This paper was focused on the permeability reduction performance of a hyperbranched polymer in high permeability porous medium. Water solubility, rheological property, viscoelasticity, and filtration experiments were adopted for investigating the solubility and injectivity of the hyperbranched polymer. Atomic force microscope (AFM), scanning electron microscope (SEM), and shear experiments were conducted for studying the microscopic structure, adsorption behavior, and shear resistance, respectively. Besides, resistance factor (RF), residual resistance factor (RRF), and displacement experiments were adopted for investigating the permeability reduction performance and enhanced oil recovery (EOR) ability of the hyperbranched polymer. It was found that the hyperbranched polymer exhibited acceptable water solubility, remarkable shear resistance, perfect permeability reduction and EOR ability. It was also found that the hyperbranched polymer owned higher apparent viscosity, viscosity retention rate, and adsorption retention due to the special network structure of polymer molecular chain. © 2013 Elsevier B.V.

For fatigue monitoring issues, this paper proposes the idea that detects the heart rate volatility to determine whether the driver is in a state of fatigue, and the method is to comprehensively analyze the standard deviation which obtains by the feedbackmonitoring historical data of heart rate fluctuation, then determine whether the driver in the day Time is excited in the paragraphs or tired in the paragraphs. Finally, the development of vehicle monitoring system of dangerous goods transport based on GPS/3G/ArcGIS apply research results, and access to the optimal solution of the driver scheduling. An application shows that detecting the heart rate variability to determine if the driver is tired is of practical significance, and it is well used in the design of monitoring system for dangerous goods transport vehicles. © 2014 IEEE.

Chepaizi of the Junggar basin, Cretaceous Qingshui River formation (K1q) and Jurassic eight bay group (Jib) in Wsu area have rich oil and gas resources, drill stem test is done in the area of Shamenl well. Shiqiaol well and Shamen4 well to realize breakthrough of exploration. But because of the complex formation situation, stuck drill stem for differential pressure has been happened several times in the course of open hole test, and even complicated situation of fractured testing string is appeared, resulting sidetracking. Based on study of the strata in this area and full preparation of the well bore, mud and drill-stem testing process, stuck drill stem for differential pressure has been solved. Source

The DX1805 well and the DX1813 well are two development wells at the Dixi 18 well area of the Junggar basin. By using underbal-anced drilling technology, it is not only to improve the speed of drilling, protect the reservoir, but also to shorten the oil test cycle. The DX1805 Wells gains industrial capacity unreconstructed, and by applied the sand fracturing transformation technology to the DX2013 well, the reservoir flow capacity is improved better, and reservoir capacity greatly increased. These two wells are utilized of isochronal well testing, both of them have industrial capacity. Source
