欧利坨子和黄沙坨油田粗面岩储层预测技术及应用
|
摘要
粗面岩储层预测技术成功地应用在欧利坨子和黄沙坨油田,特别是千万吨级储量规模的黄沙坨油田的建成,带动了整个辽河油区特种油气藏的勘探进程。欧利坨子和黄沙坨油田位于辽河盆地东部凹陷中北段,其发育的主要含油气储层为粗面岩储层。通过充分利用钻井、录井、测井解释及试油资料,并结合地震资料,采用地震属性和地震反演等技术,预测了粗面岩储层的厚度、分布范围及裂缝等,分析认为该区储层主要为裂缝型储层,且储层发育,有利于油气聚集成藏,因而对该区下步勘探具有重大的意义。
Trachyte reservoir prediction technique has been successfully applied in Oulituozi and Huangshatuo oilfield, especially Huangshatuo oilfield has been built with reserves of ten millinos of tons , the process of special oil-gas bearin greservoir exploration has been driven in whole Liaohe oilfield Oulituozi and Huangshatuo oilfield are located in north central Dongbu depression of Liaohe basin , and the most important oil-gas bearing reservoir is trachyte reservoir .This paper studies drilling, logging , logging intepretation,oil production testing and the seismic data , applies the seismic attribute and the seismic inversion , forecasts the thickness, distribution and fracture of trachyte reservoir . The study indicates that the reservoir is fractured reservoir, it is well-developed and favorable for oil and gas accumulation inthe area . The result of this study may guides the following exploration in this area.
