大庆油田杏南开发区表外储层分类和开发状况研究
|
摘要
大庆油田的储集层在漫长复杂的沉积过程中,不仅形成了高能环境下的沉积物,同时也形成了碎屑物质供应不足的低能环境下的沉积物。这种低能环境下的沉积物,主要以油斑、油浸产状为主的泥质粉沙岩,分布于高能环境沉积物的顶底周边及内部变差部位,通常不能被划为有效厚度界限以内,因而未被列入储量表内,被称为表外储层。采油五厂开发的杏南开发区层为松辽盆地中部含油组合的萨尔图、葡萄花油层,从上到下依次为萨II、萨III、葡I三个油层组。表外储层虽然单层厚度薄、面积小,但储量潜力较大,而且与好油层一般都是连通的。通过二次加密调整,使表外储层投入开发,提高了储量动用程度,增加了可采储量,改善了开发效果。但由于二次加密调整井的油层条件差,在目前开发下,有些方面没有达到动用要求,致使表外储层动用较差。表现为二次加密井吸水厚度低,产量递减大,含水上升快。虽然采取了一系列措施,但开发效果仍没有明显改善。
本文通过对国内外大量表外储层开发调整的调研,在低渗透储层非均质特征研究的基础上,对表外储层的渗流特点及动用影响因素进行了分类研究。通过对表外储层渗流机理、油层压力传导能力分析,得出了杏南开发区低渗透储层的动用条件。在此基础上对低渗透储层开发的合理井距、层系优化、提高采收率方法等多方面进行了研究。对进一步改善表外储层开发效果及三次加密调整具有重要意义。
It is not only formed sediment in high energy circumstance,but also formed sediment in low energy circumstance of oddment substance in short supply in the reservoir of Daqing oilfield complicated and perennial deposit process. And the sediment in low energy circumstance mainly is argillaceous siltstoue of oil patch or oil immersion,commonly distributing atop or down below or in the interiorly of the attenuation. And the thickness commonly can not be defined as virtual value,and so can not be fallen under dividing line, so go by the name of thin and poor layer.The XingNan Development Area of the fifth oil-extraction is exploit Saertu and Putaohua layer of the Songliao basin .From the top down in turn is SaII、SaIII、PuI layer group.Although the thin and poor layer has low thickness and little proportion,but has great reserves potential. Moreover it is connected with the thickness generally. After secondary infilling adjustment, the thin and poor layer launched into exploitation, improved pay-gross thickness ratio, increased recoverable reserves,the development effect of Xingnan development area was improved. But on account of the poor reserves conditions,some aspect couldn’t meet the needled to its poor employed. For example,the absorbing thickness of secondary infilling adjustment wells were low,and production decline was quick,and water content moved upward quickly.Though a series of measure were adopted,the development effect was not improved evidently yet.
Through investigation of adjustment reservoir of a large number of the thin and poor layer from both home and abroad,this paper referred to the classification of factors of its flow characteristics and the impact factors on the base of the detail analysis of the characteristics of low-permeability reservoir heterogeneity.Through analysis of the permeability mechanism and the capacity of reservoir pressure conduction,came to the conclusion of use conditions of thin and low-permeability reservoir in XingNan Development Area. On this basis the development of low-permeability reservoir of the reasonable well spacing, layer optimization, enhanced oil recovery methods have been studied and so on.. It is of great significance to further improve the thin and poor layer effects of reservoir development and third infilling adjustment .
Table outside the reservoir through the permeability mechanism, the capacity of reservoir pressure conduction analysis of the development zone Xingnan the use of low-permeability reservoir conditions.On this basis the development of low-permeability reservoir of the reasonable well spacing, layer optimization, enhanced oil recovery methods have been studied and so on.. To further improve the balance-sheet effects of reservoir development and adjustment of the three encryption of great significance.
