低渗透缝洞型储层损害及保护措施研究
T he Research of Low Permeability Fractured Reservoir Damage and Protection
摘要
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 2.5% KPA ,4 8.% bentonite ,0 8.7% 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 .关键词
