【摘要】：大湾气田是近年来我国发现的地质条件极为复杂的典型高含硫气田之一,其储层埋藏深、厚度薄、平面变化大、储量丰度低、硫化氢含量高、裂缝-孔隙发育,国内外尚无成功开发先例。为了安全、经济、高效开发以大湾气田为代表的复杂高含硫气田,形成了复杂高含硫气田水平井整体开发新技术。其中包含4项核心技术:一是双重介质高含硫气田储层精细描述技术,二是双重介质高含硫气田开发技术政策优化技术,三是高含硫气田水平井开发完井技术,四是高含硫气田水平井分段酸压技术。应用这些核心技术,成功建成了世界上第1个水平井整体开发的大湾复杂高含硫气田,并已推广到国内类似气田,取得了良好的经济效益和社会效益。
[Abstract]:Dawan gas field is one of the typical high sulfur gas fields discovered in China in recent years. Its reservoir is deep buried, thin in thickness, large in plane change, low in reserves, high in hydrogen sulfide content, and well developed in fractures and pores. There is no precedent for successful development at home and abroad. For the sake of safety, economy and high efficiency, the complex high sulfur gas field represented by Dawan gas field has been developed, and a new technology for the whole development of horizontal well in complex high sulfur gas field has been formed. It includes four core technologies: one is the fine reservoir description technology of dual medium high sulfur gas field, the other is the development policy optimization technology of dual medium high sulfur gas field, and the third is horizontal well development and completion technology of high sulfur gas field. Fourth, acid fracturing technology for horizontal wells in high sulfur gas fields. The application of these core technologies has successfully built the world's first integrated development of the Dawan complex high sulfur gas field with horizontal wells, and has been extended to similar gas fields in China, with good economic and social benefits.
