海上稠油油田投产初期产能评价研究
|
摘要
近年来渤海海域新投产的几个稠油油田,初期产能与整体开发方案(ODP)设计值有一定的差距,如何合理确定油气井的产能,经济有效地开发好海上油田,已迫在眉睫。文中以海上某稠油油田为例,通过对油田投产初期产能再评价,对比投产初期与ODP阶段产能的差异,剖析了储层物性、流体性质、生产压差、表皮系数、层间干扰及DST测试时间等因素对产能评价的影响,研究成果对在建设的油田产能评价具有一定的借鉴意义。
In recent years,the deliverability of a few oilfields putting into production in Bohai Sea has been less than that of ODP designed value at initial stage of production.It is imminent to decide deliverability reasonably and develop offshore oilfield economically.Taking one heavy oilfield as an example and through deliverability evaluation of the oilfield at initial stage of production,this paper analyzes the influence factors on deliverability evaluation,such as reservoir physical property,liquid property, producing pressure drop,skin factor,interlayer interference and DST test time.The study results can provide certain references for deliverability evaluation.
