摘要: 基于分布式光纤(DTS)的井下温度测试正逐渐被用于监测压裂水平井井下生产状况,但低渗气藏气水两相渗流压裂水平井的温度剖面预测和出水位置诊断仍是一个技术难题。在考虑多种微热效应的基础之上,建立了一套低渗气藏两相渗流情况下压裂水平井的耦合温度预测模型。采用建立的温度模型,分别模拟了一口低渗气藏压裂水平井在5种不同产水量分布情形下的井筒温度剖面,并分析了产水量分布对井筒温度剖面的影响规律。温度剖面预测结果表明:单相气体渗流压裂水平井裂缝位置处的温降与裂缝半长基本上成正相关、各级裂缝的温度特征值从趾端到跟端呈递减分布;而产水时,出水裂缝对应的井筒温降和温度特征值均呈现出“异常降低”现象。根据上述井筒温降和温度特征值的“异常降低”现象,分别介绍了在已知和未知裂缝半长的情况下,基于井下温度剖面测试诊断压裂水平井出水位置的方法。
