杭州湾地区第四系超浅层气的开发及营销

THE DEVELOPMENT AND MANAGEMENT OF QUATERNARY EXTRASHALLOW GAS RESERVOIRS IN HANGZHOU BAY,

杭州湾地区第四系超浅层气藏具有埋深浅、压力低、气藏分散、单位面积储量低的特点，对该类气藏，过去由于技术和认识所限，往往认为无明显的商业性开采价值。随着对浅层气勘探开发重要性的深入认识和具体实践，使商业性开发该类气藏成为了现实；提出了一套切实可行的勘探、开发、集输工艺技术及营销策略；围绕经济效益这个目标，在降低成本、简化工艺措施及流程、采用经济实用和方便的营销政策等方面作了大量的尝试与工作，其认识为合理开发及应用浅层油气资源开拓了新的思路，具有一定的参考价值。

The Quaternary extrashallow gas reservoirs in Hangzhou Bay are of the characteristics of shallow burial depth,low pressure,dispersion and low per unit area reserves.Aimed at the characteristics,a set of feasible exploration,development and gathering transfering techniques as well as management tactics such as reducing cost,simplifying technological process ctc.is proposed out.
