【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(huì)對(duì)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(chǔ)增產(chǎn)的重點(diǎn)。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(píng)價(jià)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(shí)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(dǎo)性礦場(chǎng)試驗(yàn),試驗(yàn)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(duì)扶楊油層Ⅱ類潛力區(qū)研究程度不夠。因此論文針對(duì)扶楊油層Ⅱ類潛力區(qū)杏A1井區(qū)進(jìn)行深入研究。本文首先深化對(duì)扶揚(yáng)油層地質(zhì)特征認(rèn)識(shí),形成了標(biāo)準(zhǔn)層控制下的溢岸薄層砂細(xì)分對(duì)比技術(shù),油水層識(shí)別技術(shù),儲(chǔ)層變參數(shù)解釋方法;在此基礎(chǔ)上,確定超前注水技術(shù)界限,優(yōu)化油水井壓裂技術(shù),分析研究了適合于杏北扶揚(yáng)油層的綜合配套技術(shù)方法,落實(shí)扶楊油層開發(fā)潛力,探索扶楊油層經(jīng)濟(jì)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(dòng)用開發(fā)技術(shù)以及超目前注水、綜合壓裂技術(shù)可以較好的指導(dǎo)扶楊油層開發(fā)工作,為油藏經(jīng)濟(jì)有效開發(fā)提供了成功技術(shù)經(jīng)驗(yàn),提高了開發(fā)的經(jīng)濟(jì)效益,對(duì)長(zhǎng)垣老區(qū)扶楊油層有效開發(fā)動(dòng)用也具有一定的指導(dǎo)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，
