阿里斯库姆大气顶薄油环边底水油田开发方式
|
摘要
阿里斯库姆油田是一个具大气顶、薄油环、边底水的复杂油气藏。通过调研国内外同类油气藏的开发方式,确定该油藏合理开发方式,采用气顶注气及屏障注水,避免气窜和水侵;采用水平井开发薄油环,北部和南部采用完善井网滚动扩边开发。实施后,气顶气窜得到了有效控制,油藏地层压力保持程度稳步回升,油田产量逐年增加。因此,所采用开发方式合理有效。
Aryskum oilfield is a complicated oil and gas reservoir with large gas cap, thin oil rim and edge/bottom water. To determine therational development method for this reservoir, based on extensive investigations of development methods for analogous reservoirs both athome and abroad, the author adopted the method of gas injection into the gas cap and barrier waterflooding to avoid gas channeling and wa-ter encroachment. Horizontal well was adopted to develop the thin oil rims and the well patterns were perfected for progressive and exten-sional development in the south and north of the oilfield. After implementation, the gas channeling in the gas cap has been effectively con-trolled and the formation pressure has been maintained and kept rising steadily, while the oil production of the oilfield increased year byyear. Therefore, the method has been determined as the effective development method for such complicated oil and gas reservoirs.
