鲁克沁稠油油藏位于吐哈盆地吐鲁番坳陷的中部,是目前在该盆地三叠系中发现的惟一稠油油藏,也是该盆地中规模较大的石油聚集区,具有复杂而独特的聚集规律。印支末期的构造运动使该构造带在印支末期前后的地势发生了显著变化。这种构造上的复杂变化与某些成藏条件的变化造成了鲁克沁稠油聚集带异常的稠油聚集特点。该稠油聚集带东高西低,说明稠油的运移曾出现过较大规模的自东向西的运聚。高孔隙度厚层砂岩中的断层能形成侧向封堵,并形成厚层断块稠油油藏。稠油聚集带不同部位储层的含油饱和度与孔隙度的关系存在较大差异,石油的注入位置不在现今构造带的最低部位,而在其倾斜构造带中东部的玉东1井区。
The Luqqin heavy oil reservoir is located in the middle of Turpan Depression in the Turpan-Hami basin and is the only heavy oil reservoir currently found in the Triassic of this basin. It is also a large oil accumulation area in the basin with complex and unique The law of aggregation. The tectonic movement in the end of Indosinian period made the tectonic belt change significantly before and after the end of Indosinian. This structurally complex change and some changes in hydrocarbon accumulation conditions result in the accumulation of heavy oil in the heavy oil accumulation zone of the Ruqqin heavy oil. The heavy oil accumulation zone is high in the east and low in the west, indicating that heavy oil migration has occurred in a relatively large scale from east to west. Faults in high-porosity thick-bedded sandstones can form lateral sealing and form thick-bedded fault heavy oil reservoirs. The relationship between oil saturation and porosity in different parts of heavy oil accumulation zone is quite different. The petroleum injection location is not in the lowest part of the present tectonic zone, but in the Yudong 1 well in the eastern part of the tilted tectonic belt.
