Research On Reservoir Evaluation And Fracturing Technology Of Single Sandbody On East Xing 6 Block

In Xing 6 region Da Qing Oil Field, the reservoir physical property and the development of single sand body is very different, the thickness of many layers are very thin. For the above-mentioned reasons, the surplus oils are hard to exploit. The fracturing technology of single sand body is based on fine geology research results, the research object are well groups, thinking about the differences of reservoir layers and the distribution condition of surplus oils. On the horizontal it fractures the single sand body, on the vertical it fractures many layers. Ultimately, the condition of water injection and oil production is well improved.In order to explore technical way of effective development of hard recovered reservoir in Xing 6 Block, and to solve problems in oilfield development. In this paper, based on the investigation of low permeability reservoir development at home and abroad, combined with geologic description of Xing 6 Block in past, apllied in the thery of petrolem geology, system analysis and research of reservoir and petrography character, reservoir parameter and fractures are completed.This topic is based on the geologic research in Xing 6 region, making the evaluation and analysis of water flow potential field and actual test results. It confirms the method to choose the fracture object, the morphology and parameters of fracture are clear and definite, and it forms the optimum design method of the corresponding fracture. The fracturing technology of single sand body will be the valid way to the exploition of surplus oils in Xing 6 region.
