【摘要】：准噶尔盆地东部火山岩岩体相互叠置、彼此交错、识别难度大,对有效储层预测和油气开发带来极大困难。在"一体一藏"油藏模式的指导下,利用地质、岩心、测井、分析化验、地震和开发动态等多种资料,明确了准噶尔盆地东部裂隙式火山喷发模式和火山喷发期次,在此基础上,根据岩性旋回和地震反射特征划分出6个火山岩岩体和12个岩性段,结合试油结果进一步确定了研究区具有2个主力火山岩储层岩体,其中的单个火山岩储层岩体具有面积广、厚度与规模均较大的特征;火山岩岩体整体向东南方向倾斜,在断裂控制下与上覆沉积地层构成"屋脊"状的断层-地层圈闭油藏。此次研究可为后续的火山岩岩体储层预测和提高油气产能提供指导。
[Abstract]:Volcanic rock bodies in the eastern Junggar basin overlap with each other and are difficult to identify, which brings great difficulties to effective reservoir prediction and oil and gas development. Under the guidance of the "one body and one reservoir" reservoir model, using geological, core, logging, analysis, seismic and development data, the fissure volcanic eruption model and volcanic eruption period in the eastern part of Junggar Basin have been determined. On this basis, according to the lithologic cycle and seismic reflection characteristics, 6 volcanic rock bodies and 12 lithologic sections are divided. Combined with the oil test results, it is further determined that there are 2 main volcanic rock reservoirs in the study area. The single volcanic rock reservoir is characterized by wide area, large thickness and large scale, and the volcanic rock mass inclines to the southeast, and the fault-stratigraphic trap reservoir is formed with the overlying sedimentary strata under the control of faults. This study can provide guidance for the prediction of volcanic rock mass reservoir and the improvement of oil and gas productivity.
