The Conditions for determining chromium in human hair .by GFAAS.and a new method for digesting human hair have been studied. The conventional complete digestion method may result in the loss of chromium. A new method is proposed to form a suspension by soaking the hair with HNO_3,adding surfactant to stabilize the colloid and then chromium content in the suspension solution is determined. The results are satisfactory. This method is simple and rapid, with recovery of 93~98% and high sensitivity.

Water lock effect is a problem generally existing in the course of oil-gas producing. It is specially outstanding in the tight reservoir with drilling fluid, acidizing and fracturing fluids. The reason for producing water lock effect is analysed in theory according to the model of the bunde of capillary tubes. it is verified by permeability recovery experiment that the capillary tube force of extraneous fluids in oil-gas formations is the main factor of controlling water lock effect. Practical operation shows that only adding surfactant can the water lock effect of well completing fluid be reduced; But it is wrong that all additives reducing surface tension can reduce water lock effect, some one even leads to just the opposite;The influence of contact angle and capillary tube's effective radius must be considered.

水锁效应是油、气层开采过程中普遍存在的问题,并以钻井液及酸化、压裂液对致密储层的水锁效应尤为突出。前人对这些问题均有论述,但理论分析不够,至于引起水锁效应的原因及其影响因素迄今尚无统一看法。文章根据毛细管束模型,从理论上分析了产生水锁效应的原因。指出外来流体在油、气层中的毛细管力是控制水锁效应的主要因素,并用渗速率恢复试验加以证实。实际工作表明,要降低完井液的水锁效应必须加入表面活性剂,但不是凡能降低表面张力的添加剂均能降低水锁效应,有的甚至适得其反。文章认为决定水锁效应的主要因素是毛细管力,而表面张力只是影响毛细管力的一个因素,此外还必须考虑接触角和毛细管的有效半径的影响。
