【摘要】：松南氣田屬于致密火山巖氣藏。根據(jù)松南氣田大量火山巖氣井產(chǎn)能測(cè)試數(shù)據(jù),以氣井產(chǎn)能為依據(jù)進(jìn)行分類,并分別統(tǒng)計(jì)它們的巖性、密度、聲波時(shí)差、孔隙度、滲透率、阻抗范圍,建立松南氣田致密火山巖儲(chǔ)層的分類標(biāo)準(zhǔn)。在此基礎(chǔ)上,利用巖心、鑄體薄片和掃描電鏡,識(shí)別不同類型儲(chǔ)層的宏觀、微觀孔隙-裂縫組合特征,研究不同類型火山巖儲(chǔ)層的孔隙-裂縫發(fā)育模式。并進(jìn)一步根據(jù)儲(chǔ)層類型、地震反演孔滲參數(shù),探討了大型火山巖氣藏潛力目標(biāo)區(qū)優(yōu)選方法。松南氣田火山巖儲(chǔ)層可分為I類未措施高產(chǎn)、II類措施后高產(chǎn)、Ⅲ類未措施不出氣、Ⅳ類致密層四類。四類儲(chǔ)層對(duì)應(yīng)四種儲(chǔ)層發(fā)育模式:I類儲(chǔ)層為原生孔+微裂縫型,II類儲(chǔ)層為次生孔+微裂縫型,Ⅲ類儲(chǔ)層為原生孔+構(gòu)造裂縫型,Ⅳ類儲(chǔ)層為次生孔+構(gòu)造裂縫型。潛力優(yōu)選研究表明,YS1斷塊2號(hào)、3號(hào)目標(biāo)體具有一定的開(kāi)發(fā)潛力。儲(chǔ)層分類更適合于本區(qū)致密儲(chǔ)層的實(shí)際生產(chǎn)情況。
[Abstract]:Songnan gas field belongs to tight volcanic gas reservoir. According to the productivity test data of a large number of volcanic gas wells in Songnan gas field, the gas well productivity is classified, and their lithology, density, acoustic moveout, porosity, permeability, impedance range are counted respectively. The classification standard of dense volcanic reservoir in Songnan gas field is established. On this basis, the pore fracture pattern of different types of volcanic rock reservoirs is studied by means of core, casting sheet and scanning electron microscope to identify the macro and micro pore fracture assemblage characteristics of different types of reservoirs. Furthermore, according to reservoir types and seismic inversion of pore and permeability parameters, the optimization method for potential target areas of large volcanic gas reservoirs is discussed. The volcanic rock reservoirs in Songnan gas field can be divided into four types: type I without measures and type II without measures, type III without measures without gas outgassing, class 鈪，
