【摘要】：近年来沈阳采油厂大民屯潜山水平井在开发过程中遇到各种油气显示与产能非相关的问题。通过探索和总结相应的录井解释评价方法,形成油气显示与产能二者之间的规律性认识。为甲方勘探和开发以及指导今后的录井工作提供可靠的依据,为配产方案编制寻找有利井网或优化油气层开发层系,延长油井投产周期,提高单井产油量提供支持。本文通过对现场岩屑、气测、地化、定量荧光等录井技术进行研究,综合分析各方法的应用效果,对各方法进行有机结合;通过定量荧光、地化等参数及谱图区分岩屑显示及钻井液污染情况,通过元素分析、岩心实物标准定样,DC指数参考等方法对潜山岩性进行辨别,对储层类别进行区分,效果良好。研究了静水压力坏境下气测值的变化情况,提出了“全烃恢复值--钻时”交汇解释方法,将物性、含油性创新性的有机结合,解决了过平衡钻井消弱显示带来的解释难题。本文提出了钻时,钻速曲线重叠交汇法,比以往录井单纯的钻时,全烃评价储层的方法全面,采用了曲线重叠交汇技术,加入DCS指数来识别潜山刚性体的可钻性的变化,辅助峰基比来确认含油性。
[Abstract]:In recent years, the horizontal well of Damingtun buried hill in Shenyang oil production plant has encountered various problems of oil and gas display not related to productivity in the course of development. By exploring and summarizing the corresponding mud logging interpretation and evaluation methods, Forming a regular understanding between oil and gas display and productivity, providing a reliable basis for Party A's exploration and development and guiding future logging work, searching for favorable well pattern for production planning or optimizing the development layer system of oil and gas reservoir, and providing a reliable basis for Party A's exploration and development as well as guiding the logging work in the future. In this paper, the mud logging techniques such as cuttings, gas logging, geochemistry and quantitative fluorescence are studied, the application effect of each method is analyzed synthetically, and the organic combination of each method is carried out. The lithology of buried hill is distinguished by quantitative fluorescence, geochemistry and spectral diagram. The lithology of buried hill is distinguished by element analysis, reference of core standard sample and DC index, and reservoir classification. The effect is good. The change of gas measurement value under the bad hydrostatic pressure is studied, and the method of "total hydrocarbon recovery value-drilling time" is put forward, which combines the organic combination of physical property and oil content innovation. In this paper, the overlapping intersection method of drilling velocity curve is proposed, which is more comprehensive than the simple drilling method in mud logging, and the method of curve overlapping intersection is adopted. The DCS index is added to identify the drillability of the buried hill rigid body, and the ratio of peak to base is used to confirm the oil content.
