【摘要】：升平地區(qū)深層營(yíng)城組天然氣藏其主要儲(chǔ)層火山巖的巖性、物性特征和天然氣藏分布規(guī)律都十分復(fù)雜,火山巖儲(chǔ)層的天然氣產(chǎn)能與裂縫的發(fā)育程度關(guān)系密切,氣田開(kāi)發(fā)急需精細(xì)的火山巖儲(chǔ)層裂縫發(fā)育及成藏分析的研究成果。本文通過(guò)對(duì)升平地區(qū)天然裂縫發(fā)育特征、MVE應(yīng)力分析、三維地震資料裂縫預(yù)測(cè)及天然氣成藏條件進(jìn)行了深入研究,結(jié)果表明研究區(qū)主要發(fā)育構(gòu)造縫、張裂縫及網(wǎng)狀縫,其次為成巖縫。裂縫多數(shù)被充填~半充填,只有少部分開(kāi)啟,有效儲(chǔ)層段主要以大縫、低角縫以及高角縫為主,鏡下觀(guān)察微裂縫發(fā)育,主要為張裂縫、網(wǎng)狀縫;天然裂縫的發(fā)育方向主要為北西向及近南北向,有少數(shù)裂縫發(fā)育方向?yàn)榻鼥|西向,鉆井誘導(dǎo)縫主要發(fā)育方向?yàn)榻鼥|西向,少數(shù)為近南北向。儲(chǔ)集空間類(lèi)型以構(gòu)造縫、氣孔、斷層破碎帶的巖石粒間孔隙為主。組合成裂縫-孔洞型儲(chǔ)層,儲(chǔ)集空間的分布具有強(qiáng)非均質(zhì)性。該區(qū)孔縫的發(fā)育帶在電阻率、密度及吸收系數(shù)屬性上的反映比較敏感,通過(guò)對(duì)這三項(xiàng)屬性處理后所形成的綜合數(shù)具體分析,裂縫發(fā)育帶的預(yù)測(cè)與已知鉆探結(jié)果具有較好的一致性。研究區(qū)氣藏類(lèi)型豐富,主要有火山巖斷背斜巖性復(fù)合氣藏、火山巖地層超覆復(fù)合氣藏和構(gòu)造-巖性氣藏。升平氣田主要發(fā)育斷裂成藏體系,包括深大斷裂相伴生,受斷層裂縫控制的深部火山巖成藏模式和以斷裂作為運(yùn)移通道的上部砂巖氣藏成藏模式。
[Abstract]:Deep city Shengping area and operation of natural gas reservoir group the main reservoir volcano rock lithology, physical properties and gas reservoir distribution are very complex, natural gas production capacity and crack of volcano rock reservoir development degree is closely related to gas field development need fine volcano rock reservoir fracture development and research into the reservoir this paper through analysis. Characteristics of natural fractures developed in Shengping area, the stress analysis of MVE, the prediction of 3D seismic data of crack and gas accumulation conditions were studied, results showed that the study area mainly developed structural fractures, tension cracks and net fracture, followed by diagenesis. Most cracks were filled and half filled, only a few open, effective reservoir mainly to large joints, low angle fractures and high angle fractures and micro fractures under microscope, mainly for crack, reticular joint; the development direction of natural fractures is the main North West and nearly north-south, have A crack growth direction is nearly east-west, the main development direction of seam is nearly EW induced by drilling, a nearly north-south. Reservoir space types in structural fracture, fault fracture zone of rock pores, intergranular pores. Combined into fractured vuggy reservoir, the distribution of the storage space has strong heterogeneity the District Development Zone in hole resistivity, density and absorption coefficient to reflect on the properties of more sensitive, through a comprehensive number of the formation of these three attributes after concrete analysis of fracture zone prediction with the known drilling results have good consistency. The study area is rich in gas reservoir types, main volcano rock faulted anticline lithologic composite gas reservoir, volcano rock stratigraphic composite gas reservoir and structural lithologic gas reservoirs. The main fracture reservoir in Shengping gas field development system, including the deep faults associated, deep volcano rock controlled by fault crack accumulation model and The upper sandstone gas reservoir with fracture as the migration channel is a reservoir forming model.
