在测试管柱中使用OMNI循环阀值得注意的几个问题

Some Problems to Be Noted for Using OMNI Reverse Circulating Valve in Well Testing String.

OMNI循环阀是一种通过环空压力操作,可多次开关的循环阀,该阀操作简单,只需周期性的环空加压、放压即可完成操作。结合在印尼测试服务中多口井几十层的现场应用,从OMNI阀的操作、保养维护等几个方面剖析了OMNI循环阀在使用过程中出现的一些常见问题,结合现场经验,提出了相应的解决或预防措施。

OMNI reverse circulating valve is a kind of valves to be operated by annulus pressure and closed or opened many times which is simple operated and completed only by periodical making or leasing annulus pressure. Combined field applications of it servicing at Indonesia in tens layers of many wells,some popular problems during usage of OMNI valve from its operation and maintenance are analyzed. According to field experiences, the paper suggests some correspond solving or preventing measures.
