Process management of project is macroscopically divided into fine management of “person” and “affairs”. In the management area of “person”, the people involved in management process of project are divided into different roles so that they perform the different functions of process managementaccording totheirroles. Inthemanagement areaof “affairs”,theworkflow technology is used to establish astandard fine process for management of project process. Based on those efforts, information technology is adopted to develop the information platform for fine management of technological projects, bringing about effective integration of Project Desk Software andWeb System. The project team can share files and communicate information on this platform. Executives of all levels can inspect the progress of project on this platform and dynamic follow up and analyze technological projects, bringing the process of technological projects under a fine, automatic and standard management. The application results indicate that this platform can remarkably improve the information level for management of technological projects. To promote application of this platform, the article suggests to perfect the project management system with the efforts for development of appraisal methods, summarize and exchange experiences within the organizational system, strengthen the efforts for information training, and enhance technological support system.

Present Conditions and Prospect of Shale Gas Development Liu Cunzhong 2013, 32(3): 32-37, 67.  DOI: 10.3969/j.issn.1002-302x.2013.03.008 Abstract ( )   PDF (7499KB) ( )   Development and utilization of non-conventional oil and gas resources has drawn great attention owing to the continuous demand of energy by the human society and increasingly high consumption of primary fossil energy. Shale gas development and utilization has been an example in recent years. The United States is one of the best countries in the world for shale gas production and utilization. The US shale gas production reached 1800×108m3 in 2011, triggering the so-called “shale gas revolution”. However, so far as global shale gas development is concerned, the US pattern may not be suitable in some other regions, because shale gas development is restricted by a number of factors, such as technological adaptability, the environment, infrastructure and supporting systems, investment fund and market mechanism. It is still early for shale gas to act as the stand-by resources for conventional oil and gas resources. China is quite different from the United States in terms of the national conditions and infrastructure including auxiliary systems. The US pattern for non-conventional natural gasdevelopment cannot be entirely duplicatedin China.It is necessary tomakea unifiedplan accordingto the Chinese conditions and work out a set of methods for development and utilization of non-conventional natural gas that is feasible in China.

Different from conventional steerable screw drill, the bent angle of the bent shell of universal coupling can be freely adjusted without dismantling the drill tool. The bent angle is usually adjusted within a scope of 0-3°. The near-bit stabilizer can be freely replaced without dismantling the drill tool. The size of stabilizer is usually 3.175-12.7mm less than the size of hole. The structural and engineering parameters of steerable screw drill can be adjusted in real time on the drilling operational site according to the concrete working conditions, thus improving the flexibility of service tool and controllability of operational process. This help improve drilling engineering quality and lower drilling cost. This article also proposes to continue optimization design in order to solve the problems related to the existing adjustable bent shell and on-site change of replaceable stabilizer.
