Prediction method and application of caprock faulted-contact thickness lower limit for oil-gas sealing in fault zone
摘要
Abstract
Under the condition that caprock was not completely disconnected by fault in oil-gas bearing basins, a prediction method of caprock faulted-contact thickness lower limit for oil-gas sealing was established by comparing the sealing ability of fault rock and underlying reservoir rock. The method was applied to the No. 1 structure of Nanpu sag, where a prediction on the lower limit of the Ng3 volcanic caprock faulted-contact thickness for sealing the oil-gas in underlying Ed1 was made. The results indicate that the caprock faulted-contact thickness required by oil-gas sealing at fault f1 , f2 , f3 and f4 are all less than the actual faulted-contact thickness of Ng3 volcanic caprock, thus oil-gas are all sealed in the underlying Ed1 reservoir, which is consistent with the current oil-gas distribution in the Ed1 . This method is thus applicable to study the caprock faulted-con-tact thickness lower limit required by oil-gas sealing.关键词
