Embodiment Construction
[0056] Below in conjunction with accompanying drawing, the present invention is described in further detail:
[0057] The invention relates to a composite acid fracturing construction pipe string and an application method thereof, which are suitable for staged construction operations of various well types such as clastic rock vertical wells, horizontal wells, open holes and cased wells. The present invention realizes the segmenting of different acid fracturing methods such as large-scale acid fracturing, fixed-point jet perforation, jet fracturing, etc. in one trip of construction pipe strings for long open-hole well sections through the optimization configuration of the construction pipe string structure and the improvement of the application method. Improve the effect of stratified and segmented reconstruction of clastic rocks in Tahe Oilfield, increase the swept volume and complexity of fractures in clastic rock reservoirs, reduce construction costs, and improve the effect o...
