半渗透膜分离气体方法与稳定的气相色谱仪组合可用来分析从甲烷到辛烷的烷烃化合物、芳香烃化合物(例如苯、甲苯)、氮和二氧化碳等。整个系统可以获取钻井流体中每种气体的相对浓度。气体浓度跟踪仪研发部门从2006年9月到2007年9月研究了35口井,这些井中同时使用气体浓度跟踪(GC-Tracer)技术与可比较的分析技术如随钻测井(LWD)、电缆测井、压力-体积-温度(PVT)测试、模块式地层动态测试器(MDT)和微电阻率成像(FMI)技术,这些新技术可用于气体解释方法。GC-Tracer解释分析技术能更精确地描述储层,并区分可能的流体层段。此外,应用精确的半渗透膜技术可以推断出有关生物降解、水驱和流体成熟度方面的问题。所提供的整套数据结果表明了它不仅能应用在低阻、低渗砂岩或复杂井中的薄层,而且也可在评价井或开发井中应用,同时也表明它能带来相对可观的利益,即降低成本的同时最大化地获取油藏数据。
The semi-permeable membrane separation gas method in combination with a stable gas chromatograph can be used to analyze paraffinic compounds, methane, benzene, toluene, nitrogen and carbon dioxide from methane to octane. The entire system can obtain the relative concentration of each gas in the drilling fluid. Gas concentration tracker R & D department from September 2006 to September 2007 studied 35 wells in these wells using gas concentration tracking (GC-Tracer) technology and comparable analytical techniques such as logging-while-drilling (LWD) Cable logging, pressure-volume-temperature (PVT) testing, Modular Formation Dynamic Tester (MDT) and Micro Resistivity Imaging (FMI) technologies are available for gas interpretation methods. The GC-Tracer interpretation technique provides a more accurate description of the reservoir and distinguishes possible fluid intervals. In addition, accurate semi-permeable membrane technology can be used to infer problems with biodegradation, water flooding and fluid maturation. The complete set of data provided shows that it can be applied not only to thin layers in low-resistivity, low-permeability sandstone or complex wells, but also to appraised wells or development wells, and at the same time shows a considerable benefit Maximize reservoir data while reducing costs.
