【摘要】：莫10區(qū)塊位于莫索灣凸起南部斜坡帶處,四而環(huán)生油凹陷,油氣資源豐富、構(gòu)造位置有利、成藏條件優(yōu)越,是油氣運(yùn)移的有利指向區(qū)域。其三工河組二段油氣成臧復(fù)雜,巖性橫向變化快,含油砂層邊界的刻畫(huà)是勘探成功的關(guān)鍵因素之一。 本論文以莫10區(qū)塊三維地震資料為基礎(chǔ),通過(guò)地震地質(zhì)層位精細(xì)標(biāo)定,建立起侏羅系井震地層格架,對(duì)目的層三工河組進(jìn)行了精細(xì)構(gòu)造解釋。工區(qū)整體構(gòu)造為山東南向西北抬升的單斜,地層起伏變化趨勢(shì)較緩,層問(wèn)厚度變化均勻,重新確立了大量斷層的分布,落實(shí)了研究區(qū)基本構(gòu)造形態(tài),工區(qū)東南部發(fā)育大型鼻狀構(gòu)造帶,該鼻狀構(gòu)造被NE-SW和NW-SE向兩組斷裂切割,使該鼻狀構(gòu)造被分割成多個(gè)斷塊圈閉。新發(fā)現(xiàn)構(gòu)造圈閉6個(gè),總面積33km2,并對(duì)各個(gè)圈閉進(jìn)行了精細(xì)的圈閉構(gòu)造描述。在鉆測(cè)井資料統(tǒng)計(jì)分析的基礎(chǔ)上,分析了井下儲(chǔ)層測(cè)井響應(yīng)特征,通過(guò)測(cè)井約束反演,地震屬性提取對(duì)目的層進(jìn)行了儲(chǔ)層預(yù)測(cè)與含油氣檢測(cè),其中利用曲線重構(gòu)的方法提高了儲(chǔ)層預(yù)測(cè)的精度。針對(duì)該區(qū)地震資料分辨率低、砂體尖滅線難以落實(shí)的問(wèn)題,利用正演技術(shù)、頻譜分解技術(shù)對(duì)主力含油砂體尖滅線進(jìn)行精細(xì)刻畫(huà)。結(jié)合沉積相等地質(zhì)資料,根據(jù)構(gòu)造形態(tài),儲(chǔ)層預(yù)測(cè),屬性分析、砂體尖滅線范圍,預(yù)測(cè)了含油砂體分布范圍。最終明確了有利勘探區(qū)域,提出了評(píng)價(jià)井部署方案,為莫10區(qū)塊下一步評(píng)價(jià)與開(kāi)發(fā)方案部署奠定了基礎(chǔ)。
[Abstract]:Block Mo 10 is located in the southern slope zone of Mosuowan uplift, which is characterized by abundant oil and gas resources, favorable structural location and favorable reservoir forming conditions, and is a favorable direction for oil and gas migration in the second member of the Sangonghe formation, where the formation of oil and gas is complex, and the formation of oil and gas in the second member of the Sangonghe formation is complicated. The lithology changes quickly and the boundary of oil-bearing sand layer is one of the key factors of successful exploration. Based on the 3D seismic data of Mo10 block, the seismic stratigraphic framework of Jurassic well is established by fine calibration of seismic geological horizon. The fine structural interpretation of Sangonghe formation is carried out. The whole structure of the work area is a monoclinal uplift from the south to the northwest of Shandong Province. The variation trend of stratigraphic fluctuation is relatively slow, and the thickness of the strata changes uniformly, so the distribution of a large number of faults has been re-established. The basic structural morphology of the study area has been carried out. In the southeast of the study area, a large rhinoid structural zone has been developed. The nose structure has been cut by two groups of faults, NE-SW and NW-SE, and the nose structure has been divided into several fault block traps. Six new structural traps have been discovered. The total area is 33km2, and the trap structure is described in detail. Based on the statistical analysis of drilling logging data, the logging response characteristics of downhole reservoir are analyzed, and the logging constraint inversion is carried out. Reservoir prediction and oil and gas detection are carried out by seismic attribute extraction, in which the precision of reservoir prediction is improved by curve reconstruction. In view of the low resolution of seismic data in this area, it is difficult to carry out the sand body tip out line. Using forward modeling technique and spectrum decomposition technique to depict the main oil-bearing sand body pinchout line. Combined with sedimentary equivalent geological data, according to structural shape, reservoir prediction, attribute analysis, range of sand body tip out line, The distribution range of oil-bearing sand bodies is predicted. Finally, the favorable exploration area is determined, and the evaluation well deployment scheme is put forward, which lays a foundation for the next evaluation and development plan deployment in Mo 10 Block.
