【摘要】：目前,基于套管井評價(jià)剩余油飽和度的主要方法有中子壽命測井、碳氧比測井、脈沖中子-中子測井、過套管電阻率測井等。然而,使用這些方法進(jìn)行解釋應(yīng)用時(shí),還需結(jié)合鄰井的注水情況,以及其他資料等,以確定套管外的水淹層位為主,定量地確定儲層剩余油飽和度。因此,這些方法都有其適用性和局限性。本文從查閱關(guān)于剩余油探測評價(jià)方法的資料入手,研究基于套管井評價(jià)剩余油飽和度方法的適用性和局限性,提出了智能套管測井系統(tǒng),可以有效的改善上述方法的局限性。本文將詳細(xì)講述智能套管的設(shè)計(jì)構(gòu)架、智能套管測井原理與方法、智能套管測井儀器框架設(shè)計(jì)；重點(diǎn)介紹基于COMSOL Multiphysics軟件對智能套管測井系統(tǒng)的仿真、穩(wěn)定電流場理論、分析智能套管測井系統(tǒng)在電場中的分布響應(yīng),以及測量地層視電阻率等,以仿真實(shí)驗(yàn)論證了智能套管測井系統(tǒng)優(yōu)越性,為進(jìn)一步研究智能套管測井系統(tǒng)提供了重要的理論依據(jù)。
[Abstract]:At present, the main methods for evaluating residual oil saturation based on casing wells include neutron lifetime logging, carbon-oxygen ratio logging, pulse neutron neutron logging, casing resistivity logging and so on. However, when these methods are used for interpretation and application, it is necessary to combine the water injection situation of adjacent wells, as well as other data, in order to determine the water-flooded layer outside the casing and quantitatively determine the remaining oil saturation of the reservoir. Therefore, these methods have their applicability and limitations. In this paper, the applicability and limitation of the method for evaluating residual oil saturation based on casing wells are studied by consulting the data of residual oil exploration and evaluation methods, and an intelligent casing logging system is proposed, which can effectively improve the limitations of the above methods. In this paper, the design framework of intelligent casing, the principle and method of intelligent casing logging, the framework design of intelligent casing logging tool, the simulation of intelligent casing logging system based on COMSOL Multiphysics software, and the theory of stabilizing current field are introduced in detail. The distribution response of intelligent casing logging system in electric field and the measurement of formation apparent resistivity are analyzed. The superiority of intelligent casing logging system is demonstrated by simulation experiments, which provides an important theoretical basis for further research on intelligent casing logging system.
