【摘要】：為了研究大柳泉構(gòu)造帶沙三中亞段下生上儲(chǔ)式油氣成藏規(guī)律,在源、儲(chǔ)、輸導(dǎo)、圈閉等成藏要素的發(fā)育及分布特征研究的基礎(chǔ)上,對(duì)其成藏貢獻(xiàn)進(jìn)行了研究.研究表明:油氣運(yùn)移條件與油氣保存條件是控制大柳泉構(gòu)造帶油氣富集程度的兩個(gè)最主要的影響因素.油氣運(yùn)移條件包括垂向運(yùn)移條件,側(cè)向分流條件和側(cè)向運(yùn)移條件,油氣保存條件包括蓋層垂向封閉性和控圈斷層側(cè)向封閉性.根據(jù)鉆井資料提出一種新的油氣運(yùn)移、保存條件評(píng)價(jià)方法,即油氣運(yùn)移指數(shù)與油氣保存指數(shù).通過(guò)分析對(duì)比已鉆井油氣運(yùn)移、保存指數(shù)與油氣富集各影響因素的定量關(guān)系,建立出預(yù)測(cè)未鉆井圈閉油氣富集程度的評(píng)價(jià)公式.運(yùn)用該方法對(duì)大柳泉構(gòu)造帶沙三中亞段各圈閉油氣富集程度進(jìn)行預(yù)測(cè),其結(jié)果與當(dāng)前鉆探成果有很高的符合率.
[Abstract]:In order to study the law of oil and gas accumulation in the middle part of the third member of the Daliuquan structural belt, based on the study of the development and distribution characteristics of the reservoir forming elements, such as source, reservoir, transport, trap, etc, the contribution of the reservoir formation is studied.The results show that the oil and gas migration and preservation conditions are the two most important factors to control the oil and gas enrichment in the Daliuquan structural belt.Oil and gas migration conditions include vertical migration conditions, lateral distributary conditions and lateral migration conditions, and oil and gas preservation conditions include vertical sealing of caprocks and lateral sealing of faults in control circles.Based on the drilling data, a new evaluation method of oil and gas migration and preservation conditions is proposed, that is, oil and gas migration index and oil gas preservation index.By analyzing and comparing the quantitative relationship between oil and gas migration, preservation index and various factors affecting oil and gas enrichment, an evaluation formula for predicting the degree of oil and gas enrichment in undrilled traps is established.The method is used to predict the oil and gas enrichment degree of each trap in the middle part of Sha 3 in the Daliuquan structural belt. The results are in good agreement with the current drilling results.
