松辽盆地南部深层火山岩识别及成藏条件分析

松辽盆地北部徐深1井在营城组火山岩获得油气突破后，在松辽盆地南部长岭断陷针对火山岩部署了长深1井。在长深1井营城组火山岩地层测试获4.6×105m3/d的工业气流，推算无阻流量1.5×106m3/d以上，预示松辽盆地南部深层火山岩气藏是下步勘探开发的主要领域。通过大量的火山岩岩心资料，利用岩石学、矿物学、测井和地震地层学等多学科技术，首次在松辽盆地南部建立了火山岩识别标准，在东南隆起区部署探井1口，在火山岩中见到了较好的气显示，取得很好的效果。     

正确选择气顶油藏高效开发模式

通过对不同类型气顶油藏的油气水分布特征及气顶和边水能量的研究分析，计算水侵量与边水体积及合理的弹性产率。提出适合气顶油藏特点的开发模式是先开采油区后开采气顶，并以唐家河油田港深18—2断块为例，证明采用该模式可以高效开发气顶油藏。图3表1参6

Experimental Study on the Effect of Steel-fibre in Conerete Thick Cap

The effect of steel fibre used in concrete was systematically analyzed by model testing of 30 2-pile thick caps of steel-fibre reinforced concrete, in which the model scale was 1：5. The experiment system composed of a loading device, strain measurement system and a data-acquisition system was used, also an electromechanic centigrade scale, a lens and a Y J-25 static resistance strainometer were used.The experimental results show that the volumetric rate of steel fibre and draw ratio have an important influence on its load-bearing capacity. The incorporation of steel fibre can effectively improve the extension and reduce the thickness of the caps.     

Stress State of Bent Buried Pipelines

The authors consider edge effects in buried pipelines that occur in the region of joining of a straight buried pipe and a bent insert (factory bend, elbow, or an elastically bent segment). The action of those effects results in the appearance of additional bending moments, which are proportional to the difference between the axial force in an infinite straight pipeline and that in a closed-end pipe, and depend on the geometrical parameters of the pipeline and physical-mechanical characteristics of the soil. Specific examples of analysis of elastic interaction of a pipeline with the soil for pipe bends with various radii of the bend arc are offered. It is shown that additional bending stresses may exceed appreciably the stresses from the axial force, and therefore, they should be taken into account when designing and building pipelines. The solution for an elastically bent segment has been obtained and analyzed.
