摘要
升平油田位于松辽盆地中央坳陷区三肇凹陷徐家围子鼻状构造向南倾没端延伸部位,主要开发的目的层为葡萄花油层。经过多年的钻井开发以及井网加密调整、注采系统调整和注水结构调整,储层发育相对较好的区块基本已经进入开发中后期,进一步开发的潜力越来越小,在老油田内寻找新的有利含油区的难度越来越大。升平油田北部地区存在着一个空白区,该区井控程度低,葡萄花油层储层发育差,已完钻井的葡萄花和扶余油层主要发育水层和干层,要进一步勘探开发难度较大。本文主要介绍储层含油特征研究的思路,通过该研究有望在升平油田北部空白区找到有利含油区块。
Shenping oilfield is situated in south end extension of Xujiaweizi nosing structure,Sanzhao sag,central depression,Songliao basin,with Putaohua formation to be the major reservoir.After a long term drilling development,injection-extraction adjustment and water-injection structural adjustment,those blocks with good reservoir are now in late development stage with a little potential.The northern Shenping basin is a virgin,low extent in drilling and poor in Putaohua reservoir,largely occurring as water layer or dry layer,as well as Fuyu reservoir.It is difficult to develop this block.This paper studies the oil-bearing features with results that it is of potential to find oil-bearing blocks in the northern Shenping basin.
