低渗透裂缝型油田周期注水参数优化
PARAMETER OPTIMIZATION OF THE CYCLIC WATER FLOODING FOR THE LOW-PERMEABILITY FRACTURED OILFIELD
摘要
Abstract
In view of poor reservoir physical properties of low-permeability fractured Mao Z Oilfield in Daqing peripheral area,the partial well-developed fractured well blocks are characterized by the fracture water,poor matrix effects,interlayer & planar contradictions and so on,on the basis of the obtained much better development effects of the previous cyclic water flooding test,the optimization of the cyclic waterflooding parameters was conducted.With the help of the phase controlling method,the fine 3D geological and numerical models were established,thus the discontinuous water injection patterns,time and intensities were optimized,and moreover according to the results of the parameter optimization,the field test was carried out.The obvious water-control and oil-increment effects have achieved for the test well block,more than 1.2 percentage recovery factor is expected,thus the study achievements have provided the technical means for the economically effective development of low-permeability fractured oil reservoirs.关键词
