【摘要】 海外河油田d1Ⅰ亚段为区域抬升背景下形成的一套砂砾岩稠油油藏,目前仅在主体部位新海27块上报了672×104t储量。通过烃源岩、油气运移通道、生储盖配置条件等成藏因素分析,结合"三老"资料复查,证实了d1Ⅰ亚段存在扩边潜力。综合运用地震精细解释重新落实构造、测井二次解释重新划定油层判别标准、选择典型井试采等方法,在新海27块周边实现扩边增储210×104t,部署的滚动扩边井实现预期效果。更多还原

【Abstract】 D1Ⅰ sub-member of Haiwaihe oilfield is sand-gravel heavy oil reservoir that formed under regional uplifting background,it is only reported reserve 6.72 million ton in the principal portion that is XH27 block.Through the research of hydrocarbon accumulation factors that include source rock,hydrocarbon migration channel and favorable conditions for oil and gas forming,reserving and covering.And combined with the reexamination of "three kinds of the old existed data",it proved this area has expanding potential.It is using fine interpretation to reworkable structure formation,secondary log interpretation to divide to identification standards for corresponding reservoirs which increased reserves to 2.1 million ton,and rolling and expanding well realized the predicted effect.更多还原
