【 摘 要 】

The main objectives of this work are to map and characterize network of likely fractures to develop major deposits carbonated in the region. It is a contribution to a better knowledge of the geometry of existing surface fractures networks and their extension in subsurface. For this it appeals to the tool of remote sensing and seismic. Using remote sensing data, our study enabled us to draw up a card lineament, along with tectonic analysis, where we could list 409 lineaments divided into 9 classes according to their directions, among which: the main directions of the NW/SE fracturing are: H (N1300-N1500), G (N1100-N1300) and F (N900-N1100). These three classes are in agreement with the major flaws of the region, which are: the fault of Biskra-Outaya, Ouinet-Morsott-Tébessa and the dextrose form. Of after the deferential work carried out on the South East Constantine area, and the results obtained by the seismic reflection, as well as the well data, summarizes our reservoirs are characterized by a mainly low to medium porosity and low permeability, these tanks are carbonated, and are affected by the majority of vulnerabilities detected on the surface, but these do not contribute to the improvement of the Petrophysical characteristics This can be reported to the clogging of the cracks.
