Advantaged Flow Field Identification and Adjustment in High Water Cut Stage
摘要
Abstract
To accurately identify the advantaged flow filed between oil &injection well and determine the oil & injection well pairs in advantaged flow filed is of great significance for the method of water controlling and oil increasing in reservoir at high water cut period. In response to this problem, we take Daqing oilfield as an example to research the advantaged flow channel distribution between oil well and injection well and to determine oil and injection well pairs with advantaged flow field in high water cut by the correlation coefficient method between oil wells and injection wells and reservoir sedimentary facies and flow tube numerical simulation method. And the advantaged flow field is graded through the new method of daily water injection and oil wells water cut probability distribution. And fine adjustment measures are developed to tap residual oil in high water cut according to the identified flow field distribution. After adjustment, the overall water cut is reduced from 96. 7%to 95. 1%and daily oil increase is stabilized at 43. 5 t.关键词
