摘要
位于准噶尔盆地腹部某构造凸起上的MD04井,在侏罗系三工河组中完试油获得"水层",试油结果与地质预期相差很大。通过对该井井筒条件、中完试油过程以及区域上的邻井对比分析认为,中完试油结果为"水层"是由于固井质量不合格导致下部水层上窜,而非目的层的真实反映。完井后对目的层进行完井试油获得工业油流,搞清了该井侏罗系三工河组储层的液性及产能。分析方法可为同类区域的试油试气提供借鉴。
In drillstem test of Sangonghe Group of Jurassic system,"acquifer" was found in well MD04 locating in some structural bulge in Junggar Basin.The testing result is greatly different from geological prediction.Based on the comparative analysis of borehole conditions,DST procedure and offset well in same zone,it is judged that "acquifer" results from moving up of lower water layer due to failed cement job quality.Upon well completion,the testing for oil discovered oil stream in bed of interest.As a result,liquidity and deliverability of reservoir in Sangonghe Group of Jurassic system was understood.
