【摘要】：子长油田子115、子113井区主要开发层系为长2油层。本区油藏埋藏较浅,油井具有初产较高、递减较快的特点。为达到提高油田开发水平、提高采收率目的,就必须提高油藏描述水平,开展储层特征研究。本文在前人研究的基础上,开展了地层精细划分对比与构造特征、储层沉积相研究、地质约束的测井储层评价及二次处理和储层综合评价等基础研究工作。研究中利用了区域标志层K9和辅助标志层开展了精细地层划分和对比工作,建立的60条地层对比剖面,实现了全区地层对比的闭和与一致性。确定了研究区的油水层判别标准和物性下限标准,开展了测井资料二次处理,建立了研究区储层参数静态数据库。为子长油田下一步科学开发提供充分的理论依据。
[Abstract]:In Zichang Oilfield, Z115, Z113 well area is mainly developed by Chang 2 reservoir.The reservoir in this area is shallow buried, and the oil well has the characteristics of high initial production and fast decline.In order to improve the level of oilfield development and enhance oil recovery, it is necessary to improve the level of reservoir description and study reservoir characteristics.On the basis of previous studies, this paper has carried out the basic research work, such as fine stratigraphic division and correlation and structural characteristics, reservoir sedimentary facies, logging reservoir evaluation with geological constraints, secondary processing and reservoir comprehensive evaluation, etc.In the study, the fine stratigraphic division and correlation work were carried out by using regional marker layer K9 and auxiliary marker layer, and 60 stratigraphic correlation sections were established, which realized the closure and consistency of stratigraphic correlation in the whole area.The criteria of oil and water reservoir discrimination and the lower limit of physical properties are determined, the secondary processing of logging data is carried out, and the static database of reservoir parameters in the study area is established.It provides sufficient theoretical basis for the next scientific development of Zichang Oilfield.
