文章在总结了四川盆地采气工程科技攻关和实际应用效果的基础上，对目前国内外采气工程技术发展现状从完井工艺技术、压裂酸化技术、排水采气工艺技术、修井工艺技术等四方面进行了调研，重点分析了四川盆地天然气上产对采气工程技术的需求及存在的主要技术难点，这表现在石炭系气藏稳产难度大、飞仙关组气藏开采难度大，还有异常高压气藏、多产层气藏、致密砂岩低渗透气藏的开采风险和增产难度等，提出了采气工程技术下步发展方向和重点攻关技术以及要达到的预期目标。

CURRENT STATUS AND DEVELOPING DIRECTION OF GAS RECOVERY TECHNIQUES IN SICHUAN BASIN (1) 1)

The fruits to overcome the technical difficulties and put into operation are summed for the gas recovery engineer in Sichuan Basin. The current developing status of gas recovery techniques at home and abroad is investigated including the follow 4 aspects: Well completion techniques, Fracturing and acidizing techniques, Techniques of gas recovery by water drainage and Well rehabilitation techniques. To increase gas production in Sichuan basin, the requirements to the gas recovery techniques are explained and the main technical problems are analyzed. The problems include that it is difficult for carboniferous gas reservoirs to stabilize production and for the gas reservoirs of Feixiaguan group to exploit, and the exploiting risk and production-increasing difficulty for the gas reservoirs with abnormal high pressure, the gas reservoirs with multiple pays, and the tight sand gas reservoirs with low permeability. Also, it is proposed the developing direction, the key technical problems to solve and the expected targets of gas recovery techniques in future.
