After crystallization basement was formed in Tai Shan group in the end of Archaean, it suffered long term denudation and deposited to marine and land interbedded formation with stable lithology and thickness. Buried Hill is a large size fold nappe which was uplifted, compressed, folded, denudated and settled in Indosinian period, deposited in Mesozoic formation, then wholly advanced to the west in the late of Yan Shan movement. The force acting on internal structure of buried hill was complicated, and fault block was broken up.

本文通过物探、测井二次解释和钻井等大量资料的研究认为：桩西古潜山在太古代末期泰山群形成结晶基底后，遭受长期剥蚀，在古生代沉积一套岩性、厚度稳定的海陆交互相地层，是一个经印支期抬升、挤压、褶皱、剥蚀、沉降接受中生界地层沉积之后，在燕山运动后期，整体向西推移的大型褶皱推覆体。

On the basis of the test results and site investigation, the chemical clogging mechanism was analyzed. Ferric mineral in the stratum is deoxidized.

针对长江堤防典型的地层砂样，采用砂砾石和聚氨酯作为反滤料，利用葡萄糖溶液模拟地层中的还原条件，开展了反滤试验；并结合对实际减压井运行的观察，分析研究了化学淤堵的机理。

In this paper, the level of resolution reduction caused by Earth′s absorption wane and the compensation effect of the spectral equilibrating filter to the high frequency signal are studied by the method of computer...

Test results show that the agent can be frothed in the strata, with the volume three or four times bigger. It can also be forced to the deep strata to form stable and high strength frothy gel, so as to control the profile in deep strata.

实验结果表明，该调剖剂可在地层发泡（体积可增大3~4倍），并被推向地层深部形成稳定的、高强度的泡沫凝胶，可起到深部调剖的作用。

Formation damage can be minored by using CO2 foam fracturing fluid as it has low filtration, high flowback and good compatibility with formation fluids.

由于CO2泡沫压裂液具有滤失量低、返排能力强、与地层流体配伍性良好等优点，采用CO2泡沫压裂技术，可减小压裂液对地层的伤害。

The main fruits and cognition are as follows:1 .On the base of collecting and neatening some data about this area, using sequence stratigraphy theory and the traditional method of cycle correlation, combining core observation with well log interpretion, set up subtle stratum contrasting framework section, and Chang-6 formation is divided nine substratums from top to bottom.

本次研究所取得的主要成果及认识有： 1、在对研究区已有取心井段的相关资料进行收集与整理的基础上，应用层序地层学理论与传统沉积旋回小层对比方法，结合岩心观察与测井解释，建立以小层为单位的精细地层对比骨架剖面，将研究区长6油层组自上而下细分为9个不同级别的小层。

The program compile with BASIC language and O'NILLs filter coefficient can be used for forward calculation with the gived model.with the input of the observed data and the assumeed model,one can obtain the observed curve and calcula- ted curve in the Same dual logarithm coordinate.

该程序是根据 ONILL 的滤波系数，利用BASIC 语言编制的。它根据给定的地层模型可作正演计算。输入野外观测值以及所假设的地层模型便可在同一个双对数座标中绘出观测曲线和计算的曲线。

The result shows that when in-place oil with its viscosity higher than 1.0mPa·s percolates through reservoir rocks with permeability less than 1×10~-3 μm~2, both have start-up pressure gradient, and it increases with the decrease of rock permeability and increase of crude oil viscosity, as oil wettability of the rocks increas...

结果表明，粘度大于1·0mPa·s的地层油通过渗透率小于1×10-3μm2的地层岩石渗流时，均具有启动压力梯度，且启动压力梯度随岩石渗透率的减小和原油粘度的上升而增大；岩石的亲油性增强，启动压力梯度增大；含有束缚水的岩样的启动压力梯度大于不含有束缚水的岩样。

Each formation will create different effects on the wellbore due to the paraffin content, depth and formation porosities.

由于石蜡含量，井深和地层孔隙度的不同每个地层都会对井筒产生不同的影响。

According to this scheme, the Longmaxi Formation is only referred to as the black siliceous and carbonaceous shales at the base of the Silurian strata. All the carbonate rocks above it have been redelineated and redivided into new lithostratigraphic units.

新方案除对志留系底的黑色硅质碳质页岩沿用龙马溪组这一岩石地层单位名称外，其上的碳酸盐岩均重新划分和建立了新的岩石地层单位，并确定其涵义和时限标准。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
