摘要： A method and apparatus store energy in an energy storage medium located in an energy storage chamber. As a sampling tool descends into the borehole, the energy storage medium is pressurized with hydrostatic pressure. A sample is collected in a sample chamber by pumping formation fluid into the sample chamber against hydrostatic pressure. The energy storage medium applies the energy stored in the energy storage medium to the sample through a pressure communication member. A pressure multiplier member increases the pressure applied on the sample by the energy storage medium through the pressure communication member to keep pressure on the sample. A biasing water pressure is applied to the sample at the surface so that the energy storage chamber can be removed from the sample chamber.

摘要： The present invention provides a sample tank having a window for introduction of electromagnetic energy into the sample tank for analyzing a formation fluid sample down hole or at the surface without disturbing the sample. Near infrared, mid infrared and visible light analysis is performed on the sample to provide a downhole in situ or surface on site analysis of sample properties and contamination level. The onsite analysis comprises determination of gas oil ratio, API gravity and various other parameters which can be estimated by a trained neural network or chemometric equation. A flexural mechanical resonator is also provided to measure fluid density and viscosity from which additional parameters can be estimated by a trained neural network or chemometric equation. The sample tank is pressurized to obviate adverse pressure drop or other effects of diverting a small sample.

摘要： One embodiment of the invention comprises a tool string (10) for testing a wellbore formation that includes a production inlet (20), an injection outlet (22), and a sampler apparatus (54). Fluid is taken from a production zone (16), into the tool string (10) through the production inlet (20), out of the tool string through the injection outlet (22), and into the injection zone (18). Within the interior of the tool string, the sampler apparatus takes samples of the fluid flowing therethrough. In another embodiment, a large volume of sample fluid is trapped within the interior of the tool string, such as between two valves (52, 26), and is removed from the wellbore along with the tool string subsequent to the test. In another embodiment, the tool string includes at least one perforating gun (96) to perforate one of the production and injection zones. The tool string may also include two perforating guns to perforate both the production and injection zones. One of the two perforating guns may be an oriented perforating gun so that upon activation the shapedcharges do not disturb any of the cables, data lines (104), or transmission lines associated with the tool string.

摘要： A well fluid sampling tool and method for retrieving chemically accurate hydrocarbon samples from new wells. The sampling tool is provided with a chemically inert sample chamber and lowered to the required depth in the well where a well fluid sample is admitted to the sample chamber, which is subsequently sealed. The tool is preferably arranged so that pressures inside and outside the sample chamber remain substantially equal during and after sample taking. The sample may be subject to post-sampling pressurisation to keep the sample in its original single-phase state. The chemical inertness of the sample chamber avoids removal of reactive components of the well fluid from the sample by chemical reaction with the material of the sample chamber (which is conventionally metal). This enables accurate assessment of new wells without the need for extended flow testing. Equalisation of pressures inside and outside the sample chamber enables the material of the sample chamber to be selected for its chemical inertness rather than for mechanical strength to resist forces otherwise arising from pressure imbalances.
摘要翻译：一种良好的流体采样工具和从新井采集化学准确的烃样品的方法。采样工具具有化学惰性的样品室，并降低到井中所需的深度，其中井流体样品进入样品室，随后密封。该工具优选地布置成使得样品室内和外部的压力在取样期间和之后保持基本相等。样品可以进行采样后加压，以使样品保持原始的单相状态。样品室的化学惰性避免了通过与样品室（通常为金属）的材料的化学反应从样品中去除井流体的反应性组分。这使得能够准确地评估新的井，而不需要扩展的流量测试。样品室内部和外部的压力均衡使样品室的材料能够以其化学惰性而不是机械强度来选择，以抵抗由压力不平衡引起的力。
