垦东北坡垦东4以北地区是一有利的含油气地区,上第三系已有多口井获高产工业油气流,预测石油地质储量2000余万吨,已建产能20余万吨。垦东古2、垦东343已于下第三系见油气显示,展示了垦东地区第三系良好的勘探开发前景。本文综合分析垦东北坡浅海地区上、下第三系成藏控制因素。正确划分油藏类型,剖析典型油气藏基本特征、运聚成藏条件,揭示油气成藏机理,总结油气成藏规律和模式。
Kedongbei northeast of Kendong 4 is a favorable oil and gas area. There are many wells in the upper Tertiary which have high-yield industrial oil and gas flow. The predicted oil geological reserves are over 20 million tons and the built-up production capacity is more than 200,000 tons. Kendong 2 and Kendong 343 have been shown oil and gas in the Lower Tertiary to show the prospect of exploration and development of Tertiary in Kendong area. This paper comprehensively analyzes the controlling factors of the upper and lower Tertiary accumulation in the shallow sea area of northern Kenting, Kendong. Correctly classify reservoir types, analyze the basic characteristics of typical reservoirs, transport and accumulate reservoir forming conditions, reveal the mechanism of hydrocarbon accumulation, and summarize the rules and modes of hydrocarbon accumulation.
