This paper analyzed the glutenite reservoir pore structure characteristics and percolation mechanism, according to the normalized permeability curves, combining the NMR. The 100% water production rate’s displacement volume was taken as a benchmark and with the concept of water flooding control degree a more concise empirical formula was given where the water production rate changed with the recovery degree and water flooding volume coefficient. The examples of two blocks of Karamay oilfield agreed well with the production practice, clearly defined the direction of subsequent water flooding development work. © (2014) Trans Tech Publications, Switzerland.

Using the time-frequency analysis method which is applicable to the seismic sequence analysis, this paper calculates seismic and well log time-frequency spectra, respectively. Based on the characteristics of the sedimentary cycle and remarkable-reflection interface time-sequency spectra, it studies the horizon corresponding relationship using the time-sequency spectra of the log data and seismic data. On the basis of the synthetic seismogram calibration, it also analyzes the correlation of the sequency spectra from the synthetic seismogram and the trace near the wed. Then, the existing time-depth relationship is corrected through the traveling time of the same horizon in the corresponding well and seismic in order to improve the accuracy of time-depth conversion. Because there exists drift in the logging and the seismic horizon is fixed in well-seismic calibration, the well log in the logging horizon is stretched, compressed and translated relative to that in the seismic horizon. According to the image mapping principle, the well log horizon is adjusted. Finally, based on a reference time-depth relation, the good effects are obtained by using this method to analyze the timesequency spectrum and correct the time-depth relationship of multiple curves of the real well and seismic data from different areas.

Due to the excellent performance of steel, construction steel structure is widely used. The disaster records of American Northridge Earthquake and Great Hanshin Earthquake indicated that the destruction of the rigid steel frame mainly manifested as brittle fracture of beam-column joints, while little metal plastic deformation occurred on the beam. Therefore, with modified nodal method to realize the design goal, "Strong Column and Weak Beam, Strong-Joint and Weak-member", will be of great importance to ensure the seismic safety of resistance to earthquake of the steel structure. Taking stud welded connection nodes of steel structure beam-column as the research object, this paper analyzed and compared the bearing capacity of beam column basic nodes and dog-bone optimized nodes with ANSYS finite element analysis software. According to three weaken parameters of dog-bone connections, designing three groups of models with nine different sizes, making calculation under cyclic loading and monotonic loading, through contrastive analysis to hysteretic curve, equivalent stress cloud picture and three stress section route display images, we propose the suggestion of determining the value of weaken parameters of dog-bone connectio. © 2014 ejge.

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.

The constitutive equation of the material is an essential ingredient of any structural calculation. In this article, a phenomenological constitutive model is established to describe the dynamic deformation behavior of 30Cr2Ni4MoV steel in wide strain rate, strain, and temperature ranges. Also, the mathematical models to predict peak stress and corresponding strain were obtained. The stress-strain values predicted by the developed model well agree with experimental results, which confirmed that the developed constitutive equation gives an accurate and precise estimate for the flow stress of 30Cr2Ni4MoV steel. © 2011 Springer Science+Business Media, LLC.

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.

Porous carbon was prepared from furfuryl alcohol by template method with doubleimpregnation and was characterized by means of XRD, SEM, FTIR and N2 adsorption-desorption. The adsorption equilibrium isotherms of CH4, N2 and CO2 on the porous carbon were measured by means of magnetic suspension balance. The Langmuir model was used to fit the adsorption isotherm data and the equilibrium selectivities of the mixed gas were predicted by the Henry constants. The characterization results showed that the pore size distribution of the porous carbon was narrow and it kept the regular structure of zeolite to some extent with surface polarity, which was beneficial to the adsorption and separation of CH4, N2, CO2. The order of their equilibrium adsorption capacity on the porous carbon is CO2>CH4>N2. All the correlation coefficients for the Langmuir model are greater than 0.993. The porous carbon is suitable for the adsorption and separation of CO2 in flue gases and the purification of unconventional gas namely coalbed methane, but its separation effect for landfill gas is not significant. © 2016, SINOPEC Beijing Research Institute of Chemical Industry.
