【摘要】：隨著油田開發(fā)的深入,常規(guī)油田開發(fā)已經(jīng)不能滿足社會對油氣的需求,因此需要尋找油田開發(fā)后備潛力,低孔低滲透斷層～巖性油藏成為勘探開發(fā)增儲增產(chǎn)的重點。杏北開發(fā)區(qū)扶楊油層為低孔特低滲透斷層～巖性油藏且具有較大油氣潛力,需要開展扶楊油層的油藏評價工作。論文研究區(qū)按照物性差異可以劃分為三類潛力區(qū):Ⅰ類潛力區(qū)、Ⅱ類潛力區(qū)、Ⅲ類潛力區(qū)。為落實扶楊油層開發(fā)潛力及注水可行性,杏北開發(fā)區(qū)開展了扶楊油層Ⅰ類潛力區(qū)杏B1井區(qū)開發(fā)先導性礦場試驗,試驗表明杏北扶楊油層Ⅰ類區(qū)塊注水開發(fā)是可行的,但杏B1井區(qū)規(guī)模小,注采井網(wǎng)不夠完善,對扶楊油層Ⅱ類潛力區(qū)研究程度不夠。因此論文針對扶楊油層Ⅱ類潛力區(qū)杏A1井區(qū)進行深入研究。本文首先深化對扶揚油層地質(zhì)特征認識,形成了標準層控制下的溢岸薄層砂細分對比技術,油水層識別技術,儲層變參數(shù)解釋方法;在此基礎上,確定超前注水技術界限,優(yōu)化油水井壓裂技術,分析研究了適合于杏北扶揚油層的綜合配套技術方法,落實扶楊油層開發(fā)潛力,探索扶楊油層經(jīng)濟有效開發(fā)模式。研究結(jié)果表明,地質(zhì)分析前提下的油層動用開發(fā)技術以及超目前注水、綜合壓裂技術可以較好的指導扶楊油層開發(fā)工作,為油藏經(jīng)濟有效開發(fā)提供了成功技術經(jīng)驗,提高了開發(fā)的經(jīng)濟效益,對長垣老區(qū)扶楊油層有效開發(fā)動用也具有一定的指導意義。
[Abstract]:With the deepening of oilfield development, conventional oilfield development can no longer meet the needs of the society for oil and gas. Therefore, it is necessary to search for the reserve potential of oilfield development, and low porosity and low permeability fault ~ lithologic reservoir becomes the focus of exploration and development to increase reservoir production. Fuyang reservoir in Xingbei Development Zone is a low porosity and low permeability fault ~ lithologic reservoir with great oil and gas potential, so it is necessary to carry out reservoir evaluation of Fuyang reservoir. According to the difference of physical properties, the study area can be divided into three types of potential regions: type 鈪，
