摘要
高升油田高3块是典型的中深层巨厚块状气顶底水稠油油藏,历经20余年的蒸汽吞吐开采,目前处于低压、低产、低效益的蒸汽吞吐后期采油阶段,呈现地层压力低、蒸汽吞吐效果差、油层严重脱气、油品性质变差等开发特征。针对稠油油田蒸汽吞吐后期生产特点,研究并实施了一系列行之有效的解决办法,取得了明显的成效。
Block Gao 3 in Gaosheng oilfield is a typical medium deep massive heavy oil reservoir with gas top and bottom water. It has been recovered by cyclic steam stimulation for more than 20 years, and is in late stage of cyclic steam stimulation now, showing low formation pressure, poor recovery effect, severe reservoir degasification, and downgraded oils. In accordance with these problems, a series of effective measures has been researched and implemented, and has achieved good result.
