摘要根据地震波动力学，建立了地震记录和测井数据间的合理的非线性映射关系，通过获取地震记录的自回归系数、分形维数、最大Lyapunov指数和突变参数，得到了声波时差和地层密度测井曲线，建立了地层弹性参数、强度参数的获取方法。

Recently, a nearly E-W-striking, over 10 km long albitite zone has been recognized for the first time in the Lower Silurian Meiziya Formation in a Lower Paleozoic lead-zinc ore deposit concentration area of the Xunyang basin, South Qinling. It shows a conformable contact and gradational relationships with the country rocks and has thick-bedded and massive, banded, brecciated structures and fine and very fine equigranular and intraclastic textures. It is chemically characterized by enrichment in SiO2, Al2O3 and Na2O and is rich in the trace elements Fe and Mn and poor in the trace elements Co, Ni and Cu. Its ∑REE, LREE and HREE are lower than those of the country rocks and exhibit pronounced Eu depletion.

最近，在南秦岭旬阳盆地下古生界铅锌矿集区内的志留系梅子垭组地层中首次识别出一条近东西方向延伸长达10余千米的钠长石沉积岩带，与地层整合产出，渐变过渡，厚层块状，条带状，角砾状构造，均粒微-细晶结构，内碎屑结构；其化学成分以富含SiO2，Al2O3及Na2O为特征，富Fe，Mn，贫Co，Ni，Cu等微量元素；该钠长石岩的∑REE，LREE，HREE均较围岩偏低，具明显Eu亏损的特征。

Cross-dipole Acoustic Logging is the best measurement of the formation wave-slowness,amplitude and attenuation coefficient of the compressional,shear and Stoneley wave types that may occur in array acoustic waveform data.Further more,it has special superiority in the evaluation of shear-wave azimuthally anisotropy.

0引言在柴达木盆地交叉偶极子声波测井主要有以下方面的用途：纵横波、斯通利波的提取，地层各向异性分析和斯通利波渗透性分析，并且可以根据地层岩石动态力学参数的计算方法进行储层动态力学参数的计算和估计，指导工程施工。

The lithologic characters changed from fluviolacustrine sandstone to aeolian Red Clay with thin interval of greyish-white sand layers at the depth of 602 m. It can be inferred from the rock strata and age that the development age of aeolian sequence in Lanzhou area was 7 Ma at least, which is in accordance with the bottom age (7~8 Ma) of the aeolian sequence of the eastern and central Loess Plateau, suggesting that their accumulation processes are unitary.

皋兰山剖面深度602 m处出现由河湖相砂岩向以风成红粘土为主常夹有薄层砂岩的地层转变，通过岩性地层及年代的推断，兰州地区的风尘序列堆积发育的年代至少为7 Ma，与黄土高原风尘序列堆积底界8～7 Ma基本一致，说明了兰州地区与黄土高原在风尘序列堆积过程中具有统一性。

It always contains fractures、 poorly cemented or non- cemented fracted zone in real formations, moreover, some fractures are induced during drilling, so the formation around the well is not continuous.

实际地层本身含有裂缝、胶结差、甚至无胶结的破碎带，再加上钻井过程中的诱导裂缝，井眼周围的地层并不是连续的。

Five types of traps, including compressional, extensional, shearing, gravitative and strata litholoical types, were divided on studying the feature of different tectonic movements , seismic sequences and depositional property in Wan an Basin.

作者在分析该含油气区地质构造特征、地层划分和沉积特征的基础上，划分了压缩型、伸展型、剪切型3 种构造类圈闭和重力、地层－岩性两种非构造型的圈闭，并选用南、北两条典型地震剖面模拟了典型圈闭形成过程及其与构造运动之间的演化关系，可为在该区中寻找同类型含油气圈闭和进行构造演化史的研究提供可靠依据。

Synchronous parallel-type refers to the oil-gas system formed a relatively independent oil-gas system in the same stratigraphic range. Heterochronous polymeric-type refers to the stratigraphic and regional range overlaid in oil-gas systems which formed in different period. Synchronous cross-type refers to a mode of regional ranges crossed of two oil-gas systems.

同期并列式指含油气系统在同一地层范围形成彼此独立的含油气系统；异期叠合式是指不同时期形成的含油气系统地层范围，地区范围重叠的组合方式；同期交叉式是指两个含油气系统地区范围交叉的组合方式。

In addition, it is one important basic research for exploration and development of lithologic oil and gas reservoirs in deep-water areas.

深水细粒沉积层系的层序地层单元细分和对比，是建立合理的层序地层格架的关键，也是进行深水区岩性油气藏勘探开发的一项重要基础研究工作。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
