Abstract
In the acid fracturing of naturally fractured carbonate reservoirs,
excessive acid leak off is the main factor limiting fracture propagation and
live acid penetration distance. To reduce acid leakage and enhance the
stimulation effect, ceramsite loss control agents have been widely applied in
acid fracturing. However, the leak off reduction behavior of ceramsite has not
yet been systematically investigated. Therefore, a conventional core-flooding
acidizing system with a hollowed-out Hastelloy cylinder was used to perform a
series of acid leak off experiments. Experimental results show that 1. The
smaller the size of the ceramsite, the better the filtration reduction effect;
2. The higher the injection rate, the greater the acid carrying capacity, which
is conducive to the loss of the control agent entering the fracture and
acid-etched grooves; and 3. Under laboratory conditions, the optimal ceramsite
dosage is 4 g. This study deepens the understanding of acid leak off in
carbonate reservoirs and provides fundamental information for field acid
fracturing design.
