摘要
在理论研究和广泛调研的基础上，确定了多缝压裂的技术思路，通过层内形成多裂缝来进一步提高油层横向动用程度，扩大泄油面积，从而达到大幅提高产量的目的。在物模实验的启发下．创造性提出了定向射孔＋多缝压裂的新型技术，该技术通过定向射孔诱导迫使初始裂缝转向，最终形成相互独立的多缝。现场应用70口井，井均日增油0．6t，A井区试验井投产初期井均日增油1．2t，实践证明通过多缝压裂提高泄油面积可以达到增产的目的。
on the basis of the theoretical study and extensive research to determine the ideas of multi-seam frac- turing technology to further improve the reservoir horizontal producing extent, expansion of the oil spill area by the formation of multi-cracks within the layer, so as to achieve a substantial increase in the production.Inspired by the physical model experiments, creative oriented perforating ＋ multi-seam fracturing of the new technology, the technology oriented perforating initial cracks induced by forcing the turn, and ultimately the formation of in- dependent multi-seam.Field applications 70 wells,wells are increasing oil 0.6t A well test wells in the initial production wells are increasing oil 1.2t Practice has proved to improve the oil spill area can be achieved to in- crease production through a multi-seam fracturing.
