| 摘 要： | 水平井酸化伤害机理与垂直井有明显的差异。基于钻井液的侵入特征和水平井渗流机理,分析了水平井的伤害特征;采用理论模型计算不同井段钻井液的等效污染深度,通过体积变化得出不同井段处的污染带半径;结合砂岩基质酸化模型,有效计算水平井酸化酸液用量。为水平井酸化增产提供了优化设计,具有良好的经济效应。

| Abstract: | The acidizing damage mechanism of horizontal well is quite different to that of vertical one.Based on the invasion property of drilling fluid and seepage mechanism of horizontal well,this paper analyzes the damage characteristics,adopts theoretical model to calculate the equivalent pollution depth of drilling fluid in different sections,and obtains the pollution radius by volume changes.Moreover,combined with acidizing model of sandstone matrix,the acid dosage for horizontal well is calculated.It provides a... |
