Application of a novel associative polymer on synthetic-based drilling muds for deepwater drilling


This paper aims at evaluating the flat-rheology performance of a novel associative polymer (AP) on synthetic-based drilling muds (SBM) for deepwater drilling and exploring the mode of action. The associative polymer was synthesized by dimer acid, triethylenetetramine and polyoxyethylene lauramine on the basis of chemical modification in aqueous, and the adjusting rheology performance of AP was evaluated through mud making tests at two densities and oil/ water ratios (OWR). The results show that AP performs extremely well on adjust the rheology of SBM within a broad temperature range from 4°C to 65°C, especially for the key rheological parameters of deep-water drilling, such as yield point, gel strengths and 6-rpm reading. Based on a combined use of FT-IR, XRD, particle-size distribution, polarizing microscope, rheology test of emulsions and TEM analysis, the probable flat rheology mechanism was determined due to the specific adsorption structure at interphase. The results indicate that the enhancement of slippage between the dispersed droplets and the layer of organic clay is primarily responsible for the excellent adjusting rheology ability of AP.

Keywords: flat-rheology, associative polymer, synthetic-based muds, deep-water drilling, adsorption structure.

Research on the corrosion mechanism of CO2/H2S mixture to cement stone


CO2 and H2S have different corrosion effects on cement stone under wet conditions. Little research has been performed to date on the corrosive effect of CO2/H2S mixture to cement. However, the mixture usually exists in many sour gas reservoirs. Cement stone samples corroded by H2S/CO2 mixture under different temperature and pressure are tested to probe the change of compressive strength and permeability. Microstructure and corroded products of corroded samples were observed by SEM and XRD. The result shows the corrosion products of CO2/H2S mixture to cement are similar to those by single-component H2S or CO2 gas, except that the formation of expansive crystal is inhibited. Corroded products caused by CO2 mainly locate at the outer layers of cement, while the corroded products caused by H2S mainly exist at the inside the cement. CO2 dominates the whole corrosion process after a long duration.

Keywords: corrosion mechanism, carbon dioxide, hydrogen sulfide, cement stone, well cementing

A generalized hydraulic calculation model for non-newtonian fluid pipe flow and its application evaluation


A generalized hydraulic model that is independent of the rheological model is presented for non-Newtonian fluids flow in pipes. The generalized model was developed without assuming that the generalized flow index (n’) remains constant over all shear rates. Based on the pipe flow control equation, the explicit equations between the wall shear stress and volumetric flow of all common rheological models flowing in pipe were obtained, such as the Casson model, Herschel-Bulkley model and the Robertson-Stiff model, and they all can be solved numerically to obtain the accurate wall shear rate and shear stress. We give the theoretic calculation method of n’ for all time-independent non-Newtonian fluids. This method is applicable to all common rheological models without the assumption that n’ is constant. Moreover, we derived the general expression of generalized Reynolds number and then gave a utility pressure loss calculation model. A set of measured hydraulic data were utilized to evaluate this model. The results show that it can precisely calculate pipe flow parameters for all types of different non-Newtonian fluid. The proposed model will lay a foundation for the application and more extensive use of complex but more precise rheological models in engineering.

Keywords: pipe flow, hydraulic calculation, generalized Reynolds number, evaluation analysis.

Efficiency assessment of water-alternating-gas for «Кalamkas» field Ю-1С horizon test plot in accordance with penetration test results in core


In recent years, in world practice, for production stimulation of hard-to-recover oil reserves, the relatively new technology of production enhancement using water-alternating-gas (WAG) has found increasingly greater application. In the article, results of experimental research on efficiency assessment of WAG methods relating to oil of the «Kalamkas» field Ю-1С horizon of Kazakhstan Republic are considered. Research results showed the efficiency of displacement of oil remaining after water flooding by the WAG method, including through usage of surfaceactive agents (SAA).

Influence of external factors on bioinfestation process of «Jetibay» oil field


Dependence of «Jetibay» oil field bioinfestation from external factors were analyzed. The main source of bioinfestation is a long injection process of unsterilized surface water. There is a significant temperature dependence on the activity of SRB (Sulphate Reducing Bacteria) and the amount of hydrogen sulfide generated. In addition, a gradual increase in well watering and modification of associated water cation-anionic composition also increases the corrosive condition in the fields.

Loss of oil and oil refinery products in transportation storage objects and their normalization


The issues of loss and normalization of oil and oil refinery products in transportation and storage objects were investigated in the article. Loss of oil and oil products is mainly the result of leakage in reservoirs and pipelines, evaporation, incomplete discharge of transporting tankers, mixture and flooding of products, accidents on the cleansing period of containers. These losses not only inflict damages on the country’s economy also decrease production effectiveness and cause contamination of soil, air and water basins. Normalization of losses during the transportation and storage of oil and oil products makes it possible to decrease the amount of losses which occur in technical and technological operations on each source of loss.
