摘要

摘要: 北部湾盆地涠西地区于W4井渐新统涠洲组三段获高产工业油气流，实现了北部湾盆地新区油气勘探突破。通过对W4井古近系原油及相关钻井岩心样品实验测试结果的研究，结合区内勘探新资料与邻区原油测试成果，重点开展了油源对比与成藏主控因素分析。研究认为，涠西地区W4井涠洲组三段油气藏属于断块型油气藏，其原油来自于母质类型较好的流沙港组成熟烃源岩，油气成藏受控于断层侧向封堵与盖层条件2个关键因素。

Abstract: Recently, SINOPEC obtained high-yield industrial oil and gas flows in the third member of the Oligocene Weizhou Formation in well W4 in Weixi area of the Beibuwan Basin, and achieved a breakthrough in oil and gas exploration in the New Area of the Beibuwan Basin. An oil-source correlation was made and the major factors control-ling oil and gas accumulation were studied based on the test results of crude oil and related drill core samples from well W4 in the Paleogene, combined with new exploration data from the study area and crude oil test results from the adjacent areas. The third member of Weizhou Formation in well W4 is a fault block type oil and gas reservoir, and the crude oil of which came from the mature hydrocarbon source rock of the Liushagang Formation. Hydrocarbon accumulation was controlled by two key factors including the lateral sealing characteristics of faults and cap rock conditions.
