摘　　要：自从暂堵和架桥的思想被广泛应用于石油行业以来,产生了许多有影响力的屏蔽暂堵理论。结合目前最为先进的屏蔽暂堵理论——D90和d1/2理论,形成了一套优选屏蔽暂堵剂类型的新方法。并依据最小二乘法思想,编制了屏蔽暂堵剂优选配套软件。该软件操作简单、实用性强。利用该软件优选了适合于吉林油田大情字区块的屏蔽暂堵剂。并对添加了该暂堵剂的钻井液体系进行室内评价实验,评价结果表明:滤失量明显降低,渗透率恢复值有了很大程度的提高,验证了该种方法的合理性。Since the temporary plugging and bridging theory are widely used in petroleum industry.Many influential shielded temporary plugging theory have appeared.Combining the most advanced shielding and temporary plugging theory-D90 and d1/2 theory,a new method for optimizing the types of shielded temporary plugging agents was formed.And based on the least squares method,draw up the software for optimizing shielded temporary plugging agents and calculating ratio.This software is easy in operation and better on practicability.Shielded temporary plugging agents are optimized with this software which are suit for Daqingzi Area in Jilin Oilfield.Laboratory experiment was done for evaluating added temporary plugging drilling fluid system.The evaluation results show that: the filtration reduced significantly,and permeability recovery value have a large degree of improvement,the rationality of the method is validated.
