Abstract

Volume fracturing aiming to induce a complicated fracture network is a key measure to acquire commercial productivity in tight formation where the selection of optimal cluster spacing is important and essential. Therefore most numerical simulation is mainly used to obtain the optimal cluster spacing, but not often considered with the effect from transverse fractures interference. Based on a new analytical solution methodology for multiple equally spaced stage/cluster transverse fractures, this paper presents a simple and efficient approach added the interference (like flow rate interference, stiffness interference, fluid loss interference ) among multiple transverse fractures to acquire the optimal cluster spacing with the goal of maximizing the oil production. Meanwhile, it results that adequate big cluster spacing is not good to create complex fracture network and much less one easily results in strong effect on production due to fractures interference. The paper provides references for optimizing volume fracturing design and planning rational development strategies in this area.
