XW地区油藏相态特征实验研究

摘要

There is high gas-oil ratio in producing test of oil wells in XW 6 fault block .As a result ,it is difficult to ob-tain high pressure oil samples by the conventional methods .According to the reservoir characteristics ,it was obtained MDT original formation fluid samples from XW6-1 well.And then it was carried out an experimental study on the phase charac-teristics of reservoir in XW region .Experimental results indicated that the reservoir is weak volatile oil one .Thus it was proposed the next step development suggestion .%XW6断块油井试采时生产气油比较高，常规方法求取高压物性样品难度大。针对油藏特点在XW6-1井获取了MDT原始地层流体样品，开展了XW地区油藏相态特征实验研究，根据实验结果利用多种方法进一步确定了该油藏的油藏类型为弱挥发油藏，并结合相态特征提出了下步开发建议。
