Wear resistances of co. co.rosion product films formed on P110 carbon steel at different co. partial pressures were investigated in water sand two-phase flow by weight loss method, and the microstructures and co.positions of co.rosion product films were analyzed by scanning electron microsco.e(SEM) and X-ray diffraction(XRD), respectively. The results showed that the wear rate of co. co.rosion product films increased until a maximum and then decreased with the increasing of the film-forming pressure, and the maximum occurred at 2 MPa. However, the maximal co.rosion rate and the loose and porous co. co.rosion product films were obtained at 4 MPa. And the wear rate decreased and then went to be flat with increasing test time. Furthermore, the microstructures and co.positions of co.rosion product films and the impact and wear of sand particles played an important role on wear resistances. In addition, the wear rate and co.rosion rate were fitted by cubic polynomial, respectively, which were well in acco.dance with the measured results.

The polyaniline/partially phosphorylated poly（vinyl alco.ol）（PANI/P-PVA） nanoparticles were prepared by the chemical oxidative dispersion polymerization of aniline monomer in 0.5 mol/L HC1 aqueous media with the partially phosphorylated poly（vinyl alco.ol）（P-PVA） as the stabilizer and co.dopant. The PANI/P-PVA nanoparticles were characterized by transmission electron microsco.y （TEM）, Fourier transform infrared spectrosco.y （FTIR）, thermal gravimetric analysis （TGA）, X-ray diffraction （XRD）, electrical co.ductivity measurements and re-dispersion stability testing. All the results were co.pared with the properties of the co.ventional polyaniline in the emeraldine salt form （PANI ES）. It was found that the feeding ratio of P-PVA obviously affected the morphology, re-dispersion stability and electrical co.ductivity of the PANI/P-PVA nanoparticles. When the feeding ratio of P-PVA ranged from 40 wt% to 50 wt%, the PANI/P-PVA nanoparticles showed spherical shape with good uniformity, significant re-dispersion stability in aqueous media and good electrical co.ductivity.

An oil flow obtained from the Middle Ordovician Fengfeng Formation carbonate reservoir in the well KG-3, Kongxi burial-hill zone in 1993 marked a breakthrough in petroleum exploration of the high-mature Lower Palaeozoic strata, North China. Both the Lower member of the Fengfeng Formation and the Seco.d Member of the Upper Majiagou Formation in the Middle Ordovician are supposed to be the main source beds. Oil generation peaks range from 1.0% to 1.6% in Ro, showing a “lag effect” of oil generation in high-mature carbonate source rocks under multicyclic tectonic movement co.ditions. The Kongxi burial-hill zone adjoins a potential Ordovician source kitchen. The KG-3 Ordovician burial-hill reservoir has undergone two oil filling events, i.e., an early event in the Late Carboniferous-Permian and a more significant late event in the early Eogene.

The western Liaodong （辽东） Bay subbasin displays examples of segment, linkage of extensional fault, and fault-related folds. The Liaoxi （辽西） extensional fault system co.sists of a series of NNE- and NE-trending segments that were linked through relay ramps. The fault hanging walls are characterized by a series of en echelon synclines with axial traces sub-parallel to the faults. The synclines are doubly plunging located on the hanging wall of normal faults, with the strata dip sub-parallel to the fault. These folds result from along-strike displacement variations of the individual fault segments, as well as from extensional fault-related folding. In the study area, the synclines are separated by transverse intra-basin highs and relay ramps that formed where segment linkage occurred. These hanging wall synclines and their relation to fault displacement variations indicate that they are formed by extensional fault-related fold.
