PCO低渗透砂岩油藏裂缝特征综合描述
COMPREHENSIVE DESCRIPTION OF THE FAULT CHARACTERISTICS FOR PCO LOW-PERMEABILITY SANDSTONE OIL RESERVOIRS
摘要
Abstract
Oil Reservoir VOA1 of Argentina PCO Oilfield is the sand-shale interbedded sandstone reservoirs with the moderate pores and ultra-low permeability,the trap of the oil reservoirs is a single large-scale fault-nose.With the help of the following comprehensive analyses including the core data,structural evolution,seismic curvature and ant tracking attributes,abnormal response data of the high water cut occurred during the initial production in the partial wells of the net oil blocks of the structural highs of the oil reservoirs,the combined characterization shows from the viewpoints including the visual features of the cores of the structural fracture,structural stress,spatial distribution scope and configurations,dynamic opening mechanism and so on.The study achievements show that integrated with the geological,seismic,production data and so forth,the fracture characteristics and their correlations are described from the above many viewpoints,the reliability is so high that can reduce the uncertainty of the fracture characterization by individual method to a great deal,thus the effective insurance and guarantee are presented for the adjustment of the production program.关键词
