摘要： Methods and systems for testing a subterranean formation penetrated by a wellbore are provided. A testing tool has a plurality of packers spaced apart along the axis of the tool, and at least a testing port. The testing tool is positioned into the wellbore and packers are extended into sealing engagement with the wellbore wall, sealing thereby an interval of the wellbore. In some embodiments, the wellbore interval sealed between two packers is adjusted downhole. In one embodiment, the location of the testing port is adjusted between two packers. The methods may be used to advantage for reducing the contamination of the formation fluid by fluids or debris in the wellbore.

摘要： A downhole connate water sample drawn from the formation surrounding a well is validated when mud filtrate concentration is acceptably low. A preferred method includes drilling the well with a water-based drilling fluid, or more generally a water-based mud (WBM), containing a water-soluble dye. The dye acts as a tracer to distinguish connate water from WBM filtrate in a downhole sample of formation fluid contaminated by mud filtrate from the water-based mud. Preferably, an optical analyzer in a sampling tool measures light transmitted through the downhole sample to produce optical density data indicative of dye concentration. Preferably, optical density is measured at a first wavelength to obtain a first optical density, and at a second wavelength, close in wavelength to the first wavelength, to obtain a second optical density. First and second optical density data are transmitted to the surface. At the surface, in a data processor, the second optical density is subtracted from the first optical density to produce a third optical density that is substantially free of scattering error. The data processor validates each sample that has an acceptably low third optical density. The invention also provides a method of determining when to collect a sample of downhole fluid drawn over a period of time from a formation surrounding a well.
摘要翻译：当泥浆滤液浓度可接受地低时，从井周围的地层抽取的井下合生水样品被验证。优选的方法包括用含水溶性染料的水基钻井液或更一般的水基泥浆（WBM）钻井。该染料作为示踪剂，以在由水基泥浆泥浆滤液污染的地层流体的井下样品中区分原生水与WBM滤液。优选地，采样工具中的光学分析仪测量透过井下样品的光，以产生指示染料浓度的光密度数据。优选地，在第一波长处测量光密度以获得第一光密度，并且在第二波长处以与第一波长相近的波长，以获得第二光密度。第一和第二光密度数据被传送到表面。在表面上，在数据处理器中，从第一光密度中减去第二光密度以产生基本上没有散射误差的第三光密度。数据处理器验证每个具有可接受的低第三光密度的样品。本发明还提供了一种确定何时收集从围绕井的地层在一段时间内被抽取的井下流体样本的方法。
