Abstract: This paper has estimated the engineering geologic features of Penglai zhen formation in Luodai gasfield of West Sichuan, and carried out feasibility assessment on foam fracturing in Luodai gasfield. With the most popular FracPT fracturing design software, by adopting constant inner phase design method, this paper optimizes the foam fracturing design parameters, and forms a set of foam fracturing construction scheme for the Penglaizhen formation. Through comparison with conventional hydraulic fracturing, the foam fracturing in West Sichuan shows great potential.
