Engineering Contradiction Analysis
1Measurement precision
If traditional rheology testing methods are used to determine wellbore fluid properties, then measurement precision is improved, but time consumption increases significantly
Solution Approach 1:
The patent performs comprehensive rheology tests on test fluids at multiple temperatures and pressures beforehand to generate master curves and parameterized correlations. This preliminary characterization allows the system to predict in-situ fluid properties rapidly during wellbore construction without conducting time-consuming tests at each condition, thus resolving the contradiction between measurement precision and time consumption.
Solution Approach 2:
The patent creates simplified mathematical models (parameterized correlations) that replicate the complex rheological behavior of wellbore fluids. These models serve as copies of the actual fluid properties, enabling rapid prediction of viscosity and other rheological parameters at any temperature and pressure condition without requiring physical testing, thereby maintaining accuracy while dramatically reducing time requirements.
2Reliability
If comprehensive rheology tests are conducted at multiple temperatures and pressures, then reliability of fluid property data is improved, but device complexity and operational complexity increase
Solution Approach 1:
The patent develops a universal testing approach where a single rheology test setup can characterize fluids across a wide range of temperatures and pressures by using temperature-controlled environments and pressure-adjustable configurations. The generated master curves and parameterized correlations serve as universal tools that can predict fluid behavior at any condition within the characterized range, eliminating the need for multiple specialized test devices and simplifying operational complexity while maintaining data reliability.
3Ease of operation
If real-time monitoring of wellbore fluid properties is implemented, then operational control is improved, but measurement and calculation complexity increases
Solution Approach 1:
The patent replaces complex physical measurement systems with mathematical modeling and data analytics. By using parameterized correlations and master curves, the system calculates in-situ fluid properties from readily available operational data (temperature, pressure, flow rate) rather than requiring complex real-time rheological measurements. This substitution simplifies the measurement system while enabling real-time monitoring and operational control through straightforward calculations.

AI summary
Examples of techniques for performing a wellbore construction operation in a wellbore are disclosed. In one example implementation according to aspects of the present disclosure, a computer-implemented method includes: performing a rheology test on a test fluid, the test fluid being representative of a fluid pumped through the wellbore, to generate test fluid data; performing, by the processing device, a data analysis on the test fluid data to generate at least one parameterized correlation; measuring a first property of the fluid to generate measured data; calculating, by the processing device, a second property of the fluid in the wellbore by using the parameterized correlations and the measured data to generate calculated data; and changing a parameter of the wellbore construction operation based at least in part on the calculated data.
