摘　　要：深大断裂控制油藏储集层埋藏深,厚度大,油井难以钻穿整个油层。针对断控油藏油柱高度计算,建立了断控油藏油柱高度物理模型,并在此基础上,阐释了井筒温度剖面推算法的思路,推导了油水柱压力系数折算法计算油柱高度的公式,提出了考虑长方体泄流区域的动态储量反算法和考虑重力影响的等值渗流阻力法。应用这4种油柱高度计算方法,对塔里木盆地富满油田某断控油藏的2口井进行计算,结果表明,这4种方法计算的油柱高度具有一致性,2口井的平均油柱高度分别为675.39m和634.60m。The reservoirs controlled by deep and large faults are generally thick and deep.Therefore,a well cannot penetrate completely through an entire reservoir.For calculating the oil column height in fault-controlled reservoirs,a physical model of oil column height in fault-controlled reservoir was established.On this basis,the idea of the wellbore temperature profile extrapolation method was discussed,a for-mula for calculating oil column height with the conversion method of oil-water column pressure coefficient was derived,and the dynamic re-serves inverse method considering the cuboid drainage area and the equivalent flow resistance method considering the influence of gravity were proposed.The four methods were applied to two wells drilled into a fault-controlled reservoir in Fuman oilfield of Tarim basin.The re-sults show that the oil column heights calculated by the four methods are consistent,and the average oil column heights of the two wells are 675.39 m and 634.60 m,respectively.
