油井气举找水测井技术及其在中原油区的应用

针对产能较低、不能自喷且无偏心井口的抽油机井录取动态资料的需要,研究了一种新的测井方法,即油井气举找水测井技术。该方法利用压风车向井内加压气举,模拟地层生产状态,并根据不同井况优选测井系列,录取井下动态资料。该技术在中原油区应用35井次,测井成功率达100％,采取增产措施23井次,累积增油6558.8t,取得了明显的应用效果。

Logging technology of water detection by gas lift in oil wells and its application in Zhongyuan petroliferous province

new method of logging technique of water detection by gas lift is studied which is aimed at getting dynamic information in oil wells with low productivity, non-flowing and non-decentralized wellhead. This method uses air compressor to add air pressure and to make gas lift, simulates the producing state of pay zones, optimizes logging series and records dynamic subsurface information according to the various situations of oil wells. It was applied for 35 well times in Zhongyuan petroliferous province gaining 100% success ratio. Stimulation was taken for 23 well times, with 6558. 8 t of cumula tive incremental oil production . Obvious effect was achieved.
