摘要
针对冷家堡油田洼70块薄层稠油油藏因油层薄、直井试采出砂严重造成储量无法动用这一难题,通过水平井注汽开发可行性论证及试验,对该块利用水平井整体部署开发,取得了良好效果。形成一套以水平井开发薄层油藏的油藏评价技术、储层预测技术、井身轨迹控制技术、完井技术、生产参数优化技术等先进配套技术,在相似油藏开发中具有借鉴和指导意义。
Wa 70 heavy oil reservoir in Lengjiapu oilfield is hard to produce because of thin oil reservoir and serious sanding problem during pilot production by vertical wells. The feasibility of steam flooding with horizontal wells has been studied and tested. Horizontal wells are placed over the entire reservoir and have achieved satisfactory effect. A complete set of techniques of developing thin oil reservoir with horizontal wells has been formed,including reservoir evaluation,reservoir prediction,wellbore trajectory control,well completion,production parameters optimization,etc.,which are meaningful to the development of analogous reservoirs.
