【摘要】：為了系統(tǒng)認(rèn)識榆樹林油田尚9區(qū)塊扶楊油層主力砂體發(fā)育及分布特征,本文利用鉆井資料、測井資料、三維地震資料以及開發(fā)試油資料,首先通過地層精細(xì)劃分對比和井震結(jié)合的方法劃分了研究區(qū)扶楊油層沉積時(shí)間單元,建立了成因單砂體級的地層格架;其次在取心井相分析及測井微相模式建立等基礎(chǔ)上,勾繪了各沉積時(shí)間單元的平面沉積微相,并分析了其垂向沉積相演化特征;最后,通過構(gòu)型參數(shù)的精細(xì)選取,建立了研究區(qū)典型沉積單元FⅠ71砂體內(nèi)部建筑結(jié)構(gòu),并利用沉積微相控的多參數(shù)綜合法,勾繪了研究區(qū)9各重點(diǎn)層位儲層流動單元。認(rèn)為研究區(qū)扶楊油層可劃分為75個(gè)沉積單元;發(fā)育三角洲分流平原亞相和前緣亞相,分流平原亞相主要分為河道主體、分流河道、廢棄河道、一類溢岸砂、二類溢岸砂及分流間灣微相,三角洲前緣亞相主要分為水下分流河道、席狀砂主體、席狀砂、席內(nèi)緣、席外緣及水下分流間微相;劃分出A、B、C、D、E1、E2等6類流動單元,其中A類是儲集性能最好的流動單元。通過本文的研究為研究區(qū)扶楊油層主力油層后續(xù)的開發(fā)部署和剩余油挖潛提供可靠依據(jù)。
[Abstract]:In order to systematically understand the development and distribution characteristics of the main sand bodies of Fuyang reservoir in Shang9 block of Yushulin Oilfield, this paper uses drilling data, logging data, 3D seismic data and development test data. Firstly, the sedimentary time unit of Fuyang oil layer in the study area is divided by the method of fine stratigraphic division and correlation with well shock, and the stratigraphic framework of single sand body level is established, secondly, on the basis of coring well facies analysis and logging microfacies model, etc. The planar sedimentary microfacies of each sedimentary time unit are plotted, and the evolution characteristics of vertical sedimentary facies are analyzed. Finally, through the fine selection of configuration parameters, the building structure of the typical sedimentary unit F 鈪，
