多井测井储层表征技术在八面河油田中的应用

多井测井储层表征技术是将储层地质学与测井技术相结合的一门新兴技术,具有多信息、完整表征储层三维地质特征的优点。通过对八面河油田GB8-X2断块油藏不同井别测井资料的标准化,依据取芯井资料建立了储层测井解释模型。在此基础上,研究储层岩性、物性的平面变化特征,并编制高精度的构造图,进而识别出低阻油层。以此为指导,可以在细分储层单元的基础上对储层流体进行动态预测,达到寻找剩余油的目的。应用此项技术在济阳坳陷东营凹陷八面河油田识别低阻油层、寻找剩余油富集区取得了成功,累计新增探明储量248×10⁴t,增加可采储量50×10⁴t.

RESERVOIR CHARACTERIZATION TECHNIQUE WITH MULTI WELL LOG USED IN BAMIANHE OILFIELD

Multi well log reservoir characterization technique is a new technique which combines reservoir geology with well log.The technique is characterized by plenty of information and complete characterization of the reservoir's 3-D geological property.On the basis of the reservoir interpretation model which was established by log data standardization of different well types and core analysis in GB8-X2 block reservoir of Bamianhe Oilfield,the plane variation characters of lithology and petrophysics were studied and high resolution structural map was made,and then low-resistivity pays was identified.According to these,the dynamic prediction of reservoir flow was made by subdividing reservoir units and resedual oil enrichment could be found. This technique is used to search for residual oil enrichment zones,the result is successful.The totalized newly proved reserves are 248?10
