黔北正安区块牛栏组基于叠后地震属性的多尺度裂缝预测

黔北正安地区安场向斜石牛栏组为一套深水陆棚沉积的泥灰岩地层,前期钻探显示,石牛栏组气藏分布与裂缝发育程度密切相关,为典型的裂缝型气藏。为进一步对安场向斜石牛栏组储层的裂缝平面展布规律进行研究,该文通过岩心、成像测井等资料分析目的层的裂缝发育特征,优选裂缝预测敏感地震属性,基于地震像素处理的裂缝增强属性对石牛栏组裂缝分布进行了预测。研究结果表明:利用常规的地震曲率属性预测裂缝识别能力有限,而基于地震像素处理的地震数据能够有效改善小断层及构造形变特征成像,在此基础上开展的裂缝增强属性可大大提高裂缝的识别能力,经实钻井验证,基于叠后地震属性裂缝分布预测方法的结果与钻井泥浆漏失点综合吻合率达83.3%以上,预测结果较为可靠,该研究为石牛栏组区带优选及钻井风险预警提供了技术支撑。

鄂尔多斯盆地榆林－神木地区上古生界裂缝和断层分布及其对天然气富集区的影响

鄂尔多斯盆地东部榆林-神木地区上古生界发育了断层和3种类型的裂缝.裂缝类型有区域构造缝、水平缝（包括层理缝与缝合线）和成岩缝,其中,区域构造缝主要呈北东向分布,在上古生界各层位均发育,缝合线在山2段中下部和太原组灰岩中都可见到,层理缝仅见于山西组山2段中下部,成岩缝仅见于石千峰组千5段.断层为逆断层,断穿了上古生界下部气藏的区域盖层和烃源岩.裂缝和断层分布对研究区重点勘探层位山2段、盒8段和千5段的天然气富集起到了重要作用：伴生的层理缝和缝合线的分布控制了山2段天然气富集区;区域构造缝的分布促进了盒8段天然气的富集;而千5段天然气的富集则依赖于本区断穿上石盒子组的断层和区域构造缝的分布.图6表2参29

松辽盆地北部深层致密火山岩气藏天然裂缝分布特征及控制因素

天然裂缝系统控制了松辽盆地北部徐家围子断陷深层致密火山岩储层天然气的运移、聚集和成藏。明确致密火山岩储层天然裂缝主控因素是准确预测裂缝分布规律的基础。通过野外露头区裂缝描述、岩心和微观薄片裂缝分析,结合成像测井裂缝解释,对松辽盆地北部深层致密火山岩气藏中天然裂缝的发育特征进行了精细表征,并深入分析了裂缝分布特征及控制因素。研究结果表明,研究区致密火山岩中发育有原生和次生两大裂缝类型,其中次生构造裂缝最为发育,其线密度主要分布在1.0～5.0条/m,平均为2.45条/m。裂缝发育强度主要受岩石类型、岩石力学性质、岩石脆性和构造部位等因素控制。天然裂缝方位复杂多变,是受古构造应力、断层和岩石非均质性(面理)共同作用的结果。

Compatibility of 2, 4, 6, 8, 10,12-Hexanitrohexaazaisowurtzitane with a Selection of Insensitive Explosives

Thermal techniques (differential scanning calorimetry (DSC) and the vacuum stability test (VST)), according to STANAG 4147, and non-thermal techniques (Fourier transform infrared (FTIR) spectrometry and X-ray diffractometry (XRD)) were used to examine compatibility issues for 2,4,6,8,10,12-hexanitrohexaazaisowurtzitane (CL-20) with a selection of insensitive explosives, including nitroguanidine (NQ), 2,4,6-trinitrotoluene (TNT), 2,6-diamino-3,5-dinitropyridine-1-oxide (ANPyO), 2,4,6-triamino-1,3,5-trinitrobenzene (TATB), 3-nitro-1,2,4-triazol-5-one (NTO) and 2,6-diamino-3,5-dinitropyrazine-1-oxide (LLM-105). DSC measurements showed that ANPyO, TATB, NTO and LLM-105 were compatible with CL-20. The compatibility of CL-20/NQ, CL-20/TNT, CL-20/ANPyO, CL-20/TATB, CL-20/NTO and CL-20/LLM-105 mixtures was further explored using the VST, which revealed that all the selected insensitive explosives were compatible with CL-20. Possible chemical interactions were suspected for CL-20/TATB from the FTIR results and for CL-20/NTO from XRD analysis. In summary, ANPyO and LLM-105 demonstrated the optimal compatibility with CL-20.

Abstract

Eight shale samples related to the Duwi Formation (Campanian-Maastrichtian) of the Abu Tartur mines of the southwestern desert of Egypt were petrographically, mineralogically, and geochemically studied. The study results indicate that the detrital material of these shales were derived mainly from mafic to ultramafic components of the basement rocks under intensive chemical weathering and deposited in an alkaline reducing marine environment of low energy and these shales do not attain the requirements of hydrocarbon production.

Bulk Compositions,Genetic Origin,Classifications, and Maturation of Crude Oils in the Gulf of Suez,Egypt

Abstract

API gravity, sulfur content, gas chromatography, and gas chromatography-mass spectrometry analyses were carried out for eight oil samples collected from different wells in the Gulf of Suez. The results showed that two types of oils could be recognized: (a) heavy oils, which are oils from Zafarana, Rahmi, West Bakr, and Ras Gharib wells, are of low maturation and originated mainly from terrestrial organic sources; and (b) light oils, which are oils from Um El Yuser, Ras El Ush, Gemsa-SE, and Hurghada wells, have a high level of maturation and orginate mainly from marine organic sources.
