岩石热解录井在松辽盆地南部新区勘探中的应用

Rock pyrolysis logging in the exploration in the new area of Liaohe Oilfield

岩石热解录井技术已在多数油田重点探井得到广泛应用,通过对岩石热解录井分析参数地质意义研究,结合松辽盆地南部新区油气勘探特点,提出岩石热解录井应在钻井现场开展快速评价烃源岩有机质丰度、类型以及烃源岩成熟度的工作,从而快速提高评价新区的勘探潜力,综合评价储集层及原油性质,有利于提升新区油气勘探信心,快速确定试油、试气及开采工艺技术方案。实际应用情况表明,岩石热解录井技术对加快新区油气勘探及评价具有重要意义。

Rock pyrolysis logging technology has been widely used in key exploration wells in most oilfields,by studying the geological significance of the analysis parameters of the rock pyrolysis and combining with the oil and gas exploration characteristics in new area of Liaohe Oilfield,the authors proposed the pyrolysis logging should be used in the drilling site to rapidly evaluate the organic abundance,type,and maturity of the hydrocarbon source rock,thus to realize quick evaluation for the potential of new exploration area,comprehensive evaluation for the reservoir nature and oil properties.The oil and gas exploration confidence in the new area can be enhanced,and the oil test,gas test and the technical solutions of production technology can be quickly determined.Practical application shows that the pyrolysis logging technology has significance to accelerate oil and gas exploration and evaluation in the new areas.
