简介:气测参数图板法是储集层流体类型识别的一种重要方法,但在实际应用中往往由于油质的影响造成解释精度的下降。为了消除油质的影响,提高储集层流体解释的精度,通过对渤中M油田大量的录井、测井、测试、钻井及生产的数据归纳分析,提出反映储集层流体类型的3个气测烃指数——甲烷指数(COI)、全烃异常指数(TGI)及烃组分指数(DTI),然后依据不同油质分别建立了3个烃指数流体解释图板,可用以有效识别油层、气层及水层,提高了储集层流体的解释符合率。在该油田另外两口井中进行实际验证,平均解释符合率为88.5%,表明该图板的建立对渤中M油田后续的评价及开发工作具有重要意义。
简介:为利用科技进步提高生产效率,聚氨酯事业部于近期对聚醚60m^3生产线实施技术改造,生产效率提高20%,将增产聚醚18kt/a。由于该部聚醚装置不断扩建,生产规模不断扩大,对于聚醚中间品LP的配套生产形成了巨大压力。为与扩大后的规模相配套,提高LP生产效率、扩大聚醚产能,改造在60m^3生产线上增设外循环及循环冷却器,提高生产反应速度和原料的计量精度。改造后的60m^3生产线开车一次成功,生产周期从改造前平均每釜24h减少至19h,效率提高20%,且工艺稳定。改造后每年可增加LP产量3000t,从而增产聚醚10000t以上。
