【摘要】：儲(chǔ)層細(xì)分對(duì)比存在的問(wèn)題主要表現(xiàn)為兩個(gè)方面:一是儲(chǔ)層細(xì)分對(duì)比的結(jié)果往往是巖性單元,多不具等時(shí)性;二是儲(chǔ)層細(xì)分對(duì)比的結(jié)果仍不夠精細(xì),不能滿足高含水階段剩余油挖潛的需要。其根本原因是對(duì)層、地層結(jié)構(gòu)認(rèn)識(shí)的局限性。儲(chǔ)層細(xì)分對(duì)比以傳統(tǒng)地層學(xué)理論為指導(dǎo),認(rèn)為層、地層結(jié)構(gòu)符合"層狀"模式,即地層是全區(qū)分布、近于水平、相互平行的,并且層與層水平疊置。然而,層序地層學(xué)等突破了傳統(tǒng)地層學(xué)對(duì)層、地層結(jié)構(gòu)的認(rèn)識(shí),認(rèn)為地層不一定全區(qū)分布、不一定水平、不一定相互平行;層的空間位置變化大,相互間可呈超覆、退覆等疊置特點(diǎn)。構(gòu)型要素分析法更細(xì)致地揭示了儲(chǔ)層結(jié)構(gòu)特征,認(rèn)為原來(lái)劃分的層是復(fù)合體,需進(jìn)一步細(xì)分。通過(guò)層次界面劃分,復(fù)合體可以被細(xì)分成一系列形態(tài)各異、分布復(fù)雜的構(gòu)型單元。從問(wèn)題根源入手提出相應(yīng)對(duì)策,解決儲(chǔ)層細(xì)分對(duì)比存在的問(wèn)題需要以沉積學(xué)、層序地層學(xué)、地震地層學(xué)等理論為指導(dǎo),運(yùn)用構(gòu)型要素分析法進(jìn)行層次界面劃分。
[Abstract]:The main problems of reservoir subdivision and correlation are two aspects: one is that the result of reservoir subdivision and correlation is often lithologic unit, and the other is that the result of reservoir subdivision and correlation is not precise enough, It can not meet the need of tapping the potential of remaining oil in high water cut stage. The fundamental reason is the limitation of understanding the formation and stratigraphic structure. The subdivision and correlation of reservoir is guided by the traditional stratigraphic theory. It is considered that the formation and stratigraphic structure conform to the "stratiform" model, that is, the strata are distributed in the whole area, are close to the level, parallel to each other, and the layers and layers are stacked horizontally. However, sequence stratigraphy breaks through the traditional stratigraphic understanding of stratigraphic structure, and holds that stratigraphy is not necessarily distributed in the whole area, not necessarily horizontal, and not necessarily parallel to each other. The characteristics of overlay etc. The structural characteristics of the reservoir are revealed in more detail by the method of structural element analysis, and it is considered that the layers originally divided are complex bodies, which need to be further subdivided. By hierarchical interface division, the complex can be subdivided into a series of complex configuration units with different shapes and distributions. In order to solve the problem of reservoir subdivision and correlation, it is necessary to use the theory of sedimentology, sequence stratigraphy and seismic stratigraphy to divide the stratigraphic interface with the method of structural elements analysis under the guidance of the theory of sedimentology, sequence stratigraphy and seismic stratigraphy.
