【摘要】：對(duì)準(zhǔn)噶爾盆地車(chē)排子凸起新近系沙灣組已發(fā)現(xiàn)油藏從層位、規(guī)模、油性、物性、物源、類(lèi)型等方面進(jìn)行了梳理和總結(jié)。沙灣組共發(fā)育巖性、斷層-巖性、斷鼻三類(lèi)圈閉,儲(chǔ)層特征與油藏規(guī)模存在差異,油性分布較復(fù)雜。在明確沙灣組復(fù)雜油藏特征的基礎(chǔ)上,結(jié)合典型油藏解剖,認(rèn)為長(zhǎng)期繼承性的古隆起、高效的毯狀砂體輸導(dǎo)層、斷層縱橫向的封閉性、儲(chǔ)集層物性的差異、多源多期成藏過(guò)程及不同的保存條件是沙灣組油氣藏類(lèi)型多樣、油性復(fù)雜的主要控制因素。根據(jù)上述認(rèn)識(shí),預(yù)測(cè)毯狀砂體側(cè)向尖滅帶為有利的油氣聚集區(qū),從實(shí)鉆效果看,該區(qū)帶內(nèi)油氣顯示豐富,展現(xiàn)出較好的勘探前景。
[Abstract]:The reservoir has been found in the Shawan formation of the Neogene in Chepaizi uplift Junggar Basin in terms of horizon scale oil property physical property provenance and type.There are three types of traps in Shawan formation: lithology fault lithology and fault nose. The reservoir characteristics and reservoir size are different and the distribution of oil properties is complex.On the basis of defining the characteristics of complex reservoirs in Shawan formation, combined with the anatomy of typical reservoirs, it is considered that the long-term inherited paleouplift, the highly efficient carpetlike sand body transport layer, the sealing of faults in longitudinal and horizontal direction, and the difference of reservoir physical properties,The main controlling factors of the oil and gas reservoirs in Shawan formation are various types and complex oil properties in the process of multi-source and multi-period reservoir formation and different preservation conditions.According to the above understanding, it is predicted that the tapered belt of carpet sand body is a favorable oil and gas accumulation area. From the effect of drilling, the oil and gas in the zone is abundant and shows a good prospect for exploration.
