The performances of SiO2+ SDS foam system were investigated by using Warning Blender method,through which the optimum amount of SiO2 nanoparticles was determined. And the influences of temperature and salinity on foam properties were studied as well. The plugging ability,diversion ability,and oil displacement performance for SDS and SiO2+ SDS foam systems were characterized and compared by means of the core displacement experimental facilities. Also the microscopic visualization test was conducted to compare the oil displacement performance of water flooding,SDS and SiO2+ SDS foam systems on the dead-end pores. The results show that SiO2+ SDS foam system is more stable than SDS foam system,which can significantly improve the plugging,diversion,and oil displacement ability. Also the displacement effect for dead-end pores is increased as well.

Based on the field data of horizontal directional drilling(HDD) project,theory analysis and sample testing were used to deduce calculation formula of plastic radius in HDD borehole.The testing results were analyzed.The results show that,when the pressure difference is zero or ground pressure is larger than slurry pressure,plastic radius tends to be a constant with little change.When pressure difference is less than 1.0 MPa,plastic radius increases exponentially with the increment of drilling fluid penetration.When pressure difference is more than 1.0 MPa,plastic radius shows an exaggerated range beyond the penetration radius.

The adsorption of anionic surfactant of sodium dodecyl sulfate(SDS) onto preformed particle gel(PPG) and the effects of SDS on the swelling ratio of PPG were combined.The effects of anionic surfactant sodium dodecyl sulfate on the rheology of preformed particle gel were also studied by using steady shear and oscillatory shear rheological experiments.The interaction mechanism of SDS and the rheology of preformed particle gel was discussed.The results show that the adsorption of SDS increases and the swelling ratio of PPG first decreases and then keeps stable with the increase of SDS.The preformed particle gel exhibits shear-thinning property and its viscosity is significantly influenced by SDS at lower shear rate.With the increase of SDS concentration,the yield stress of the preformed particle gel decreases and the storage modulus first decreases and then increases.

Based on the geochemical research of mudstone and oil shale of Huadian formation, the productivity of Eocene Paleo-Huadian lake was qualitatively and quantitatively recovered by using the organic carbon method, and the water environments, paleoproductivity change during the lake evolution and enrichment mechanism of organic matter were discussed. The results show that the evolution order of paleoproductivity in Huadian Basin is middle oil shale member, upper coal member and lower pyrite member. The highest paleoproductivity achieves at 1 033.09 g/(m·a) during the sedimentary period of middle member of Huadian formation. The ancient lake is in eutrophic state. The bacteria and algae are dominate in organic matters and the lake water is in steady hypoxic and fresh-brackish reduction environment during this stage, which reflects that the high paleoproductivity is mainly contributed by algae and directly influences the origin and abundance of organic matters. The alternative salinity change of lake water makes the bottom water be in a steady hypoxic environment, which is a favorable environment for organic matter conservation. The lakes during the lower member and upper member of Huadian formation are in obvious mesotrophic state and fresh hypoxic environment, and the average paleoproductivity is 143.82 g/(m·a) and 153.26 g/(m·a) respectively. High paleoproductivity is the first condition for organic matter enrichment of oil shale, and steady hypoxic environment in bottom water is the most favorable environment for organic matter enrichment.

A new algorithm based on B-splines was proposed to consider the rate measurement error during pressure deconvolution.Several methods were provided to determine the actual rates for each flow period,which can be utilized to determine the actual pressure response in turn.The results show that unit-rate pressure response with 10% rate error agrees well with the true results,which is much better than that from ILK model.The new algorithm can overcome the effect of rate measurement error on the pressure response.
