摘要
应用地温地压系统的原理 ,详细地分析了准噶尔盆地东部地区地温、地压及温压系统在纵向和平面上的分布特征。在纵向上建立了北部低压型复式温压系统、中部单一型温压系统和南部高压型复式温压系统 3种模式 ;在平面上建立了 9种温压系统分区。同时 ,结合该地区油气藏的分布特征 ,探讨了温压系统在纵向和平面上对油气运聚及成藏的控制及影响因素 ,发现油气主要聚集在相对低能的温压系统平面分区内。根据温压系统与油气运聚成藏的关系建立起
The geotemperature and formation pressure data of more than 300 explorated wells in the east of Junggar basin were collected. The characteristics of geotemperature\|formation pressure ( θ\|p ) systems are analyzed. In vertical, there are three types of θ\|p systems: composite θ\|p system of overpressure type in the south belt, simple θ\|p system in the middle belt, and composite θ\|p system of low\|pressure type in the north belt. Oil and gas are mainly accumulated in relative low energy circumstance, such as normal\|temperature\|normal\|pressure or high\|temperature\|normal\|pressure environments, etc. With the analysis of the characteristics of petroleum accumulation in this area, four types of models of pool formation are established, namely the mono\|period model of pool formation in Huoshaoshan, the two\|period separation model of pool formation in Cainan, the mono\|period model of pool formation in Shanan, and the multi\|period composite model of pool formation in the south belt.
