【摘要】：随着吉林油田勘探开发不断深入,所发现的油气藏越来越复杂。深层天然气储层已成为德惠地区重点勘探开发对象。埋藏深、岩相多样复杂、流体性质特殊等特点致使德惠深层天然气储层在利用常规测井资料进行岩性、储层参数测井解释模型、储层流体类型判别和产能预测等方面存在难点。油田实际勘探开发迫切需要对这些问题开展技术研究和攻关,以达到通过测井资料评价解释,提高流体性质识别率的预期目标。为了更好的落实德惠断陷深层天然气的储量,本文首先分区域、层位、岩性建立地质模型,采用直方图和交会图法对测井曲线进行质量评价和标准化,建立相应的岩性识别样本集,给出岩性识别标准;其次,在“四性”关系分析基础上分区域、分层位建立泥质含量、孔隙度、含水饱和度等储层参数测井解释模型,参数精度达到生产要求;第三,在构建合成参数的基础上建立流体识别方法及标准,有效提高了解释符合率,为潜力层段的合理提出奠定了基础。本文研究的主要目的是建立有效的流体识别测井解释图版和标准,建立适合的储层参数测井解释模型,提高德惠断陷流体识别测井解释符合率,为研究区域储量评估提供基础准备和技术保障。
[Abstract]:With the deepening of exploration and development in Jilin Oilfield, the oil and gas reservoirs found are becoming more and more complex. Deep gas reservoir has become a key exploration and development object in Dehui area. The characteristics of deep burial, complicated lithofacies and special fluid properties make it difficult for Dehui deep gas reservoir to make use of conventional logging data to carry out lithology, log interpretation model of reservoir parameters, type discrimination of reservoir fluid and prediction of productivity. In order to improve the recognition rate of fluid properties, it is urgent for the actual exploration and development of oil fields to carry out technical research and tackle the key problems in order to improve the identification rate of fluid properties through the evaluation and interpretation of logging data. In order to realize the reserves of deep gas in Dehui fault depression better, this paper firstly establishes geological model by region, horizon and lithology, and uses histogram and cross plot method to evaluate and standardize the quality of logging curve. The corresponding lithology identification sample set is established, and the lithologic identification standard is given. Secondly, the logging interpretation model of reservoir parameters such as muddy content, porosity and water saturation is established on the basis of "four properties" relationship analysis. Third, the method and standard of fluid identification are established on the basis of constructing synthetic parameters, which can effectively improve the interpretation coincidence rate and lay a foundation for the reasonable proposal of potential layer. The main purpose of this paper is to establish an effective interpretation chart and standard for fluid identification logging, to establish a suitable logging interpretation model for reservoir parameters, and to improve the interpretation coincidence rate of fluid identification logging in Dehui fault depression. To provide basic preparation and technical support for regional reserve assessment.
