【摘要】：大慶長垣杏北地區(qū)高三組是大慶油田又一新的油勘探領(lǐng)域,為了研究大慶長垣杏北地區(qū)高三組油分布規(guī)律,更好的指導(dǎo)其油勘探,在油藏解剖及油水分布規(guī)律研究的基礎(chǔ)上,通過油分布與成藏條件之間關(guān)系分析,對(duì)大慶長垣杏北地區(qū)高三組油成藏主控因素及模式進(jìn)行了研究,并預(yù)測了油成藏的有利區(qū)帶。論文取得的主要成果有:(1)杏北地區(qū)高三組油藏可劃分為斷背斜油藏、斷鼻油藏、斷層遮擋、構(gòu)造-巖性、斷層巖性和巖性油藏6種類型。(2)杏北地區(qū)高三組油藏平面上零星分布,具有“西好東差”的特征,縱向上油主要分布于G34-5小層以上砂組中。(3)杏北地區(qū)高三組油成藏主要受到5個(gè)因素控制:①烴源巖供給控制了油氣平面分布為“西好東差”;②油氣運(yùn)移方向及路徑控制油氣成藏的區(qū)域;③輸導(dǎo)斷裂上調(diào)和頂部儲(chǔ)層發(fā)育造成油氣主要在淺部分布;④斷裂密集帶附近的正向構(gòu)造是油富集的主要部位;⑤遮擋斷裂側(cè)向封閉能力控制了油的富集程度。(4)建立了杏北地區(qū)高三組2種油成藏模式:①西北斜坡區(qū)油氣沿?cái)嗔炎呦?密集帶)運(yùn)移斷層封閉成藏模式;②西南斜坡區(qū)油沿砂體運(yùn)移反向斷層遮擋運(yùn)聚成藏模式。(5)優(yōu)選出杏北地區(qū)高三組1個(gè)Ⅰ類、3個(gè)Ⅱ類和2個(gè)Ⅲ類共6個(gè)油成藏的有利區(qū)。其中Ⅰ類有利區(qū)位于中央背斜帶西部杏69井西;Ⅱ類有利區(qū)位于西北斜坡區(qū)薩9-斜3井東、西南斜坡區(qū)杏5-3-丙040井北和中央背斜帶西部杏4-3-更23井北;Ⅲ類有利區(qū)位于中央背斜帶杏扶70-1井東和井西。
[Abstract]:The third formation of Gao 3 in Xingbei area of Daqing Placanticline is another new oil exploration field in Daqing Oilfield. In order to study the oil distribution law of high three formation in Xingbei area of Daqing Placanticline, and better guide its oil exploration, on the basis of reservoir anatomy and oil water distribution law,Based on the analysis of the relationship between oil distribution and reservoir forming conditions, the main controlling factors and models of oil accumulation in the third group of high school in Xingbei area of Daqing Placanticline were studied, and the favorable zones of oil accumulation were predicted.The main results obtained in this paper are as follows: (1) the reservoir in Xingbei area can be divided into six types: faulted oblique reservoir, fault nose reservoir, fault occlusion, tectonic-lithology, fault lithology and lithologic reservoir.The oil is mainly distributed in the sand formation above the G34-5 layer. The reservoir formation of the third group in Xingbei area is mainly controlled by five factors, the supply of 1 hydrocarbon source rock controls the distribution of oil and gas in the plane of "West, good and East".(2) the migration direction and path of oil and gas control the upregulation of oil and gas migration faults and the development of the top reservoir, which results in the oil and gas being mainly located in the forward structure near the dense belt of the shallow distribution of Jiao 4 faults, which is the main position of oil enrichment;(5) the lateral sealing ability of blocking faults controls the degree of oil enrichment. (4) two types of oil accumulation models of the third group of high grade oil in Xingbei area are established. The oil and gas accumulation model along the fault strike (dense zone) in the northwestern slope area of the northwestern slope is established.(2) the model of oil migration along the sand body along sand body to block accumulation and accumulation of oil in southwest slope area.) 6 favorable areas for oil accumulation were selected from three groups of high three groups in Xingbei area, I. e., class 鈪，
