  low permeability
However, a large volume and high energy consumption are needed in biotransformation, while the low permeability and stability must be solved in the membrane process.
      
For low permeability membranes, instability with respect to monotonic finite-wavelength perturbations is characteristic.

It is proposed that low permeability of plasma membranes to water in fraction-I seeds results from the predominantly closed aquaporin channels, whereas a higher permeability of weak seeds (fraction II) is due to open channels.
      
Increased magnesium concentration in the secondary cardioplegia did not provide additional benefit to the ischemic myocardium, possibly due to the low permeability of the sarcolemmal membrane to magnesium.

Aiming at the character that gas well isochronal testing consists of many drawdown and build-up cycles, the flowing and build-up pressures are regarded as contunuous action process. According to the superposition principle, the formula of dimensionless pseudopressure is derived,the new comprehensive interpreting typical curve is developed, and its character is discussed. It is illustrated that the new way is easy to explain early stage pressure data,and remove non-unique of matching to improve interpretation...

针对气井等时试井一般由多个开关井测压周期组成的特点,将每个测压周期流动压力和恢复压力看成是连续作用过程。根据叠加原理,得到了测压周期的无量纲拟压力表达式,研制了新型综合解释典型曲线,讨论了典型曲线特征。用实例解释说明了新型典型曲线拟合法的应用步骤,表明该方法不仅易于解释早期压力资料,而且能消除拟合的不唯一性,可提高解释精度。此研究工作对于低渗透致密气藏试井解释具有重要的实际意义。

The characteristics of low porosity, low permeability,high water saturation and complex minerals of dolomite gas reservoirs cause log resPOnses confused and log interptetutions with several possibilities. A new log interpretation model is formulatEd. its distinguishing features are that a reservoir is treated as two pertS of solid and liquid, separating framework from shallness. dividing effective porosity into two types of gas-bearing and water-bearing ; only porosity logs and .natural gamma ray log take part in the optimizing process, no resistivity log is included ;the reservoir is radially divided.into several zones by its mud-filtrate invasion profile and these zones are interpreted serrately. Suited to the model, an optimal algorithm with flexible tolerance is employed. It permits that,within the error margin and intermium solution may not correspond to the assumed conditions, but it as advances toward the optimum, this error margin is becoming more and more narrow till at last the solution convetges to the optimum one. The algorithm has a wide application. It can work even when the objective function is not a standard one and it depends little on an initial solution. Through processing the log data of over 10 wells from the dolomite gas reservoirs in the central part of Shanganning Basin and compering the resultS and experimental data with those processed with oversea software, satisfactory results are obtained.

低孔隙白云岩气藏以孔隙度低、渗透率低、含水饱和度高和岩石矿物成分复杂为特征,这些因素导致测井响应的模糊性以及问题的多解性。文章提出一种新的测井解释模型,其特点是:地层分为固体与流体两大部分,骨架与泥质分开,有效孔隙分为含气、含水孔隙度;只用孔隙度测井与自然伽马测井信息构成优化解释的响应方程组,电阻率测井不参加优化;地层按泥浆径向不同侵入深度分带进行优化计算。根据这一模型,选择可变误差多面体法作数学处理,它允许在一定的误差范围内,中间解可以不满足约束条件,并随着接近于问题的最优解,这个误差范围就越来越小,最后收敛到最优点。该算法适应范围广,即使函数的性质很差时,仍然可以得到比较可靠的结果,并且其结果对初值的依赖性弱,稳定性强。对陕甘宁盆地中部低孔隙白云岩气藏的十余口井测井资料进行了解释处理,其结果与实验数据和国外测井软件作了对比,取得了满意的效果。

It is still a tough problem how to predict the low-permeability thin-interbedded reservoir. This paper presents a practical reservior calibration method for low permeability thin-interbedded areas.The method can be used to determine the relationship of sand sections and high-resolution seismic phases. Four sand sections can be recognized for F oil-bearing formation of impedance section. This is done segment by segment on GeoQuest workstation. Oil-bearing patterns are constructed using patern recognition techniques which are supervised by drilling and logging data and further predict oil-bearing area. An area of thousands of square kilometer and a geological reserve of hundreds of million tons have been predicted.Seven wells have been drilled in the predicted area, all of which flow oil of commercial interest.

如何进行低渗透薄互层的储层预测,目前还是个难题。本文摸索出了一套在低渗透薄互层地区可行的储层标定方法,建立了砂岩集中段与高分辨率地震相位的对应关系。在波阻抗反演剖面上将F油层划分成四个砂岩集中段。利用GEOQUEST工作站,分段进行了砂体和物性预测。还利用模式识别技术及已知井资料建立含油模式,进行含油面积预测。经上述工作,预测含油面积×××平方千米,地质储量××××万吨。在预测含油面积范围内钻探7口井,均获工业油流。
