Anode Substrate

The voltage is the critical electrochemical parameter in microbial fuel cells (MFCs).There are three major oilfield wastewaters including water flooding produced water, polymer flooding produced water and ASP flooding produced water. These three wastewaters were used as anode substrate of three MFCs in this study. The influence and the influencing factors of the output voltage of the three MFCs and the produced water main refractory organics removal effect were studied. The results show that During this reaction period, MFCs cathode potential stays relative stable, however, anode potential shows a remarkable increasing trend, thus, the anode contributes mostly to the change in output voltage. COD removal effect of Anode substrate and the coulombic efficiency are both influencing factors of the anode potential .The microbial fuel cell for wastewater of surfactant, remove the best effect;For different produced water, oil and polymer removal effect abide by the MFC output voltage and COD value changing law.

Oilfield Water

At present, most oilfields in our country has entered the mid-late development, water-flooding technology is widely accepted, multi-layer hybrid mining and multi-layer hybrid conveying process. If no compatibility between injected water and formation water or different horizon produced water is poor, it can form various types of oil field scale.Scale reservoir caused by congestion, not only can bring damage to reservoir, also can give bring different degree of corrosion of equipment and pipeline, reduce the heat transfer rate of equipment and pipeline. The scale formation, fouling hazards, scaling trend prediction and antiscale technology in oilfield produced water are introduced. It as the basis of the theory of compatibility experiments has a certain realistic guiding significance in mixed mining, mixed transportation and reinjection process.

Abstract As is known, fractured reservoirs compared to conventional reservoirs have such features as complex pore volume structure, high heterogeneity of the porosity and permeability properties etc. Apart from this, the productivity of a specific well is defined above all by the number of natural fractures penetrated by the wellbore and their properties. Development of fractured reservoirs is associated with a number of issues, one of which is related to uneven and accelerated water flooding due to water breakthrough through fractures to the wellbores, for this reason it becomes difficult to forecast the well performance. Under conditions of lack of information on the reservoir structure and aquifer activity, the 3D digital models of the field generated using the hydrodynamic simulators may feature insufficient predictive capability. However, forecasting of breakthroughs is important in terms of generating reliable HC and water production profiles and decision-making on reservoir management and field facilities for produced water treatment. Identification of possible sources of water flooding and planning of individual parameters of production well operation for the purpose of extending the water-free operation period play significant role in the development of these reservoirs. The purpose of this study is to describe the results of the hydrochemical monitoring to forecast the water flooding of the wells that penetrated a fractured reservoir on the example of a gas condensate field in Bolivia. The study contains data on the field development status and associated difficulties and uncertainties. The initial data were results of monthly analyses of the produced water and the water-gas ratio dynamics that were analyzed and compared to the data on the analogue fields. The data analysis demonstrated that first signs of water flooding for the wells of the field under study may be diagnosed through the monitoring of the produced water mineralization - the water-gas ratio (WGR) increase is preceded by the mineralization increase that may be observed approximately a month earlier. However, the data on the analogue fields shows that this period may be longer – from few months to two years. Thus, the hydrochemical method within integrated monitoring of development of a field with a fractured reservoir could be one of the efficient methods to timely adjust the well operation parameters and may extend the water-free period of its operation.
