西峰油田整体压裂方案优化设计

目前,在整体压裂优化设计方面,人们对五点井网和反九点井网的研究较多,而对菱形反九点井网的研究较少。根据长庆西峰油田菱形反九点井网类型和目前的地质条件,通过建立菱形反九点井网条件下带裂缝的油藏数值模拟模型和压裂方案优选决策模型,计算现有井网和裂缝方位条件下,多种压裂方案对油藏重要开采指标集的影响,通过综合分析确定合理的压裂方案,为西峰油田整体压裂效益的提高提供了科学依据。

Integral Fracturing Optical Design in Xifeng Oilfield

At present, more integral fracturing design research focus on five - spot well network and nine - spot well network but little on rhombus anti - nine- spot well network. According to rhombus anti- nine - spot well network of Changqing Xifeng Oilfield and current geologic condition, established fractured numerical reservoir simulation model and fracturing optical decision model, calculated and compared af fection of several fracturing scheme to exploitation index at current well network and fracture orientation circumstance, obtained appropriate fracturing scheme, provided scientific direction for fracturing benefit of Changqing Xifeng Oilfield.
