Very thick, fine-grained quartzose sandstone of the Lower Carboniferous (called the Donghe sandstone) was discovered in Donghe-1 well in the tarim basin. Highly-productive commercial oil and gas flows were obtained when a well completion test was conducted. This important discovery proved that the quartzose sandstone is a prospecting target with good prospects. After that, other two paying oil and gas flows were found in the Lower Carboniferous in the Tazhong-4 and Tazhong-10 structures (Tazhong means central tarim), equivalent to the Donghe sandstone. The Tazhong-4 structural oil {2. is the biggest oil {2. ever discovered. Therefore it is of guiding importance in oil and gas exploration to deepen the study of sedimentary and reservoir features and the sedimentary environment of the Donghe sandstone and to build a sedimentary model in order to understand the reservoir distribution pattern.

The Silurian in the tarim Basin was deposited on the basement deformed by the Caledonian tectonic movements at the end of the Late Ordovician. The development and distribution of sedimentary sequences of the Early Silurian have been clearly controlled by the palaeogeomorphology of the Late Ordovician. Based on unconformity characteristics and distribution of erosion, several zones can be differentiated including a high uplifted erosion zone, a transitional slope zone and a depression zone. The central and west Tabei Uplift zones show high angular unconformity and intense erosion. The tarim Basin in the late Ordovician shows characteristics of higher in the west, lower in the east while higher in the south, lower in the north. The Early Silurian mainly developed transgressive and highstand systems tracts on the whole, while the lowstand systems tract only developed partly below the slope break. The palaeogeomorphology controlled the elastic source supply and deposit distribution. Braided delta system and tidal flat-estuary system were deposited. The duration of uplifting of the Tazhong paleo- uplift was longer than that of the Tabei paleo-uplift, and deposition was later. This led to the lower and middle members of the Kepingtage Formation missing in that area. As a large-scale transgression occurred during the deposition period of the upper member of the Kepingtage Formation, sediment from the west of the basin was transported and deposited by tides and waves, forming tidal-marine debris systems above the uplift. Proximal alluvial fan and fan delta coarse elastic deposits developed in proximal uplift zone in the east and southeast of the basin, and braided delta put forward to the transitional zone between the edge of uplift and the sea. Large-scale tidal channel, sub-distributary channel and mouth bar of the delta front can form favorable reservoirs, and they are primary targets for oil and gas exploration.

由于CO2.体与常规天然气性质存在较大差异,使得富含CO2.气藏与常规气藏相态特征不同,导致CO2.量影响气藏的开发指标的变化。为此,以校正过相态的计算模型为基础,研究了等温条件下不同CO2.量天然气相态变化特征、不同温度下含CO2.然气相态变化特征及相态变化对开发指标的影响。结果认为:无论是气藏渗流还是井筒流动过程中,富含CO2.火山岩气藏的相态计算都必须考虑偏差因子、黏度和密度随CO2.量的变化;在压力小于30 MPa时,井筒流动要考虑体积系数的变化;气藏的稳产期、稳产期末采出程度和预测期末采出程度随CO2.量的增加不断降低。该研究成果对富含CO2.然气藏的开发具有指导意义。

构造运动、全球海平面变化和气候的相互作用控制了沉积物供给量以及可容空间被充填的规模。在强制海退情况下的缓坡边缘上 ,相对海平面下降期间过路沉积物未被输送到盆底 ,而被沉积为一组逐级下降的前积楔 ,形成强制海退体系域。塔里木盆地满西区块的东河砂岩等时段是基于东河砂岩段上部和下部所存在的层序界面 (不整合面 )而划分的 ,具有等时性 ,但岩性、岩相在不同位置、不同地区会有变化。东河砂岩等时段所属的层序SQ 1的层序界面是海平面长期下降的结果 ,并受到构造运动的加强作用 ,表现为一个盆地范围内广泛发育的不整合面。层序SQ 1的发育演化明显受到海平面变化的控制 :在海平面快速上升时期发育海侵体系域 ;在海平面缓慢下降时期发育强制海退体系域。满西地区的东河砂岩是强制海退体系域的沉积产物 ,是在海退背景下发育的复合砂体 ,其展布非常复杂 ,多数呈点状或块状展布。层序SQ1的油气储集体主要分布于海岸带附近 ,它们是前滨—临滨沉积砂体。

Combined with oil and gas transport and accumulation, structure-lithology evolution history, and with geochemistry and synthesizing geology methods, this paper studies the oil and gas discharge history of Puguang large scale gas field and the main controlling factors of oil accumulation. The natural gas in Puguang gas field is mainly coal-derived gas and oil-racked gas. The main hydrocarbon is Upper Permian coal mudstone and Lower Silurian mud shale with organic material. Puguang gas field has gone through discharge and adjustment 3 times, and it has favorable palaeostructure location, high quality dredge and effectively conserving conditions.
