摘　　要：突破传统屏蔽暂堵技术观念 ,针对层间差异较大的高孔、高渗储层 ,将不同类型的油层保护剂加入黑色正电胶体系 ,研制出一种广谱暂堵型保护油气层钻井完井液体系。该体系能够对不同渗透特性的储层进行瞬时镶嵌式封堵与纤维架桥作用 ,减少粘土颗粒的侵入污染 ,抑制油气层中的粘土水化膨胀 ,减少了处理剂对油气层的污染 ,有利于反排和渗透率恢复。试验结果表明 ,该体系封堵率达 10 0 % ,煤油反排渗透率恢复率达 90 %以上。A new theory on shielding and plugging techniques is raised breaking through the traditional ideas. By adding different kinds of temporary slugging agents to the black positive electric colloidal drilling fluid, a new system named superior shielding and slugging drill in fluid which has excellent formation protection mechanism is developed for the oil reservoir with high porosity and high permeability. With such advantages as the spurt inlaid slugging generated by solid particles whose diameters are equal ...
