摘要 依据克拉玛依和百口泉油田砾岩油藏地质和开发特点,进行分类参数优选,经计算得到参数权系数及综合评价指标,对评价指标运用概率累计曲线分析后,将已开发区块分成了4类。并对各类区块进行了综合评价,在分类结果基础上制定了相应的开发调整对策:综合一类区块大力实施以挖掘剩余油为核心的局部井网加密调整,并通过加密直井选择性射孔达到层系开采的目的;综合二、三类区块主要实施井网加密与注采系统调整相结合的综合调整;综合四类在实施井网加密、注采系统调整、结构调整的同时进行非常规采油,如热力采油等。 According to the geology and development characteristics in the conglomerate oil reservoir in Karamay Oilfield, the classified parameters are optimized and the weight coefficients and comprehensive evaluating index of the parameters are calculated. After analyzing cumulative probability curve for the index, the developed blocks are classified into four types and moreover the comprehensive evaluation of each type of the block is carried out. On the basement of the above classification results, the corresponding development adjustment strategies are accomplished. For Type Ⅰ blocks, local well pattern thickening adjustment will be implemented, with remaining oil development as the center, and selective perforating will be adopted for the infill vertical wells in the hope of realizing the development of series of strata. For Type Ⅱ and Type Ⅲ blocks, an integrated adjustment will be implemented, including well pattern thickening combined with injection-production system adjustment. For Type Ⅳ blocks, well pattern thickening, injection-production system adjustment and structural adjustment will be implemented, simultaneously, non-routine method will be adopted for oil recovery, such as thermal recovery.
