| Abstract | The rock fracturing technology can effectively enhance the reservoir permeability and conductivity of oil reservoir and improve the production of oil and gas. In this paper, high-current pulse discharge on rock fracturing was studied and a high voltage pulsed power supply was developed. The pulsed power supply is mainly composed of a high voltage high frequency charging supply, energy storage capacitors, a discharging electrodes and a safety discharging device. The maximum energy of the pulse power supply is 40kJ and working voltage is up to 20kV. The fracturing experiments are done on ten cement sandstones at low energy and high energy without confining pressure. Through the fracturing experiments of different samples, length and shape of the fracture have relations with pulse energy, the discharge voltage, discharge times and density of the rock. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
