摘　　要：X油田为我国海上一典型复杂断块油田,受储层物性和井身结构影响,水力压裂措施开展困难、常规酸化效果不佳,极大地影响了油田的生产。本文在对X油田情况进行深入分析的基础之上,并借鉴我国南海东部LF13-1油田开展爆压酸化技术的成功经验,从地质油藏条件和工程技术条件两个方面,分析了爆压酸化技术在X油田实施的可行性。结果表明X油田东营组和沙河街组,存在中低孔低渗、泥质含量较低、边底水位置满足条件的砂岩层段,可以开展爆压酸化。.Affected by reservoir quality and well structure, X oilfield, a typlcai complex brock oilfield, is difficult to implement well stimulation, such as hydraulic fracturing and acidizing, which greatly re- stricted the oilfield production. On the base of deep analysis of field condition, this paper proved the feasi- bility of applying de[lagration--fracturing and acidizing technique in X oilfield, from reservoir geology and engineering factor, also learning successful experience from LF13--1 oilfield. The study results show that there are suitable sandstone layer in Ed and Es formation for deflagration--fracturing and acidizing, with mid--low porosity ~ low permeability, low shale content, and proper edge--bottom water situation.
