摘要: 通过水锁损害、 滤液损害、 固相颗粒侵入损害等实验, 对低渗透缝洞型储层的损害机理进行了研究。 结果表明, 固相颗粒侵入损害是低渗透缝洞型储层的主要损害方式。设计了不加和添加渗透剂的两种颗粒状暂堵 剂配方, 结果表明, 在0. 2 5%K P A+4. 8%膨润土+0. 8 7%KC l +1%纤维封堵剂+2. 7%复合暂堵剂基础上, 添加1% 渗透剂的配方相比不添加渗透剂的配方, 在钻井液堵塞实验中, 能使渗透率堵塞率均值提高9%, 渗透率恢复值均值 提高9. 8%; 在返排解堵实验中, 渗透率恢复值也得到不同程度的提高, 最大达到1 2%。这表明该配方能有效提高储 层渗透率, 可以避免屏蔽环堵塞, 起到保护储层的作用。

Abstract: The damage mechanism of water locking damage, filtrate damage and solid particle invasion damage on low permeability seam cave type reservoir layer was studied. The results showed that the solid particle invasion damage was the main damage mode in low permeability fracture cave type reservoir. Hereby, two kinds of granular temporary plugging agent formula with and without penetrating agent were designed. The results show that, in drilling fluid plugging plug experiment, the permeability plugging rate value was increased by 9% and the permeability recovery value is increased by 9.8% when 1% penetrant was added to the compound temporary plugging agent composed with 0.25%KPA, 4.8% bentonite, 0.87%KCl, 1% fiber plugging agent and 2.7% compound temporary plugging agent. In the anti resolve plugging experiment, the permeability recovery value was also increased, and the maximum reached 12%. It shows that the formula can effectively improve reservoir permeability, avoid the shielding ring blockage, and play the role of protecting reservoir.
