油房庄油田属典型的低渗油田，储层非均质性严重，层间渗透率变异系数较大。在油田开发过程中，部分措施对储层造成了一定程度的伤害，从而使层间矛盾更加突出，严重影响了油田开发水平的提高。针对这一情况，2006—2007年共在油房庄油田实施暂堵酸化12井次，施工成功率100%，有效11井次，措施有效率达92%，增油量19.6 t·d-1，累积增油量2 296.72 t，取得良好效果。

Youfangzhuang Oilfield is a typical low permeability oilfield with very severe reservoir heterogeneity. The permeability variation coefficient is very different in the different layers. The reservoirs have been damaged to a certain extent by the use of some measures in the oilfield development process, which makes the interlayer contradictions more obvious and severely impacts the oilfield development. In view of this situation, the temporary plugging and acidization of 12 well times were implemented in 2006 and in 2007 in Youfangzhuang Oilfield. The operational success rate reached 100%. 11 well times are effective and the availability reaches 92%. The increased oil producing capacity is 1.96t per day.  The total increased oil production reaches 2，296.72t. The good effect has been obtained.
