近年来,在盐定地区的长8、长9中发现了多个工业油流井,已发现多个含油富集区,勘探前景广阔。本文在前人研究成果的基础上,结合研究区基础资料,分析了沉积地层、储层以及烃源岩、油气运移聚集特征等成藏地质条件,研究了盐定地区长8油层组油气富集规律和成藏控制因素,认为长8油藏通过长7优质烃源岩生烃增压为排烃提供动力,通过裂缝以及渗砂体运移成藏,其分布具有具＂近源、低压、优相＂规律;明确了建产有利区带,为进一步扩大盐定地区长8以及相关层中的低渗油层后续评价和部署开发提供地质理论支撑。
近年來,在鹽定地區的長8、長9中髮現瞭多箇工業油流井,已髮現多箇含油富集區,勘探前景廣闊。本文在前人研究成果的基礎上,結閤研究區基礎資料,分析瞭沉積地層、儲層以及烴源巖、油氣運移聚集特徵等成藏地質條件,研究瞭鹽定地區長8油層組油氣富集規律和成藏控製因素,認為長8油藏通過長7優質烴源巖生烴增壓為排烴提供動力,通過裂縫以及滲砂體運移成藏,其分佈具有具＂近源、低壓、優相＂規律;明確瞭建產有利區帶,為進一步擴大鹽定地區長8以及相關層中的低滲油層後續評價和部署開髮提供地質理論支撐。

In recent years,the long salt given area 8,9,found in a number of long industrial oil wells,oil-rich region has been found that a number of exploration prospects.In this paper,based on the results of previous studies,combined with basic data for the study area, analysis of the sedimentary strata,reservoir and source rocks,hydrocarbon migration and accumulation characteristics of reservoir geological conditions of the salt given area rich oil and gas Chang 8 Set of rules controlling factors and accumulation,that the long length of 7, 8 reservoir quality through the hydrocarbon source rock to power booster for the expulsion, through the cracks and seepage migration and accumulation of sand,and its distribution has a ＂near-source,low pressure,excellent phase ＂law;clear favorable zone build capacity for further expansion of salt given area Long 8 layers of low permeability and related follow-up evaluation and deployment of reservoir development to provide support for geological theory.
