The sandstone reservoir in the Lule River group of Mahai East District is strong, densely dense, and the expansion of clay material is very easy to block the pores.Therefore, the new pressure cracks click here and cationic cluster stabilizers with double-season ammonium salt clay stabilizers are used.Experimental analysis is performed under the circumstances of the perimeter.

Use nuclear magnetic real-time testing different fracture liquids to drive the pore structure structure changes before and after the sandstone, combined with differential theory to calculate the fractal dimensions of sandstone.As a result, under the condition of water full, as the perimeter pressure increases, the rocks are increased, and the rocks are increased, and the rocks are increased.The matrix occurs under the common action of the fence and the fracture fluid to prevent the inflation of clay minerals under the combined action of the fence and the fracture fluid, which causes read more a significant reduction in large holes and increased micropores and medium holes.

Exploring different fracture liquids to reservoirs is of great significance to the development of dense sandstone reservoirs.
