【摘要】：羊二莊油田位于黃驊坳陷羊二莊鼻狀構(gòu)造東北部,為趙家堡斷層下降盤上的一個逆牽背斜(穹隆背斜)構(gòu)造。鉆探證實該區(qū)發(fā)育第四系平原組、上第三系明化鎮(zhèn)組和館陶組、下第三系東營組;主要含油層系為上第三系明化鎮(zhèn)組和館陶組。油田勘探初期是按構(gòu)造找油的思路,圍繞中央隆起帶上背斜、斷鼻構(gòu)造進行勘探開發(fā)。從目前的鉆探現(xiàn)狀看,構(gòu)造帶主體已全面開發(fā),必須按照巖性油氣藏勘探的思路,沿構(gòu)造周邊實施滾動擴邊外,尋找河道砂體巖性油氣藏,在羊二莊北斜坡鉆探的莊83井,在明化鎮(zhèn)見到良好的油氣顯示,展示了斜坡區(qū)巖性油氣藏勘探的前景。羊二莊地區(qū)受物源、古地形、構(gòu)造背景的影響發(fā)育河流相沉積體系,屬于砂泥巖儲蓋組合,尋找河道砂體,進行鉆探,擴大含油面積,提高油氣儲量。首先多井聯(lián)合標定,井震吻合,搞清河道砂體地震反射特征,利用重新處理的新資料,進行精細構(gòu)造解釋,在正確的地質(zhì)框架上進行儲層預(yù)測,采用多屬性聯(lián)合反演,尋找敏感參數(shù),結(jié)合地層切片、三維可視化、種子點自動追蹤等技術(shù),在羊二莊地區(qū)發(fā)現(xiàn)不同層系50多條河道砂體,最后分析河道砂體的油源條件、油氣運移方式、蓋層和側(cè)向封堵條件,并利用頻率衰減屬性進行含油氣預(yù)測,優(yōu)選多口井位,指導勘探部署。
[Abstract]:Yangerzhuang oilfield is located in the northeast of Yangerzhuang nose structure in Huanghua depression, which is a reverse traction anticline (dome anticline) on the descending plate of Zhaojiapu fault. The development of Quaternary plain formation, Upper Tertiary Ming Hua Zhen formation and Guantao formation, and Lower Tertiary Dongying formation is confirmed by drilling, and the main oil-bearing strata are Upper Tertiary Minghua Zhen formation and Guantao formation. In the early exploration of oil field, the exploration and development of the anticline and fault nose structure in the central uplift zone were carried out according to the idea of structural oil exploration. In view of the present drilling situation, the main body of the structural belt has been fully developed, and it is necessary to carry out rolling expansion along the periphery of the structure to search for lithologic reservoirs in the channel sand body in accordance with the idea of lithologic oil and gas reservoir exploration, and to drill well Zhuang83 on the northern slope of Yangerzhuang. A good oil and gas display is seen in Minghua town, which shows the prospect of lithologic oil and gas exploration in slope area. The fluvial facies sedimentary system is developed in Yangerzhuang area under the influence of provenance, paleogeography and tectonic background, which belongs to the combination of sand and mudstone reservoir and cap, looks for channel sand body, carries out drilling, expands oil-bearing area and improves oil and gas reserves. First of all, multi-well joint calibration, well seismic coincidence, clear channel sand body seismic reflection characteristics, using reprocessed new data, fine structure interpretation, reservoir prediction on the correct geological framework, using multi-attribute joint inversion, Searching for sensitive parameters, combining the techniques of stratigraphic slicing, 3D visualization and automatic tracing of seed points, more than 50 river channel sand bodies with different strata are found in Yangerzhuang area. Finally, the oil source conditions and oil and gas migration modes of channel sand bodies are analyzed. The caprock and lateral plugging conditions are used to predict oil and gas with frequency attenuation attribute, and multiple wells are selected to guide exploration and deployment.
