A Practical Method to Predict Productivity of Multistage Fractured Horizontal Well in Tight Oil Reservoirs

doi:10.7657/XJPG20190615

Abstract

Abstract: To solve the problem of the large errors in multistage fractured horizontal well productivity prediction in Mahu tight oilfield, the authors investigate the research status and countermeasures at home and abroad, conclude that the reason leading to large errors is the strong reservoir heterogeneity and it is difficult to solve the horizontal heterogeneity problem by using the formula method to predict horizontal well productivity. A tight oil productivity prediction procedure is established for horizontal wells by using stimulation ratio method. Firstly, the correlation between vertical well productivity and geological parameters is established and then the correlation between the stimulation ratio of horizontal well (horizontal well productivity divided by vertical well productivity) and geological parameters, finally the planar distribution of horizontal well productivity can be predicted. The actual production from newly-drilled wells proves that the accuracy of the new prediction method is higher than those of analogy and formula methods.Keywords:
