    This paper developed a non steady state theory for imperfect living polymerizations with various equilibria between active and dormant species giving expressions of various molecular parameters, such as the number and the weight average degrees of polymerization and the polydispersity index.

    This paper developed a non steady state theory for imperfect living polymerizations with various equilibria between active and dormant species giving expressions of various molecular parameters, such as the number and the weight average degrees of polymerization and the polydispersity index. The comparison of theoretical results of the non steady state approach with those of the stationary state assumption shows that numerical outcomes from both methods conform with each other except at the beginning of the polymerization if the rate constant of chain propagation is comparable with that of reactivity exchange between dormant and active species, and a big difference between the results of the two approaches was observed in the case of k p being much larger than k 1 or k 2.

    对各种两物种体系非理想活性聚合反应作了非稳态动力学分析,给出了各种分子参数在非稳态条件下的公式。数值计算的结果表明,在链增长反应速率比休眠物种和活性物种之间的相互转化速率大很多时,聚合反应不易达到稳态;当上述两种反应速率比较接近时,体系较快即能达到稳态,只有在反应开始的阶段,稳态和非稳态的理论结果有所差别。

    In order to make the conventional perm eability test device be effectively used for the permeability test of tight rock s,a certain improverment has been done on the dasis of the standard conventional device,by which the tight rock permeability can be tested by use of high press ure stationary flow method under the formation conditions simulated.In testing p rocess,the confined pressures demanded for the testing might be up to 30.0~60.0 MPa and pore pressures 5.0~15.0 MPa,and the permeabilites of less than 10×1 0 -5 μm 2 might be measured under such a high pressure.Meanwhile,the i nstantaneous pulse technique,a well developed vital method of measuring the per meabilities of low permeability rocks,was fully examined.Through contrast and a nalysis,it is found that the permeability value measured by the instantaneous pu lse method is very close to that measured by the improved conventional permeabil ity testing method.Because the instantaneous pulse method is based on unsteady state theory and the high pressure conventional testing on steady flow techniqu e,the two methods may be mutually repairable to make up deficiencies.Through a g reat number of experiments,it is proved that the relative error of the permeabil ity values measured by the two method is very small,the difference between the b oth being less than 10%.It fully proves that the improved conventional permeabil ity test device is of reasonableness.

    为了使渗透率常规测试装置更能有效地用于致密岩石的渗透率测试 ,我们在标准常规测试渗透率的实验装置基础上作了一定的改善 ,使之能够在模拟地层条件下进行高压稳流法测试致密岩石渗透率 ,在测试过程中 ,实验所需围压可以达到 30 .0~ 6 0 .0MPa ,孔隙压力可以达到 5~ 15 .0MPa ,并在这样的高压状态下测得的渗透率范围可以低于 10 -5μm2 。同时 ,引用目前发展较为成熟的一种测量低渗透岩石渗透率极有生命力的瞬时脉冲技术给予其充分的验证 ,通过相同测试条件下的瞬时脉冲测试方法的对比分析 ,发现两者所测渗透率值非常接近。由于瞬时脉冲法基于非稳态理论 ,而高压下的常规测试则是基于稳流技术 ,所以 ,两种方法可以互相弥补 ,取长补短。经大量实验证明 :这两种方法测得的渗透率相对误差极小 ,两者误差通常小于 10 % ,这一事实充分论证了改进的渗透率常规测试装置具有合理性。
