枣南孔一段注水外溢的定量计算

Quantitative Calculation of Injection Overflow in Zaonan kongyi Section

针对枣南孔一段油藏的注水外溢现状,采用油藏工程方法,定量计算出该油藏的注水外溢量;采用物质平衡方程,分单元计算出外溢注水量,进而求出外溢量中的有效部分和无效部分,结果表明,枣南孔一段油藏的注水外溢量绝大部分为无效注水外溢量。根据注水外溢井外溢量的大小,制定了相应的治理措施,取得了显著的效果。

The purpose of this paper is to solve overflow while injecting water in Zaonankongyi section. The reservoir engineering method is emp loyed to calculate quantitatively the overflow of injection; the material balanc e equation to calculate it by unit and thus determine the valid proportion and t he invalid one of it. Calculation results show that most overflow is invalid. I n addition, the corresponding measures are also established and make remarkable results by the overflow.
