榆树林油田尚12区块扶杨油层录井综合解释标准

The mud logging comprehensive interpretation standards of Fuyang oil zones in Shang 12 Block of Yushulin Oilfield

榆树林油田尚12区块扶杨油层断层发育,油藏类型复杂,流体识别相对困难,给油气水解释带来一定难度,造成解释失误偏多。针对这一状况,对该区资料进行全面复查,经过系统的分析研究,总结了岩心、岩屑、井壁取心实物的含油颜色、饱满程度、油气味、物性、系列对比以及气相色谱、镜下荧光等特点。将岩石热解参数与测井参数有机结合,建立了尚12区块扶杨油层解释图板,完善了解释标准,改变了传统的解释方法,较好地解决了疑难储集层流体性质识别问题,达到了精细解释的目的。通过SH12-2井、SH4-102-56井的应用实例,对该方法的应用效果进行了说明,为新井解释和老井复查提供了依据,在油气勘探开发过程中发挥了重要作用。

As the faults are well developed, reservoir types are complex, fluid distinguishing is relatively difficult in oil zones in Shang 12 Block of Yushulin Oilfield, all these have brought certain difficulties for oil-gas-water interpretation and caused many interpretation errors. According to this situation, a complete re-examination was carried out surrounding the area data, summarizing the features, such as the oil-bearing colors, plump degree, oil-gas smell, physical properties, systematic correlation of core, cutting and wall core, gas chromatography and fluorescence under the fluoroscope, etc. The interpretation chart for oil-gas zone in Fuyang Block was established by using rock pyrolysis parameter combined with wireline logging parameters, making the interpretation standards more perfect, altering the traditional interpretation methods, solving the distinguishing problems of questionable reservoir fluid properties and reaching the aim of fine interpretation. The authors explained the application results of the method by practical examples of wells SH 12-2 and SH 4-102-56 and provided the basis for the interpretation of new wells and re-examination of old wells. All these played an important role during oil-gas exploration and development.
