|
摘要
为了加快三塘湖盆地石炭系火山岩勘探进程,促进储量升级动用,针对火山岩储层识别、油气水层评价困难及储层非均质性强,自然产能较低等技术难题,积极组织技术攻关。综合应用气测、定量荧光、气相色谱录井技术及ECS化学元素俘获测井、FMI成像测井技术,有效解决了火山岩综合评价难题。开展火山岩优质储层地震反射特征研究,准确描绘出优质储层分布范围。应用开展火山岩储层增产措施优化,研究出乳化压裂液体系,与强水敏的火山岩风化带储层有很好的配伍性,压裂增产效果良好。新技术的应用,有效地促进了石炭系勘探成果进一步扩大,两年石炭系卡拉岗组三级储层超过亿吨,形成了快速上产的优质储量区块。
To speed up the exploration of Carboniferous volcanics in the Santanghu Basin and to promote the use of reserves,technological research is conducted to solve the difficulties in volcanic reservoir identification and evaluation of oil/gas/water zones,and the problems of strong reservoir heterogeinity and low natural production.By applying the gas surveying technology,the fluorescence quantitative technology,the gas chromatography logging technology and the elemental capture spectroscopy(ECS) logging technology,the Formation Micro Image(FMI) well logging technology,the difficulties in volcanic reservoir evaluation are solved effectively.Seismic reflection characteristics of high-quality volcanic rock reservoirs are studied and the distribution range of high-quality reservoirs are delineated with high accuracy.Based on the optimization of stimulation technologies of volcanic reservoirs,the emulsion fracturing systems is worked out,and it shows good compatibility with the volcanic reservoir in weathered zone that has strong water sensitivity.The system demonstrates satisfying fracture-stimulation effect.The application of new technologies effectively promote Carboniferous exploration,production of the third-level reservoir of the Carboniferous Kalagang Formation exceeds 100 million tons within two years,and a block with high quality reserves is therefore formed.
