摘要
巴什托油田位于塔里木盆地巴楚县境内,属于巴什托断裂北盘的巴什托构造。随着塔河油田外围勘探程度的深入,在巴什托构造泥盆系克孜尔塔格组获得了重大油气突破,巴什托构造立体勘探有了进一步发展。巴什托泥盆系克孜尔塔格组油藏属于埋深大、异常高压、特低孔特低渗的低品位油藏。自2009年以来,陆续部署了4口开发井,但新井见产率低,储层改造效果较差,油水界面不统一,油气开发遇到较大困难,因此对该油藏特征进行分析有助于油藏的高效开发。
Abstract
The Yakela-Dalaoba Gas Condensate Field has accumulations deep buried with high temperature and pressure.During development,condensate water was found in gas wells in different extent,eSpecially in wellsin higher positions.Hydrocarbon components of gas condensate reservoirs areGated.Condensate water vapor in the component may influence facies changes and developmentcomplicharacteristics greatly.From the aspects of facies change andmicroseepage,the law and mechanism ofcondensate water generation were analyzed.The influence of condensatewater on the exploration of theYakela-Dalaoba Gas Condensate Fieldalso studied.The research may guide the dynamic analysis of the gas field.
