垦利油田是一典型的多断块油藏,断层对该区的油水分布有很强的控制作用。在构造研究的基础上,利用三维地震解释资料,通过精细储层研究,对该区构造格架进行了重新解释,深化了对注水开发起遮挡作用的断裂体系的认识,大幅度提高了构造格架模型的精度。并且从两盘接触关系,两盘产出及压力变化情况、井间注入与产出、产同与产出的干扰状况判断断层的封堵性,对剩余油研究及下步挖潜提供了较为可靠的依据。
Kenli oilfield is a typical multi-fault block reservoir in which
the faults control the distribution of the oil and water. This paper
conducts an in-depth study of the structure of this oilfield by
reinterpreting the three-dimensional seismic data ,hence achieving
a better understanding of the faults system and considerably
improving the preciseness of the trellis structure model.
Moreover ,this paper attempts to judge the blocking effect of the
faults by examining the joint patterns of two trays ,the relationship
between the output and the pressure of the trays ,the relationship
between water injection and oil output of two wells , and the
interference of the output of one well with that of another. In this
way ,this paper provides a reliable basis for the study and further
exploitation of the remaining oil reserves.
