优点，如好的润滑性、高的钻进速率、膜效应、强的井眼稳定及页岩抑制性，解决了强水敏性地层的井壁稳定等问题，还解决了深水钻井中遇到的挑战，如低的破裂压力梯度、天然气永合物、浅层水流、深水低温等问题，满足了该区块作业需要。

Integrated distributed intelligent system for process-control system design

In process-control system design, the Computer Aided Design (CAD) techniques have evolved a new generation of design techniques. This also paves the way for implementing Computer Integrated Manufacturing Systems (CIMS). However, the key issue to accomplishing the objectives in CAD is the automation of conceptual design. This paper first introduces the fundamentals of conceptual design for process-control system design. Then, a strategy to solve the problems in conceptual design is proposed. The associated system configuration and software implementation platform for developing intelligent systems for process control system design are presented. Finally, an application case is studied.
