欢东油田压裂工艺应用及效果分析

Application and Its Result Analysis for Fracture Technology in H uandong Oilfield.

针对辽河油田欢东地区低渗透油藏不同的油层情况 ,采用了分层压裂 ,投球选压 ,热压裂液压裂 ,复合支撑压裂 ,大排量、大砂量压裂及控缝高压裂多种不同的压裂工艺 ,取得了较好的压裂效果 ,改善了该地区油气层的渗透性 ,促进了油田的长期稳产。文中还分析了影响压裂效果的各种因素 ,对其它地区的压裂施工具有借鉴作用。

In accordance with the different oil layer' features of low perme ab ility reservoir in Huandong area of Liaohe oilfield,many kinds of fracture techn ology,such as separate layer fracturing,ball fracturing,heat fracture fluid,comb ined support fracturing,high duty and high sand fracture,have been adopted.Th at achieved a good results,improved the hydrocarbon reservoir' permeability and pr omoted a long term stable production.The paper analyzes every factor which influ ences facture effect and provides a basis for fracturing operation in other area s.
