摘要(Abstract):
利川复向斜从志留系—三叠系具有7个生储盖组合。生油层有由下向上显著变差的趋势。据计算,志留系生烃量约占全区生烃总量的85%,因此勘探目的层主要为石炭系—二叠系。储层以复向斜中部南段、南部西翼的二叠系长兴组礁白云岩和三叠系嘉二段底部白云岩较好,石炭系、二叠系茅口组和三叠系大三段储层亦显示由东向西变好,故复向斜西翼即齐岳山构造带东侧地腹若有圈闭存在,应是本区获气最有希望的地区。
Composite study and theoretical
calculation of numerical simulation are conducted on the basis of ASP flooding pilot tests in
Xingwu Area, Xinger Area, Beiyiduanxi Area of Daqing Oilfield, and by combining physical
simulation experiment on heterogeneous cores. Principle of reasonable ASP flooding well
pattern and spacing in different areas are given under considering present well pattern in the
Northern part of Sazhong Area and Xingbei Area.
