Research On The Distribution Of Oil And Water Layer Of K₂n⁴in Daqingzijing Region

Daqingzijing region belongs to the middle of southern Songliao basin area in the centraldepression zone of Changling sag, and with the further exploratory development of JilinOilfield carrying out, the region has become one of the major building blocks of capacity inrecent years.But because of the faulting developing and complex reservoir conditions,Heidimiao oil layer is non-essential reservoir, the conformational study, the reservoir studyand the comprehensive geological study are so less explored that they lead to the blurringunderstanding of reservoir and petroleum deposit, and they also affect evaluation anddevelopment deployment work. So in view of the exposed in the process of development inthe region of distribution of complex oil and water layer identification and difficult problem,we carried out distribution of oil-water of K2n4in Daqingzijing region. The study will focuson the geological characteristics of Daqingzijing region, under the premise of the study ofregional geology and reservoir characteristics in the research area, first of all, on the basis ofoil-water layer identification method, and use mud logging oil-water layer identificationtechnology for the assistance, to conduct oil-water layer identification, and established theoil-water layer identification plate. Then combined the well logging, mud logging, oil-waterlayer identification results and oil testing results and the regional structure, reservoirgeological characteristics, analyzed the distribution of oil-water layers of K2n4inDaqingzijing region. Through this study, we will provide the basis for implementation ofreserve scale evaluation of deployment and development wells. So as to lay a foundation tothe external expansion and build production of Daqingzijing oilfield.
