车西古潜山碳酸盐岩储层酸压改造技术

车西古潜山碳酸盐岩储层由于埋藏深、地层温度高、酸液滤失大、酸岩反应缓速困难等，给酸压材料及酸压施工带来诸多困难。文中在分析车西古潜山碳酸盐岩储层酸压改造技术难点的基础上，重点探讨了适宜于本地区储层特点的酸压改造工艺技术及实施效果，得到了一些规律性的认识，对类似特点的储层改造具有一定的指导作用。

ACID FRACTURING MODIFICATION TECHNIQUES OF CARBONATE RESERVOIR IN CHEXI BURIED HILL

Chexi buried hill carbonate reservoir has deep buried depth,high formation temperature,much acid filter loss and acid-rocks reaction retarded difficulty,those bring many difficulties to acid fracturing material and acid fracturing construction.On the basis of analysing acid fracturing modification technique puzzles of carbonate reservoir in Chexi buried hill,this paper mainly discusses acid fracturing modification process technique which is suited for this area reservoir property and implementation effects,then acquires some regular knowledges.
