Directed by new theories and approaches of sedimentology , diagenesis and reservoir evaluation , focused on marine clastic reservoir of donghe sandstone member , in tarim basin , strata and depositional system of donghe sandstone member are classified ; typical depositional facies types , depositional model and horizontal distribution have been studied through depositional facies analysis of 17 single wells , combined with seismic data . major diagenetic events , stages and " four history " collaboration have been systematically analysesed , furthermore , the relation between reservoir diagenesis and porosity evolution has been built ; thorough studies on reservoir lithology , physical property and pore structure , reservoir development related to depositional envoironment , diagenesis and tectonic has been discussed ; reservoir has been evaluated and predicted by five influential parameters drawn from the results of the study on depositional facies , diagenesis and reservoir characteristic . in the end , favourable reservoir body distribution has been pointed out 本論文以沉積學(xué)、沉積巖石學(xué)、沉積成巖作用與儲層地質(zhì)學(xué)、儲層評價技術(shù)的新理論新方法為指導(dǎo),以塔里木盆地巴楚組東河砂巖段海相碎屑巖儲層為主要研究對象,通過17口典型井的單井地層沉積相分析和成巖作用分析,結(jié)合地震資料,對東河砂巖段地層和沉積體系進行了詳細(xì)劃分,研究了東河砂巖段分布區(qū)的典型沉積相類型、沉積模式及其平面展布特征;系統(tǒng)分析了東河砂巖段碎屑巖儲層的主要成巖事件、成巖期次及其四史配置關(guān)系,指出了儲層成巖與孔隙演化的關(guān)系;深入研究了東河砂巖段碎屑巖儲層的巖石學(xué)特征、物性分布、孔隙結(jié)構(gòu)等特征,著重討論研究了沉積環(huán)境、成巖作用和構(gòu)造作用對儲層發(fā)育的影響;運用“權(quán)重”評價法結(jié)合地層沉積相、成巖演化和儲層特征研究的結(jié)果,選取了五個對儲層發(fā)育有重要影響的參數(shù)對儲層進行了整體的評價和預(yù)測,指出了塔里木盆地東河砂巖段儲層有利儲集體的分布狀況。
