ABSTRACT

In this paper, a five-spot well pattern was established, which completely took into consideration the production characteristics of low-permeability reservoir and fracture flowing characteristics. The numerical simulation method was used to analyze the influence of fracture conductivity and fracture length on well production performance. These parameters, which could guarantee field production rate and field oil recovery to reach the highest value, are selected as the optimal hydraulic fracture parameters. According to the above theory, the fracture parameters of Z23 were optimized, and stimulation results showed that the production performance was largely improved.
