提高水平井单井产能技术研究

Compound plugging acidizing technology research and application

长庆油田采油三厂水平井由于受储层物性等因素影响,投产后递减较大,单井产量低,为提高水平井单井产量、攻克低渗透油藏开发难度由于天然裂缝、人工裂缝以及非均质性等因素,开展了提高水平井单井产量技术研究,以水平井重复压裂、水平井酸化、水平井找水救赎为主攻方向,取得了初步效果。

Changqing oilfield three plant level due to the reservoir and other factors,production decline is larger, single well production is low, in order to improve the output of single well, horizontal well to the development of low permeability reservoir is difficult because of natural fracture, fracture and heterogeneity and other factors,to carry out research on improving the production technology of single well water hirai,the horizontal well fracturing,horizontal wells, horizontal wells for water saving as the main direction, obtained initial effect.
