摘要
在模拟地层上覆压力、地层压力、地层温度和地层含水饱和度的长岩心上,模拟不同生产压差下的气体流速实验,确定了川西蓬莱镇组气藏的单井合理产量为压裂前922m3/d至3072m3/d,按平均增产5倍计算,蓬莱镇组气藏压裂后的单井合理产量为4600m3/d至15400m3/d,反推的单井无阻流量为18400~118300m3/d,与气藏实际值基本一致。
According to the gas velocity of flow experiment under different drawdown pressure on long cores with simulative overburden pressure, formation pressure, temperature and water saturation, the (reasonable) production of single well of Penglaizhen reservoir in west Sichuan is determined to be 922 m^3/d to 3 072 m^3/d before hydraulic fracturing. If calculated by increasing quintuplicate average production rate, the reasonable production of single well is 4 600 m^3/d to 15 400 m^3/d after hydraulic fracturing, and open flow potential is 18 400~118 300 m^3/d by reversal derivation, which is consistent with actual value of gas reservoir on the whole.
