摘要

渤海油田潜山储层岩性多样、地质条件复杂、非均质性强,传统机械比能模型对潜山储层储集性能响应的敏感性较差,难以高效指导勘探作业决策。为此,基于微钻头钻进实验和滑动窗口理论,分析了机械比能对工程参数的响应规律,构建了机械比能标准化模型和改进型机械比能模型,形成了潜山储层储集性能解释标准。结果表明:渤海油田潜山储层钻压系数为0.309～0.605;改进型机械比能小于0.80时为Ⅰ、Ⅱ类储层,改进型机械比能为0.80～1.15时为Ⅲ类储层,改进型机械比能大于1.15时为致密储层。研究成果在渤海油田36口潜山探井作业中进行了应用,储层储集性能解释符合率平均值为80.2%。该研究可为中途测试、完钻等勘探作业决策提供技术支持,具有很好的借鉴意义。

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 performance 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 parameters,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 specific 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 support for exploration decisions such as midterm testing and completion drilling, and has significant reference value.

Key words： mechanical specific energy model; reservoir performance; moving window principle; buried hill reservoir; Bohai Sea
