江汉油区水平井堵水技术适应性分析

Adaptability Analysis of Water Plugging Technology to Horizontal Wells of Jianghan Oildom

江汉油区自1999年以来,共投产水平井49口,其中有8口井先后14井次进行了卡堵水技术,包括12井次的机械堵水、2井次化学挤堵。为此,在对水平井的机械堵水效果进行分析的基础上,探索适合水平井的堵水方式。

Since 1999,forty-nine horizontal wells have been put into production in Jianghan oilfield,eight of which have gone through 14 well times of water plugging technology one after another,consisting of 12 well times of mechanical water shutoff and 2 of chemical squeeze.Therefore,the authors explore the water shutoff pattern adequate for horizontal wells on the basis of result analysis of their mechanical water shutoff.
