平湖油气田作为东海海域第一个投入开发的油气田,开发至今已三年有余,原油于1998年11月投产,天然气于1999年4月投产,目前已有7口油井(其中定向井4口,水平井3口)生产,截止到2002年6月底,累计生产原油247.2×104m3,天然气11×108m3(包括油藏伴生气),凝析油18.7×104m3,原油采出程度23.6%,综合含水61%,天然气采出程度8.3%,平均年产量在50×104t以上,采油速度始终维持在7%以上。回顾三年来的开发历程,既有成功经验,也有失败教训,为东海的进一步开发提供和积累了宝贵的实践经验。

Pinghu oil &gas field, the first developed field in the East China Sea, has been developed for 3 years.It started to produce crude oil in November 1998 and natural gas in April 1999.At the end of June, 2002, the field included 7 oil wells (4 direction, 3 horizontal)and the produced crude oil, natural gas (including dissolve gas), condensate oil are 247.2×104m3, 11×108m3 and 18.7×104m3 respectively.The oil recovery percent is 23.6%, field water cut is 61% and natural gas recovery is 8.3%.The yearly crude oil output is more than 50×104t, the yearly off-take rate is maintained above 7%.Looking back the 3 years' development road, we got a lot of success and as well as lessons and we hope our experience be helpful to the development of other field in the East China Sea.
