摘　　要：文72块沙三中油藏是一个高压异常高含盐油藏。沉积物的快速沉积、高地温梯度、封闭性断层、盐刺穿及侧向挤压和充足油气源等方面的因素是形成高压异常的原因;咸水湖泊的沉积环境是地层水及原油高含盐的原因。建立了流体封存箱模式,并提出了钻井和开采中要注意的问题。Wen Block 72 middle oil reservoir is the reservoir with high pressure and containing salt oil.The causes of forming high pressure are clastic matter depositing fleetly,high grads of stratum temperature,salt cutting through and crushing from side,rich fountainhead of oil and gas well,etc.The salt water lacustrine depositional environment is the reason of the stratum water and crude oil containing high salt.It has been set up and also has been brought forward the questions that should be paid attention to in drilling and developing.
