摘要
北部湾盆地涠西南凹陷涠洲A油田流沙港组三段油气资源规模较大,但存在有效储层为薄互层、断块破碎和经济可行性差等问题。针对油藏开发现状,综合运用类比法、产能公式法、改进的谢尔卡乔夫公式法和水驱控制程度法来确定井网类型和井网密度,综合研究储层展布、储层物性和可类比断块油田,确定井距;对比分析天然能量开发、注水开发和注气吞吐开发方式,优选最佳开发方式。
Reservoirs in the 3rd member of Liushagang Formation of Weizhou A Oilfield,Weixinan sag,Beibu Gulf basin are characterized by thin interbed,small fault block area and poor economic feasibility,though there are large scale of oil and gas resources.The well pattern and well density were determined by analogy method,formula of production capacity,modified Shercachev formula method and the water flooding control degree method,according to the present situation of reservoir development.The well spacing was confirmed via a comprehensive study of reservoir distribution,reservoir physical properties and developed fault block oil field analogy.The development mode was decided by comprehensive analysis and comparison of natural energy development,water injection and gas injection and puff to determine the way energy is added.
