【摘要】：海安凹陷是江蘇油田實(shí)現(xiàn)油氣增儲上產(chǎn)的重點(diǎn)地區(qū),但隨著成熟老區(qū)勘探程度的提高,勘探領(lǐng)域由簡單構(gòu)造圈閉向復(fù)雜、隱蔽圈閉領(lǐng)域轉(zhuǎn)變,發(fā)現(xiàn)、落實(shí)有利圈閉的難度逐漸加大,對圈閉識別的技術(shù)方法也有了更高的要求。本文主要根據(jù)凹陷已有地震、地質(zhì)、測井及分析化驗資料,深入開展圈閉識別研究,按照構(gòu)造圈閉、隱蔽圈閉及淺層構(gòu)造圈閉三部分展開,其中泰州組圈閉識別是本文研究重點(diǎn),主要取得了以下成果:1.針對泰州組構(gòu)造油藏油氣運(yùn)聚有利區(qū)帶,開展構(gòu)造樣式分析及斷層綜合解釋,理順不同序級斷層組合關(guān)系,通過地震正演、相干體、數(shù)據(jù)融合等技術(shù),明確泰州組T40地震反射層反射特征及微小斷層的識別,對該地震反射層進(jìn)行精細(xì)解釋,發(fā)現(xiàn)和落實(shí)小斷層(微斷距)控藏圈閉。2.針對泰州組隱蔽油氣藏,在砂組精細(xì)對比基礎(chǔ)上,結(jié)合沉積微相研究和砂體展布特征分析,厘清泰州組砂體發(fā)育規(guī)律,通過地震屬性提取、分頻處理、波阻抗反演等技術(shù)識別隱蔽圈閉。3.通過對海安凹陷各次凹淺層的研究,結(jié)合曲塘次凹的發(fā)現(xiàn)成果,主要優(yōu)選了和其具有相似成藏條件的地區(qū),開展構(gòu)造精細(xì)解釋,落實(shí)淺層的有利目標(biāo)區(qū)和目標(biāo)塊。4.針對不同層系、不同類型圈閉進(jìn)行評價優(yōu)選,提供鉆探目標(biāo)。通過采用針對性的技術(shù)手段和方法,在該區(qū)解釋三維地震1104.09 km2,二維地震150km,并對幾個重點(diǎn)區(qū)域進(jìn)行了隱蔽圈閉的預(yù)測,發(fā)現(xiàn)了一批有利的構(gòu)造圈閉和斷層-巖性圈閉,為海安凹陷下步勘探提供有力保障。同時也建立了一套適合海安凹陷的小斷層及隱蔽圈閉預(yù)測的方法和技術(shù)流程。
[Abstract]:Haian sag is the key area in Jiangsu oil field to increase oil and gas reservoir, but with the improvement of exploration degree in mature old area, the exploration field changes from simple structural trap to complex, subtle trap, and it is found that, The difficulty of implementing favorable traps is gradually increasing, and the technical methods of trap identification have higher requirements. Based on the existing seismic, geological, logging and analytical laboratory data in the sag, the study of trap identification is carried out in depth, according to the structural trap. There are three parts of subtle traps and shallow structural traps, among which, the identification of Taizhou formation traps is the focus of this paper, and the following results have been obtained: 1. In view of the favorable zones of hydrocarbon migration and accumulation in structural reservoirs of Taizhou formation, Structural style analysis and comprehensive interpretation of faults are carried out to straighten out the relationship of fault combinations of different order levels. By means of seismic forward modeling, coherent volume, data fusion and other techniques, the reflection characteristics of seismic reflection layer T40 and the identification of small faults in Taizhou formation are clarified. The fine interpretation of the seismic reflection layer and the discovery and implementation of the small fault (micro-fault) controlled reservoir trap .2. aiming at the subtle reservoirs of Taizhou formation, on the basis of fine correlation of sand formation, combined with sedimentary microfacies study and sand body distribution characteristics analysis, To clarify the regularity of sand body development in Taizhou formation, identify hidden traps by seismic attribute extraction, frequency division processing, wave impedance inversion and so on. 3. Through the study of shallow layers of each depression in Haian sag, combined with the discovery results of Qutang subconcave, The main areas with similar reservoir forming conditions are selected to carry out fine structural interpretation, to implement the favorable target area and target block of shallow layer .4.To evaluate and select different types of traps according to different strata and different types of traps, To provide drilling targets. Through the use of targeted technical means and methods, this paper interprets 3D earthquakes 1104.09 km2 and two-dimensional earthquakes 150km2 in this area, and predicts hidden traps in several key areas. A number of favorable structural traps and fault-lithologic traps have been found, which provide a strong guarantee for the next step exploration in Haian Sag. At the same time, a set of methods and technical processes for prediction of small faults and subtle traps suitable for Haian Sag have been established.
