示踪剂监测井间动态技术研究及应用

示踪剂监测技术是用以描述油藏,监测油层有无高渗透层或大孔道存在,跟踪注水流向及贡献率,分析油水井注采状况和判断断层密封性的一种特殊的动态监测技术。三叠系长4＋5、长6油藏在早期的注水开发中,出现了部分井注入水单方向突进现象,引起主方向油井水淹,超低渗透引入示踪剂监测井间动态技术,对监测结果绘出示踪剂产出曲线加以分析,得出了储层井间连通状况,物性分布特征等参数,从而为评价储层非均质性以及油藏的注采调整提供了重要依据。

Research And Application On Tracer Iinter-well Dynamic Inspection Technology

Tracer inspection technology is a special dynamic inspection facility which is performed to discribe reservoir,identify the high peameability layers or huge pore,trace the motion of the injected water and its effect,analyse the flooding-withdrawl system and test the sealing property of the faults.In the early stage of the Chang 4＋5 and Chang 6 reservoir devolopment in Triassic,parts of the oil well in the dominant direction had been watered out as a result of the fingering.By using this technology in super-low peameability zones,the tracer production curve has been obtained and though which the interwell communication and parameters about the proporty distribution has been learned.So it serves for the evaluation to the heterogeneity and the adjustments to well pattern.
