AbstractTraditional water-in-oil drilling fluids are limited by their shear thinning behavior. In this article, we propose the synthesis of a thermal resistant quaternary ammonium salt gemini surfactant DQGE-I. This surfactant was synthesized using monomers such as N,N-dimethyl-1,3-propanediamine, organic acids and epichlorohydrin, as well as blocking groups such as N-vinylpyrrolidone (NVP). The prepared surfactant exhibited various advantages over traditional surfactants, including excellent thermal stability, good emulsifying and wetting capability. The use of these surfactants was shown to improve the compactness of emulsifier molecules at the oil/water interface, as well as the overall emulsificaiton effect. Laboratory studies revealed that water-in-oil emulsions prepared using DQGE-I showed high emulsion breaking voltage, low liquid precipitation and small and uniformly distributed emulsion drops. Highly thixotropic water-in-oil drilling fluids based on DQGE-I showed low viscosity, high shear rate and thermal tolerance up to 260oC. Additionally, the proposed fluid was applied in 16 wells (including WS1-H2, GS3 and XS1-H8) in the Daqing Oilfield. Testing showed that DQGE-1 exhibited excellent rheological behavior and wall-building capability. The emulsion breaking voltage exceeded 1500 V, and the yield point/ plastic viscosity ratio exceeded 0.4. The use of this surfactant can help to solve problems such as high formation temperature and poor well wall stability.

Viscometer is analysis instrument which is available in measuring viscosity of liquid material. The viscometer is widely used in food, inks, paints, solvents, petroleum products and various fields of industrial production. In the field of oil drilling, viscometer is mainly used for evaluation rheological parameter of drilling fluid that is beneficial to safety, fast and scientific drilling. Circular magnetic grid could improve precision and stability when it is applied in torque measurement of automatic viscometer, and its non-contact measurement and high antipollution characteristics meet the design requirements of viscometer. The improved automatic viscometer has strong stability, good consistency and automatic reading function. According to needs of users, it would automatically draw various rheological curves.

The effect of lignite on the filtration characteristics of water base mud was studied at low and high temperature. Recently, the nanoparticle additives are studied and investigated as alternative additives due to its stability during drilling even at high-temperature and high-pressure (HTHP) conditions. In this study the effect of nano particles size of Lignite on filtrate volume and mud cake thickness was investigated , at different weights (0.01, 0.05, 0.07, 0.1, and 0.2) gm, in (API WBM, Polymer mud, DURA THERM mud, and Saturated Salt Water mud) and different temperatures (35, 75, and 100) oC. The results show that most tests provided a very good filtration control for the used drilling fluids at 100 oC. Better performances were observed in polymer and Saturated Salt Water mud at 100 oC with Lignite concentration of 0.01 gm and 0.1 gm, and filtrate volume reduction 52.5 % and 60 % respectively.
