【摘要】：在油藏地质研究方面,能够较为准确地进行油、水层识别一直以来都是一个非常值得关注的问题。彭滩-新安边地区长6组属于低孔特低渗储层,当前开采产水量高、采出程度低,测井解释符合率偏低,开展研究区测井二次精细解释研究工作,重新确定油水层解释标准,确定有效厚度,对指导油田开发生产具有重要意义。本文以彭滩-新安边地区长61小层为例,首先进行测井系列优化,通过图示法和相关对比法进行岩心深度归位。由测井数据和试油资料分析发现研究区存在低阻油层,并研究低阻成因,故而将工区划分为南北两区。然后研究“四性”关系,建立两个区块储层孔、渗、饱和泥质含量参数计算模型。最后采用交会图技术分别确定南北两区油层电性解释标准,进而建立了一套适合两分区的测井解释模型。分析油井试油结论与二次解释结果表明,建立的该套测井二次解释模型能够较准确地识别油、水层,确定有效厚度。
[Abstract]:In the aspect of reservoir geological research, can more accurately identify oil and water has always been a very important problem. Peng Tan - Xin'an border region 6 low Kong Te group belongs to low permeability reservoir, the exploitation of high water yield, low recovery degree, the coincidence rate of logging interpretation is low, carry out research two log fine interpretation of research work, to determine the oil layer interpretation standard, determine the effective thickness, is of great significance to guide the development and production of oil. In this paper, Peng Tan - Xin'an border region 61 layer as an example, the first log series optimization, core depth homing by graphic method and the correlation method by logging. The data and testing data analysis shows that there are low resistivity reservoir in the study area, and study the genesis of low resistivity, so the area is divided into North and south two areas. Then study the correlation of four, two building blocks of reservoir pore permeability, saturation, clay content The parameter calculation model. Finally, the crossplot technique identified two areas of the north and South oil electric interpretation standard and interpretation model is established for a two partition analysis of oil well logging. Test results and the two interpretation results show that the establishment of the two set of logging interpretation model can accurately identify the oil, water, determination effective thickness.
