摘要： Methods and apparatus for downhole analysis of formation fluids by isolating the fluids from the formation and/or borehole in a pressure and volume control unit that is integrated with a flowline of a fluid analysis module and determining fluid characteristics of the isolated fluids. Parameters of interest may be derived for formation fluids in a static state and undesirable formation fluids may be drained and replaced with formation fluids that are suitable for downhole characterization or surface sample extraction. Isolated formation fluids may be circulated in a loop of the flowline for phase behavior characterization. Real-time analysis of the fluids may be performed at or near downhole conditions.

摘要： Methods and apparatus for investigating a hydrocarbon bearing geological formation traversed by a borehole are disclosed. A borehole tool is used to acquire a sample of fluid in the formation. Compositional analysis of the fluid sample is conducted to provide a determination of the composition of the sample. The sample composition is then related to a model of the thermodynamic behavior of the fluid; i.e., the mass fractions of the fluid components are used as inputs to an equation of state (EOS) to predict the phase behavior of the fluid.

摘要： A method for performing fluid influx tests in a wellbore (3) traversing a permeable formation (4) to test the compatibility of one or more completion fluids comprises: a) inserting a well test device (1) comprising a straddle packer assembly (6A,6B) into the wellbore (3) such that the straddle packer assembly (6A,6B) separates a well test section (13) from other sections of the wellbore; b) performing a first fluid influx test during which the fluid pressure the test section (13) is reduced, pore fluid is induced to flow from the pores of the permeable formation (4) into the test section (13) and fluid influx into the test section (13) is monitored; c) injecting a completion fluid into the test section (13), thereby increasing the fluid pressure within the test section and inducing the completion fluid to flow into the pores of the surrounding formation (4); d) performing a second fluid influx test during which the fluid pressure within the test section (13) is reduced, the completion fluid and pore fluid are induced to flow into the test section, and fluid influx into the test section is monitored; e) comparing fluid influx monitoring data acquired during the first and second fluid influx tests according to step b) and d) to determine any effects of the completion fluid on the influx of formation pore fluid into the test section.
