Abstract

Since conglomerate reservoir has strong original heterogeneity,the injection-production contradiction is very serious,waterflow superiority channels exist in some of the strata,and the water injection development is affected seriously.The particle plugging agent with high strength and slow expansion can swell slowly in the process of the injection,and it can go into the deep bed of the layer effectively,then swell as big as possible to plug off the high permeability layers and the crack strips.With this characteristic,it can plug in the deep effectively,so we carried out the integral profile controlling field test and effectiveness analysis in conglomerate reservoir.Results of the six Middle East blocks in Xinjiang province show that particles with high strength and slow expansion improved the serious heterogeneity and water flooding effect of the conglomerate reservoir effectively.Three years after the construction in the experimental block,the accumulative oil increment is 34 226t,and the oil recovery enhanced by 8.38%.
