【摘要】：安達(dá)向斜位于大慶市東南,在構(gòu)造上位于松遼盆地北部中央坳陷區(qū)三肇凹陷的北部,西接大慶長(zhǎng)垣、東臨明水階地,北為黑魚(yú)泡凹陷。作為濱北地區(qū)與三肇凹陷的過(guò)渡帶,主要目的層為扶余油層。盡管在安達(dá)向斜巖性油藏的勘探近幾年雖取得了長(zhǎng)足進(jìn)步,但是,由于該地區(qū)跨多個(gè)油氣運(yùn)聚單元,致使不同區(qū)域、不同構(gòu)造位置的油氣分布規(guī)律、成藏主控要素不明確,使得對(duì)周邊地區(qū)的資源前景認(rèn)識(shí)不夠深入,嚴(yán)重制約了周邊地區(qū)的勘探步伐。通過(guò)本項(xiàng)目研究及科技攻關(guān),建立了安達(dá)向斜超壓控深—斷裂控邊的斷壓雙控成藏模式。安達(dá)向斜斷裂密集、復(fù)雜,側(cè)向封閉性較好,儲(chǔ)層砂體連續(xù)性較差,不具備遠(yuǎn)距離運(yùn)聚條件。同時(shí),構(gòu)造發(fā)育史研究表明,安達(dá)向斜受構(gòu)造調(diào)整,明末沉積時(shí)期沉積中心位于現(xiàn)今沉積中心的西側(cè),與現(xiàn)今油氣顯示匹配,油氣分布受控于古沉降中心。在上述分析基礎(chǔ)上,明確了安達(dá)向斜的油氣成藏區(qū)帶。因此通過(guò)對(duì)安達(dá)向斜自身石油地質(zhì)條件及成藏規(guī)律的研究,一方面可以揭示安達(dá)向斜自身的油氣成藏規(guī)律及勘探潛力,同時(shí)也可以進(jìn)一步明確對(duì)周邊地區(qū)小型凹陷致密油的勘探部署思想,為后期周邊地區(qū)致密油儲(chǔ)量的整體認(rèn)識(shí)和提升儲(chǔ)量品質(zhì)提供技術(shù)支撐。
[Abstract]:The Anda syncline is located in the southeast of Daqing city, structurally located in the north of Sanzhao sag in the central depression of north Songliao basin, in the west of Daqing Placanticline, in the east of Mingshui terrace, and in the north of black fish bubble sag. As a transitional zone between Binbei area and Sanzhao sag, the main target layer is Fuyu reservoir. Although great progress has been made in the exploration of lithologic reservoirs in the Anda syncline in recent years, due to the migration and accumulation of oil and gas across many units in this area, the distribution of oil and gas in different regions and different structural positions is not clear, and the main controlling elements of reservoir formation are not clear. It makes the understanding of the resource prospect of the surrounding area not deep enough, and restricts the exploration step of the surrounding area seriously. Through the research of this project and the research of science and technology, the overpressure-controlled deep-fault-controlled reservoir formation model of Anda syncline is established. The Anda syncline is characterized by dense faults, complex faults, good lateral sealing, poor continuity of reservoir sand bodies and no conditions for long-range migration and accumulation. At the same time, the study of tectonic development history shows that the depositional center of Anda syncline is located on the west side of the present sedimentary center in the late Ming Dynasty, which matches the present oil and gas display, and the distribution of oil and gas is controlled by the paleo-subsidence center. On the basis of above analysis, the hydrocarbon forming zone of Anda syncline is defined. Therefore, through the study of the petroleum geological conditions and reservoir formation laws of the Anda syncline, on the one hand, the oil and gas accumulation law and exploration potential of the Anda syncline can be revealed. At the same time, the idea of exploration and deployment of compact oil in the surrounding small depression can also be further clarified, which can provide technical support for the overall understanding of the compact oil reserves in the surrounding areas and the improvement of reserve quality.
