【摘要】：長(zhǎng)春油田昌十區(qū)塊位于鹿鄉(xiāng)斷陷五星構(gòu)造帶的東北部,工區(qū)面積僅為0.5km2。雙陽(yáng)組二段是該區(qū)塊的主要產(chǎn)油層位。本文結(jié)合工區(qū)三維地震數(shù)據(jù)體、二次解釋及物性參數(shù)資料,以勘查地球物理學(xué)、沉積學(xué)、石油地質(zhì)學(xué)為理論支撐,運(yùn)用landmark和雙狐軟件開(kāi)展區(qū)塊內(nèi)部微幅構(gòu)造研究并分析油藏特征、成藏條件與剩余油的關(guān)系,再結(jié)合物性資料劃分流動(dòng)單元。最后運(yùn)用疊合分析的方法綜合考慮沉積微相、微幅構(gòu)造類型及流動(dòng)單元的劃分結(jié)果,預(yù)測(cè)了雙二段主力剩余油分布。具體內(nèi)容如下:一、微幅構(gòu)造的類型及分布利用landmark軟件完成工區(qū)內(nèi)部33口井的地震合成記錄,并在此基礎(chǔ)上識(shí)別地震反射標(biāo)志層及斷裂位置,制作砂組界面的構(gòu)造等值線圖。最終識(shí)別出雙二段的56個(gè)正向微幅構(gòu)造分布區(qū),其中正向微幅構(gòu)造包括微背斜、微鼻狀和微斷鼻3種。二、生儲(chǔ)蓋組合及成藏類型區(qū)內(nèi)以下生上儲(chǔ)為主,其油源主要來(lái)自雙一段。大量的烴源巖為形成油藏提供了基礎(chǔ),同時(shí)雙二段還發(fā)育了大量的河道砂體,該砂體物性較好可作為有利儲(chǔ)層。雙三段泥巖較厚且在全區(qū)均有分布,因此可形成穩(wěn)定的區(qū)域蓋層。區(qū)內(nèi)成藏類型較多,主要可劃分為構(gòu)造油藏、巖性-構(gòu)造油藏、巖性油藏三個(gè)大類,其中構(gòu)造油藏可劃分為背斜構(gòu)造油藏、斷鼻構(gòu)造油藏、鼻狀構(gòu)造油藏,巖性-構(gòu)造油藏主要為砂巖透鏡體-構(gòu)造油藏,巖性油藏可劃分為砂巖透鏡體油藏和砂體上傾尖滅油藏。三、流動(dòng)單元?jiǎng)澐旨笆Ｓ嘤头植純?yōu)選在前人小層對(duì)比以及物性分析的基礎(chǔ)上,計(jì)算工區(qū)內(nèi)36口井各成因砂體的物性參數(shù)并建立了滲流參數(shù)J的頻數(shù)-概率累計(jì)曲線,依據(jù)頻數(shù)-概率曲線分布圖上不同斜率的直線段將流動(dòng)單元?jiǎng)澐殖蒍≤500、500J≤1500、1500J≤4000、J4000四類,并以沉積相和斷點(diǎn)為界制作了流動(dòng)單元平面分布圖,再將流動(dòng)單元平面圖與微幅構(gòu)造相疊,最終優(yōu)選出了剩余油分布區(qū),該研究為制定挖潛措施提供了目標(biāo)。
[Abstract]:Changchun oilfield Chang ten block is located in Lu Xiang Wuxing structural fault depression in the northeast area, the area is only 0.5km2. two segment of Shuangyang Formation is the main oil producing formation in the block area. Based on 3D seismic data interpretation, two physical parameters, in exploration geophysics, sedimentary, petroleum geology theory use block, internal micro structure research and analysis of reservoir characteristics of landmark and DoubleFox software, relationship between the reservoir condition and residual oil, combined with the physical data flow unit division. Finally, by using the method of superposition analysis considering the sedimentary microfacies, micro structure type and division of the flow unit, double two the main section of the residual oil distribution forecast. The specific contents are as follows: first, the synthetic seismogram and the use of landmark software to complete the distribution area of 33 wells within the micro structure of the type, and on the basis of the recognition of seismic reflection The sign layer and fracture location, structural contour map making sand interface. Finally recognize double two section of the 56 positive micro structure distribution, the positive micro structure including micro and micro micro nosing anticline, fault nose 3. Two, source reservoir cap combination and reservoir types in the area below formation, the oil source mainly comes from the first member. A large number of source rock provides the basis for the formation of reservoir, and double two also developed a large number of channel sand body, the sand body with better properties can be used as reservoirs. Three double thick and mudstone in the region are distributed, so it can be the formation of a stable regional caprock. Area reservoir can be divided into many types, the main structural reservoir, lithologic structural reservoir, lithologic reservoir in three categories, which can be divided into structural reservoir anticline reservoir, fault nose structural reservoir, nose structure reservoir, lithologic structural reservoir is mainly sandstone lens body structural oil Reservoir, lithologic reservoir can be divided into sandstone lens reservoir and sandstone pinchout reservoirs. Three, division of flow units and remaining oil distribution optimization based on the analysis of the previous layer correlation and physical property parameters on the calculation in the work area of 36 wells in the sand and set up the frequency of seepage. The number of J probability cumulative curve, according to the frequency - probability distribution curve diagram of different slope of the straight line segment flow unit is divided into J = 500500J = 15001500J = 4000, J4000 four, and the sedimentary facies and the breakpoint boundary made flow unit distribution map, and then flow unit plane map and micro structure overlapping finally, selected the remaining oil distribution area, this study provides a target for the development of measures.
