摘要：

Preflushes and overflushes are commonly used in fracture acidizing. Preflushes are useful for cooling the fracture, improving fracture geometry, and lowering the fluid loss of the acid solution that follows. While attention is generally given to viscosity in treatment design, fluid density has not been considered previously. This paper presents information obtained from model studies on the effect of fluid density using a vertical-fracture flow cell and from field treatments. These studies show that acid can be placed selectively in a vertical fracture by controlling the density and viscosity of the preflush. 4 refs.
