Abstract:

Well pattern is the most important affecting factor to the ultimate recovery for an oilfield development. Many researches are reported on areal well pattern, which is widely used in conventional reservoirs development such as low permeability reservoirs, heavy oil reservoirs, multi-layer sandstone reservoirs, etc. In this paper, according to the geological characteristics of fractured buried hill reservoir of Liaohe Oilfield, we firstly present the concept of stereoscopic well patterns and compare it with common areal water flooding. By using numerical reservoir simulation method, we design and optimize the parameters of 5-spot stereoscopic horizontal well patterns, including payzone thickness and horizontal well length under different anisotropic factors of fracture permeability. This can be successfully applied on the development of MM block fractured buried hill reservoir of Liaohe Oilfield.
