摘要:

微地震评价压裂效果价格昂贵，压裂液返排数据未能很好利用。基于PEBI网格对水相方程进行数值求解，利用无

限导流主裂缝与导致渗透率扩大的分支缝描述压裂改造区域，利用初始压力分布描述压裂液对储层的影响，建立了基于返排数据的致密油大规模多段压裂水平井的压裂

效果评价方法。采用该方法对大庆油田某致密油藏多段压裂井水平井的返排数据进行解释，压裂改造区域宽度为527 m，微地震解释压裂改造区域宽度为493 m，相对误

差为69%，结果可靠。该方法可充分利用已有数据，大幅降低当前压裂效果评价成本。

Abstract:
 

The cost of evaluation the fracturing effect using the microseismic was

expensive, and the fracturing fluid flowback data were not fully utilized. In this paper, the PEBI grid was used to numerically solve the water

phase equation, the main fracture with infinite flow conductivity and the branch fracture leading to the expansion of permeability were used to

describe the fracturing area and the initial pressure distribution was used to describe the influence of fracturing fluid on the reservoir. As a

result, a method for evaluating the fracturing effect of largescale multistage fracturing in horizontal wells of tight oil based on backflow

data was established. This method was used to interpret the backflow data of horizontal wells in a multistage fracturing well in a tight

reservoir in Daqing Oilfield. The interpretation results show that the width of the fracturing zone was 527 m, while the microseismic

interpretation result was 493 m. The relative error between these two values was 69%, which means that the result was reliable. This method can

make full use of existing data and greatly reduce the cost of current fracturing evaluation.
