| 摘 要： | 通过对柯柯亚下侏罗统气藏、储层特征分析,认为J1b气藏受构造控制,带油环;有利储集相带为辫状河三角洲前缘水下分流河道和河口坝砂体,在有效含气范围内,富集高产与溶蚀粒内孔、粒间孔的发育程度密切相关,裂缝对改善储层渗流条件起到积极作用。受高阻煤层封挡条件的限制,能有效封挡气柱高度最大在180m左右。针对致密砂岩气层识别难,提出看井径、重声波、轻电阻率的三要素法。

| Abstract: | Through the analysis of gas reservoir and reservoir characteristics of the Lower Jurassic in Kekeya area,it is thought that J1b gas reservoir with oil ring is controlled by structures,and favorable reservoir facies belts are braided delta front underwater distributary channel and mouth bar sandbody.Within the effective gas range,enrichment hydrocarbon is closely related to the development degree of intragranular dissolved pore and intercrystalline pore.The fractures have played a positive role in improving ... |
