With
the exploration and development of deep formation, deep water and
unconventional oil resources, petroleum engineering is facing more complex problems.
For example, fluid structure interaction, fluid rock interaction, drill string
dynamics and its coupling with fluid / rock, fluid dynamics and its coupling
with chemistry, drilling fluid chemistry and its coupling with formation, and
so on. On the other hand, with the development of emerging disciplines such as
big data and artificial intelligence, new solutions are provided for the above
complex problems. How to use theoretical analysis, numerical simulation,
experimental research and other means, and actively absorb new theories and
methods to study the above complex problems in petroleum engineering is the
theme of this special issue.
The purpose of this special issue is to improve the understanding of the basic laws and provide support for the safe and efficient exploration and development of complex oil and gas resources by studying the interdisciplinary problems faced by complex petroleum engineering, such as fluid mechanics, solid mechanics, drill string dynamics, rock mechanics, seepage mechanics, oilfield chemistry, safety engineering and so on.
The scope of this special issue focuses on but is not limited to the following directions:
1. Fluid dynamics and its coupling process with rock
2. String dynamics and its coupling process with fluid / rock
3. Fluid dynamics and its coupling process with chemistry
4. Oilfield chemistry and its coupling analysis with rock
5. Drilling fluid chemistry and its coupling process with formation
6. Downhole intelligent measurement and control technology

- Abstract An uncertainty analysis method is proposed for the assessment of the residual strength of a casing subjected to wear and non-uniform load in a deep well. The influence of casing residual stress, out-of-roundness and non-uniform load is considered. The distribution of multi-source parameters related to the residual anti extrusion strength and residual anti internal pressure strength of the casing after wear are determined using the probability theory. Considering the technical casing of X101 well in Xinjiang Oilfield as an example, it is shown that the randomness of casing wear depth, formation elastic modulus and formation Poisson’s ratio are the main… More

- Abstract A three-dimensional model for the numerical simulation of casing-cement behavior is used to investigate residual strength in the perforated casing of ultra deep wells. The influence of the hole diameter, hole density and phase angle on the residual strength of the casing under non-uniform stress and fracturing conditions is revealed through the consideration of different perforation parameters. It is shown that the residual strength of the casing increases with the hole diameter and periodically changes with the hole density; the phase angle is the main factor that affects the residual strength of the perforated casing, and the perforation should be… More

- Managed Pressure Drilling Technology: A Research on the Formation Adaptability
- FDMP-Fluid Dynamics & Materials Processing, Vol.18, No.6, pp. 1865-1875, 2022, DOI: 10.32604/fdmp.2022.021668

- Abstract Existing pressure drilling technologies are based on different principles and display distinct characteristics in terms of control pressure and degree of formation adaptability. In the present study, the constant-bottom-hole-pressure (CBHP) and controlled-mud-level (CML) dual gradient drilling methods are considered. Models for the equivalent circulating density (ECD) are introduced for both drilling methods, taking into account the control pressure parameters (wellhead back pressure, displacement, mud level, etc.) and the relationship between the equivalent circulating density curve in the wellbore and two different types of pressure profiles in deep-water areas. The findings suggest that the main pressure control parameter for CBHP drilling… More

- An Improved Model to Characterize Drill-String Vibrations in Rotary Drilling Applications
- FDMP-Fluid Dynamics & Materials Processing, Vol.18, No.5, pp. 1263-1273, 2022, DOI:10.32604/fdmp.2022.020405

- Abstract A specific model is elaborated for stick-slip and bit-bounce vibrations, which are dangerous dynamic phenomena typically encountered in the context of rotary drilling applications. Such a model takes into account two coupled degrees of freedom of drill-string vibrations. Moreover, it assumes a state-dependent time delay and a viscous damping for both the axial and torsional vibrations and relies on a sawtooth function to account for the cutting force fluctuation. In the frame of this theoretical approach, the influence of rock brittleness on the stability of the drill string is calculated via direct integration of the model equations. The results show… More

- Assessment of the Performances of Carboxylic Acid Monomers as Fluid Loss Additives for Oil-Well Cement

- Abstract The application of polycarboxylic acid as a fluid loss additive for cement (i.e., a substance specifically designed to lower the volume of filtrate that passes through the cement) can prolong the thickening time of cement slurries. Given the lack of data about the effects of carboxylic acid monomers as possible components for the additives traditionally used for oil-well cement, in this study different cases are experimentally investigated considering different types of these substances, concentrations, temperatures, and magnesium ion contamination. The results demonstrate that itaconic acid has a strong retarding side effect, while maleic and acrylic acids have similar influences on… More
