摘要
新场气田是四川盆地西部坳陷中段一典型远源多类型、多层系的低渗透致密陆相碎屑岩气藏叠置而成，并具备优越立体压裂开发条件的大型气田。自1995年12月投入立体压裂开发以来，先后压裂168井次，累积加砂177m3，累积增加天然气产能702×104/d，增产水平16倍，日增输气180×104m3/d，已累积增输气量8．34×108m3，已创造经济效益5亿元，增加储量271．18×108m3，并形成了一套以三维精细气藏描述为基础，立体开发方案为原则、蓬莱镇组低渗透致密气藏压裂技术为核心技术、沙溪庙组超致密气藏整体压裂技术为关键技术的立体压裂开发模式。
Xinchang gas field is a multi-type multi-layer combination of typical distal continental low Permeability tight elastic reservoirs in the middle of the west Sichuan depression. It is a large-scale gas field with conditions available for stereo fracturing development. Since the gas field was put into stereofracturing development in December 1995, fracturing activities have been 135 times, accumulative sand used is 1270m3, accumul tive production increased is 605×104m3/d, they increase productivity by a factor of 11. 5 in average, increased gas transmission rate is 150×104m3/d, accumulative gas transmission increase is 2.2×108m3 and total economic benefit has reached 400 million RMB. Meanwhile, according to applications of stereofracturing, stereo fracturing development model is formed.
