【摘要】：綜合利用地震、鉆井、巖心觀察等資料,精細(xì)落實(shí)烏石東區(qū)斷裂發(fā)育及沉積相展布特征,明確烏石東區(qū)斷裂與沉積關(guān)系,闡述斷裂組合控制砂體沉積的模式。研究結(jié)果表明,烏石東區(qū)流沙港組地層發(fā)育同向平行型和反向平行型斷裂組合,具體形態(tài)相應(yīng)分別為斷溝、斷槽、走向斜坡以及斷裂坡折。順斷裂走向,砂巖粒度變細(xì)、分選變好,靠近斷裂下降盤,砂體厚度大、粒度粗,斷裂對(duì)砂體展布具有明顯控制作用。斷裂對(duì)砂體沉積的控制作用表現(xiàn)為斷層活動(dòng)導(dǎo)致上升盤形成相對(duì)凸起,下降盤形成相對(duì)低地,砂體從凸起向低地匯聚。同時(shí),沿?cái)嗔炎呦?砂體優(yōu)先選擇斷層活動(dòng)性較弱的位置向低地聚集。
[Abstract]:Based on seismic, drilling and core observation data, the characteristics of fault development and sedimentary facies distribution in Wushi Eastern region are carefully carried out, the relationship between fault and sedimentation in Wushi Eastern region is clarified, and the mode of controlling sand body deposition by fault combination is expounded. The results show that the strata of the Liushagang formation in the eastern part of Wushi District are formed in parallel and reverse parallel fault assemblages, and the specific forms are fault trenches, fault troughs, strike slopes and break of fault slopes respectively. Along the fault strike, the grain size of sandstone becomes finer, the separation becomes better, the sand body thickness is large, the grain size is coarse, and the distribution of sand body is controlled obviously by faults. The controlling effect of fault on sand body deposition is that the movement of fault leads to the formation of relative bulge in the rising plate and the formation of relatively low area in the descending plate, and the sand body converges from the uplift to the low ground. At the same time, along the fault strike, the sand body preferentially chooses the location where the fault activity is weak and accumulates to the low ground.
