摘　　要：BYY2井对Eq4^(下)盐间8个韵律层进行分层压裂,合层试油,获少量油流。利用原油和盐间烃源岩色谱、质谱资料,并结合地质和工程资料进行分析和判断,综合研究认为:Eq4^(下)盐间各韵律层烃源岩由于沉积时环境存在差异;烃源岩存在三种类型;BYY2井的出油层为Eq4^(下)-15韵律。The less volume of oil was obtained by the layering fracturing and oil testing of sum layers in the 8 inter-salt rhythmic layers of the EQ4 lower in Well BYY2.Based on the data of crude oil and inter-salt source rock chromatography and mass spectrometry,combined with geological and engineering data,it is concluded that there are differences in the sedimentary environment of hydrocarbon source rocks in the inter-salt rhythmic layers of the EQ4 lower.There are three types of hydrocarbon source rocks;the oil layers in Well BYY2 is the EQ4 lower-15 cyclothem.
