摘要:
 

大庆油田长垣扶杨油层试油压裂后，无法准确判别水性，不能对储层进行正确的认识和评价。通过计算扶杨油层储层出口端的含水率fw以及

油水相对渗透率比值Kro/Krw随试油试采时间的变化关系，判定储层是否产水，建立了大庆油田扶杨油层压裂后水性综合判别方法，并给出划分地层产

出液性质的量化指标。利用试油试采生产数据，计算松辽盆地中央坳陷区扶杨油层Kro/Krw及fw变化关系，判别其中9口井10层的地层出水规律，

与试油试采结果符合率达90%。该方法可及时准确判断扶杨油层试油压裂后地层产水性质，对缩短试油排液求产周期，提高油田整体效益，具有一定现实意义。

Abstract:
 

After well test and fracturing of Fuyang reservoir in Changyuan, Daqing Oilfield, it is

impossible to accurately distinguish the water property and correctly understand and evaluate the reservoir. By calculating the relationship between

water cut (fw) and oilwater relative permeability ratio (Kro/Krw) at the outlet of Fuyang reservoir with well test and

production test time, it is determined whether the reservoir produces water. Therefore, the comprehensive discrimination method of water property after

fracturing in Fuyang reservoir of Daqing Oilfield is established, and the quantitative index for dividing the properties of formation produced fluid is

given. Using the production data of well test and production test, the variation relationship of Kro/Krw and fw in Fuyang

reservoir in the central depression of Songliao basin is calculated. The formation water production law of 10 reservoirs in 9 wells is distinguished by

the modified method, and the coincidence rate with the results of well test and production test is 90%. This method can timely and accurately

judge the formation water production properties after oil test and fracturing in Fuyang reservoir and has certain practical significance for

shortening the production cycle of oil test and drainage and improving the overall benefit of the oilfield.
