摘　　要：准噶尔盆地西部隆起中拐凸起二叠系佳木河组断块发育,各断块间油、气相态差异较大,各断块油、气、水关系复杂,普遍具有“一块一藏”的特征,造成流体识别困难;储层以安山质、凝灰质砂砾岩为主,储层具有低孔低渗特征,横向上储层非均质性强,储层的产能评价难度较大。为了快速落实中拐凸起**地区二叠系佳木河组储层流体性质以及纵向气、油、水分布规律,加快该区块的勘探评价开发的进程,新疆油田在**区块的***1井首次采用了新一代智能化地层测试平台的深层测试测井新技术,在二叠系佳木河组二段一砂组进行三段测试,确认了三层的流体性质,砂组中下部的测试为油层的第三层与试油结果完全吻合,在其之上的二层测试结果分别为油层和气层,说明三层测试结果直观、准确。因此,电缆测试新技术对于快速评价厚层规模储层段含油气性,深化**地区规模厚层砂砾岩油气藏认识、落实储量规模、节省试油费用等方面发挥了重要作用。In the western part of the uplift of Junggar Basin,the oil and gas phases are greatly,and the relationship between oil,gas and water is complex,which has the characteristics of"one piece and one reservoir",resulting in fluid identification;The reservoir is mainly Anshan and coagulaceous gravel,the reservoir has low hole and low permeability,the horizontal reservoir is highly heterogeneous,and the reservoir capacity evaluation is difficult.In order to quickly implement the turn raised in**area Permian better mu river reservoir fluid properties and longitudinal gas,oil,water distribution law,speed up the development process of the block,Xinjiang oilfield in**block***1 well first adopted a new generation of intelligent formation test platform deep test logging new technology,in the Permian jia wood river group two sand group of three sections,confirmed the three fluid properties,sand group in the lower layer of the third layer and oil test results,above the second layer and gas layer respectively,the three layer test results are intuitive and accurate.Therefore,the new cable test technology plays an important role in the rapid evaluation of oil and gas content in thick-scale reservoir section,deepening the understanding of large-scale thick sand and gravel rock reservoirs in**area,implementing the reserve scale and saving the cost of oil test.
