With consideration of start up pressure gradient and media deformation, this paper studies vertical well production in low permeable reservoirs.
考虑启动压力梯度和介质变形的影响,研究低渗透油藏中直井产量的变化规律。
It is indicated that the main factors affecting low permeability gas reservoir are stress action, start-up pressure gradient, permeability, slippage effect, and water blocking effect etc.
结果表明影响低渗气藏的主要因素有应力作用、启动压力梯度、渗透率、滑脱效应、水锁效应等。
The method can be used to calculate the the end time of effect of wellbore storage with start-up pressure gradient considered.
该方法可用于考虑启动压力梯度影响的低渗透气藏气井井筒储集效应结束时间的计算。
This piston is being brought out, so we expect 0 the work to be negative, negative. And we start o V2 ut with zero volume. We end up with a volume p2 of V2, and the external pressure is constant to p2.
所以我们可以想象功是负的,开始的时候体积是,最终的容积是,外界的压力恒为。
Let's say we start from some V1 and p1 here, so high pressure, small volume and we end up with a high volume low pressure, under constant temperature condition.
例如我们要从压强比较高,体积比较小V1,p1出发,到达低压强,大体积的末态,过程中温度不变。
