Oil-based drilling fluids are essential for challenging drilling operations. However oil-based drilling fluid after using for the well site and the surrounding environment also poses a serious negative effect. Therefore, for studying on harmless technology of waste oil-based drilling fluid in this paper. Base on the tradition treatment technology for waste oil-based drilling fluid, by the preferred for treatment chemicals, improved the experimental methods and conditions, achieved some research results. Added 8.5g/L xylene/ispropanol complex demulsifier under the 50°C, pH value of 4 conditions to breaking the waste oil-based drilling fluid, the remove base oil rate is 84%, the moisture content is less than 1%, reached the "Twelfth Five-Year" major projects of national requirements' indicators; added 11ml/100g breaker SW-B, 10g/100g lime and 30g/100g cement to system for curing the waste drilling fluid, the solidified strength of the cured than 0.5MPa; Determined to leaching toxicity of solid waste, the pollution index of leaching toxicity of solid waste meeting National Integrated wastewater discharge standard (GB8978-1996).

The properties of ceramic materials can be greatly influenced when a residue is added to its composition. This article aims to study the incorporation of waste oil well drilling fluid in the standard bulk for fabrication of red ceramic. The success of the merger can reduce costs in the production of ceramic pieces and reduce the environmental impacts caused by waste. The results reveals that the use of the residue for the manufacture of the ceramic products is possible (tiles, massive bricks and hollow bricks) replacing clay up to 40%, according the requirements of the norm and in the literature for the technological properties of the final product.

Femoral neck fractures are common fractures in the elderly, especially in elderly women. There are many mature treatment methods for femoral neck fractures. However, which option is better is still controversial. In order to allow clinicians to better develop treatment plans for elderly patients with femoral neck fractures, this article summarizes the diagnosis and treatment status of elderly femoral neck fractures from the aspects of epidemiology, etiology and diagnosis, treatment methods and progress of elderly femoral neck fractures.

Environment Protection and Food Security are included in the key issues of people’s livelihood during the Twelfth Five-Year Plan. The waste oil, which direct discharge of it would pollute the environment, thus threatening the environment; what’s more, it would do great harm to the health of people, challenges food security seriously. Enhancing the supervision of waste oil is an important task of social problem. Based on the practical researches in some areas such as Beijing and Chongqing, with other studies about the same subject and comparison of the experience abroad, this article elaborates on the current status, causes and hazards of the waste oil systematically. It also has put forward a sound system of supervision. All of these are important for people to have better understanding and complete solution of the problem.

And Performance

Oil-based drilling fluid is used more and more in the field of oil and gas exploration. However, because of unrecyclable treating agent and hard treatment conditions, the traditional treating technologies of waste oil-based drilling fluid have some defects, such as waste of resource, bulky equipment, complex treatment processes, and low oil recovery rate. In this work, switchable deoiling agent (SDA), as a novel surfactant for treatment of waste oil-based drilling fluid, was synthesized by amine, formic acid, and formaldehyde solution. With this agent, the waste oil-based drilling fluid can be treated without complex process and expensive equipment. Furthermore, the agent used in the treatment can be recycled, which reduces waste of resource and energy. The switch performance, deoiling performance, structural characterization, and mechanisms of action are studied. The experimental results show that the oil content of the recycled oil is higher than 96% and more than 93% oil in waste oil-based drilling fluid can be recycled. The oil content of the solid residues of deoiling is less than 3%.

Numerical Errors

An examination of some specialized lunar and planetary ephemerides has revealed inconsistencies in the adopted planetary masses, the presence of non-gravitational terms, and some outright numerical errors. They should be considered of temporary usefulness only, subject to subsequent amendment as required for the interpretation of observational data.
