测井数据处理与综合解释,就是按照预定的地质任务,用计算机对测井资料进行自动处理,并综合地质、录井和开发资料进行综合分析解释,以解决地层划分、油气储集层和有用矿藏的评价及其他地质与工程技术问题。组合测井曲线的主要项目包括常规九条曲线:岩性:井径(CAL)、自然电位(SP)、自然伽马(GR);孔隙度:声波时差(AC/DT)、岩性密度(DEN/RHOB)、补偿中子(CNL/NPHI);电阻率:深侧向(RLLD)、浅侧向(RLLS)、微侧向(RMLL)或者深感应(RILD)、中感应(RILM)、八侧向(RFOC)。通过测井解释处理软件的数据图像化和其它预处理,研究人员可根据处理后的资料应用于以下几个方面:1.油气层识别;2.储量参数确定;3.地层对比;4.岩性、岩相划分、储层评价;5.构造倾向、地应力方向;6.生油岩评价;7.煤层评价;8.合成记录,最终达到测井数据的解释和解决工程与技术问题。本设计基于对组合测井曲线的数据成图和九大指标的技术原理分析,对组合测井技术进行全面研究论证,并通过数据成图技术和预分析技术对井位的地质问题进行分析得出结论,论证结论对大部分单井的组合测井数据均可使用。
Well logging data processing and comprehensive interpretation, is in accordance with the scheduled geological tasks, with the computer log data automatically processed and integrated geology, mud logging and development data for comprehensive analysis and interpretation to address the formation, oil and gas reservoirs and useful Mineral evaluation and other geological and engineering technical issues. The main items of the combined logging curve include the conventional nine curves: lithology: calorimeter (CAL), natural potential (SP), natural gamma (GR); porosity: Acoustic Time Lag (AC / DT) / RHOB), compensated neutron (CNL / NPHI); resistivity: RLLD, RLLS, RMLL, RILM, Lateral (RFOC). Through data visualization and other preprocessing of log interpretation software, researchers can apply the following data to the following aspects: 1. Reservoir identification; 2. Determination of reserve parameters; 3. Stratigraphic comparisons; 4. Rock Lithology, lithofacies classification, reservoir evaluation; 5. tectonic orientation, direction of geostress; 6. biogenic oil rock evaluation; 7. coal seam evaluation; 8. synthetic records, finally logging data interpretation and solution to engineering and technical problems. The design based on the combination of well logging data mapping and nine major technical indicators of the principle analysis of composite logging technology to conduct a comprehensive study and demonstration, and through the data mapping technology and pre-analysis of geological problems in the well In conclusion, the conclusion of the demonstration can be used for most single-well combined well logging data.
