摘要
目前海上油气田水平井常规产出剖面技术存在作业难度大、风险高、测试时间短等问题,导致难以精准地获得流体在整个水平段内的流动分布情况。利用连续油管分布式光纤产出剖面测井技术,可以实现全井筒实时温度和声波测量。该技术在海上X1气井获得了成功应用,通过录取不同生产制度下的光纤监测资料,利用井筒温度模型进行反演解释,并结合分布式光纤声波传感(DAS)数据综合定量分析,获得了该井产气剖面及产水层位,验证了海上产气井中连续油管光纤测井技术的可靠性和优势,为海上气田动态监测提供了新的技术手段,对于海上水平井找水作业具有重要意义。
Currently the conventional production profile technology of horizontal wells in offshore oil and gas fields has some problems,such as difficult operation,high risk,short test time and inability to obtain the flow distribution in the whole horizontal section.Using the coiled tubing distributed fiber optic production profile logging technology,it is possible to achieve real-time temperature and acoustic measurements throughout the wellbore.This technology has been successfully applied to an offshore gas well,where different production regimes were monitored using fiber optic sensors,and the wellbore temperature model was used for inversion and interpretation,combined with the fiber DAS data for a comprehensive quantitative analysis.This resulted in the determination of the gas and water production zones,verifying the reliability and advantages of the continuous tubing fiber logging technology for gas wells offshore,and providing a new technical means for dynamic monitoring of offshore gas fields.It is of great significance for horizontal wells searching for water in offshore horizontal wells.
