We analyze the excess area and depth to detachment method developed by Epard and Groshong （1993., and apply it to the sand box model of Ge et al （2004） to illustrate that inadequate consideration will affect the calculation of true depth to detachment. Using the data of Yu et al （2006） to fit linear regression lines, we obtain the depths to detachment of Kela-2, Misikantage anticline and Dongqiu-8 structures, 115.74km, 14.17km, and 75.48km below the reference level （Cretaceous bottom） respectively with the excess area intercept equal to zero. However, the calculation results of depth to detachment in Yu et al （2006） are based on excess area intercept unequal to zero.

大庆油田西部英台地区白垩系三角洲前缘粉砂岩储层中发育大量毫米级泥质薄层——泥膜,厚度在3.m以内。泥膜主要发育在三角洲前缘席状砂环境中,河口坝次之,水下分流河道中最少。根据岩芯观察统计,英台地区席状砂储层中的泥膜最大发育频率可以达到48条/米,频繁发育的泥膜在开发时能够改变砂岩内部的油水运移路线,间接起到了降低砂岩孔渗特征的作用。通过对同一个油藏模型在发育和不发育泥膜两种情况下开发特征进行数值模拟的结果对比,定量确定了泥膜的存在对含水率、采出程度和开发周期的影响,并对英台地区的泥膜发育情况提出了针对性的开发应对措施。

The Ordovician system is an important target for exploration in the Tarim Basin. Restoration of the Ordovician tectono-depositional environment is a key basis for the study of the structural development history in Tarim block and the prediction of the favorable Ordovician reservoir belts (zones). Based on the surrounding tectonic settings, the litho-facies and sedimentary fill, the palaeo-geography, palaeoclimate and palaeo-ecology, and the structural deformation and magmatic eruptions, in this paper we combine the sedimentary fill in the basin with the development of the surrounding orogenic belts and re-build the proto-type basins of the different Ordovician periods. During the Ordovician period, the Tarim region was characterized by the composite of the interior cratonic depression with the peripheral cratonic depression. The interior cratonic depression in the central and western parts is mainly the depositional area of the platform facies while the peripheral cratonic depression in the eastern part is mainly the zone of deepwater basin facies, with the slope acting as the transition belt between them. During the Late Ordovician period, the closure of the Northern Kunlun Ocean and destruction of the trencharc-basin system in the Altyn Tagh region put the southern part of the Tarim block under compression and uplifting and turned the central and western parts of the carbonate platform into the mixed depositional continental shelf. The eastern region of the basin had the over-compensated flysch sedimentation with huge thickness, marking the drastic turn of the basin nature. The basin tectonic framework turned to the south-north differentiation of the Silurian period from the east-west differentiation of the Ordovician period.

Absolute concentration of normal alkanes(n-alkanes) and aromatic hydrocarbons in bitumen extracted from source rocks in the period of thermodegradation from Turpan-Hami Basin suggests that aromatic hydrocarbons are dominant in coal and carbargilite while n-alkanes are dominant in mudstones. Bulkrock analysis and gas chromatograph/mass spectrum(GC-MS) of source rocks shows aromatic hydrocarbons are dominant in total ion chromatograms(TIC) of samples with poor perhydrous macerals while n-alkanes are dominant in TICs of samples with abundant perhydrous macerals. The identification of oil-prone and gas prone property based on GC-MS of bitumen "A" together with bulkrock analysis indicates that source rocks from Shengbei area are more oil-prone while source rocks from Qiudong and Xiaocaohu areas are more gas-prone,coinciding with the distribution of oil and gas reservoirs in Taibei Sag. Ratios used to identify oil-prone and gas-prone property for source rocks from Turpan Basin are proposed:n-alkanes >110 μg·mg-1,aromatics 8 for oil-prone source rock bitumen while n-alkanes40 μg·mg-1,and n-alkanes/aromatics <1.5 for gas-prone source rock bitumen.
