6. The reservoir lithology of oil bearing Huagang formation on Sudi structural belt in Xihu depression is mainly lithic arkose, feldspathic litharenite and feldspathic quartzitic sandstone.
7. Among all sequence strata of exploration target, it mainly developed medium-coarse clastic arkose in high water system, which overlies and underlies the primary sequence interface as well.
8. Analysis results of a number of testing data indicated that: sandstone reservoir of Fu-Yang oil-bearing layer has lower composition maturity, mainly are feldspathic arenite and lithic arkose.
9. Analysis results of a number of testing data indicated that: sandstone reservoir of Fu-Yang oil-bearing layer has lower composition maturity, mainly are feldspathic arenite and lithic arkose.
The Eogene reservoir is mainly composed of arkose, the Mesozoic reservoir is mainly composed of lithic arkose. 中生界储集层主要为岩屑质长石砂岩。
The main types of clastic sandstones are feldspathic litharenite and lithic arkose in the Cretaceous of the Songliao basin. 松辽盆地白垩系砂岩以长石岩屑砂岩和岩屑长石砂岩为特征。
