深层碳酸盐岩储层酸压改造的目的就是让酸压裂缝与天然缝洞系统沟通。根据酸压改造施工曲线变化模式和酸压改造后的地质效果 ,提出了 4类评价体系 ,每种体系对应一种酸压模式 ,包括未压开地层 (Ⅰ类 )、压开地层即行停止 (Ⅱ类 )、压开地层未与缝洞沟通 (Ⅲ类 )及压开地层并与缝洞沟通 (Ⅳ类 )的酸压模式。利用此方法对塔河油田 2.7口井的酸压改造情况进行了分类评价 ,5 6 %的井达到了Ⅳ类酸压模式 ,既压开了裂缝又实现了与天然缝洞系统的沟通 ,油井能保持较长期的高产稳产 ;2.2.%的井达到了Ⅱ和Ⅲ类酸压模式 ;其余 2.2.%的井只达到了Ⅰ类酸压模式 ,此类油井的酸压效果有待进一步改善。

The front of the Zoulang Nanshan Caledonian volcanic island arc zone in the northern Qilian Mountains is a forearc accretionary terrane, composed of multiple accretionary volcanic island arcs, flysch accretionary wedges,high-pressure metamorphosed detachment zones and remnants of ophiolites. It resulted from the northeastward subduction of the Early Palaeozoic Qilan oceanic crust beneath the Alxa block. High-pressure metamorphism, which occurred during the subduction, progressed through three stages: the initial stage of medium T-high P,the main stage of temperature decrease and pressure increase, and the lag stage of pressure decrease and temperature increase. Finally the paper presents a retrotrench subduction dynamic model indicative of northward subduction of the central Qilian block and southward accretion of the Alxa block during the period of 450-500 Ma.

The Sichuan-Xizang Railway is an important part of the railway network in china, and {1. disasters, such as mountain floods and landslides, frequently occur in this region. Precipitation is an important cause of these disasters;therefore,accurate simulation of the precipitation in this region is highly important. In this study, the descriptions for uncertain processes in the cloud microphysics scheme are improved;these processes include cloud droplet activation, cloud-rain autoconversion, rain accretion by cloud droplets, and the entrainment-mixing process. In the default scheme, the cloud water content of different sizes corresponds to the same cloud droplet concentration, which is inconsistent with the actual content;this results in excessive cloud droplet size, unreasonable related conversion rates of microphysical process(such as cloud-rain autoconversion), and an overestimation of precipitation. Our new scheme overcomes the problem of excessive cloud droplet size. The processes of cloudrain autoconversion and rain accretion by cloud droplets are similar to the stochastic collection equation, and the mixing mechanism of cloud droplets is more consistent with that occurred during the actual physical process in the cloud. Based on the new and old schemes, multiple precipitation processes in the flood season of 2.2.1}along the Sichuan-Xizang Railway are simulated, and the results are evaluated using ground observations and satellite data. Compared to the default scheme, the new scheme is more suitable for the simulation of cloud physics, reducing the simulation deviation of the liquid water path and droplet radius from 2.times to less than 1.time and significantly alleviating the overestimation of precipitation intensity and range of precipitation center. The average root-mean-square error is reduced by 2.%. Our results can provide a scientific reference for improving precipitation forecasting and disaster prevention in this region.

The Indosinian alkaline complexes in northern Hebei Province are distributed along the two deep faults striking in an approximately east-west direction. These alkaline complexes arc divided into three rock associations: （1. pyroxene diorite-quartz alkaline-feldspar syenite-alkali-feldspar granite-syenite- aegirine-augite syenite-alkali-feldspar granite, （2. pyroxenite-biotite pyroxenite-magnetite apatitic rock -syenite; （3） nepheline syenite-unite-aegirine-augite syenite-ijolite. The former one occurs along the north deep fault, and the latter two along the south deep one. From north to south, the alkaline complexes increase in alkalinity and decrease in the contents of SiO2. Their geochemical characteristics show that the first rock association originated from the transition zone between the crust and the mantle, whereas the latter two originated from the replaced mantle. Their magmas experienced different evolutional processes. These alkaline complexes were resulted from the collision between the Sibrian plate and the Sino-Kerea plate at the end of Hercynian period.
