水平井压裂产能电模拟实验研究

水平井压裂前须对其产能进行预测，通过电模拟实验，测量了水平井压裂模型的电压和电流密度，将实验数据转换为模拟油藏数据计算水平井压裂产能。实验结果表明，所采用的水平井压裂产能预测公式计算精度较高，实验和实际油藏条件下产能比值基本吻合。因此，在满足相似条件情况下，可以利用电模拟实验数据来表征水平井压裂产能的大小，从而达到快速预测水平井压裂产能的目的。

Experimental research on electric analogy of the productivity of fractured horizontal well

The productivity of the horizontal well should be forecasted before fracturing. Voltage and current density of the model of fractured horizontal well are measured in the electric analogy experiment. The productivity of the horizontal well may be calculated through converting the experimental data into the simulated oil reservoir data. The results of this experiment reveal that the adopted prediction formula is much accurate,and the tested productivity agrees with the reality. As fa result,the data of electric analogy experiment may characterize the values of the productivity of the fractured horizontal well under the similar conditions. The goal of high - speed prediction on the productivity of the horizontal well was achieved.
