摘要
渤海S油田于2009—2011年期间成功实施了我国海上稠油油田的首次加密调整工作,加密调整井投产产能高于调整方案设计值,如何正确认识这种现象,对指导海上稠油油田综合调整方案的设计具有十分重要的意义。文中分析评价了S油田稠油高含水阶段调整井的影响因素,剖析了射开程度、生产压差、层间干扰以及井斜等因素对调整井产能评价的影响。研究成果对处于中高含水阶段的海上油田调整方案的设计具有一定的借鉴意义。
The first infilling adjustment of offshore heavy oil reservoir was successfully implemented in the period from 2009 to 2011 in Oilfield S of Bohai Bay. And the production capacity of infill well is higher than the forecast production of adjustment plan. How to realize this phenomenon is very important for instructing the design of comprehensive adjustment plan for offshore oilfield. Taking Oilfield S as an example, this paper analyzes the influence factors of infill well at high water cut stage in offshore heavy oil oilfield.We analyze the effee, t of perforating degree, producing pressure drop, interlayer interference and well deflection on the productivity evaluation of infill well. The study result can provide a reference for adjustment plan design at high water cut stage in offshore oilfield.
