1) Driving and replacement of water and gas among coal seam
水-气驱替
2) water–drive-gas
水气驱替
1.
To study the fluid flow among coal in the course of water–drive-gas water injection in theory, when water injection is carried out, according to the fact that coal is double porous medium, when water injection is carried out, according to the fact that coal is double porous medium, the differential equations set of water plane radical flow are discussed according to two kinds of condition.
在此条件下,考虑到煤层孔隙喉径,隙间无流体流动,仍为单一裂隙渗流,其水气驱替与单纯孔隙水气驱替相近,渗流为稳定流时情况也与此相同。
3) gas-alternating-water flooding
气水交替驱
1.
Injectivity reduction is an important factor to restrict recovery increase by gas-alternating-water flooding.
针对注入能力降低是制约气水交替驱提高油藏采收率的关键因素的问题,以相似理论中的检验分析法推导了气水交替注入无因次注入能力方程,运用考虑相渗和毛管滞后效应耦合的数值模拟方法,评价无因次注入能力的因素影响,讨论并优化了注入水气比。
