吐哈油田三塘湖火成岩储层岩性复杂、物性很差,需要对储层进行大型压裂改造才能获得具有经济价值的油气产能.研究利用套管完井前后XMAC测井采集得到的全波波形数据,采用STC技术处理得到地层波的波形、幅度、能量和地层的备向异性情况,进而定性分析人工裂缝,计算出油气层压裂裂缝的高度和方向,该技术方法在实际施工中得到了较好的应用.

The lithology of igneous reservoirs in Santanghu Area of Tuha Basin was complex and its physical property was poor, large hydraulic fracture was needed to obtain an economical productivity. ± On the basis of the full-waveform data collected by XMAC logging before and after well completion, waveform, magnitude and energy of the formation wave and the anisotropy of the formation were obtained by using STC technique, thus the artificial fracture was qualitatively analyzed and its height and direction in hydrocarbon zone were calculated. This method is well used in actual operation.
