| 摘 要： | 为了准确预测气体钻井施工过程中出水层位的地层出水量,根据渗流力学的基本原理,并结合气体钻井的实际工作状况,分别分析并建立了钻头钻入水层厚度小于井径、大于井径、完全钻穿水层和钻头已部分钻穿水层但尚未整体脱离水层四种情况下的地层出水量的理论预测模型。在塔里木油田的现场实验表明,理论模型的计算结果和现场实际测量的出水量相比误差在10%左右。该理论模型可以适用于气体钻井过程中出水层位出水量的计算,具有推广价值。

| Abstract: | To calculate the output of water producer in gas drilling,by using the fundamental principle of fluid mechanics in porous medium and combining the actual working condition of gas drilling,the theoretical model of water output is established in four different circumstances.The four circumstances includes the drilled thickness is less than or more than the well diameter,the bit has already drilled out the water layer,the bit has drilled out the water layer in part but has not broken away from the water layer.... |
