QHD32-6油田油井堵剂用量的确定
The Dosage of Plugging Agent in QHD32-6 Oilfield Well
摘要
Abstract
The breakthrough pressure of several different artificial core-models was measured after injecting 4 kinds of plugging agents,respectively.Combining with the stratum parameter of QHD32-6 oilfield,a relationship curve between the gradient of breakthrough pressure and the permeability of stratum was described under different formulas,and a relationship curve between plugging radius and water shutoff rate was obtained.Basing on this curve three slugs were designed in order to plug water effectively with less plugging agent according to the distance from measurement point to the oil well,and a best dosage was obtained finally.关键词
