【摘要】 台吉乃尔气藏并不严格受背斜控制,而是背斜背景上的岩性气藏。这与前人所认为的三湖地区第四系天然气分布严格受低幅度同沉积背斜控制的结论有所差距。台吉乃尔含气地震异常平面分布范围、形态与背斜不一致;其次,k5标准层的优质储层发育不受背斜控制;第三,k5标准层气藏是一个背斜背景上的岩性气藏;第四,台中2井气藏是砂岩上倾尖灭气藏。台吉乃尔构造的气体具有混源特征,生气强度大,目前该地区岩性气藏勘探程度低,勘探潜力大,建议加强岩性气藏成藏规律研究,加强岩性气藏及背斜背景上的岩性气藏等复合气藏的勘探力度。更多还原

【Abstract】 Gas accumulation of the Taijinaier structure is not a structure gas reservoir but a non structure gas reservoir under anticline environment on the basis of the study. This cognition may be inconsistency to the conclusion that the gas reservoir is under the domination of the lower range anticline in the Sanhu area. The reasons to the cognition as follows: the first is that the shape and it’s extension of the seismic abnormity is not consistent to the anticline; the second, the high quality reservoir’s development is not under the control of the anticline in the k5 standard layer; the third, the gas accumulation is a non structure gas reservoir under the environment of the anticline in the k5 standard layer; finally, the gas accumulation of the well Taizhong2 is a gas reservoir of the sand vanish in the upper way. The gas of the Taijinaier structure has the characteristic of the commixture, there is a high intensity of gas production in the study area. At present there is lower non structure gas reservoir exploration degree, so it has a high exploration potential. It pointed out that we should reinforce the study degree of the rule to the non structure gas reservoir. At the same time, we should reinforce the exploration degree of the non structure gas reservoir and it’s correlation gas reservoir.更多还原
