The Research of the Oil Base Drilling Fluid Hard Brittle Shale Sidewall Instability Mechanism Zhen Guangfeng1 ,Jing Golin1, Hu weijie2, Liaobaisun2 1 Provincial Key Laboratory of Oil ＆Gas Chemical Technology, College of Chemistry ＆ Chemical Engineering, Northeast Petroleum University,Daqing,163318,China 2 Oil Recovery Plant No. 5, Daqing 163514, China Keywords: Wellbore instability; The Formation of the Shale; Drilling fluid; Cation exchange capacity; Hydration reaction Abstract.
Pore and micro cracks reduce oil processing samples, rational layer sample variation and water treatment compared with the sample, under the electron microscope is more bright, this is due to less conductive material in water samples, the hydration clay mineral equivalent more, so to prove that water treatment more easily than oil processing sample hydration.

Application of computer network technology to control the coal quality Yuan Chen 1, a , Lanfen Niu 2, a,, Guobiao Ren 3, a 1School of Information Engineering, Zhengzhou University, China 2School of Mathematics and Statistics, Zhengzhou University, China 3School of Mathematics and Statistics, Zhengzhou University, China a zzdxChenYuan@126.com Keywords: coal quality; computer network; informatization; quality control Abstract: In recent years, the government has stepped up efforts to control coal mine.
As coal is a substantial breach of non-renewable resources, the competitions in the coal market are increasingly fierce; coal quality has become a major factor in the coal sales business, more and more enterprises regard the coal quality as a key of improving their competitiveness.
This requires the enterprise controls the quality of coal in every link, from the production, processing, transportation to marketing, which undoubtedly requires a lot of manpower and material resources.
