摘　　要：苏里格气田苏75区块气井普遍储层较薄,部分井储层隔层厚薄不均,所有储层均已全部射开,完全改造困难。针对该类井的地质特征及井况,研究并开发出一种分层压裂补充工艺,即"投球+封隔器"复合压裂工艺,用以解决储层隔层厚薄不均,难以彻底改造的难题。经苏里格气田苏75区块共应用两口井,工艺成功,效果显著,提高了气井的采收率。Most of gas wells in Su-75 block of Sulige gas field have thin reservoir and uneven thickness. All of the production reservoirs have been completely perforated, but are difficult to be reformed. According to the geological characteristics of the well and well conditions, we developed a layered fracturing added technology, that is pitch and packers composite fracturing techniques, to solve the problems such as reservoir layer's uneven thickness and reform difficulty. The application of two wells in Su-75 block of Sulige gas field gained good results and improved the recovery of a gas wells.
