【摘要】 YA6井为一口边远单井气藏内的气井,产出气直供地方用户。由于三峡工程拦江大坝截流后,井场将低于水面23m。为此,研究是否有必要对原井口进行水下保护,以保证拦江大坝截流后继续维持该井稳定生产的态势。研究成果表明,目前生产井控制储量采出程度低,还剩余储量3.04×108m3,因此,对原井口进行水下保护,以保证拦江大坝截流后继续维持该井稳定的生产态势,制定合理的工作制度,提高YA6井控制储量的采收率,是非常必要的。更多还原

【Abstract】 Well YA 6 is a gas well in an outlying single-well gas reservoir, which produces directly for local users. If the damming of the Three Gorges Project is completed, the well site should be 23 m below the water level. So, it′s necessary to have a underground protection of original wellhead to keep a stable production. Result indicates that the producing well has a low productivity for probable reserves, whereas remaining 3.04×108m3. Therefore, it′s necessary to work out a reasonable working system to increase the recovery ratio of probable reserves.更多还原
