胜坨油田不同含水期层间干扰规律

胜坨油田为整装多层砂岩油藏，储层层间非均质性严重，在油田开发的过程中，多层合采势必造成层间干扰，影响潜力层的发挥。利用各种生产资料、取心检查井、测井解释资料及精细油藏研究成果对不同开发阶段的干扰形式进行了分析，结果表明开发初期主要是稀油高渗透层干扰稠油中低渗透层；中含水期主要是高压高含水层干扰中低压含水层；高含水期初期主要是高压特高含水、高含水层干扰低压高含水、中低含水层，特高含水期层间干扰转变为特高含水韵律层干扰高含水及中低含水韵律层。该研究对胜坨油田及同类油田的调整和挖潜具有一定的指导意义。

Rule of interlayer interference in various water cut periods of Shengtuo Oilfield

Shengtuo Oilfield is an integral multi - layer sandstone reservoir with serious interlayer heterogeneity. During the development of such oilfield,commingling production would certainly cause interlayer interference,and the productivity of potential layers is also restricted. With the application of various data of dynamic production, coring inspection chamber,log interpretation,and results of fined reservoir research, interference forms at different developing phases are analyzed. It shows that thin oil and high-permeability layers interfere crude oil and medium - low - permeability layers in early oilfield development and high pressure and high water bearing layers interfere water bearing layers with medium-low pressure in medium water cut period while extra high and high water bearing layers with high pressure interfere high and medium-low water bearing layers with low pressure in high water cut period and rhythmic units with extra - high water cut interfere that with high and medium - low water cut in extra high water cut period. The results have certain guidance for adjustment and tapping potential in Shengtuo Oilfield and the same type of oilfields.
