| Abstract | The quality of the Ordovician carbonate reservoir beds in the Tarim Basin is closely related to the development of secondary pores, fractures and cavities. Karstification is important in improving the properties of reservoir beds, and karstification related to unconformity has caught wide attention. Compared with the recent research on the unconformity karst reservoir bed improvement, this paper shows a new way of carbonate reservoir bed transformation. Based on field survey, core and slices observation, transformation of Ordovician carbonate reservoir beds by faulting can be classified into three types: (1) Secondary faults and fracturs generated by faulting improved carbonate reservoir bed properties, which were named the Lunnan or Tazhong82 model; (2) upflow of deep geothermal fluids caused by faulting, with some components metasomatizing with carbonate and forming some secondary deposit, such as fluorite. It can improve carbonate reservoir bed properties obviously and is named the Tazhong 82 model; and (3) the faulting extending up to the surface increased the depth of supergene karstification and the thickness of reservoir bed. It is named the Hetianhe model. Transformation effect of carbonate reservoir beds by faulting was very significant, mainly distributed on the slopes or on the edge or plunging end of the uplift. |

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.
