巴48北阿三段砾岩体精细油藏评价
|
摘要
巴48北阿三段砾岩体是在巴音都兰凹陷二次三维地震采集基础上,筛选出的有利目标之一。前期按照构造油藏的评价思路部署实施3口评价井,效果不理想,近2年按照岩性-地层油藏的评价思路,开展了5个方面的精细油藏评价具体做法,在砾岩体北部设计钻探了1口井,获高产工业油流,砾岩体油藏评价获得突破,形成了(2000～3000)×104t的整装规模储量,取得了显著的油藏评价效果。巴48北阿三段砾岩体精细评价的成功做法对二连盆地其他凹陷油藏评价具有一定指导和借鉴意义。
Ba 48north A ’ san Formation conglomerate body is one of the favorable targets from Bayindulan Depression based on the secondary 3Dseismic acquisition.In the early time,3appraisal wells are deployed in accordance with the evaluation of the structural reservoir.But the result is unsatisfied.For the recent two years,detailed reservoir evaluation is carried out according to the stratigraphic and lithology reservoir evaluation.A well is designed in the northern part of the conglomerate body which drilled with high-yield industrial oil flow.There is breakthrough of conglomerate body reservoir evaluation.Reserves of(2000～3000) × 10 4 t obtained and significant effect of reservoir evaluation is obtained.The successful fine evaluation practice of the Ba 48north A ’ san conglomerate body provides guidance and reference in some extent for reservoir evaluation of the other depressions in Erlian Basin.
