CO_2吞吐增产机理室内研究与应用

STUDY AND APPLICATION OF THE STIMULATION MECHANISM OF CO_2 HUFF AND PUFF

文中对二氧化碳吞吐的增产机理进行室内研究 ,确定了二氧化碳吞吐的适用范围 ,制定了选井条件。在一些复杂小断块油田上应用二氧化碳进行单井吞吐 ,取得了很好的增产效果。

In this paper,We study the stimulation mechanism of CO 2 huff and puff,make sure the suitability of CO 2 huff and puff and the conditions of selecting wells.Through application of CO 2 huff and puff in some small fault block oilfields,good stimulation effects are got.
