准噶尔盆地永进油田的主力油层为侏罗系西山窑组，埋藏深约6000 m，储层物性具特低孔、特低渗的特点。油井试油试采结果表明，储层物性是制约永进油田西山窑组油层富集高产的主控因素。通过大量测井资料、砂岩薄片、铸体薄片、扫描电镜等资料的分析认为，深埋作用、胶结作用、、异常高压、泥质含量及溶蚀作用是导致永进油田西山窑组储层特低孔、特低渗的根本原因，据储层演化历程模拟出西山窑组储层孔隙的演变模式。
準噶爾盆地永進油田的主力油層為侏囉繫西山窯組，埋藏深約6000 m，儲層物性具特低孔、特低滲的特點。油井試油試採結果錶明，儲層物性是製約永進油田西山窯組油層富集高產的主控因素。通過大量測井資料、砂巖薄片、鑄體薄片、掃描電鏡等資料的分析認為，深埋作用、膠結作用、、異常高壓、泥質含量及溶蝕作用是導緻永進油田西山窯組儲層特低孔、特低滲的根本原因，據儲層縯化歷程模擬齣西山窯組儲層孔隙的縯變模式。

The major reservoir of Jurassic in Yongjin oilfield buried depth about 6000 meters, in the junggar basin.The reservoir physical property has the characteristics of low porosity,low permeability.The results of well testing show that the reservoir property is restricted in the high yield and the main control factors of reservoir enrichment from the field. Through a lot of logging data, sandstone thin section, casting thin sections and scanning electron microscopy analysis, deep effect,cementation,and abnormal high pressure,shale content and dissolution is cause the reservoir from the yongjin oilfield has low porosity, low permeability of the root causes,and according to the reservoir evolution finally simulate the xishanyao group of reservoir pore evolution mode.
