【摘要】：FZ油田屬斷陷盆地典型的復(fù)雜小斷塊油田,斷層多、斷塊破碎、目的層埋藏深。隨著油田勘探開(kāi)發(fā)不斷地進(jìn)行,出現(xiàn)了許多亟待解決的試井問(wèn)題：壓力動(dòng)態(tài)監(jiān)測(cè)資料很難正常的錄取,層間干擾和井間干擾突出,嚴(yán)重地影響試井曲線形態(tài)特征,增加了資料分析的難度；不穩(wěn)定試井、穩(wěn)定試井和多井試井現(xiàn)場(chǎng)實(shí)施時(shí)涉及的地質(zhì)及工藝設(shè)計(jì)條件難以掌握,容易出現(xiàn)施工周期長(zhǎng)或錄取的資料達(dá)不到測(cè)試目的等問(wèn)題；傳統(tǒng)的試井資料解釋方法和解釋結(jié)果存在一定的錯(cuò)誤。通過(guò)研究分析試井技術(shù)和解釋評(píng)價(jià)方法,結(jié)合油田實(shí)際情況,建立了油藏儲(chǔ)集和儲(chǔ)層滲流地質(zhì)模型,將數(shù)值試井和生產(chǎn)數(shù)據(jù)分析技術(shù)成功應(yīng)用于FZ油田PD1-32斷塊NgⅣ油藏早期勘探評(píng)價(jià),分析儲(chǔ)集體有效孔隙體積、邊界距離和天然能量大小等,對(duì)后期開(kāi)發(fā)方案及時(shí)調(diào)整起到了重要指導(dǎo)作用。開(kāi)發(fā)過(guò)程中注水井壓力連續(xù)測(cè)試資料在FZ油田PD1-32斷塊Ed1油藏動(dòng)態(tài)分析中的成功應(yīng)用,直觀反映了連續(xù)測(cè)試試井資料在油藏開(kāi)發(fā)過(guò)程中的重要作用,說(shuō)明注水是必須按照動(dòng)態(tài)數(shù)據(jù)分析結(jié)果進(jìn)行調(diào)整,進(jìn)一步體現(xiàn)了連續(xù)壓力測(cè)試在油藏動(dòng)態(tài)分析中的重要性和必要性。優(yōu)化不穩(wěn)定試井測(cè)試時(shí)間,縮短施工周期,提高試井資料錄取品質(zhì),最終形成適合FZ復(fù)雜斷塊油藏的試井設(shè)計(jì)優(yōu)化、資料錄取和解釋評(píng)價(jià)技術(shù)。
[Abstract]:FZ oilfield is a typical complex small fault block oilfield in the fault depression basin, with many faults, broken fault blocks and deep burial of the target layer. With the continuous exploration and development of oil fields, there are many problems to be solved in well testing: pressure dynamic monitoring data are difficult to obtain normally, interlayer interference and inter-well interference are prominent, which seriously affect the shape characteristics of well test curve. It increases the difficulty of data analysis, unstable well test, stable well test and multi-well test field, which are difficult to master the geological and technological design conditions, and are easy to appear long operation period or the data obtained can not reach the test purpose, and so on. There are some errors in the traditional well test data interpretation method and interpretation results. Through the research and analysis of well testing technology and interpretation and evaluation methods, combined with the actual situation of oil fields, a reservoir and reservoir percolation geological model is established. The numerical well testing and production data analysis techniques have been successfully applied to the early exploration and evaluation of PD1-32 fault block Ng 鈪，
