【摘要】：在區(qū)域構(gòu)造作用方式和方向產(chǎn)生變化及復(fù)雜邊界條件的綜合影響下,分析復(fù)雜構(gòu)造變形及所形成構(gòu)造的特征及其油氣成藏.本文以黃金帶油田為例,利用新處理的高品質(zhì)三維地震資料,對(duì)本區(qū)構(gòu)造特征進(jìn)行精細(xì)刻畫,分析應(yīng)力場(chǎng)演化,并探討構(gòu)造對(duì)油氣成藏條件的控制作用.認(rèn)為本區(qū)沙三期存在北西-南東向的伸展構(gòu)造作用;東營(yíng)期為走滑構(gòu)造變形體制,最大主壓應(yīng)力方向?yàn)榻鼥|西向,表現(xiàn)為北東向右旋走滑、東西向擠壓和南北向伸展的構(gòu)造變形特征,同時(shí),二界溝斷層作為構(gòu)造帶邊界對(duì)局部應(yīng)力場(chǎng)的方向造成改變.研究結(jié)果表明:在復(fù)雜的應(yīng)力條件下,伸展構(gòu)造、走滑構(gòu)造、擠壓構(gòu)造、反轉(zhuǎn)構(gòu)造在本區(qū)均有發(fā)育,并存在特殊的構(gòu)造現(xiàn)象:斷層與褶皺樞紐的走向出現(xiàn)規(guī)律性漸變、走滑斷層平直段存在"海豚效應(yīng)"現(xiàn)象.結(jié)合區(qū)域應(yīng)力場(chǎng)的變化以及構(gòu)造帶邊界的影響,構(gòu)造變形疊加和復(fù)雜的先存構(gòu)造條件是產(chǎn)生復(fù)雜構(gòu)造現(xiàn)象的原因.構(gòu)造活動(dòng)與油氣成藏在時(shí)間上相契合,對(duì)油氣成藏與保存起到了至關(guān)重要的作用.
[Abstract]:Under the influence of the complex boundary conditions and the variation of regional tectonic action mode and direction, the characteristics of complex tectonic deformation and formed structures and their hydrocarbon accumulation are analyzed. Taking the gold belt oil field as an example, this paper makes use of the newly processed high quality 3D seismic data to describe the structural characteristics of the area, analyze the evolution of the stress field, and discuss the controlling effect of the structure on the oil and gas reservoir forming conditions. It is considered that there is an extensional tectonics in the third stage of Sha in this area, and that the Dongying period is a strike-slip structural deformation system, and the maximum principal compressive stress direction is near east-west direction, which is manifested by the north-east right-lateral strike-slip. At the same time, the direction of the local stress field is changed by the fault of the second boundary as the boundary of the tectonic belt. The results show that the extensional structure, strike-slip structure, compressional structure and reverse structure are all developed in this area under complex stress conditions, and there are special structural phenomena: the strike of fault and fold hinge appears regular gradual change. Dolphin effect exists in the horizontal section of strike-slip fault. Combined with the variation of the regional stress field and the influence of the boundary of the tectonic belt, the structural deformation superposition and the complicated pre-existing structural conditions are the causes of the complex structural phenomena. Tectonic activity coincides with hydrocarbon accumulation in time, which plays an important role in hydrocarbon accumulation and preservation.
