The geothermal reserve is evaluated in Early Tertiary Oligocene, the geochemical character is analysed and the fluid quality is appraised in the well Tang 20-2, at last, some relevant advices are brought forward to geothermal exploitation and utilization.

并对已经开发古近系东营组地热井塘20-2井进行了单井储量评价、地热水地球化学特征分析和流体质量评价，并评述了塘20-2井地热开发利用的环境影响提出了相应的防治建议。

Sequence in the third middle member of Shahejie Formation in a well of Shengli oilfield, the SP data were processed by two-scale wavelet transform using quadric spline wavelet. With this transformation the logging data were expended from one dimensional depth space into two dimensional depth-scale space and wavelet coefficient curves on different scales were obtained.

以胜利油田某井沙三上亚段第Ⅲ层序为例，选用二次样条小波，对该井段SP测井数据进行二进小波变换，将一维测井数据拓展为二维深度－尺度空间，得到不同尺度上的小波系数曲线。

The period of Wolabo Formation deposition is featured by relatively broad in geomorphology, far away of the source areas, less in proximal fan deposits, and well developing in ooid limestone and stromatolitic limestone.

乌拉泊组和井井子沟组以滨浅湖粉细砂岩、泥岩夹厚层砂岩沉积为主，沉积物中有机质含量低，实体化石稀少，但是遗迹化石丰富，属富氧湖泊。

Based on the core, slice observation, geology logging, log and seismic data from more than 15 typical wells, combined with the data of the adjoining area, through macroscopical and microcosmic study and according to the analysis of the kinds and characteristics of the rock components, four types of the sedimentary facies of the study area have been recognized, including Carbonate Platform, Continental-shelf, Slope and Basin. Furthermore, sunken platform, open-shelf and rimmed-shelf have been recognized for the first time.

通过对研究区15余口井岩芯的精细观察，结合薄片鉴定、录井、测井、地震资料及区域沉积资料的分析，应用宏观和微观研究相结合的手段，在岩石结构组分类型及特征分析的基础上，识别并阐述了轮南古隆起奥陶系碳酸盐岩的四种沉积相类型：碳酸盐台地、陆棚、斜坡和盆地，并首次识别出了沉没台地、开阔陆棚和镶边陆棚等相类型。

On the basis of the results of survey and study about researches of pulse well test at home and abroad, the method of total pressure history match and numeric solution is selected as an advanced research, the goal is to investigate a method of pulse well test in theory and analysis under the conditions of no knowledging about the changing tendency of formation pressure and having outer boundary.

根据对国内外关于脉冲试井研究情况的调研结果，本文选择全压力史拟合方法和数值求解方法作为一个探索性研究课题，将有限元法应用于压力的数值求解过程，目的是探索一种在地层压力变化趋势不清楚和有外边界的条件下的脉冲试井理论和分析方法，从而为油田提供结果更准确的、信息更丰富的开发调整依据资料。
