基于分子结构的热稳定性以及氢键形成机理,烷基二苯并噻吩类参数4-/1-MDBT,2,4-/1,4-DMDBT和4,6-/1,4-DMDBT,兼具备表征有机质成熟度以及油气运移的属性,可以作为示踪油藏充注方向与途径的有效分子参数.这些参数在珠江口盆地新近系砂岩孔隙型油藏与塔里木盆地塔河油田奥陶系碳酸盐岩岩溶缝洞网络型油藏两种例证中首次试用,均取得良好效果.烷基二苯并噻吩类示踪参数具有较为广泛的应用范畴,可应用于不同成熟度的原油,特别是较为缺乏有效分子参数的高成熟~过成熟原油,也可应用于遭受过强烈生物降解作用的原油,甚至于同源石油两期充注的混合油,但对于混源油油藏则要慎重使用.
Based on the thermal stability of the molecular structure and the hydrogen bond formation mechanism, the alkyl dibenzothiophenes parameters 4- / 1-MDBT, 2,4- / 1,4-DMDBT and 4,6- / 1,4-DMDBT, It also can be used as an effective molecular parameter for tracing the direction and route of reservoir filling by the characteristics of organic matter maturity and hydrocarbon migration.These parameters can be used as effective molecular parameters in the Neogene sandstone pore reservoir of Pearl River Mouth Basin and Ordovician of Tahe Oilfield in Tarim Basin The first trial of two kinds of illustrations in the carbonate rock karst cave network reservoir have achieved good results.The alkyldibenzothiophenes tracer parameters have a wide range of applications and can be applied to different maturity of crude oil, In particular, the mature and over-mature crude oil, which lacks effective molecular parameters, can also be applied to the crude oil that has undergone strong biodegradation, or even the mixed oil filled in two phases of the same source petroleum, but for the mixed-source oil reservoir, Use carefully.
