限定了井眼方向的待钻井眼轨道设计问题需要求解一个7元非线性方程组,通常使用的数值迭代方法有许多固有的缺点,提出了一个新方法──代数法:将原始非线性方程组化简成一个三元多项式方程组,再进一步归结为求一个10次多项式方程全部正实数解问题和一个二元线性代数方程组问题。给出了代数法的计算机实现方法,具有计算速度快、数值稳定性好、存储需求小等特点。代数法具有与解析法相近的良好数学性质,能够对问题是否有解做出事前判断;在问题存在多个解的情况下,能够正确求出全部的解。所使用的数学化简技巧能够推广应用到求解定向井、水平井的井眼轨道设计问题中,有重要的理论价值和应用前景。

Sixty-five natural gas samples were collected from 19 oil-gasfields in theQaidam basin, china. The chemical composition and carbon isotope values of the samples weremeasured, and the geochemical characteristics and origin of the natural gases were studied. Thegases can be divided into biogenic gases, sapropelic oil-type gases, mixed type oil-type gases,coal-type gases and mixed gas. The delta^(13.C_1 values of the biogenic gases are very small and theC_2^+ contents of them are very low, ranging from -68.2 per thousand to -61 .8 per thousand and0.06 percent to 0.20 percent respectively. They have heavy delta D and delta^(13.C_(CO_2), showing aCO_2 reduction pathway. They ,are distributed in the East depression region and derived from theQuaternary source rocks. The sapropelic oil-type gases have small delta^(13.C_2 values and highC_2^+ ranging from -3..6 per thousand to -28.6 per thousand and from 3..01 percent to 47.15 percentrespectively. The mixed type oil-type gases have delta^(13.C_2 values and C_2^+ contents varyingfrom -28.6 per thousand to -24.8 per thousand and from 4.81 percent to 26.06 percent *** sapropelic oil-type gases and mixed type oil-type gases are associated with oil-type oils,distributed in the West depression region and derived from the Tertiary saltwater lacustrinesapropelic source rocks and humic source rocks respectively. The delta^(13.C_2 values of thecoal-type gases are extremely high and the C_2^+ contents are very low, changing from -23.3.perthousand to -12.5 per thousand and from 0.06 percent to 18.07 percent respectively. The coal-typegases in the Nanbaxian gasfield and the Lenghu oil-gasfields in the North fault block belt arederived from the Middle Jurassic coal-measures source rocks, whereas those in the West depressionregion are derived from the Tertiary saltwater lacustrine humic source rocks. Compared with someother basins in china, the natural gases there have obviously heavier delta^(13.C due to the heavierdelta^(1

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.

通过对流变仪温控原理的研究,分析了行业标准《原油析蜡点的测定旋转黏计法》中采用连续降温方式的不合理性,建议采用分段降温的方式。在低温段曲线呈非线性关系的情况下,若按照标准推荐的计算析蜡点软件计算,会造成析蜡点偏小或偏大。为此,提出了按照低温段曲线偏离高温段拟合直线的程度,判断析蜡点的改进意见。

Based on the migration track of the Silurian oil pools along the faults in central Tarim by the nitrogen compounds and the maturity parameters of saturated hydrocarbon and aromatic hydrocarbon, the formation of the Silurian oil pools was totally concerned with vertical migration that faults were the dominant migration channels. The comprehensive analysis shows that the dominant geological element, which contributed to the migration and accumulation of the Silurian oil pools in central Tarim, was the strike-slip fault, which developed from Ordovician to Permian. The future work will focus on conducting a more intensive study of the formation, evolution and distribution of the strike-slip faults for making sure of favorable hydrocarbon accumulation and favorable exploration targets.

准噶尔盆地车拐地区长期处于三大生烃凹陷油气运移的有利指向区。该区断裂及圈闭发育,具有多源、多期的油气成藏特征。通过对该区油源研究,发现车拐地区油气源分布具有明显的规律性。搞清了车拐地区各区带在不同时期的石油运聚特征。红车断裂自海西运动末期就开始发育活动,到燕山运动中晚期才停止活动,对早期(早中侏罗世之前)成藏起到破坏作用,对后期(早白垩世末)油气成藏起到封闭作用。车排子隆起区白垩系、石炭系勘探风险较大,但红车断裂带南段及下盘斜坡区、沙门子鼻凸侏罗系勘探前景较好。

由于CO2气体与常规天然气性质存在较大差异,使得富含CO2的气藏与常规气藏相态特征不同,导致CO2含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含量天然气相态变化特征、不同温度下含CO2天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的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含量的变化;在压力小于3. 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含量的增加不断降低。该研究成果对富含CO2天然气藏的开发具有指导意义。
