摘要? 塔里木盆地具有構(gòu)造演化旋回多、烴源巖發(fā)育層系多,、油氣成藏期次多,、油氣藏破壞次數(shù)多等特點，油源普遍混淆,，已發(fā)現(xiàn)油氣藏以它源油氣成藏體系為主,，難以通過單油源含油氣系統(tǒng)來解決油氣成藏的認(rèn)識問題。論文以塔中低凸起石炭系油氣藏為研究對象,，引入“網(wǎng)毯式油氣成藏體系”理論,，剖析了油氣成藏體系結(jié)構(gòu)及特征，揭示了油氣輸導(dǎo)體系,。結(jié)果表明：塔中低凸起石炭系發(fā)育CIII,、CI兩套次級成藏體系單元，各成藏體系單元結(jié)構(gòu)包括油源通道網(wǎng)層,、倉儲層,、油氣聚集網(wǎng)層等三層結(jié)構(gòu)；油氣輸導(dǎo)體系劃分為四類十一型,，即斷裂輸導(dǎo)型,、不整合輸導(dǎo)型、連通砂體輸導(dǎo)型及火山巖輸導(dǎo)型,，輸導(dǎo)模式包括“Y”型,、“T”型及“S”型等。塔中低凸起為典型的復(fù)合網(wǎng)毯式油氣成藏體系，成藏體系結(jié)構(gòu)和輸導(dǎo)體系的建立為石炭系油氣藏滾動開發(fā)拓展了新的思路,。

Abstract：

　　The Tarim Basin has generally undergone complex evolution with polycyclic tectonic events, and it has multiple layers of source rocks. It has had multiple periods of hydrocarbon accumulation and reservoir destruction. Mixed oil is common and distal source accumulation systems prevail. As a result, it is difficult to pick up a single-source system to help understand petroleum accumulation. Under the guidance of the meshwork-carpet structural petroleum accumulation model, the structure and transportation system of the Carboniferous in the central Tarim uplift was analyzed. The petroleum accumulation system is formed by two lower unit levels, and each unit has a three layered structure, namely channel-net layer, storage layer and accumulation layer. The conductive system can be divided into 4 classes and 11 types, such as faults, unconformities, connected sands and volcanic rocks. The transportation model has “Y”-shaped, “T”-shaped and “S”-shaped segments. The model of the central Tarim uplift is a typical meshwork-carpet structural petroleum accumulation system, and it provides new ideas for exploration and development of reservoirs.
