近数十年来的调查表明,在含油气区的基岩地层中常能遇见裂缝及空穴发育带,在其中可以积聚具有工业规模的碳氢化合物。在基岩中到处可以发现含油气的显示──裂缝壁上的石油被膜、钻井液中的石油泡沫、石油类气体的析出等。在世界各地已发现数十个基岩油气田,其中最大的德聂泊尔-顿(?)茨盆地、曼格什拉克、东南亚、委内瑞拉、利比亚及美国的一些基岩油气田。 越南南部大陆架可以认为是最有价值并研究得最深入的具有基岩烃类矿床的地区之一。此处已开发了几个油气田,其中之一是白虎油田。它是由俄罗斯-越南合资企业“越俄石油公司”开采的。其勘探与开发的成果资料已在国际地质大会上作过报告,并在越文与英文的期刊上发表过(Areshev E.G.等.,1991;) Shnip O.A.等,1992)。有些关于白虎油田的资料已于另一论文(A.H.Дмитризвскии等,1992)中作了介绍,并在国立古布金石油天然气学院的学术大会上宣读过(Aриоив ЕГ等,1994)。 在大地构造图上,越南南部大陆架是印度支那─巽他陆间过渡区的一部分。该大陆架包 In recent decades, surveys have shown that fractures and hole development zones can often be found in bedrock formations in oil and gas-bearing areas where industrial-scale hydrocarbons can accumulate. Oil and gas can be found everywhere in the bedrock - the oil envelope on the wall of the crack, the oil bubbles in the drilling fluid, and the precipitation of petroleum gases. Dozens of bedrock oil and gas fields have been discovered around the world, including some of the largest bedrock fields in the Dnipropetrovsk Basin, Mangalshrac, Southeast Asia, Venezuela, Libya and the United States. The southern Vietnamese continental shelf can be considered as one of the most valuable and well-studied areas with bedrock hydrocarbon deposits. Several oil and gas fields have been developed here, one of which is the Baihu Oilfield. It is mined by the Vietnam-Vietnam joint venture “Vietnam Oil Corporation.” Outcomes of its exploration and development have been reported at the International Geological Congress and published in both Vietnamese and English journals (Areshev E.G. et al., 1991; Shnip O.A. et al., 1992). Some of the information on the Baihu oilfield was presented in a separate paper (A.H.Дмитризвскии et al., 1992) and was presented at an academic conference at the National College of Petroleum and Natural Gas (Aриоив ЕГ et al., 1994). On the tectonic map of the Earth, the southern Vietnamese continental shelf is part of the Indo-Pacific transition zone. The continental shelf package
