利用测井资料评价暂堵转向工艺在苏里格气田的应用效果

Application Effect Evaluation of Temporary Plugging and Fracturing Technology in Sulige Gas Field by Logging Data

苏里格气田纵向上存在多套砂体储层及厚层砂体储层,为了减少压裂次数、降低压裂成本,同时不降低压裂改造效果,后期改造过程中应用了大量的暂堵转向压裂工艺。通过压裂后在套管内进行交叉偶极子阵列声波测井来评价压裂缝缝高及流体渗流能力,以及通过生产测井来定量计算储层改造后的产出,可以有效评价暂堵转向压裂技术在油气储层段的改造效果。

There are many sets of sand body reservoirs and thick sand body reservoirs in the vertical direction of Sulige gas field. In order not to reduce the effect of fracturing while reducing the number and the cost of fracturing, temporary plugging and fracturing technology was applied in the later reconstruction process. Cross dipole array acoustic logging was used to evaluate the fracture height, the fluid percolation ability, and production logging was used to quantitatively calculate the output after reservoir reconstruction, which can effectively evaluate the effect of temporary plugging and fracturing technology in oil and gas reservoir.
