Negative ions' height profiles from 20 km to 41 km measured during the recent two balloon flights over south Prance (44°N) are published. Therrnochemical constants △G, △H and △S for some sulphuric acid cluster ions are inferred from the in situ ion composition measurements. The chemical contamination during ascent leg measurements is revealed to be caused from the ion chemical reactions involved in the reeva-poration of water vapor from balloon surfaces.

A new numerical mondel is given for the calculation of wellbore temperature distribution. A comparison between the calculated value and the actual wellbore temperature in two wells shows little difference. This paper also suggests a new numerical model which is useful in designing vertical fracture for deep wells with high BHT. The interrelationships among fluid temperature in fracture, fracturing fluid flow behavior, fracture geometry and proppant transport are considered and injection by stages of fracturing fluids with different viscosity is simulated. It is possible to determine the length and the width of the fracture and fluid temperature in the fracture at any time, to determine both the suspended and the settled height profiles of proppant in the fracture. Variation of proppant concentration in a segment of slurry can be traced, and sandout fracture can also be predicted. The computer program provides a numerical method for calculating the performance of injection by stages and helps to find out a better fracturing program.

本文改进了井筒温度的现行计算方法,建立了新的数值计算方法和计算程序,使其计算更加实用方便。与现场实测结果的比较表明,计算值与实测值吻合较好。文中还提出了高温深井垂直裂缝压裂设计的数值方法并由此编制了计算程序。对综合考虑裂缝温度、压裂液流变特性、裂缝几何尺寸及支撑剂运移沉降的相互作用和影响进行了尝试,并模拟了地面分段变粘度注液压裂工艺。可以计算不同时刻的裂缝长度、宽度、缝中液体温度分布以及不同时刻缝中支撑剂的悬浮和沉积剖面,能追踪各混合液段中支撑剂浓度随时间的变化,对是否会出现缝中支撑剂堵塞等提供参考预测,有助于寻求较好的压裂设计方案。计算结果符合理论分析。

Under the condition of an unstable, inhomogeneous and anisotropic ionosphere, some relations among the dynamic parameters of the ionosphere and the observables of HF radio echoes reflected from the ionosphere are derived from the general ray equations. On the basis of these relations, a method is proposed to invert the height profile of the electron density, N(Z), and the height profile of the normal velocity, V(Z) of the constant electron density surface from the observed Dopplionogram, gonionogram,...

Under the condition of an unstable, inhomogeneous and anisotropic ionosphere, some relations among the dynamic parameters of the ionosphere and the observables of HF radio echoes reflected from the ionosphere are derived from the general ray equations. On the basis of these relations, a method is proposed to invert the height profile of the electron density, N(Z), and the height profile of the normal velocity, V(Z) of the constant electron density surface from the observed Dopplionogram, gonionogram, ionogram and rangionogram. Furthermore, comparing the possible combination of the radio wave obserables which are necessary and sufficient for the determination of the height profiles of V(Z) and N(Z), the authors suggest a new operation mode of ionosonde to observe the large scale ionospheric disturbances such as the gravity waves from a single station. This may be the theoretical basis for data analysis and instrumental improvement of modern ionosonde.
