摘要
针对低渗岩性气藏非均质性强、低丰度、低产的地质特点,充分利用地质、测井、地震和测试等资料,集地质、气藏工程研究和经济评价于一体,通过多信息约束的地质建模、产能与静态地质参数关系研究和技术经济界限研究,建立了岩性气藏三维地质模型、无阻流量预测模型、开发经济界限和选区评价标准,形成了一套动静结合的低渗岩性气藏定量选区评价方法,为气田优选开发目标和实施产能建设提供了决策依据。实践表明,该方法适于低渗低产岩性气藏的选区,对于我国类似气藏的开发具有指导意义。
Lithologic gas reservoirs with low-permeability feature in higher heterogeneity and lower abundance and production. Through fully utilizing geologic, logging, seismic and test data and integrating geology and gas reservoir engineering with economic evaluation, this paper establishes 3-D geologic models, open-flow capacity forecast models, technical and economic limits of development, and criteria for selection and evaluation of development blocks on the basis of research on multi- information constrained stochastic modeling, the relationship between productivity and static geologic parameters, and technical and economic limit. Based on the above-men- tioned research, a set of dynamic-static integrated quantitative methods are presented for the evaluation and selection of development blocks in low permeability lithologic gas reservoirs to offer a scientific strategy basis for selection of gas field development targets and construction of production capacity. The field application of the methods reveals that they are suitable for selection and evaluation of low-permeability lithologic gas reservoirs and may serve as guidance for developing reservoirs with similar nature.
