【摘要】：古龍油田位于黑龍江省大慶市大同區(qū),隨油田勘探程度增加,以往對本區(qū)的地震解釋精度已不能滿足油田實際生產(chǎn)的需要,有必要對本區(qū)四個地震工區(qū)(巴彥查干、他拉哈、常家圍子、龍南)進行高精度的層位及斷層解釋,另本區(qū)油水關(guān)系復(fù)雜,控制因素較多,迫切需要研究構(gòu)造、微幅度、斷層的幾何學(xué)、運動學(xué)特征以及斷層側(cè)向封閉性對油水分布的影響,來分析總結(jié)油水分布的主控因素。以層序地層學(xué)、構(gòu)造地質(zhì)學(xué)為指導(dǎo),利用地震數(shù)據(jù)并結(jié)合鉆井、測井、試油、巖心等數(shù)據(jù),以地震資料和測井資料的有機結(jié)合為前提,采用大比例尺顯示,逐線解釋方法解釋層位,采用多種相干體結(jié)合以及三維可視化技術(shù)來識別厘定斷層并繪制葡萄花油層頂面深度構(gòu)造圖,采用趨勢面法識別與手動識別相結(jié)合的方法識別微幅度構(gòu)造,統(tǒng)計了斷層的幾何學(xué)特征、運動學(xué)特征,采用斷層泥比率(SGR)來定量評價葡萄花油層頂面斷層的側(cè)向封閉性,得出以下認識,目的層頂面整體呈現(xiàn)“一鞍兩凹三隆”的構(gòu)造形態(tài),共識別圈閉47個,微幅度構(gòu)造80個;斷裂密集帶對河道砂體的走向和延伸范圍起到控制作用,地壘、地塹、順向斷階以及反向斷階均可能成為油氣有利富集區(qū),斷裂主要在早白堊紀時期、青山口組沉積時期、姚家組-嫩一二段沉積時期三個時期活動;本區(qū)斷層側(cè)向封閉性多為好和中等,封閉性差的斷層多集中在西斜坡處,封閉性好的斷層對油氣起到很好地遮擋作用,分析了微幅、斷層組合、期次、密集帶以及斷層封閉性對油水分布的影響并給出優(yōu)選井位3口。
[Abstract]:Gulong oilfield is located in Datong District in Heilongjiang city of Daqing Province, with oil exploration in this area to increase the degree of previous seismic interpretation accuracy can not meet the actual needs of oil production, it is necessary for the four earthquake area in this region (Bayan Chagan, targan, Changjiaweizi, Longnan) horizon and fault interpretation in high the accuracy of the other oil-water relationship is complex, the control of many factors, it is urgent to study the structure, micro amplitude, fault geometry, influence on the distribution of oil and water and the closed kinematic characteristics of lateral fault, to analyze and summarize the main control of oil-water distribution factors. Based on the sequence stratigraphy, structural geology as a guide, using seismic data and in combination with drilling, logging, oil testing, core data, with the combination of seismic data and well logging data is the premise of the large scale display, by line interpretation method using coherent interpretation horizon, combination and 3D As a technology to identify and determine fault drawing of Putaohua reservoir in the depth of the top structure map, the identification method of trend surface identification and manual identification method of combining micro amplitude structure, statistical geometric characteristics, fault kinematics, the fault gouge ratio (SGR) to the lateral quantitative evaluation of Putaohua reservoir in the top surface of fault sealing of the following understanding, to the top of the overall presentation of "structural shape of a saddle, a total of two concave samlung" identify 47 traps, micro amplitude structure 80; fault zones to the channel sand body and extends to the control function, Horst, graben, consequent fault order and reverse fault order may be the favorable oil and gas enrichment zone, the fracture was mainly in the early Cretaceous period, during sedimentary period of Qingshankou formation, three sedimentary period of Yaojia period of one or two tender activities; for good and moderate lateral sealing of the fault, poor sealing ability Most of the faults are located at the west slope. The well sealed faults play a good role in shielding the oil and gas. The influence of micro amplitude, fault combination, stage, dense zone and fault sealing on the distribution of oil and water is analyzed, and 3 wells are selected.
