井温找水工艺在文留油田的应用

The Application of Water Detection Technology by Well Temperature in Wenliu Oilfield

注水油田进入中后期开发后，油井在生产初期的主力层逐渐成为高压水淹层，使其他低渗低压层无法被开发利用，因此必须找出出水层段，然后采取适当的堵水措施。文留油田采用自然伽马磁定位井温找水工艺进行了308井次的找水施工，并对146口井采取了堵水措施，取得显著效果。实践表明，该工艺具备操作简便、数据精确、费用低廉等特点。

During the middle and late stage of water flood field development, the major reservoirs in the eary stage are becoming high pressure and water flooded intervals, but the low permeable and pressre layers Can't be preduced. Thus, the water preducing intervals must be found, then the appropriate water shutoff processes can be used. From 1992 to 1998, 308 water detection programs have been made in Wenliu Oilfield using natural gamma magnetic orientation in well temperature,of which 146 wells have been plugged from water,and notable results have been received. The applied results in practice shows: the technology of water detection posses of the characteristics, such as simple operation, accurate data, low cost, having a wide application in water detection.
