【摘要】：楊武寨構(gòu)造帶位于冀中凹陷饒陽凹陷南部,該區(qū)構(gòu)造復(fù)雜,具有進(jìn)一步勘探評(píng)價(jià)研究的必要。本論文研究了楊武寨構(gòu)造帶構(gòu)造演化及斷裂體系特征。論文針對(duì)老油田目前構(gòu)造研究存在的問題,充分利用已有資料,在前人研究的基礎(chǔ)之上,主要通過全區(qū)重點(diǎn)井地層對(duì)比、精細(xì)三維地震解釋、分析構(gòu)造演化史,對(duì)斷裂體系進(jìn)行了研究,進(jìn)一步理順了斷裂組合,總結(jié)出構(gòu)造特征,為指導(dǎo)油田開發(fā)提供了基礎(chǔ)。完成研究區(qū)內(nèi)重點(diǎn)井地層劃分對(duì)比,確定區(qū)域內(nèi)兩套一級(jí)標(biāo)志層(Es1下底W型低阻泥巖段和Es3頂部的特殊巖性段),兩個(gè)二級(jí)標(biāo)志層(Es2頂“細(xì)脖子”泥巖段和Es3上高阻基值夾刺刀狀的塊狀高阻特殊巖性段)及多個(gè)輔助標(biāo)志層。通過多工區(qū)地震資料拼接,使用多工區(qū)地震資料分析研究區(qū)的區(qū)域構(gòu)造背景和構(gòu)造關(guān)系,分析構(gòu)造形成機(jī)理:本研究區(qū)位于饒陽凹陷東南部,處于構(gòu)造轉(zhuǎn)換帶,受周邊三個(gè)不同應(yīng)力方向的凸起所影響。東部的獻(xiàn)縣凸起地層北抬南降;西部的高陽深澤低凸起地層南抬北降;南部的新河凸起地層?xùn)|抬西降;獻(xiàn)縣、高陽深澤兩大凸起塊體的拆離運(yùn)動(dòng)是饒南凹陷大型拆離滑覆構(gòu)造形成的基本因素,本研究區(qū)屬饒南凹陷大型拆離滑覆構(gòu)造的南部;區(qū)內(nèi)古近系、新近系的不同構(gòu)造形跡是兩大塊體在第三紀(jì)時(shí)期拆離過程中的不同構(gòu)造活動(dòng)的產(chǎn)物。結(jié)合構(gòu)造形成機(jī)理及斷裂力學(xué)研究,使用多種地震屬性對(duì)全區(qū)進(jìn)行了精細(xì)三維地震解釋,研究區(qū)內(nèi)主要斷層為獻(xiàn)縣斷層、孫虎—楊武寨斷層、留楚—皇甫村斷層,剖面上主要發(fā)育“y”字型、“馬尾狀”、斷階型斷層組合。平面上楊武寨地區(qū)東西向分異明顯,可劃分為三個(gè)構(gòu)造區(qū)帶,即楊武寨西部單斜帶(北抬南傾),楊武寨中央背斜和楊武寨東洼槽東陡帶。南北向又可劃分為三個(gè)局部構(gòu)造區(qū):楊武寨主體背斜區(qū)、楊武寨北斷鼻構(gòu)造區(qū)、楊武寨南斷鼻構(gòu)造區(qū)。從斷層活動(dòng)的時(shí)序性分析,孫虎—楊武寨構(gòu)造帶的斷裂發(fā)育具有多期性,共有三個(gè)期次的斷裂發(fā)育。斷層的發(fā)育期次與該區(qū)的構(gòu)造運(yùn)動(dòng)密切相關(guān)。北部的楊武寨北斷鼻構(gòu)造區(qū)即為三期構(gòu)造疊置區(qū),斷裂發(fā)育,構(gòu)造破碎,為油氣有利聚集區(qū)。
[Abstract]:Yangwuzhai structural belt is located in the south of Raoyang Sag, Jizhong Sag. The structural evolution and fault system characteristics of Yangwuzhai tectonic belt are studied in this paper. Aiming at the problems existing in the current structural research of the old oil fields, the paper makes full use of the existing data and, on the basis of previous studies, mainly analyzes the history of structural evolution by means of stratigraphic correlation of key wells in the whole area, fine three-dimensional seismic interpretation, and analysis of structural evolution history. The fault system is studied, the fault assemblage is further straightened out, and the structural characteristics are summed up, which provides the basis for guiding oil field development. Complete the stratigraphic division and correlation of key wells in the study area, Two sets of first-grade marker layers (the W-type low-resistivity mudstone segment at the bottom of Es1 and the special lithologic section at the top of Es3), two second-order marker layers (the "fine neck" mudstone section of Es2 and the bayonet shape of high resistivity base value on Es3) are determined. Segment) and multiple auxiliary marking layers. Based on the combination of seismic data in multi-work area, the authors analyze the regional tectonic background and tectonic relationship of the study area by using seismic data of multi-work area, and analyze the formation mechanism of the structure: the study area is located in the southeast of Raoyang sag, and is located in the structural transition zone. Affected by three different stress directions around the bulge. Xianxian uplift strata in the east carry south down; Gaoyang Shenze low uplift strata in the west lift north to the north; Xinhe uplift strata in the south lift west to the east; Xien County, The detachment movement of the two major uplift blocks in Shenze, Gaoyang, is the basic factor for the formation of large-scale detachment and slip structures in the Raonan Sag. The study area belongs to the southern part of the large-scale detachment and slip structure in the Raonan Sag and the Paleogene system in the area. The different tectonic traces of the Neogene are the product of different tectonic activities in the process of separation of the two blocks during the Tertiary period. Combined with the study of structural formation mechanism and fracture mechanics, the fine 3D seismic interpretation of the whole area is carried out by using various seismic attributes. The main faults in the study area are Xianxian fault, Sunhu-Yangwuzhai fault, Liuchu-Huangfu fault. There are mainly y-shaped, equine-shaped and faulted fault assemblages in the section. The east-west differentiation of Yangwuzhai area is obvious on the plane, which can be divided into three structural zones, namely, the western Yangwuzhai monocline (north to south tilting), the Yangwuzhai central anticline and the eastern steep belt of Yangwuzhai Dongwa trough. The south-north direction can be divided into three local tectonic areas: the main anticline in Yangwuzhai, the north fault nose structure in Yangwuzhai, and the south fault nose in Yangwuzhai. The fault development of Sunhu-Yangwuzhai tectonic belt is multi-period, and there are three stages of fault development. The development times of faults are closely related to the tectonic movement in this area. The north Yangwuzhai North faulted nose structure area is the third stage structure superposition area, the fault develops, the structure is broken, it is the favorable oil and gas accumulation area.
