The composition of oilfield water is complex and diverse. development application corrosion inhibitors can effectively inhibit the pipelines equipment by water. ions in produced Jidong Oilfield were determined instrumental analysis chemical analysis. Triazine prepared from ethanolamine formaldehyde as inhibitor was evaluated weight loss method. inhibition experiments carried out ancient samples...

The conventional measurement method can no longer guarantee the accuracy requirement after the oilfield development entering high water cut stage, due to the water content and gas phase in the flow. In order to overcome the impact of measurement deviation the oilfield productionmanagement, the flow field of three-phase separator is studied numerically in this paper using Fluent 6.3.26. Taking i...

Time variability of reservoir parameters in water flooding has an effect on oilfield development rules. Meanwhile, time variability of different reservoir macro-parameters has certain synergetic relationship with each other. Based on microscopic network simulation and reservoir numerical simulation, a new simulation method is presented, which can describe the influence of reservoir parameters' ...

Wellbore instability is one of the major problems that hamper the drilling speed in Halfaya Oilfield. Comprehensive analysis of geological and engineering data indicates that Halfaya Oilfield features fractured shale in the Nahr Umr Formation. Complex accidents such as wellbore collapse and sticking emerged frequently in this formation. Tests and theoretical analysis revealed that wellbore inst...

Water-soluble hydrophobically associating polymers are examined with particular emphasis on their rheology for oilfield applications. The incorporation of a small amount (less than 1 mol%) of hydrophobic groups into the polymer backbone of a water-soluble polymer dramatically alters the rheological properties of the resulting material. Associating polymers have potential for use in mobility con...

Herein, we introduce a low-cost, available, renewable, and effective solid adsorbent used for oilfield-produced-water treatment using straightforward process. In the present study, sheep dung ash was prepared same way this waste is produced in rural areas when as source of energy cooking heating: by burning with direct flame. The characterized FTIR, EDX, SEM analysis techniques. feasibility red...
