Evaluation Indexes of Environmental Protection and a Novel System for Offshore Drilling Fluid

Petroleum Science and Technology (2013)

Shuixiang Xie Guancheng Jiang Mingqiang Chen Z. Y. Li Hongzhi Mao

Oil resources are abundant in the offshore area that is an important channel for the human to obtain oil and gas. With oil exploration and development, the marine ecological environment has been influenced increasingly. Through a large number of laboratory tests, the evaluation indexes of the environmental offshore drilling fluid system were established, which are consisted of heavy metal, petroleum, acute biological toxicity, biodegradability, and so on. Four types of agents for environmental offshore drilling fluid and a novel environmental offshore drilling fluid system were developed on the basis of establishing the evaluation indexes. The basic formulation of the novel drilling fluid system is: 400 mL Seawater + 0.3% Na2CO3 + 0.2% NaOH + 4% Bentonite +0.5% HXB-1 + 2% MMF + 1.5% SDR-30 + 1%HXJ + 1% SDE-1 + 2%NFA-25, and the system has been applied successfully to Bohai Bay in Shengli oil field. The results showed that the environmental offshore drilling fluid system had favorable drilling performances, met the requirements of drilling engineering and marine environmental protection, and realized the source control of the environmental contamination from offshore drilling, the environmental performances of which were superior to sulfonated polymer drilling fluid and oil-based drilling fluid.

The Enhanced Photocatalytic Properties for Water Oxidation over Bi/BiVO₄/V₂O₅ Composite

The Journal of Physical Chemistry C (2017)

Xiaofeng Xu Shufang Kou Xia Guo Xiaotong Li Xiaojian Ma

Bi/BiVO4/V2O5 has been successfully synthesized by a simple annealing of BiVO4 in Ar/H2. The obtained Bi/BiVO4/V2O5 was characterized by X-ray diffraction (XRD), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), and transmission electron microscopy (TEM). The photocatalytic activities are examined by an oxygen-evolution reaction. When BiO/BiVO4/V2O5 in air and Bi2VO5.5/ BiVO4/V2O5 in vacuum were compared with the products annealing in other atmospheres, Bi/BiVO4/V2O5 exhibited the best performance (2413 μmol·g–1·h–1), which could be attributed to the synergistic combination of Bi, BiVO4, and V2O5. This study may open up a new avenue for the development of an efficient composite photocatalyst.
