摘　　要：湘冷1井具有气层埋藏浅(400 m-500 m)、纵向上裂隙发育的特点,属低孔、低渗的含泥质灰岩致密储层。大量室内实验和研究采用“前置液酸压+闭合酸化”工艺技术,并优选了相应降阻酸和闭合酸配方。通过酸压实现了该井工业油气流的突破,取得了明显的增产效果,为新区海相浅层气的开发探索出了一套成熟的改造增产措施。Xianglengl well has features of being low buried layer of gas reservoir and growth of portrait cranny which belongs to low porosity and percolation of calcific compact rock with containing mud. By a good of lab experiments and studies, tech of preceding fluid for acid-ding and fracture and close acidding has been utilized and match prescription of corresponding dropping block acid and closing acid is optimized. The break out of producing gas and oil for this well by operation of acidding and fracture which reaches an obvious result of increasing production that explores a mature set of alteration and increasing production treatment for low layer natural gas in the new sea facies areas.
