The Study of the Controlling Factors of High Efficient Well

It came into the development stage of the high water cut and high degree of reserve recovery in Pu-bei oilfield.The distribution of remaining oil was complicate and scattered,which was affected through-going characteristic of sand body,as a result,it was an active method of tap the latent power remaining oil that looking for high efficient wells and controlling factors of high efficient wells were studied and analyzed in concentration area of remainder oil saturation.Through studying the conditions for the formation and distributed trait of high efficient wells in Pu-bei oilfield,and making use of all sorts of reservoir parameters and operational parameters which were applied,the genetic model of high efficient wells was established.The method is feasible and reliable through practical verification.It provides technique and theory support for further tapping the latent power remaining oil.
