东辛油田低电阻率油气层测井解释评价技术研究
|
摘要
东辛油田由于受构造、沉积、成岩等多因素的影响,形成了以油层电阻率变化大为主要特点的碎屑岩复杂油气层,其中包括与水层电阻率较接近的低电阻油层。本文着重研究了东辛油田低电阻率油气层成因、定性、定量解释方法以及应用效果分析。
以岩心分析资料为基础,结合有限的核磁等新方法测井资料,搞清了东辛油田低电阻油气层的成因和类型,主要有以下四种类型:一:高矿化度地层水的影响;二:孔隙结构的影响;三:阳离子交换量的影响;四:泥浆侵入的影响。
本次研究中实行岩电实验与油层物理实验相结合,深入地研究电阻率高低变化与微观孔隙结构的关系、测井解释参数与孔隙结构的关系、核磁测井中的T2分布与孔隙结构之间的关系,通过岩心毛管压力资料和对应的核磁室内测量资料,分析建立了应用核磁测井资料确定储层微观孔隙结构参数的方法。
另外针对不同类型的低阻油层建立了相应的定性、定量解释方法,定性解释方法主要是通过建立交会图和解释图版进行定性判别,定量解释方法主要是建立了以核磁测井为基础的可变m、n解释方法、利用以常规测井为基础的可动水法评价储层性能,另外就是利用双组孔隙模型对含油饱和度进行校正等方法。
研究成果在东辛油田得到了明显的地质应用效果。为油田的勘探开发进程做出了积极的贡献。
The reservoir resistivity in different region varies larger because of the influence of the structure, deposition and digenesis in dongxin Oilfield. The distinguish feature of classic reservoir in dongxin Oilfield is the variety of resistivity including low resistivity reservoir. The complex reservoir had produced the commercial oil and gas flow and because the main production reservoir. This document concerted on the origin of low resistivity reservoir and qualitative or quantitative interpretation including analysis of application in dongxin Oil field.
Have investigated deeply the relation of resistivity and microscope pore structure, the relation of the parameter of log interpretation and pore structure, the relation of T2 destruction in NML and pore structure with capillary pressure of the half permeation barrier and lithology electronic experiment technology. Have built the method of determining microscopic pore structured parameter with the NML information.
Have built the different qualitative and quantitative interpretation technology of the low resistivity reservoir according to the different type. The qualitative interpretation based on cross plot and interpretation chart. Have built the method of interpretation of variable m, n based on NML, evaluated the reservoir prosperity of movable water-bearing .Correlate the value of the oil saturation with the model of dual group structure.
The research have got the evident geological application in dongxin Oil field.. And have mad the important contribution in exploration and development in this Oil field.
