【摘要】：葉三撥油田主體位于南皮縣段六撥鄉(xiāng),區(qū)域構(gòu)造位置位于黃驊坳陷南區(qū)滄東裙邊構(gòu)造帶的舍女寺斷鼻南翼,勘探面積123km2。該地區(qū)北、東分別與舍女寺、段六撥油田相接,南鄰南皮凹陷,西為滄縣隆起,東北部通過(guò)孔東大斷層與王官屯油田相連,構(gòu)造位置相當(dāng)有利。經(jīng)多年的勘探開發(fā)證實(shí)其油氣資源豐富,成藏條件優(yōu)越,鉆探顯示孔店組-沙河街組中發(fā)育多套含油層系。隨著增產(chǎn)增收的需要和對(duì)油藏的進(jìn)一步潛挖技術(shù)的提高,研究區(qū)進(jìn)入高含注水開發(fā)的階段,同時(shí)面臨如下問(wèn)題,一是研究區(qū)域內(nèi)發(fā)育較多斷層,對(duì)油藏控制因素影響較大,二是研究區(qū)內(nèi)含油層系較多,并由于斷層控制因素和中深層埋深因素而產(chǎn)生許多隱蔽性油藏與斷塊油藏,三是研究區(qū)內(nèi)巖性發(fā)育多樣性,從孔店組到沙河街組發(fā)育各種不同巖性,其巖相與沉積相演化規(guī)律較繁雜,但同時(shí)生烴巖與有效儲(chǔ)層厚度較大,分布廣,具有很好的開發(fā)前景。四是基礎(chǔ)地質(zhì)研究程度低,在此前缺乏詳細(xì)的層序地層劃分與沉積體系域劃分研究。根據(jù)前人資料的統(tǒng)計(jì)結(jié)果,目前葉三撥研究區(qū)內(nèi)地震資料比較豐富完整,并覆蓋整個(gè)研究區(qū)域309km2左右,研究區(qū)內(nèi)井位數(shù)150口左右,其中探井大約有40口。油田內(nèi)部多開發(fā)井,井控較好,測(cè)井?dāng)?shù)據(jù)與巖性數(shù)據(jù)較全,外部探井較多,資料較齊。共有鉆取芯井30口,取心總進(jìn)尺977.21m,巖心總長(zhǎng)905.98m,總收獲率為92.7%。在此之前,(李艷偉,2013)對(duì)研究區(qū)孔二段做過(guò)沉積相研究,(馬少妍,2013)對(duì)于研究區(qū)做過(guò)有利圈閉綜合評(píng)價(jià),但是僅限于開發(fā)小層對(duì)比模式的研究.本次論文運(yùn)用層序地層學(xué),地震地層學(xué),沉積巖石學(xué)與巖相古地理基本理論指導(dǎo),通過(guò)地震時(shí)間切片(地震剖面)響應(yīng)特征,地質(zhì)巖性資料與優(yōu)選測(cè)井?dāng)?shù)據(jù),在對(duì)應(yīng)層劃分的控制基礎(chǔ)上,結(jié)合開發(fā)地質(zhì)的小層對(duì)比原則與層序地層劃分標(biāo)準(zhǔn),區(qū)分和劃分研究區(qū)高精度等時(shí)小層對(duì)比-層序地層界面。將孔店組自下而上劃分出1個(gè)超長(zhǎng)期(Ⅱ級(jí))旋回(SSC1)、4個(gè)長(zhǎng)期(Ⅲ級(jí))旋回(LSC1-LSC4)、12個(gè)中期(Ⅳ級(jí))旋回(MSC1-MSC12),沙河街組自下而上劃分出1個(gè)超長(zhǎng)期(Ⅱ級(jí))旋回(SSC2)、3個(gè)長(zhǎng)期(Ⅲ級(jí))旋回(LSC5-LSC7)、8個(gè)中期(Ⅳ級(jí))旋回(MSC13-MSC20),及相應(yīng)級(jí)別體系域。在研究區(qū)層序地層和沉積相研究的基礎(chǔ)上,建立了葉三撥地區(qū)孔店組-沙河街組的IV級(jí)層序地層格架。在層序格架內(nèi),以巖性資料為依據(jù),結(jié)合測(cè)井曲線響應(yīng)特征及地震響應(yīng)特征分析資料,確立單井微相標(biāo)志,明確單井沉積微相類型。并繪制了連井地層及沉積微相對(duì)比剖面圖及砂體厚度等值線平面圖,砂地比等值線圖和沉積微相平面圖,在IV級(jí)層序地層格架內(nèi)標(biāo)定并描述了單砂體的分布特征以及沉積相演化特征。同時(shí)分析層序地層與沉積相控制下的有效儲(chǔ)層巖性分布,為研究區(qū)進(jìn)一步的開發(fā)生產(chǎn)提供基礎(chǔ)地質(zhì)技術(shù)支持。
[Abstract]:The main body of Yesanpo Oilfield is located in Liupaoxiang, Nanpi County, and the regional structure is located in the south wing of Shanusi fault nose of Cangdong skirt structural belt in the southern part of Huanghua depression. The exploration area is 123km2. The north and east of the area are connected with the Shenusi oil field respectively, the south is adjacent to the Nanpi depression, the west is Cangxian uplift, and the northeast is connected with the Wangguantun oil field through the Kongdong fault, the tectonic position is quite favorable. After many years of exploration and development, it has been proved that it is rich in oil and gas resources, and its reservoir forming conditions are superior. The drilling shows that there are many sets of oil-bearing strata developed in Kongdian formation and Shahejie formation. With the need of increasing production and income and the improvement of further subsurface digging technology for reservoirs, the research area has entered the stage of high content water injection development. At the same time, it faces the following problems: first, more faults are developed in the study area, which have a great influence on reservoir control factors. Second, there are many oil-bearing strata in the study area, and many hidden reservoirs and fault-block reservoirs are produced because of fault control factors and buried depth factors in the middle and deep layers. Third, the development diversity of lithology in the study area. From Kongdian formation to Shahejie formation, various lithologies are developed. The evolution rules of lithofacies and sedimentary facies are complicated, but at the same time hydrocarbon generating rocks and effective reservoirs are thicker and widely distributed, so they have a good development prospect. Fourth, the basic geological research degree is low, lack of detailed sequence stratigraphic division and sedimentary system tracts division research before. According to the statistical results of previous data, the seismic data in Yesanpo study area is relatively rich and complete, covering the whole research area 309km2 or so. The number of wells in the study area is about 150, of which there are about 40 exploration wells. The well control is better, the logging data and lithologic data are complete, and the external exploration wells are more uniform. A total of 30 coring wells were drilled, with a total coring scale of 977.21 m, a total core length of 905.98 m and a total yield rate of 92.7 m. Prior to this, Li Yanwei (Li Yanwei 2013) has done sedimentary facies research on the second member of the pore in the study area (Ma Shaoyan 2013) has made a comprehensive evaluation of favorable traps for the study area, but it is only limited to the study of the development of a small layer correlation model. Based on the basic theories of sequence stratigraphy, seismostratigraphy, sedimentary petrology and lithofacies and paleogeography, this paper uses seismic time slice (seismic section) response characteristics, geological lithology data and selected logging data. On the basis of the control of corresponding stratigraphic division, combined with the correlation principle of development geology and the standard of sequence stratigraphic division, the high precision isochronous small layer correlation and sequence stratigraphic interface of the study area are distinguished and divided. The Kongdian formation was divided into one super-long (鈪，
