宋芳屯地区葡萄花油层解释评价方法研究

The interpretation and evaluation methods for Putaohua reservoir in Songfangtun area

宋芳屯地区葡萄花油层储集层物性较差,水动力活跃、油水关系复杂,录井解释评价难度较大,解释判准率不高。针对该地区特点开展研究,分别建立了4种录井单项技术解释标准及解释图板,通过应用多项单种技术及资料分析,形成了适合宋芳屯地区葡萄花油层特点的油水层综合定量解释评价方法,并在生产应用中取得了较好效果,综合解释判准率达到89.5%,比原来提高了9.7%。

The physical properties of Putaohua reservoir in Songfangtun area is poorer with active hydrodynamic force and complex water and oil relationship,which has resulted in being very difficult for mud logging interpretation and the low efficiency of interpretation discrimination. The research has been carried out according to the features of the area,and set up 4 kinds of single mud logging technical interpretation standards and charts. By applying the multi single technologies and analyzing the data,the quantitative interpretation and evaluation method was produced,which is suitable for the features of Putaohua reservoir in Songfangtun area,and the better result has been obtained in the application. The composite accuracy of interpretation discrimination reached to 89.5%,which was 9.7% higher than the original.
