中国浅层油气藏的特征及其资源潜力分析

Characteristics of shallow petroleum accumulations in China and analysis of their petroleum resource potential

中国多年来对浅层地区未进行有效的勘探开发和给予应有的重视。对渤海湾盆地等主要大中型盆地浅层油气藏的类型、分布特征和地质特征等的分析表明,中国浅层油气在地质上总体具有埋藏浅、成因复杂、受构造-岩性等复合性影响显著、储量规模与丰度大小不一、油藏类型多且分布广、资源量分布不均等特征,在勘探和开发上具有易勘探、成本低和易出砂出水、稳产难度大等优点和不足。指出中国浅层油气的潜力区域在东部,对浅层油气资源潜力进行了分析,认为浅层油气资源潜力很大,要重视浅层油气资源的勘探开发,重视新理论、新技术、新方法等在浅层隐蔽油气藏勘探开发过程中的应用。

For many years China has not carried out effective exploration and development of shallow petroleum nor paid due attention to it. Analysis of the types, distribution characteristics and geological factors of shallow petroleum accumulations in China＇s major large and medium-sized basins such as the Bohai Bay basin indicates that in terms of geology China＇s shallow petroleum is generally characterized by shallow burial, complex origin, remarkable influence by combined structural and lithological factors, difference in reserves and abundances, multiple types of petroleum accumulations and their wide distribution. and uneven distribution of resources and that in terms of exploration and development China＇s shallow petroleum has such advantages and disadvantages as easy exploration, low costs, easy sand and water flow and difficulty in keeping stable production. The authors also point out that eastern China is China＇s main region with shallow petroleum potential. Analysis of shallow petroleum resource potential suggests that shallow petroleum resources have a vast potential, so we should pay attention to exploration and development of shallow petroleum resources and to applications of new theories, new techniques and new methods in exploration and development of shallow hidden petroleum accumulations.
