塔河七区溶洞储集体发育特征及物性建模
|
摘要
为解决塔河七区T607单元井资料较少、溶洞储集体内部物性参数分布规律不明的问题,提出了以充填模式为指导的概率函数约束建模方法。在溶洞储集体识别的基础上,分析其充填物特征,总结充填模式,并以此为指导构建概率函数,从而约束孔隙度建模过程。研究结果表明,T607单元共发育地下河型溶洞及孤立型溶洞两类储集体,前者在平面上延伸较长,而后者则在垂向上分布较广;地下河型溶洞主要发育搬运型砾岩、搬运型砂岩等充填物,孔隙度曲线垂向呈现"叠置漏斗型",孤立型溶洞主要发育混杂角砾岩充填物,孔隙度曲线垂向上呈现粗略"箱型";结合建模结果,认为控制洞穴储集体的关键参数为其充填特征及规模。
In order to make clear the property parameters distribution of the cavity reservoirs in Tahe Block 7 with less well data,the combined method of property modeling controlled by possibility distribution function based on cavity filling mode is proposed. On basis of cavity recognition,the characteristics of cavity filling and filling mode were analyzed,and the possibility distribution function was thus built,which was used in controlling the property modeling process. It is concluded that 2 types of cavity reservoir develop in T607 unit,including underground-river-cavity and isolated-cavity,the former mainly extends horizontally,and the latter vertically. The fillings in underground-river-cavity are mainly transported conglomerate and sandstones,and its porosity log is"superposed funnel"shaped; the fillings in isolated-cavity are mainly collapse breccia,and its porosity log is roughly "box"shaped. According to the porosity model,the controlling factors of the cavity reservoirs are their filling mode and sizes.
