摘要
2002年10月彩南油田C125井在侏罗系石树沟群获得高产油气流,标志着准噶尔盆地东部地区该层系滚动勘探开发取得了历史性突破。石树沟群油藏在剖面上的跨度为360m,储集层为薄互层砂体,横向变化快,油气层电阻率较低,是典型的低阻油藏,滚动勘探开发难度较大。通过对成藏机理分析,建立了彩南油田石树沟群成藏模式,认为断裂是油气运移的主要通道,大断裂对油藏的控制作用明显,断裂和砂体的搭配关系是油藏成藏的必要条件。
In October, 2002, high-yielding oil-gas flow gushed in C125 Well at Jurassic Shishugou group started historical breakthrough in rolling exploration and development of this group in Jundong (eatern Junggar basin) area. Shishugou group is a typical low-resistance reservoir with section span of 360 m, thin interbedded sands and great lateral variation, which brings the difficulty for rolling exploration and development. Therefore, further recognition and research of its petroleum accumulation mechanism are of great importance in the next step prospecting. In terms of structure, sedimentary setting and petroleum accumulation, this paper analyzes the reservoir-controlled factors as guide for the next step work.
