【摘要】：近年来,辽河油田面临着有效勘探领域减小、勘探程度高、勘探目标复杂的勘探形势,扩大老区勘探领域迫在眉睫。经过多年的持续勘探开发,在S区块沙四下段砂砾岩体已经有多口工业油气流井,勘探前景非常广阔。为了扩大勘探成果,确定了在老区已有勘探成果基础上向西斜坡北边扩展到勘探思路。但是目前勘探中存在岩性认识不清、小层划分困难、单井有效储层难以划分以及四性关系认识不清等问题。2015年已经初步建立了S区块沙四下段砂砾岩体岩性识别、储层划分标准、参数计算模型和储层工程品质计算模型,为研究工作打下了坚实基础。本文应用测井的手段,在岩心联合描述及岩矿实验的基础上,充分利用已钻探井资料,开展岩性二次解释,对单井岩性进行重新划分;此外在岩性二次解释的基础上,综合试油、试采、录井及其它地质资料,对储层进行二次解释、储层参数研究、测井相的划分及储层工程品质研究,为整个勘探提供技术支持。
[Abstract]:In recent years, Liaohe Oilfield is faced with the exploration situation of decreasing effective exploration field, high exploration degree and complex exploration target. It is urgent to expand the exploration field in old area. There are already many industrial oil gas flow wells in the sand gravel rock of the fourth member of S block, and the prospect of exploration is very broad. In order to expand the exploration results, It is determined that the exploration idea is extended to the north of the western slope on the basis of the existing exploration results in the old area. However, at present, there is a lack of clear understanding of lithology in exploration, and it is difficult to divide small beds. In 2015, the lithology identification, reservoir classification standard, parameter calculation model and reservoir engineering quality calculation model of the sand-gravel rock mass in the lower member of Sha-4 formation in S block have been preliminarily established. In this paper, based on the core joint description and rock and mineral experiments, the lithology secondary interpretation is carried out, and the lithology of single well is reclassified by using the data of drilling wells. In addition, on the basis of secondary interpretation of lithology, combined with oil test, production test, logging and other geological data, the secondary interpretation of reservoir, the study of reservoir parameters, the division of logging facies and the study of reservoir engineering quality provide technical support for the whole exploration.
