| description | Based on the exploration and development achievements of the Sulige Gasfield in the Ordos Basin, tight sandstone gas yield has been increased essentially in China. Recovery enhancement is always the core subject in researches. In this paper, the development history of the Sulige Gasfield was reviewed focusing on the technological progress in single well production enhancement. Then, the technical ideas on and countermeasures for transforming the traditional development modes and increasing recovery factor were discussed. It is shown that the development technologies in the evaluation and the production enhancement and stabilization of giant tight sandstone gas reservoirs are changed progressively. The fast increase of gas production in this field is made possible by well location arrangement technology based on sweep spot screening, horizontal well development technology, well type and well pattern optimization technology, fast drilling technology, reservoir stimulation technology, drainage gas recovery technology and integrated construction mode. And finally, the technical ideas of recovery enhancement during the 13th Five-Year Plan were proposed in nine aspects, including gas field development, planning and evaluation technology based on single-well life cycle analysis; dynamic evaluation and infilling technology for mixed well patterns targeting recovery enhancement; one-shot recovery enhancement technology for a new areal pattern area with integrated multiple well patterns and multiple series of strata; reserve evaluation model based on risk and benefit evaluation; gas-well precise management technology with multi-dimensional matrix; potential tapping technology for low production and low efficiency wells; novel wellsite environmental protection technology; surface process based on integrated equipments; and C3+ mixed hydrocarbon recovery technology. It provides technically reliable support for the development of tight sandstone gas reservoirs in the Sulige Gasfield during the 13th Five-Year Plan. |
