Abstract :
Pressure transient analysis model for Multiple Hydraulically Fractured Horizontal Well is proposed in this paper, which takes into account the adsorption effect and the diffusion effect of gas, the compression sensitivity effect, the wellbore storage and the skin factor. Applying Newman Product Principle, the semi-analytical pressure solution is presented. Considering the highly parallel infinite sum and integral in the solution, a GPU based parallel algorithm is implemented to accelerate calculation. Results on the platform with i3 540 CPU and NVIDIA GTX 550Ti GPU shows almost 40 times speedup, in which way the real time bottomhole pressure calculation of multiple fractured horizontal well is fulfilled.
