【摘要】：隨著勘探開發(fā)的深入,對四川盆地磨溪龍王廟組氣藏流體分布的認識發(fā)生變化,由早期的無水氣藏或無邊底水氣藏轉變?yōu)榇嬖谶叺姿�、局部封存�?表現(xiàn)出復雜的氣水關系,這制約了氣藏的高效開發(fā)。為此,本次研究綜合現(xiàn)有錄井、巖心、測井、地震、測試及生產資料,識別出溶蝕孔洞發(fā)育區(qū),在此基礎上,采用印模法恢復研究區(qū)龍王廟組古地貌格局,結合現(xiàn)今構造特征,綜合分析認為:(1)油氣分布既受現(xiàn)今構造圈閉控制,又受有利巖相控制,也受古地貌影響;(2)古地貌控制了早期油氣聚集,在地勢較高的緩坡區(qū)聚集油氣,在局部洼陷區(qū)滯留地層水,在地勢變陡的低部位形成富水區(qū);(3)在現(xiàn)今構造圈閉范圍內,由于物性、閉合度和海拔高差存在差異,導致東、西部井區(qū)含氣性不同,西區(qū)富氣程度優(yōu)于東區(qū);(4)結合古今構造格局,在古地貌地勢低部位(地勢低于-300m)、現(xiàn)今構造低部位(海拔低于-4385m)廣泛分布邊水;(5)當古地貌地勢低于-300m時,在現(xiàn)今構造和古地貌相對凸起部位存在局部油氣聚集。
[Abstract]:With the development of exploration and development, the understanding of fluid distribution in the gas reservoir of the Longwangmiao formation in Moxi, Sichuan Basin has changed from the early anhydrous gas reservoir or the boundless bottom water gas reservoir to the existing edge bottom water reservoir, which shows a complex gas-water relationship. This restricts the high efficiency development of gas reservoir. Therefore, this study synthesizes the existing logging, core, logging, seismic, testing and production materials, and identifies the developed area of dissolved holes. On this basis, the paleogeomorphological pattern of Longwangmiao formation in the study area is restored by imprinting method, combining with the present structural characteristics. The comprehensive analysis shows that the oil and gas distribution is controlled not only by the present tectonic traps, but also by the favorable lithofacies and the paleogeomorphology) the early oil and gas accumulation was controlled by paleogeomorphology, and oil and gas were accumulated in the gentle slope areas with high topography. In the area of present tectonic traps, due to the differences in physical properties, closure and elevation, the gas-bearing properties in the eastern and western well areas are different, due to the formation water retention in the local sag areas and the formation of water-rich areas in the lower parts of the steepening terrain. The natural gas abundance in the western region is better than that in the eastern region, combining with the paleogeomorphological pattern. When the paleogeomorphic topography is lower than -300mg (topography is lower than -300mg), the lower part of the structure (altitude is lower than -4385m) is widely distributed, when the paleogeomorphology topography is lower than -300m, Local oil and gas accumulation exists in the relative uplift of present structure and paleogeomorphology.
