Water cut rising rules and water control countermeasures of reservoir of Xishanyao Formation in Niuquanhu block
Online published: 2014-10-20
Too rapid rising of water cut in Niuquanhu block has seriously restricted the stable oil production. Based on relative permeability curves, model prediction, plate method, water drive curve method, this paper studied water cut rising rule, obtained the recovery of each block changes with water cut and the water cut forecasting model, and
compared with the actual water cut rising, finally optimized suitable method for the prediction of water cut in each block. The water cut rising rule of single well was analyzed. According to water cut change characteristics, we divided water cut rising into 5 types, analyzed the development features and formation mechanism of each type of water cur rising, and proposed corresponding technical countermeasures, which provides references for the effective development in Niuquanhu block.
