CL气田登娄库组为深层低渗致密砂岩储层,开发难度大。常规单一的气藏描述方法不能满足要求,为此本文结合测井、物探及地质,应用确定性和随机性理论,分别建立边界并模拟内部非均质性,在相控基础上利用序贯高斯算法模拟储层物性的空间分布,综合评价气藏地质特征。通过相控建模技术的应用,有效地描述了构造、断层、微相、物性及储量等气藏特征,成功实现深层致密气藏的经济有效开发,为准确评价储层性质及开发潜力提供可靠依据。
The Denglouku Formation in the CL gas field is a deep, low-permeability, tight sandstone reservoir that is difficult to develop. Conventional single description of gas reservoirs can not meet the requirements. Therefore, in this paper, based on well logging, geophysics and geology, application of certainty and stochastic theory, we establish boundaries and simulate internal heterogeneity respectively. By using sequential Gaussian The algorithm simulates the spatial distribution of reservoir physical properties and comprehensively evaluates the geological characteristics of gas reservoirs. Through the application of phased-image modeling technology, the characteristics of gas reservoirs such as tectonics, faults, microfacies, physical properties and reserves are effectively described, and the economical and effective exploitation of deep-seated gas reservoirs is successfully achieved, providing reliable assessment of reservoir properties and development potentials in accordance with.
