摘要 在油田注水开发过程中,为保障选择水淹程度低和含油丰度高的层段进行射孔开发,开展了地化录井技术在吉林油田水平开发井的应用研究。针对水淹程度评价和含油丰度分析在开发井解释评价中重要作用,从岩石热解参数S_0、S_1、S_2和热解气相色谱谱图形态以及正构烷烃含量入手,研究了地化录井参数在吉林油田注水开发过程中的变化规律,建立了开发井油气层含油丰度和水淹程度判别标准。应用实例表明,在水平井地质导向和投产射孔井段的选择中应用效果明显,得到了甲方的高度评价和重视。通过在开发井中的广泛应用,不但提高了水平井地质导向的成功率,还增强了优选投产射孔井段的能力。 During the water injection development in the oilfield, in order to ensure that the intervals with lower water floo- ded degree and higher oil bearing abundance can be chosen to conduct perforation development,the application study for geochemical logging technology was carried out in hori- zontal development wells in Jilin Oilfield.In accordance with the significant functions of water flooded evaluation and oil bearing abundance analysis in the interpretation and evaluation in development wells,and in point of pyrolysis parameters of S_0,S_1,S_2,pyrolysis gas chromatographic spectrum form and n-alkane content,the author studied the changing rule of geochemical logging parameters during wa- ter injection development in Jilin Oilfield,and established the distinguishing criteria for oil bearing abundance and wa- ter flooded degree in oil and gas layers of development wells.It was showed by practices that the obvious applica tion results were obtained in the geologic orientation of hor- izontal wells and the selection of perforation intervals in production wells,and the technology was highly appreciated and paid attention by Party A.By the widely application in development wells,not only was the successful rate in hori- zontal geologic orientation increased,but also was the abili- ty of optimum selection for production perforation interval enhanced.
