概述通过对90口用油管输送射孔枪射孔情况的系统研究,揭示了要得到清洁射孔孔道所需的负压与地层渗透率的关系。这些资料是砂岩产油、气的井,经射孔、测试、酸化、再测试过程测得的。有一条清楚的最小负压线把那些具有清洁射孔孔道井(不需酸化帮助)的数据点与那些经酸化后明显增产井的数据点分开。本研究的资料选自墨西哥湾,路易斯安娜(塔斯卡卢萨走向)、新墨西哥(Morrow)(Morrow 砂岩)、落基山逆掩断层和加拿大的艾伯塔。 Overview The systematic study of the perforation of 90-port guns through perforating guns reveals the relationship between the negative pressure required to clean the perforation channels and formation permeability. These data are measured by sand production, gas wells, perforation, test, acidification, and retesting. A clear minimum vacuum line separates those data points that have clean perforation wells (without the aid of acidification) from those that have been significantly acidified. The data for this study were selected from the Gulf of Mexico, Louisiana (Tuscaloosa Walk), Morrow (Morrow Sandstone), the Rocky Mountain Upset and Alberta, Canada.
