【摘要】：為指導(dǎo)SAGD開發(fā)區(qū)油氣開發(fā)及認(rèn)識(shí)剩余油分布規(guī)律,應(yīng)用高分辨率層序地層學(xué)方法,綜合巖心、測(cè)井及地震資料,研究了遼河坳陷曙一區(qū)杜84塊SAGD開發(fā)區(qū)館陶組沖積扇儲(chǔ)層層序分布模式。結(jié)果表明:館陶組地層可劃分為1個(gè)長(zhǎng)期旋回,4個(gè)中期旋回及10個(gè)短期旋回,其中短期旋回按可容納空間大小可劃分為Ⅰ,Ⅱ,Ⅲ,Ⅳ和Ⅴ型;以中期旋回為等時(shí)單元,垂向上等時(shí)單元內(nèi)形成的短期旋回類型與其在中期旋回中的位置有關(guān),而中期旋回的保存程度又取決于其在長(zhǎng)期旋回中的位置,側(cè)向上等時(shí)單元內(nèi)形成的短期旋回的可容納空間順物源方向逐漸增大。杜84塊SAGD開發(fā)區(qū)館陶組短期旋回類型與儲(chǔ)層物性存在對(duì)應(yīng)關(guān)系,較優(yōu)的儲(chǔ)層位置多處于中期基準(zhǔn)面上升早中期的沖積扇扇根與扇中交界處或扇中前緣。
[Abstract]:In order to guide the development of oil and gas in SAGD development zone and to understand the distribution law of remaining oil, the high resolution sequence stratigraphy method is used to synthesize core, well logging and seismic data. The stratigraphic sequence distribution model of alluvial fan reservoir of Guantao formation of SAGD development zone in Shu1 area of Liaohe depression is studied. The results show that the strata of Guantao formation can be divided into 1 long term cycle, 4 intermediate cycle and 10 short term cycles, in which the short term cycles can be divided into 鈪，
