机械比能模型在潜山储集层评价中的改进与应用
Improvement and Application of Mechanical Specific Energy Model in Buried Hill Reservoir Evaluation
摘要
Abstract
The buried hill reservoirs in the Bohai oilfield exhibit diverse lithology,complex geological conditions,and strong heterogeneity,making traditional mechanical specific energy models less sensitive to the reservoir's perform-ance and hard to provide efficient guide exploration strategy.Therefore,based on micro-bit drilling tests and the moving window theory,this study analyzed the response patterns of mechanical specific energy to engineering param-eters,constructed standardized mechanical specific energy models and modified mechanical specific energy models,also formulated interpretation standards for reservoir performance in buried hill reservoirs.The results indicate that the drilling pressure coefficient of buried hill reservoirs in Bohai oilfield ranges from 0.309 to 0.605.When the spe-cific energy of the modified mechanical model is less than 0.80,it corresponds to Type Ⅰ and Type Ⅱ reservoir;when the specific energy ranges from 0.80 to 1.15,it corresponds to Type Ⅲ reservoir,while when it exceeds 1.15,it is tight reservoir.The research findings have been applied in 36 buried exploration wells in Bohai oilfield,with anaverage interpretation coincidence rate of reservoir performance of 80.2％.This study can provide technical sup-port for exploration decisions such as midterm testing and completion drilling,and has significant reference value.关键词
