Hydrocarbon accumulation in deep fluid modified carbonate rock in the Tarim Basin

The activities of deep fluid are regionalized in the Tarim Basin. By analyzing the REE in core samples and crude oil, carbon isotope of carbon dioxide and inclusion temperature measurement in the west of the Tazhong Uplift in the western Tarim Basin, all the evidence confirms the existence of deep fluid. The deep fluid below the basin floor moved up into the basin through discordogenic fault and volcanicity to cause corrosion and metasomatosis of carbonate rock by exchange of matter and energy. The pore structure and permeability of the carbonate reservoirs were improved, making the carbonate reservoirs an excellent type of deeply buried modification. The fluorite ore belts discovered along the large fault and the volcanic area in the west of the Tazhong Uplift are the outcome of deep fluid action. Such cap bonate reservoirs are the main type of reservoirs in the Tazhong 45 oilfield. The carbonate reservoirs in well YM 7 are improved obviously by thermal fluid dolomitization. The origin and territory of deep fluid are associated with the discordogenic fault and volcanicity in the basin. The discordogenic fault and volcanic area may be the pointer of looking for the deep fluid modified reservoirs. The primary chap acteristics of hydrocarbon accumulation in deep fluid reconstructed carbonate rock are summarized as accumulation near the large fault and volcano passage, late-period hydrocarbon accumulation after volcanic activity, and subtle trap reservoirs controlled by lithology.     

东营凹陷不同沉积层序的输导体系结构特征

针对东营凹陷的地质特征,利用输导体系综合研究方法,分析了盆地输导体系的构成,发现东营凹陷不同沉积层序在输导体系结构特征上存在差异性:①深部沉积层序(Ek-Es4)输导特征主要表现为砂体侧向复式输导.边缘带输导体系要素主要为砂体,且以侧向输导为主,在深部层序中属于主要输导体系.洼槽带输导体系要素单一,为断裂垂向单一输导,在深部层序中属于次要输导体系.②中浅部沉积层序(Es3-Ed)的砂体、断裂在盆地中都十分发育,输导体系类型多样,包括断裂-不整合型、砂体-断阶型、网毯式-断裂型、简单砂体-断裂型、阶梯型及不整合型输导体系,输导特征主要表现为砂体-断裂多向复式输导.③从深部沉积层序到中浅部沉积层序,输导方向变多,输导特征总体上由简单输导向复式输导逐渐变化.     

Discussion on marine source rocks thermal evolvement patterns in the Tarim Basin and Sichuan Basin, west China

Taking marine source rocks of lower Paleozoic in the Tarim Basin and Paleozoic ones in the Sichuan Basin as examples, their sedimentation process could be classified into four styles continuous subsldence with deep sedimentation in early stage, continuous subsidence with deep sedimentation in later stage, that deeply buried-uplift-shallowly buried, and that shallowly buried-uplift-deeply buried.Unlike that in East China, the marine source rocks evolvement patterns did not accord with sedimentation styles one by one in superimposed basins in west China. Taking local geothermal field into account, four types of source rock evolvement patterns were built that evolved fast in early stage,evolved fast in middle stage, evolved continuously and evolved in multistage. Among them, the 1st pattern contributed little to the present industrial oil pools directly, but paleo-oil reservoirs and gases cracked from crude oils were main exploration targets. Although some gases were found in the 2nd pattern, the scale was not big enough. For the 3rd and 4th patterns, the hydrocarbon potential depended on organic matters maturity in early stage. For relatively low mature rocks, it was possible to generate some oils in later stage; otherwise the main products were gases. Paleo-oil reservoirs remained fairly well in the Sichuan Basin, and most source rocks underwent kerogen-oil-gas processes,which was useful reference to gas exploration in the Tarim Basin.     

沉积盆地岩性地层圈闭成藏主控因素分析

随着世界油气勘探技术的发展和理论研究的不断深入,在新发现的油气藏中岩性地层油气藏无论是产量还是储量上都占有重要地位.因此,对这类油藏的理论研究一直是国内外石油地质学家研究的重要内容.本文认为岩性地层圈闭与构造圈闭在成藏条件和成藏机制方面存在一定差别,岩性地层圈闭的形成条件复杂,决定了其成藏主控因素具有自身的特点.提出了岩性地层圈闭成藏“四元主控”观点:即运移通道条件、流体动力条件、储层临界物性特征和砂体封闭条件.这4项主控因素控制和决定了岩性地层油气藏的形成.

Characteristics of hydrocarbon source rocks of No.3 buried-hill region in Nanpu Sag

Based on the data of 44 samples of hydrocarbon source rocks in Nanpu No.3 buffed-hill region, the kerogen type is judged through the pyrolysis and microscopic identification. At the same time, organic matter maturity and hydrocarbon generation threshold are studied by using vitrinite reflectance, pyrolysis yield and hydrocarbon abundance. Meanwhile the hydrocarbon expulsion threshold is calculated. And the characteristics of organic hydrocarbon generation and expulsion are preliminarily revealed and evaluated. The result shows that the No.3 buffed-hill region has abundant hydrocarbon source rocks with high content of organic carbon. And the primary types of kerogen are II, and lI 2. The hydrocarbon source rocks which passed biochemistry, thermolysis and thermal cracking have developed into the mature-postmature phase of different extents. And plenty of oil and gas were expelled out. It is believed the depth of oil-generating window is 3 600 m and the depth of hydro- carbon-expulsion threshold is 4 100 m. The comprehensive analysis indicates that Nanpu No.3 burried-hill region has a certain condition to generate hydrocarbon which is very promising in oil exploration and thus can become an important exploration and development target next.
