摘要: 雅克拉凝析气田位于新疆库车县境内,是中国石化最大整装砂岩凝析气藏。随着气田衰竭式开发,单井含水上升快,产能下降快,控水治水难度大,气井水淹停喷严重。由于新技术引进有限,措施增产过度依赖气井补孔改层和卡堵水,因此措施空间逐年下降,措施挖潜难度逐年增加。雅克拉采气厂通过精细化调整、气田精细开发、低压流程建设和一体化排液试验等一系列稳产增产措施,取得了不错的效果,为继续高效挖潜雅克拉气田的油气潜力,弥补老井的产量递减,维持气田稳产打开了思路,拓展了增产新方向。Abstract: Locating in Kuqa of Xinjiang, the Yakela Condensate Gas Field is one of the biggest equipped sandstone condensate gas reservoirs of SINOPEC. During depletion development, water content in a single well increases rapidly, and gas producing capacity decreases quickly. Water control has become difficult, and some wells stop flowing due to water flooding. Due to the limited introduction of new technology, the solution to increase production strongly depends on gas well patching holes, converting zone and water plugging, which show poor effects. Through fine adjustment, fine development of gas field, low pressure process construction, integrated liquid emission experi-ment and other actions to stabilize or increase production, the Yakela Gas Production Plant has reached good effects. A new direction is expanded to efficiently exploit oil and gas capacity of the Yakela Condensate Gas Field, which offsets the progressively decreasing production of old wells and stabilizes gas field production.
