Microvisual pore structure is an important factor of influencing the degree of gas reservoir water-bound plugging and the influence of pore structure on gas reservoir water-bound plugging was studied by applying the microvisual model experimental technique. This technique means that the pore network model of rock porous media can be set up by applying the analogy or dummy simulation method; and by taking the model as an object of study, the concrete circumstances of the fluid flowing in porous media and of the interaction between fluids and between the fluids and the solid surfaces were observed by the authors. There are four models, i.e. pearl-clamped model, capillary network model, pore network model and sandstone pore model, each having its different merits and demerits. The pore network model, which not only can reflect the formation features actually but also is convenient to observe and obtain a clear image, was selected for the experimental study. In the process of experiment, the details of fluid flowing in the analog pore system were directly observed with the aid of micro-device and recorded by applying video-recording technique, in addition, the related data were tested by use of up-to-date testing techniques. Various pore network models used for different pore structures were designed by applying visualized micro-experimental techniques and as the gas reservoir water-bound plugging happened under the conditions of different structures, two phase(gas-water) micro distribution characteristics were studies and the law of the influence of pore structure on the gas reservoir water-bound plugging were found out according to these models.

微观孔隙结构是影响气藏水束缚堵塞严重程度的一个重要因素 ,文章通过微观模型实验技术研究了孔隙结构对气藏水束缚堵塞的影响。微观模型实验技术是指通过相似模拟或仿真模拟的方法制作岩石多孔介质的孔隙网络模型 ,并以此为研究对象 ,观测流体在多孔介质中流动的具体情况 ,以及流体之间、流体与固体表面之间的相互作用规律等问题。模型大致有夹珠模型、毛管网络模型、孔隙网络模型和砂岩孔隙模型 ,基于这四种微观模型各自具有不同的优点和缺点 ,文章选用既能比较真实地反映地层特征 ,又便于观察 ,能得到清晰图像的孔隙网络模型进行实验研究。实验过程中 ,借助显微装备直接观测了模型孔隙体系内的流动细节 ,并利用录像技术记录了这些细节 ,用现代测试技术测试有关数据。文章利用微观可视化实验技术 ,设计了不同孔隙结构的孔隙网络模型 ,研究了不同孔隙结构条件下气藏水束缚堵塞发生时气水两相微观分布特征 ,得出了孔隙结构对气藏水束缚堵塞的影响规律。

Spin relaxation time measurement is one of the most important applications of NMR technology. Relaxation parameters derived from NMR measurements provide structural and dynamic information of molecules. Applications in porous media further show that the distribution of relaxation time can be use to determine pore size,irreducible water saturation,and formation permeability etc. In this paper we described three relaxation mechanisms and how they can be used to obtain information about rock porous media....

Spin relaxation time measurement is one of the most important applications of NMR technology. Relaxation parameters derived from NMR measurements provide structural and dynamic information of molecules. Applications in porous media further show that the distribution of relaxation time can be use to determine pore size,irreducible water saturation,and formation permeability etc. In this paper we described three relaxation mechanisms and how they can be used to obtain information about rock porous media. Bulk relaxation time of free-fluid is used to differentiate the type of fluids and the quality of oil,surface relaxation distribution provides information of pore size and capillary bonding,and diffusion coefficient improves the capability of fluid typing and pore geometry determination. We also summarized various methods for measuring relaxation times and self-diffusion coefficient,as well as their distributions.

弛豫时间是核磁共振研究中的一个重要参数,岩心孔隙介质流体的弛豫过程是自由流体弛豫机制、表面弛豫机制和流体的扩散弛豫机制共同作用的结果,它包含了丰富的孔隙和流体本身的信息.弛豫时间和自扩散系数的测量及对弛豫时间的分析是核磁共振技术应用于岩心分析和石油勘测的重要内容.
