【摘要】：MRIL—P是哈里伯顿公司生产的核磁仪器,它的主要功能是测量孔隙大小的分布,利用这一信息可以确定不受骨架影响的孔隙度、自由流体孔隙度、束缚水饱和度、粘土束缚水的孔隙度和渗透率,这些测量结果可以改进常规测井分析,确定地层是否含有油气层。它还能确定油的种类(是轻油还是重油)、气的种类等。因此深入研究核磁共振测井仪十分必要。本文紧密结合胜利油田从2003年使用P型核磁共振测井仪器所获取的测井资料、仪器使用情况以及施工经验等基础资料,通过对测井情况和仪器运行状况进行详细分析与研究,以测井信息为基础,结合核磁共振技术,阐明了核磁共振技术在评价油气层的技术优势和不足及今后的改进措施。本文从核磁测井原理出发,对核磁共振技术简单介绍,以及如何获取地层信息,该技术在油气层划分方面的技术优势,对测井储层评价具有重要作用。本文介绍了P型核磁共振的组成,对各个模块的功能、电路描述和故障排除进行了详细的分析,对技术人员在该仪器的维修和操作方面具有指导意义。最后根据施工经验和发现的问题,从核磁仪器资料解释、施工技术和操作维修能力等方面进行研究,指出该测井技术存在的问题及整改思路。为今后的核磁共振测井技术的发展和地质应用提供了指导性的作用。
[Abstract]:MRIL-P is a nuclear magnetic instrument produced by Halliburton Company. Its main function is to measure the distribution of pore size, which can be used to determine porosity, free fluid porosity and irreducible water saturation, which are not affected by skeleton. Porosity and permeability of clay bound water, which can improve conventional logging analysis, It can also determine the types of oil (light oil or heavy oil, gas, etc.). Therefore, it is very necessary to study nuclear magnetic resonance logging tool. This paper closely combined with Shengli oil field from 2003 to use P. The logging data obtained by the nuclear magnetic resonance logging tool, Through the detailed analysis and study of the logging situation and the operation condition of the tool, the paper combines the nuclear magnetic resonance technology with the logging information, which is based on the basic data of the use of the tool and the construction experience. The advantages and disadvantages of nuclear magnetic resonance (NMR) technology in evaluating oil and gas reservoirs and the improvement measures in the future are expounded. Based on the principle of nuclear magnetic logging, the nuclear magnetic resonance (NMR) technique is briefly introduced, and how to obtain formation information is introduced. The technical advantage of this technique in oil and gas reservoir division plays an important role in logging reservoir evaluation. In this paper, the composition of P-NMR is introduced, and the function, circuit description and troubleshooting of each module are analyzed in detail. It is of guiding significance for technicians in the maintenance and operation of the instrument. Finally, according to the construction experience and the problems found, the paper studies the data interpretation of nuclear magnetic instrument, construction technology and operation maintenance ability, etc. The problems existing in the logging technology and the ideas for improvement are pointed out, which provides guidance for the development and geological application of nuclear magnetic resonance logging technology in the future.
