From 2009 to 2012, China completed an accumulative number of 129 drilling wells related to shale gas, including 46 investigated vertical wells, 55 exploration wells and 28 evaluation wells, with 2012 production ranging from 25 million cubic meters (mcm) to 30 mcm.展开更多

In order to shrink the gap between the coastal 'million' cities and the interior 'million' cities, the paper thinks that the central government should pay most attention to the economic development of the inland, meanwhile,the interior 'mllion' cities should speed up the economic reform and industrial restructuring.展开更多

We then present key technologies of the simulator, such as nonlinear and linear solvers, communications among processors, parallel I/O, etc., and corresponding content. Finally, some results of the platform to solve one million grid blocks cases from Chinese oil fields are given in the paper, which can show that the simulator has a very robust portability, high-speed for deadline and good scalability for the tested cases. As one of the application softwares, its objective is always focusing on satisfying deadlines of oil industry. Now, for one million grid blocks' case with 20 - 30 year-production, its elapsed time with 16 processors is less than 12 hours on parallel computers based on Myrinet or QsNet, namely 'to submit a case just before off-duty and get its result just before on-duty'. A decreasing line of elapsed time is given for a case with one million grid blocks. The developing trace of the simulator along with parallel computers can be also inferred from the line.展开更多

This workflow is a process consisting of multiple phases, namely, scanning, image processing, OCR, digital archiving, document encoding, and publishing. Over the past couple of years, the BA has defined procedures and special techniques for the scanning, processing, OCR and publishing, especially of Arabic books. This workflow has been automated, allowing the governance of the different phases and making possible the production of 18000 books so far. The BA has also designed and implemented a framework for the encoding of digital books that allows publishing as well as a software system for managing the creation, maintenance, and publishing of the overall digital repository.展开更多
