“…As shown in Table 2 and Table 3, even more factors such as mud rheology, cuttings concentration were considered in some correlations and models, complexity of cuttings transport leads to the big gap between theoretic studies and real drilling conditions. Therefore, steady layer models [51,55], transient models [32,[56][57][58][59][60], multi-region models [61,62], correlations [25,37,38,63] constantly appeared in the recent years.…”

“…Besides layer models, the two-region system composed of a fluid bed and a stationary bed was introduced by Espinosa-Paredes et al [61], and the averaging method was used to analyze it. The averaging pressure drop and averaging velocity were solved numerically by using the finite-difference technique in the implicit scheme, and the results agree well with experimental data.…”

“…The averaging pressure drop and averaging velocity were solved numerically by using the finite-difference technique in the implicit scheme, and the results agree well with experimental data. Salazar-Mendoza [62] considered at the bottom of the horizontal pipe a region made with a stationary cuttings bed based on EspinosaParedes et al [61] model, and developed three-region system for cuttings transport. However, the two models is difficulty to be solved for cuttings bed height or cuttings concentrations.…”

Abstract:Complex structural wells are widely used in the development of marine oilfield, old oilfield and low permeable oilfield. However, poor hole cleaning is often occurred in the highly-deviated sections and horizontal sections of the complex structural wells, which affects rate of penetration and downhole safety.The methods to study cuttings transport can be normally divided into four types: 1) experimental observations, 2) CFD simulations, 3) theoretical correlations and models and 4) field tests. Experimental observations and CFD simulations are mainly used to analyze the effects of different parameters on hole cleaning and obtain some valuable data. Theoretical models and correlations are mainly applied to calculate cuttings bed height, critical velocity and etc to provide the guidance for the design of hydraulic parameters. The accuracy of the first three types are checked by field tests. In this paper, the effects of flow rate, inclination, mud rheology, drillpipe rotation and other factors on hole cleaning, and some typical correlations and models were briefly reviewed before 2000 years, and some new research findings were detailedly addressed. In addition, CFD simulations also were introduced.Although major improvements have been achieved in the past several decades, building a comprehensive and proven model requires much more experimental researches, CFD simulations, in-depth theoretic studies and field tests due to the complexity of cuttings transport under multi-factor interactions.

“…Researchers have demonstrated that particle transport is affected by many factors, such as drill pipe diameter, drill pipe rotation, drill pipe eccentricity, well inclination, and drilling fluid rheological properties (Capo, Yu, Miska, Takach, & Ahmed, 2006;Chen et al, 2007;Clark & Bickham, 1994;Espinosa-Paredes, Salazar-Mendoza, & Cazarez-Candia, 2007;Kelessidis & Bandelis, 2004;Ozbayoglu, Miska, Reed, & Takach, 2005;Ozbayoglu, Saasen, Sorgun, & Svanes, 2010;Ramadan, Skalle, Johansen, Svein, & Saasen, 2001;Sanchez, Azar, Bassal, & Martins, 1999;Tomren, Iyoho, & Azar, 1986). However, there remains a dearth of information on the effects of particle shape on the hole cleaning process in directional well drilling.…”
