摘要
运用准噶尔盆地西北缘拐16井油气藏的地震、试油、测井、钻井等资料,从沉积特征、储层物性和非均质性、含油气性等方面对G3016井开发失利的原因进行了研究。研究结果表明,开发失利的原因不是完井工艺等非地质因素,而主要是由于G3016井储层物性变差、非均质性增强造成。在拐16井区油藏形成时,只有极少部分油气进入G3016井储层,使其有一定程度的油气显示,但是未能形成工业油流。基于开发失利原因的分析,结合断层、局部构造、井斜、油藏构造、地表条件、气顶分布情况以及边水位置等,提出了该区的滚动勘探开发建议,已被生产部门认可。
Using the seismic data,the production test data, the logging data,and drilling data etc.of Well Guai 16 reservoir in the northwest margin of Jungar Basin,the study is conducted on the sedimentation features,the reservoir physical property,the heterogeneity,and the oil/gas bearing property etc.for the reasons why the development of Well G3016 is failing.The results show the reasons of the development failure are not the non-geological factors such as the well completion technology etc.,but are the reservoir physical property is deteriorated and the heterogeneity is increased in Well G3016.When Well Guai 16 reservoir is formed,there is few oil and gas entering the Well G3016 reservoir,which make the well has oil/gas show but no commercial production.Based on the reason analysis of development failure,according to faults,local structure,well deviation,reservoir structure,surface conditions,gas cap distribution,and edge water position etc.,the advices of progressive exploration and development are proposed for the region,which have been accepted by the management.
