红南油田喀拉扎组储层测井评价

Reservoir Logging Evaluation of J_3k Group in Hongnan Oilfield

红南油田于20世纪80年代投入勘探开发,并且在白垩系和中侏罗统均取得了工业油流,而红南喀拉扎组油藏在2004年7月才被发现,这充分说明它是一个典型的隐蔽性油气藏,具有较高的研究价值。通过对其储层四性关系、油藏特征等方面深入研究,从隐蔽的储集空间和流体性质两方面,剖析了隐蔽性油气藏的成因,在此基础上,建立了一套针对性较强的细岩性低阻低丰度油气层识别方法,可以作为隐蔽型油气藏勘探开发的配套技术。

Hongnan oilfield was put into exploration development in 1980s. with industrial oil flow in Cretaceous and Middle Jurassic. Reservoir of J3k Group in Hongnan oil_field was only discovered in July, 2004, so it fully proved that it is a subtle reservoir with high research value. Through study on relationship of lithology, physical property, water and oil - bearing property of reservoir, reservoir characteristics, the genesis of subtle reservoir is analyzed from the reservoir pore space and the fluid property. Based on the analysis, a set of methods for identifying oil and gas reservoir with fine lithology, low resistivity, low abundance are established, which can be used as a matching technique of exploration development for subtle reservoir.
