【摘要】：大安油田位于松遼盆地的中央坳陷區(qū)大安—紅崗階地,J南區(qū)塊位于大安油田的西南部,靠近背斜構(gòu)造軸部,屬于構(gòu)造—巖性油藏。區(qū)塊內(nèi)發(fā)育兩條主斷層和一條次生小斷層,斷層走向為北北西向,由于小斷層切割影響,導(dǎo)致小斷層與西邊主斷層條帶區(qū)域井網(wǎng)不規(guī)則。前人的研究主要是針對整個大安油田,很少對J南區(qū)塊進(jìn)行精細(xì)的研究,但是因為受到構(gòu)造、巖性等的影響,各區(qū)塊間的沉積微相有很大差異,而且因為沉積體系的特殊性,前人對此爭議不斷。因此對本區(qū)地層進(jìn)行精細(xì)劃分、沉積微相進(jìn)行精細(xì)研究都是極為重要的,能夠?qū)τ蜌饪碧脚c開發(fā)進(jìn)行有效的指導(dǎo)。本論文以測井?dāng)?shù)據(jù)為主體資料,測井曲線常規(guī)識別為基礎(chǔ),綜合運用最大熵譜分析,將大安J南區(qū)塊泉四段分為4個中期旋回和1個長期旋回,建立了大安油田J南區(qū)塊層序地層劃分方案。研究區(qū)泉四段劃分為4個油組14個地質(zhì)小層,最終建立了研究區(qū)泉四段的高分辨率層序地層格架。通過繪制大安油田與J南區(qū)塊的泥巖顏色指數(shù)平面圖、ZTR指數(shù)平面圖、砂厚與砂地比平面圖,并結(jié)合松遼南部盆地的單井相分析、巖心照片和區(qū)域沉積背景綜合分析認(rèn)為研究區(qū)泉四段物源來自西部白城水系和西南部�？邓�。泥巖顏色主要為棕紅色或紫紅色,部分地區(qū)為灰綠色、灰色。后者主要分布在泉四段上部,反映出一個水進(jìn)的沉積過程,表明泉四段的上部沉積物主要處于氧化環(huán)境。砂巖類型主要為長石巖屑砂巖,其中長石及巖屑成分含量較高,穩(wěn)定成分含量較少;碎屑顆粒磨圓度較差,分選性好,呈點狀接觸,基質(zhì)含量高,結(jié)構(gòu)成熟度低,說明離物源較近或者受改造作用較小。分析認(rèn)為研究區(qū)泉四段發(fā)育末端扇沉積體系,其最大的特征為:砂體中富含泥質(zhì)條帶,河道的沖刷面之上常直接發(fā)育平行層理。通過對各小層砂體和微相的分析,繪制了大安油田J南區(qū)塊泉四段各小層砂體厚度平面圖、沉積微相平面圖以及沉積微相剖面圖,最終建立了研究區(qū)末端扇沉積體系的沉積模式,明確了砂體的分布特征和時空演化規(guī)律。
[Abstract]:The Da'an oilfield is located in the central depression of Songliao Basin, the Da'an-Honggang terrace is located in the southwestern part of the Da'an oilfield, near the anticline structural axis, and belongs to the tectonic-lithologic reservoir. There are two main faults and one minor secondary fault in the block. The strike of the fault is NNW. Due to the influence of the small fault cutting, the well pattern of the small fault and the west main fault strip is irregular. Previous studies have mainly focused on the entire Da'an Oilfield, and few detailed studies have been carried out on the South J block. However, due to the influence of structure and lithology, the sedimentary microfacies of each block are very different, and because of the particularity of the sedimentary system, There was a lot of controversy about it from previous generations. Therefore, it is very important to divide the strata and study the sedimentary microfacies in this area, which can guide the exploration and development of oil and gas effectively. On the basis of logging data and conventional recognition of logging curves, this paper synthetically uses maximum entropy spectrum analysis to divide the fourth member of Quan in the south block of Da'an J into four intermediate cycles and one long-term cycle. The sequence stratigraphic division scheme of South J block in Da'an Oilfield is established. The fourth member of Quan formation in the study area is divided into 4 oil formations and 14 geological layers. Finally, the high-resolution sequence stratigraphic framework of the fourth member of the study area is established. By drawing the mudstone color index plan and the sand thickness and sand soil ratio plan of Da'an Oilfield and Southern J Block, and combining with the analysis of single well facies in the southern Songliao Basin, The comprehensive analysis of core photographs and regional sedimentary background shows that the source of the fourth member of Quan in the study area comes from the Baicheng water system in the west and the Baokang water system in the southwest. Mudstone color is mainly brownish red or purplish red, some areas are grayish green, gray. The latter mainly distributes in the upper part of the fourth member of the spring, which reflects the deposition process of a water advance, indicating that the upper sediment of the fourth member of the spring is mainly in the oxidation environment. The sandstone type is mainly feldspathic lithic sandstone, in which feldspar and lithic components are high, and stable components are less, and clastic grains are of poor roundness, good sorting, point contact, high matrix content and low structural maturity. It shows that the material source is near or the effect of modification is less. It is considered that the terminal fan sedimentary system developed in the fourth member of the Quan formation in the study area is characterized by the following characteristics: the sand body is rich in muddy bands and the parallel bedding is often developed directly above the erosion surface of the river course. Based on the analysis of the sand bodies and microfacies of each small layer, the thickness plans, sedimentary microfacies and sedimentary microfacies profiles of each small sand body in the fourth member of Quan formation in the South J block of Da'an Oilfield are drawn. Finally, the sedimentary model of the end-fan sedimentary system in the study area is established, and the distribution characteristics and space-time evolution law of the sand body are clarified.
