随着大牛地气田2012年水平井大规模开发,越来越多水平井呈现出递减趋势,高产液水平井出现水淹停喷也随之增加.大斜度测试通过理论计算模拟,并结合现场经验,加工测试工具达到水平井井斜段测试要求.在气田顺利开展实验,并成功运用在水平井常规监测工作中,为水平井后期排采中积液、水淹提供较准确的预警手段.%With the large-scale application of horizontal well in Daniuqi gas field in 2012,more and more horizontal wells have shown a decreasing trend,and more flood and stop spray occur in high-yielding horizontal wells. The large slope test is simulated by theoretical calculation and combined with field experience,the machining test tool meets the test requirements of horizontal well. The experiment was carried out successfully in the gas field,and it was successfully used in routine monitoring for horizontal Wells. It provides an accurate early warning method for the effusion and flooding in the late drainage of horizontal Wells.
