The basins in west china were downfaulted depression basins in jurassic and cretaceous, and foreland basins in cenozoic. these basins formed not only marine facies source rocks ( oil type ) and reservoirs but also continental facies source rocks ( coal type and oil type ) and reservoirs
因此，中國類前陸盆地基本石油地質條件與國外富油氣前陸盆地相比，除海相烴源巖的質量不及後者外，其它方面並無明顯不足，且具有發育陸相烴源巖和儲集巖的優勢。 -
2 ) analyses and researches systematicly the lithofacies, sedimentary facies and depositional environment of the dayi conglomerate in the cenozoic longmenshan foreland basin. this paper analyzes detailed six coarse elastics lithofacies, five mid - elastics lithofacies and three fine elastics lithofacies. establishes the association of three depositional environment types including alluvial fan and river
2 ）對新生代龍門山前陸盆地大邑礫巖巖相、沉積相和沉積環境進行了系統分析和研究，劃分出6種粗碎屑巖相、 5種中碎屑巖相、 3種細碎屑巖相，確定了大邑礫巖為沖積扇相、河流相沉積環境的組合。 -
Under the guidance of new principles and methods of modern sedimentology, detrital petrography, reservoir geology, diagenesis, this thesis has carried out detailed study on paleogene formation correlation, sedimentary environment, characteristics of sedimentary facies and diagenesis of the eastern kuche depression, tarim basin, dina area being taken as the main target of the study. based on the core, geology logging, log and seismic data from 9 typical wells, combined with the data of the adjoining area, the dominant sedimentary types of the study area have been recognized and illustrated, such as fan - delta, lacus and normal delta. in terms of the analysis on the sedimentary facies of typical and connecting wells in different areas and facies belt, together with the paleogene tectonic evolution characteristics of foreland basin, the distribution and evolution of the sedimentary facies of the study area have been clearly discovered both vertically and laterally
通過對該區9口井的巖芯、錄井、測井、地震資料及鄰區資料的分析，識別並闡述了庫車坳陷東部下第三系的幾種主要的沉積相類型，如扇三角洲相、湖泊相和正常三角洲相；通過對不同地區、不同相帶典型井及連井的沉積相分析，結合前陸盆地在下第三系的構造演化特點，弄清了迪那地區下第三系沉積相的縱橫相發育展布和演化規律，並建立了沉積相模式；同時，初步開展了成巖作用、儲層孔隙演化和儲層發育模式的研究工作，科學合理地解釋了現今迪那地區下第三系儲產層主要發育在粉砂巖中的特殊現象，首次建立了下第三系儲層的發育演化模式，為庫車坳陷東部地區進一步尋找下第三系大儲量、高產油氣藏和有利的勘探區塊提供科學的、可靠的和最直接的地質依據。
