2、分析測試等資料綜合分析的基礎(chǔ)上,結(jié)合模擬實驗對博興油田沙四上亞段灘壩砂巖儲層非均質(zhì)性特征及其對油氣成藏的影響進(jìn)行了分析。結(jié)果表明:研究區(qū)灘壩相儲層主要為砂泥薄互層狀分布,儲層非均質(zhì)性強(qiáng);油氣分布呈嚴(yán)重不均一性,不同井區(qū)、不同砂組含油特征迥異;成巖作用導(dǎo)致該區(qū)儲層質(zhì)量差異較大,儲層質(zhì)量與含油氣性有較好的正相關(guān)性.空間儲層非均質(zhì)性控制了油氣充滿度及宏觀分布特征。模擬實驗顯示,成藏動力和成藏阻力的配置關(guān)系會影響油氣的富集特征.并在一定程度上弱化儲層非均質(zhì)性對油氣成藏帶來的影響關(guān)鍵詞:儲層非均質(zhì)性;油氣不均一分布;模擬實驗;灘壩相儲層;博興油田;渤海灣盆地中圖分類號:TE
