【摘要】：通過采用巖心觀察、薄片鑒定、掃描電鏡觀察、壓汞實驗等技術(shù)手段,利用儲層特征定性描述與成巖改造孔隙量定量表征相結(jié)合的研究方法,對紅層儲層沉積成巖特征和儲集空間成因類型進行研究,明確紅層儲層物性的主控因素。結(jié)果表明:紅層沉積時期發(fā)育沖積扇—洪水-漫湖—鹽湖沉積體系;儲層主要發(fā)育在沖積扇、漫湖坪、漫湖席狀砂、漫湖灘壩中,儲層中主要發(fā)育原生粒間孔、殘余粒間孔、粒間溶孔、粒內(nèi)溶孔等4類孔隙;紅層儲層受控于沉積作用和成巖作用,其中沉積作用表現(xiàn)為巖石粒徑和成熟度對儲層孔隙結(jié)構(gòu)和物性的影響,而成巖作用對儲層物性起到明顯的控制作用,壓實減孔量主要受控于深度和填隙物含量控制,膠結(jié)減孔量受控于早期堿性成巖環(huán)境的強弱,溶蝕增孔量受控于中晚期酸性成巖環(huán)境的強弱,離湖盆中心越近,膠結(jié)減孔量、溶蝕增孔量越高,反之則越低。
[Abstract]:By means of core observation, thin section identification, scanning electron microscope, mercury injection experiment technique, the reservoir characteristics of qualitative and quantitative research methods to characterize rock pore volume transformation combination, the red layer reservoir sedimentary characteristics and reservoir space types are studied, the main control reservoir clear red factor of reservoir property. The results show that the alluvial fan and flood Lake - Saline Lake sedimentary system of red sedimentary period; the main reservoirs in the alluvial fan, over Lake Ping, over Lake sand sheet, diffuse lake dam, the reservoir mainly developed primary intergranular pores, residual intergranular pores. Intergranular dissolution pores, intragranular dissolved pores and other 4 types of pore; red reservoir controlled by sedimentation and diagenesis, the sedimentary rock is the size and maturity of reservoir pore structure and physical properties of the influence of diagenesis to control effect on Reservoir since the reduction of hole compaction The amount is controlled by the depth and filler content control, cement porosity reduction is controlled by the early alkaline diagenetic environment is weak, increasing of pore volume is controlled by dissolution in late acidic diagenetic environment is weak, from the center of the basin near the cement porosity reduction, dissolution pore increasing Liangyue high, and vice versa.
