Abstract:

The reservoir in LZ area is tight sandstone reservoir, and fractures control the reservoir spaces and well capacity. Based on the analysis of structural features and evolution, combined with the fracture divided period coordination on the basis of outcrop data, the tectonic origin of fractures is analyzed. It is considered that the fractures developed in the study area mainly are shear fracture, tensional fracture, associated and derived fractures with faults. The constructional curvature method, paleotectonic stress field finite element modeling method and seismic discontinuity detection method are applied to predict the different fractures respectively. The weight is adopted to evaluate the prediction results. It is to establish the regression function between the accuracy of the prediction method and its influencing factors, and then define the weight coefficient through the prediction accuracy and calculate the weights of the different prediction results. Finally it can be used to predict the fracture development in tight sandstone reservoir in the study area. The well drilling data prove the good prediction effects.

Key words: grey system, weight coefficient, reservoir evaluation, Putaohua Oilfield, northern Songliao Basin
