摘　　要：南海西部海域北部湾盆地涠洲W油田四井区的油层中会常有"气层"出现,给该油田的开发调整规划造成一定困难。本文通过地层组分分析模型和最优化理论计算储层条件下溶解气和可动油的含量,确定储层逐点的气油比大小,根据计算得到的气油比从而达到识别储层流体性质的目的。实际应用表明,本文所应用的研究方法对含气油层和油层的识别有较明显的地质效果,并且与地层测试的结果较吻合,对其他盆地复杂流体性质的测井评价具有一定的指导意义。Gas-bearing layer often appears in the oil reservoirs of Weizhou W oilfield in Well4 area of western South China Sea,which brings some difficulties to the oilfield development adjustment plan.The content of dissolved gas and movable oil can be calculated with formation components analysis model and optimization theory under stratigraphic condition,then the gas oil ratio of oil reservoir is determined point to point.According to the calculated gas oil ratio,the goal of determining reservoir fluid is achieved.The application results show that this method has significant geological effect on distinguishing gas bearing oil pay zone in oil reservoirs,and the calculation results are identical with formation testing.It provides a successful experiences for complicated fluid property in other oilfield,and has a high application and reference value.
