西峰油田白马区井网系统研究

nvestigation of the Well Net System of Baima Stratum in Xifeng Oilfield

西峰油田白马区长8储层属低孔、低渗储层，如何合理有效地开发低渗透储层，从而充分发挥地层潜能，提高油井单井产量至关重要。文中利用理论计算、经验公式、数值模拟、经济评价方法，充分论证了适合西峰油田低渗透储层开发的最佳井网形式，提出了菱形反九点法井网，井距520～540m，排距为180～220m是开发该类油藏的合理井排距，并在现场实践中取得了较好的开发效果。

The chang 8 stratum of Baima region in Xifeng oilfield falls into the low porosity, low permeability strata. It is very important to explore this kind of low permeability oilfield effectively so as to exert the strata potential sufficiently and increase the oil well productivity. Through theory numeration, experience formula, numerical simulation and ecnomic evaluate, this paper demonstrated the optimal well net system adapts to the low permeability strata such as the Xifeng oilfield and brought forward the rhombus anti nine points well net. It is approved that the well space between 520 to 540 meter and the row space between 180 to 220 meter is the appropriate well and row space, which is testified in the local practice with a prefect exploitation effect.
