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GB8X2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。
Multi-well logging reservoir characterization technology is an emerging technology combining reservoir geology with well logging technology. It has the advantages of multi-information and complete characterization of reservoir three-dimensional geological features. Based on the standardization of logging data of different wells in GB8X2 fault block reservoir in Bamianhe Oilfield, a well logging interpretation model was established based on the data of coring wells. Based on this, the lithology and physical properties of the reservoirs are studied and the high-resolution tectonic maps are compiled to identify low-resistivity reservoirs. Using this as a guide, the reservoir fluid can be dynamically predicted on the basis of subdividing reservoir units to achieve the purpose of finding the remaining oil. Applying this technology to the Bamianhe Oilfield in Dongying Depression, Jiyang Depression identifies low resistivity reservoirs and succeeds in searching for remaining oil enrichment areas. The cumulative proved reserves are 248 × 104t and recoverable reserves are increased by 50 × 104t.
