多层合采砂岩油藏动态干扰及其影响因素

多层合采砂岩油藏中分部的含水率过高的话,那么多层合采沙岩油藏的干扰系数直线的上升。但是随着多层合采砂岩油藏生产压差增大其中低含水期也会随之减小,那么相反随着生产压差增大高含水期也会随着渗透率的降低而随着降低。从我国油井卡层及周边注水井分层调配后产生的动态干扰因素进行分析,并确定油井含水率达到什么标准才可以使周边注水井继续的进行分层调配。

Dynamic interference and influencing factors of multi-layer combined production sandstone reservoir

if the water content of parts in multi-layer sand reservoir is too high, the interference coefficient of multi-layer sand reservoir rises in a straight line. However, with the increase of production pressure difference in multi-layer combined production sandstone reservoir, the low water cut period will also decrease, on the contrary, with the increase of production pressure difference, the high water cut period will also decrease with the decrease of permeability. In this paper, we mainly analyze the dynamic interference factors after layered allocation of oil well sticking layer and surrounding water injection wells in China, and determine what standard the water cut of oil wells can reach to make the surrounding water injection wells continue layered allocation.
