【摘要】 针对迪那2气田带裂缝异常高压凝析气藏特点,开展了考虑流态、相态、温度、动能损耗和动态摩阻等因素的压力动态评价方法研究。在此基础上,进行了考虑应力敏感的试井解释和产能评价方法研究,编制了相关计算软件,初步形成了迪那2异常高压凝析气田压力评价、试井解释及产能评价技术。通过实例证明,该系列技术能通过井口压力动态监测数据求得储层物性参数等资料,为该类气藏合理、高效开发提供技术支持。更多还原

【Abstract】 Gas Field Dina 2 is characterized with abnormal high pressure,condensation and having fractures,a study of evaluation method about pressure performance affected by flow state,phase,temperature,kinetic energy losing and dynamic friction etc. is performed. Further more,a study of method about well test interpretation and deliverability evaluation is performed,which takes the stress sensitivity into account,and appropriate software is developed. The technology of pressure evaluation,well test interpretation and deliverability evaluation in condensate Gas Field Dina 2 with abnormal high pressure is preliminarily formed. Given examples prove that the technology can provide physical parameters of reservoir by wellhead pressure monitoring,and so provides technological support for development this kind of gas reservoir rationally and efficiently.更多还原
