摘要
2010年海上某复杂断块油藏由于过度开发和违规钻井造成严重溢油污染事故,该区块D、E平台均为海底溢油,没有监测到具体的溢油开始时间和初始溢油强度,溢油初期的统计数据分析其精度较低,这为准确测算海底溢油量带来巨大的困难。针对此溢油特点,基于该事故现有数据资料,通过油藏工程方法,对最大可能油藏的溢出原油量进行初步估算,通过计算认为该断块溢油规模应当大于1 000 m3,小于7 000 m3。
A complex fault block reservoir of offshore field cause serious oil spill accident due to over - exploitation and violation drilling in 2010. The D, E platform of this reservoir both are undersea oil spill. For no monitoring to the oil spill start time and initial oil spill strength, the initial spilled oil statistical data is very low based on empiri- cal analysis. This has brought great difficulties for the accurate calculation the oil spills volume undersea. In view of the D, E platform oil spill characteristics and current statistical data of this oil spill accident, it accords reservoir engineering method to get the calculating method to estimate the maximum possible volume of spilled oil. The cal- culation result shows that the volume of spilled oil from the fault block reservoir should be greater than 1 000m3, less than 7 000 m3.
