| description | For the rational development of Block S48, Tahe Oilfield, which is a fractured carbonate reservoir with bottom water, a correlation equation of its perforating level and well density is derived based on the oil and gas fluid flow mechanics and the oilfield performance. The rational well spacing under a certain perforating level and the rational open thickness under a certain well density can be determined by this equation. The rational perforating level should be less than 50% and at this value the well spacing is the largest. The rational open thickness decreases with the increase of water saturation during the development, and the open well sections should thus be closed gradually in oilfield production. As the rational open thickness will increase and the rational well spacing will decline correspondingly as the ratio between vertical permeability and horizontal permeability increases, unevenly distributed well pattern should be adopted according to the fracture developments in different areas. In the later period of well pattern thickening, the location of new wells and their perforating thickness should be determined by the actual parameters of existing wells. Key words: fractured reservoir, carbonate reservoir with bottom water, rational perforating level, rational well spacing |
