解釋
碎屑相-
The sediments are detrital and largely of greywacke facies.
沉積巖為碎屑質，大部分屬于雜質砂巖相。 -
On the basis of the types of sand stone, light and heavy mineral associations, planimetric map of sedimentary facies and directions of palaeoflow, it is considered that detrital material of terrigenous deposit of chang6 - 8 oil - beds in this area come from southwest provenance, northeast provenance, west provenance and south provenance, respectively, which are the denudation area of huating - longxian county in southwestern, yinshan ancient land in the northern, the denudation area of yantong mountain and tongxin to the west of yangjiajuzi - yinjiacheng county and qinling ancient land in the southern
根據砂巖類型、輕、重礦物組合、沉積相帶平面展布及古水流方向等特徵的分析，認為研究區延長組長6 ? 8油層組陸源碎屑物質來自西南、東北、西部和南部四大物源區，分別為西南華亭?隴縣一帶剝蝕區，北部陰山古陸，西部的楊家咀子、殷家城以西的煙筒山、同心地區剝蝕區和南部秦嶺古陸。 -
The north provenance provided main detrital material, which can be delicately divided into two different sections, taipusiqi, ji ' ning area in the east and zha ' ertai mountain, wula mountain in the middle of yinshan ancient land. the distribution of gas pool in the eastern part of ordos area was obviously controlled by sedimentary facies belts
北物源區提供了主要的碎屑物質，它又可細分為東、西兩個不同的部分，分別為陰山古陸東部太僕寺旗、集寧地區和陰山中部的渣爾泰山、烏拉山地區。 -
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。
