       承压堵漏剂是一种集高失水、高强度、 高承压于一体的堵漏剂。堵剂浆液泵入井下遇到漏层,在压差作用下迅速失水,很快形成具有一定初始强度的滤饼而封堵漏层,其初始承压能力可达到4MPa以上;在地温的作用下,所形成的滤饼逐渐凝固,其强度读值可达到30 KN以上,可使其漏层的承压能力得到大幅度提高。堵塞物(滤饼)的酸溶率达80%以上,有利于酸化解堵,可用于产层井漏的处理,以达到保护产层的目的。该产品适用于孔隙性和裂缝性漏层的处理。
       Pressure plugging agent is a high loss of water, high strength, high pressure in one of the plugging agent. When the slurry of plugging agent is pumped into the leaking layer, it will lose water quickly under the action of pressure difference, and soon form a filter cake with a certain initial strength to seal the leaking layer, whose initial bearing capacity can reach over 4 MPA, the filter cake gradually solidified, its strength reading value can reach more than 30kn, which can greatly improve the pressure bearing capacity of the leakage layer. The acid solubility of the plugging material (filter cake) is more than 80% , which is favorable for acidizing and plugging removal, and can be used to deal with lost circulation in pay zones in order to protect pay zones. This product is suitable for the treatment of porous and fractured leaking layers.
