宋芳屯油田葡萄花油层属于低渗透隐蔽型油藏． 采用实验室储层敏感性评价实验程序， 针对油田钻井和注水开发实际工作条件，进行了多种储层敏感性测试． 实验结果表明： 受储层孔隙结构特征以及粘土矿物含量和组成的影响，研究区储层呈现中等～强盐敏性和弱～中等速敏性． 渗透率低于１５ ×１０ － ３ μｍ ２ 时，储层速敏性增强，储层受到泥浆伤害后，渗透率损失较大，难以恢复． 应该减少泥浆浸泡时间，选用高效射孔弹，解除泥浆污染． 采用清水注水开发储层呈现弱水敏性． 污水回注导致储层中～强水敏性，回注前应加以处理，确保悬浮物及高价阳离子含量达标． 普通酸化液酸化效果差 Songfangtun Putaohua oil reservoir belongs to the low permeability concealed reservoir. Based on laboratory reservoir sensitivity evaluation experiment program, a variety of reservoir sensitivity tests were conducted according to the actual working conditions of oilfield drilling and waterflooding. The experimental results show that the reservoirs in the study area present moderate to strong salt sensitivity and weak to medium sensitivity due to the pore structure characteristics of the reservoir and the clay mineral content and composition. When the permeability is less than 15 × 10-3 μm 2, the velocity sensitivity of the reservoir is enhanced. After the reservoir is damaged by mud, the permeability loss is large and it is hard to recover. Should reduce the mud soaking time, the selection of highly efficient perforating bombs to lift the mud pollution. The use of water injection development of reservoirs showing weak water sensitivity. Re-injection of wastewater leads to ~ strong water sensitivity in the reservoir and should be handled before re-injection to ensure that the suspended solids and high-priced cations reach the standard. Ordinary acidification acidification poor results
