| 摘 要： | 镇泾油田长8油层具低孔特低渗特征.在储层沉积、成岩作用和储集特征研究的基础上,通过岩性圈闭形成条件、成藏动力、储层流体充注临界物性、圈闭形成和油气充注时间以及高产富集控制因素等方面对镇泾长8特低渗岩性油藏的形成机制开展了研究,得出了以下主要结论:①镇泾油田长8油层组具备形成大中型岩性油藏的有利条件;②储层沉积微相是岩性油藏形成的基本控制因素;③"三元成藏"(流体充注动力、储层临界物性和成藏窗口)构成镇泾长8岩性油藏形成的主控因素;④油藏的富集高产主要受有利储集相带控制,并受到天然裂缝的影响.

| Abstract: | The Chang8 oil formation in the Zhenjing Oil Field is characterized by low porosity and ultra-low permeability.Based on the studies of reservoir deposition,diagenesis effect and storage characteristics,the generation mechanism of lithologic reservoir with ultra-low permeability in the Chang8 oil formation has been studied from several aspects such as lithologic trapping condition,accumulation dyna-mics,threshold for fluid charging,time for trapping and petroleum charging as well as controlling factor for sw... |
