  oil well
For northern Egypt and the Gulf of Suez, gradients were calculated from oil well bottom hole temperature data; east of the Nile, and at three sites west of the Nile, gradients were calculated from detailed temperature logs in shallow boreholes.
      
A constant wall temperature is applied after a certain height to mimic downhole conditions in an oil well.
      
Carbon dioxide evolution rate and dehydrogenase activity were matched with the degradation of diesel oil well.
      
It is demonstrated that seasonal tilts of the beds of rockers are associated with the thermal influence of the oil well during freezing/thawing of the surrounding soil, which results in curvature of the freezing and thawing fronts.
      
The land area "weighed" by a geological lysimeter increaseswith formation depth and it is speculated that recordings made at oil well depth may allowdirect monitoring of subsurface water mass changes at the regional scale.

This article is presented out of to the necessity of the acoustic logging of petroleum wells.The system is assumed to be a fluid cylinder surrounded by a uniform quasi elastic solid medium and the acoustic logging tool is simulated by a central rod with local vibrating surface.The two dimension fast Fourier Transform(FFT)algorithm is adopted.Sound fields in rocks of different properties using different source frequencies are calculated and the sound pressure waveform curves on a series of recording points are obtained.These curves clearly indicate the existence of four kinds of wave groups.The error of their calculated velocities is less than 4%.The characterestic attenuation curve is also given.The results of calculation show that the physical model is acceptable and the method of calculation and the computing program are reliable and thus provide a theoretical basis and an elegant method for holographic study of oil well logging.

本文是直接针对声法石油测井的需要提出的,假定体系为准弹性均质固体中的流体柱,测井声系用局部表面振动的中心圆柱模拟。采用二维快速Fourier变换(FFT)算法,对不同频率的声源在各种岩性下的声场进行了计算,得到了一系列记录点的声压波形曲线。这些曲线清楚地表明有四种波群存在,计算了它们的速度,误差低于4%;同时也给出了衰减特性曲线。 计算结果表明,物理模型是可取的,计算方法与程序可靠,为开展全信息测井研究提供了理论依据和有效手段。

Water content and density of hydrogen-rich material (mixture of oil, gas and water) in oil well are measured by a system consisting of a single probe and a radioactive source emitting two kinds of low energy photons with different energies and intensities. One core wire of a cable is used to supply voltage for the underground part of the instrument and at the same time to transmit signals from underground probe to signal processing system situated on the ground surface. The instrument gives values ofwater...

Water content and density of hydrogen-rich material (mixture of oil, gas and water) in oil well are measured by a system consisting of a single probe and a radioactive source emitting two kinds of low energy photons with different energies and intensities. One core wire of a cable is used to supply voltage for the underground part of the instrument and at the same time to transmit signals from underground probe to signal processing system situated on the ground surface. The instrument gives values ofwater content and density directly.The principle and structure of the instrument and block diagram of electronic circuits are given in the text and in situ experimental resultsare reported.

用单个放射性核素产生的强度不同的两种低能光子测量富氢物质(石油生产井中的油气水混合物)中的含水率和密度,仪器只用一个探头、一根缆芯供电并同时用它传输两种数据信号,信号经模拟计算装置运算后,直接给出含水率和密度的数值。 文中介绍了仪器的原理、结构、电路的方块图和现场实验结果。

An oil-well expansive cement containing an appropriate mixture of normal oil-wellcement, alumina cement, gypsum and bentonite was cured under various hydrothermal con-ditions and the mechanical, expansive and water permeability properties there of wereinvestigated. From phase analysis, it has been ascertained that the formation of monosulfo-aluminate hydrate was accelerated by increasing the temperature and by prolonging thecuring time. The mechanism of expansion of the cement was also discussed...
