摘要
巴喀致密气藏具有低孔、低渗、地应力高且变化大、天然裂缝发育程度不均匀等特点。射孔后无自然产能或自然产能很低。针对气藏的特征及压裂的难点,开展了有针对性的压裂工艺技术研究和现场试验,单井日增产量明显提高,压裂改造取得了一定的效果。
The tight-gas-sandstone reservoir is characterized by low porosity, low permeability, high stress with obvious variation and uneven developed natural fracture in Baka. After perforation, there is no natural productivity or very low natural productivity in the reservoir. Aiming at the characteristics of the gas reservoir and fracturing difficulties, the study of fracturing technology and field experiment are conducted. Success rate of the fracturing is high, and daily production of single well increased, fracturing stimulation has taken effect.
