坚硬致密“打滑”地层新型自锐金刚石钻头的研究

针对坚硬致密“打滑”地层研制了一种新型自锐金刚石钻头。室内微钻试验及现场钻进试验均表明:在钻进极坚硬致密“打滑”地层时,相对于普通金刚石钻头,新型自锐金刚石钻头可提高钻头机械钻速1～3倍,且钻头寿命相对较高,为攻克“打滑”地层提供了一种有效的碎岩钻进工具。     

关于我国金刚石钻头生产技术的分析研究

我国金刚石钻进取得了很大的成绩,但是其技术经济指标尚不理想,与国外相比尚有差距,特别是其中关键的金刚石钻头性能指标更是如此。我国目前主要使用热压烧结技术生产金刚石钻头。但是,热压烧结有“短板”,国外冷压浸渍烧结有强项,微波加热烧结有优点。建议试验研究冷压浸渍、微波烧结金刚石钻头,以便把我国的金刚石钻探技术经济指标提高到一个新水平。     

仿生孕镶金刚石钻头在漠河冻土区天然气水合物勘探钻进中的应用

仿生孕镶金刚石钻头具有高效、耐磨的特点,符合漠河天然气水合物勘探的要求及漠河钻探施工现场的条件。介绍了符合漠河地层特点的仿生孕镶金刚石钻头的设计与制造。同时对效果不理想的钻头的钻进情况进行了分析,提出了评价钻头性能时需要综合分析,从而客观、真实地反映钻头的实际钻进能力。漠河天然气水合物MK-2科学钻探试验井的钻进结果表明,仿生孕镶金刚石钻头的寿命比普通孕镶金刚石钻头长73%,钻速比普通孕镶金刚石钻头高22%。     

人造金刚石孕镶钻头磨损特征的研究

金刚石钻头定每转进尺钻进试验表明：在每转进尺合理范围内，钻头磨损率较低，在此范围外，则较高；并发现钻头多出现内喇叭型不均匀磨损唇面。本文从理论上解释了金刚石钻头出现这种磨损唇面的原因：即内侧金刚石切深、受力及每周碎岩体积较大；并据此探讨了包括镶钻头在内的金刚石镶嵌措施，以使唇面均匀磨损。     

Définition d'une limite multicritère ; stratigraphie du passage Campanien–Maastrichtien du site géologique de Tercis (Landes,SW France)Definition of a multi-criteria boundary; stratigraphy of the Campanian–Maastrichtian interval of the geological site at Tercis (Landes,SW France)

Lithostratigraphy, physicochemical stratigraphy, biostratigraphy, and geochronology of the 77–70 Ma old series bracketing the Campanian–Maastrichtian boundary have been investigated by 70 experts. For the first time, direct relationships between macro- and microfossils have been established, as well as direct and indirect relationships between chemo-physical and biostratigraphical tools. A combination of criteria for selecting the boundary level, duration estimates, uncertainties on durations and on the location of biohorizons have been considered; new chronostratigraphic units are proposed. The geological site at Tercis is accepted by the Commission on Stratigraphy as the international reference for the stratigraphy of the studied interval. To cite this article: G.S. Odin, C. R.

Late Wuchiapingian (Late Dzhulfian,early Late Permian) limestone olistolites within the Tertiary flysch of Glypia Unit (Mount Parnon,central–eastern Peloponnesus,Greece)

Some olistolites reworked in a Tertiary flysch of Mount Parnon (Peloponnesus, Greece) exhibit a Late Permian assemblage, dominated by Paradunbarula (Shindella) shindensis, Hemigordiopsis cf. luquensis and Colaniella aff. minima. This association corresponds to the Late Wuchiapingian (=Late Dzhulfian), a substage whose algae and foraminifera are generally little known. Contemporaneous limestones crop out in the middle part of the Episkopi Formation in Hydra, but they are rather commonly reworked in Mesozoic and Cainozoic sequences. The palaeobiogeographical affinities shared by the foraminiferal markers of Greece, southeastern Pamir, and southern China, are very strong (up to the specific level), and are congruent with the Pangea B reconstructions.
