【摘要】：大慶榆樹(shù)林油田扶楊油層沉積過(guò)程發(fā)育多期河道砂體,其呈狹窄條帶狀相互疊置且區(qū)域相變快,這些復(fù)雜的沉積特征制約著油田的開(kāi)發(fā)。如何進(jìn)行儲(chǔ)層預(yù)測(cè)、提高預(yù)測(cè)精度客觀合理的確定砂體分布一直是在科研生產(chǎn)中面臨的主要問(wèn)題,直接影響著油田下一部的勘探開(kāi)發(fā)。本文在對(duì)樹(shù)123區(qū)塊沉積、構(gòu)造分析的基礎(chǔ)上,應(yīng)用地震屬性提取、地質(zhì)統(tǒng)計(jì)學(xué)反演對(duì)扶楊油層進(jìn)行砂體級(jí)別的儲(chǔ)層預(yù)測(cè)。得到成果和認(rèn)識(shí)如下:通過(guò)開(kāi)展井震聯(lián)合統(tǒng)層,建立等時(shí)地層格架,扶楊油層自上到下分別劃分了6個(gè)油層組,即FⅠ、FⅡ、FⅢ、YⅠ、YⅡ、YⅢ組,38個(gè)小層。樹(shù)123區(qū)塊扶楊油層存在“東高西低,北高南低”的構(gòu)造形式。同時(shí)研究區(qū)整體斷層發(fā)育,目的層內(nèi)部從下至上,斷裂繼承性發(fā)育的較好,斷層系內(nèi)大型斷層以南北向發(fā)育為主,小型斷層以東西向?yàn)橹�。�?duì)研究區(qū)進(jìn)行沉積相分析認(rèn)識(shí)到,物源主要來(lái)源于北東方向,發(fā)育河流-三角洲體系。密井網(wǎng)區(qū)利用測(cè)井?dāng)?shù)據(jù),稀井區(qū)利用地震儲(chǔ)層預(yù)測(cè)結(jié)果,對(duì)研究區(qū)平面沉積微相展布進(jìn)行研究。最終在沉積相約束下,利用反演結(jié)果,對(duì)含油小層的砂體進(jìn)行刻畫(huà)。認(rèn)為在構(gòu)造及沉積背景的影響下,研究區(qū)砂體多呈南北、北東向條帶狀或塊狀展布。其分布特征為尋找油氣富集有利區(qū)提供有利依據(jù)。
[Abstract]:The depositional process of Fuyang reservoir in Daqing Yushulin Oilfield is characterized by multi-stage channel sand body, which is a narrow strip superimposed on each other, and the regional phase transition is fast. These complex sedimentary characteristics restrict the development of the oil field.How to predict reservoir and determine the distribution of sand body objectively and reasonably is always the main problem in scientific research and production, which directly affects the exploration and development of the next oil field.On the basis of sedimentary and structural analysis of block Shu123, this paper uses seismic attribute extraction and geostatistical inversion to predict reservoir level of sand body in Fuyang oil reservoir.The results and understandings are as follows: through the development of the combined well and earthquake formation and the establishment of isochronous stratigraphic framework, Fuyang oil layer is divided into 6 reservoirs from top to bottom, namely F 鈪，
