苏里格地区苏X井区盒8段沉积相控储层测井解释分析

本文在对苏里格地区苏X井区石盒子组盒8段沉积相特征研究的基础之上,利用石盒子组盒8段GR、SP测并曲线特征,将研究区最发育的河道和心滩沉积储层分为箱形和钟形砂体两类,在此基础之上,分别作出了箱形和钟形砂体的声波时差-电阻率、密度-电阻率交会图,确定了研究区箱形和钟形砂体的气层、含气层、水层以及干层的界限值,并进一步的对建立的解释图版参数进行了应用效果分析。

The Well Logging Interpretation Analysis about the Sedimentary Facies Control Reservoir in He 8 Interval Su X Well Field of Sulige Area

On the basis of analysis of the sedimentary facies in He 8 interval, Shihezhi group, Su X well field, Sulige area, GR and SP well logs are used in He 8 interval.The most developed riverway and channel bar deposit reservoirs in the study area are divided into two types: box-shape sand body and bell-shape sand body.The acoustic differential time - resistivity and density - resistivity cross-plots are made for each. The threshold value for gas zone, gas-bearing zon, water zone and dry zone of these two types in this area are determined. The application effect is analysed through the parameters established by the interpretation chart.
