Daleel碳氢化合物油田位于阿曼北部的第5合同区块。以天然能量开发该油田Shuaiba碳酸盐岩油藏长达10余年,最初是直井生产后来改为水平井生产。由于该油田地下能量的高耗竭及对其二次开发的需要,在研究了各种方案后,水平井注水成为最佳方案。为了评价水平井注水方案,选定油藏某些区域进行了一些试验并密切监测新老井的表现。由于试验很成功,Daleel油田进入了其两大生产区块水平井注水二次开发的历史新时期,以期获得最高的采收率。除此之外,利用从试验区获得的测试和水平井注水经验可以给Daleel油田其他区块和世界范围内的类似油田提供有价值的参考。
Daleel Hydrocarbon Oilfield is located in the 5th contract block north of Oman. The Shuaiba carbonate reservoir was developed with natural energy for more than 10 years, initially as vertical well production and later as horizontal well production. Due to the high depletion of underground energy and the need for its secondary development in the field, horizontal well injection is the best solution after studying various options. In order to evaluate horizontal well watering schemes, some tests were conducted in selected areas of the reservoir and the performance of old and new wells closely monitored. Due to the success of the trial, the Daleel field entered a new historical period of secondary development of horizontal well waterflooding in its two major production blocks in order to achieve the highest oil recovery. In addition, the use of tests from pilot zones and horizontal well water injection can provide valuable references to other blocks of the Daleel field and similar fields around the world.
