【摘要】：本論文以層序地層學(xué)、構(gòu)造地質(zhì)學(xué)、地震儲(chǔ)層預(yù)測理論為指導(dǎo),通過對黑帝廟油層黑二段的地震、測井資料的綜合分析應(yīng)用,完成了該研究區(qū)的構(gòu)造特征和儲(chǔ)層特征的研究。在本次研究中,通過對黑帝廟油層黑二段地震資料和測井資料的結(jié)合,以合成地震記錄為橋梁,完成了H21、H22、H23三個(gè)反射界面的追蹤對比解釋,并在此基礎(chǔ)上編制了相應(yīng)的構(gòu)造圖,初步研究了該研究區(qū)黑二段的構(gòu)造特征。依據(jù)地震剖面斷層解釋原則,并結(jié)合相干體與三維可視化等方法手段,對該工區(qū)黑二段地層進(jìn)行斷層識別,綜合分析黑二段構(gòu)造特征。通過分析本研究區(qū)的構(gòu)造特征、沉積背景和儲(chǔ)層特點(diǎn),對黑二段區(qū)塊進(jìn)行反演預(yù)測工作。在資料預(yù)處理的基礎(chǔ)上,結(jié)合曲線敏感性分析,以頻率補(bǔ)償原理進(jìn)行曲線重構(gòu)反演,從而預(yù)測砂體分布特征。通過對黑二段地震屬性、砂體分布、沉積特征、物性的研究,建立起儲(chǔ)層預(yù)測研究思路并預(yù)測有利井位。區(qū)內(nèi)斷裂十分發(fā)育,規(guī)模較大的斷裂主要分布研究區(qū)西南部,走向?yàn)楸蔽飨驗(yàn)橹?有利區(qū)主要分布在西部構(gòu)造高部位,斷裂發(fā)育,巖性上傾、側(cè)向尖滅明顯,是烴源巖油氣的有利運(yùn)移位置,在地震反演切片、甜點(diǎn)屬性和頻譜分解地震屬性表明,地震屬性在研究區(qū)中部自西北向東南發(fā)育一貫穿全區(qū)的長條狀屬性異常組合,反演結(jié)果表明黑二段油層屬于三角洲外前緣沉積體系為主,個(gè)別發(fā)育濱淺湖相沉積,砂巖相對較發(fā)育,儲(chǔ)層物性差,形成了現(xiàn)今的砂巖油氣儲(chǔ)集層。
[Abstract]:This paper is guided by sequence stratigraphy, structural geology and seismic reservoir prediction theory, through the comprehensive analysis and application of the seismic and logging data of Heidimiao oil formation. The structural characteristics and reservoir characteristics of the study area have been studied. In this study, through the combination of seismic data and logging data of the Heidimiao oil reservoir, the synthetic seismic record is used as a bridge to complete H21. On the basis of tracing and contrast interpretation of the three reflection interfaces of H22 and H23, the corresponding structural maps are compiled, and the structural characteristics of the second member of Heihe formation in the study area are preliminarily studied, according to the principle of seismic section fault interpretation. Combined with coherence and 3D visualization methods, fault identification and comprehensive analysis of the structural characteristics of the Hejie formation in this area. Through the analysis of the structural characteristics of the study area, sedimentary background and reservoir characteristics. On the basis of data preprocessing and curve sensitivity analysis, the inversion of curve reconstruction is carried out with the principle of frequency compensation. Based on the study of seismic attributes, sand body distribution, sedimentary characteristics and physical properties of the second member of Heihe formation, the reservoir prediction and prediction of favorable well location are established. The faults in the area are well developed. The large scale faults are mainly distributed in the southwest of the study area, with the strike of NW as the main direction, and the favorable areas mainly distributed in the high part of the structure in the west, the faults are developed, the lithology is inclined up, and the lateral pinnacles are obvious. It is the favorable migration position of hydrocarbon source rock in seismic inversion section, desserts attribute and spectrum decomposition seismic attribute. The seismic attributes developed from northwest to southeast in the middle of the study area. The inversion results show that the oil layer of the second member of the Heihe formation belongs to the depositional system of the outer delta front. Some developed shallow lacustrine facies, the sandstone is relatively developed, and the reservoir physical property is poor, forming the present sandstone oil and gas reservoir.
