准噶尔盆地低阶煤煤层气资源及勘探潜力分析

探讨了目前国内外煤层气勘探开发和资源分布状况,研究了煤层气的成因、赋存特点和富集因素,在此基础上,结合准噶尔盆地中下侏罗统煤层的地质分布和演化特点,指出八道湾和西山窑组在盆地南缘最为发育,虽然演化主要处于低煤阶阶段,但含气率较高。煤岩的模拟实验亦证实,生气能力较强。借鉴美国开发低煤阶煤层气的成功经验,对煤层气成藏有利区进行了预测,认为:侏罗系西山窑组是勘探煤层气最有利层系,南缘东部是勘探煤层气最有利地区。

Tectonic and magmatic evolution of the active volcanic front in El Salvador: insight into the Berlín and Ahuachapán geothermal areas

In El Salvador, Central America, active deformation takes the form of a major dextral strike-slip fault system, the El Salvador Fault Zone, resulting from the oblique subduction of the Cocos Plate. The fault system is laterally discontinuous, being subdivided into different major en-echelon segments that partially overlap to form pull-apart structures. Volcanic activity is spatially confined to the fault segments and absent in the intervening pull-apart basins; no significant temporal gap exists in the erupted products, at least during the Plio-Quaternary. Detailed analyses within the geothermal fields of Berlín and Ahuachapán have revealed important volcano-structural and petrologic differences between the two areas. In the Berlín area active deformation is controlled by the regional transcurrent stress field, resulting in the development of systems of right-lateral E–W-trending strike-slip faults. Conversely, the structural setting of the Ahuachapán area is more complex, reflecting an interaction among different stress fields. Berlín products exhibit a marked geochemical and isotopic homogeneity indicating the presence of a single magmatic system. At Ahuachapán, on the other hand, the rocks display significant variations in both Sr isotopes and the LILE/HFSE ratios: this area is characterized by multiple volcanic centres, fed by different magma batches that reach the surface without reciprocal interactions in shallow reservoirs. Thus, the characteristics of the volcanic products at Berlín and Ahuachapán reflect their different tectonic settings, with important implications for geothermal investigations.     

1H n.m.r. technique for characterization of polymerized petroleum pitches

A new proton n.m.r. technique has been developed for the chemical characterization of polymerized petroleum pitches with pyridine-insoluble contents as high as 80%. The polymerized pitches were completely solubilized for conventional ¹H n.m.r. evaluation in a mixed solvent system consisting of S₂Cl₂-SO₂Cl₂. Although solubilization occurs via the addition of chlorine to the polynuclear aromatic rings, the n.m.r. spectra can still be quantitatively interpreted. Several applications are discussed.
