土库曼斯坦天然气资源丰富,是中亚地区最大的天然气生产国和出口国.通过调研该国油气资源、生产状况、石化工业概况、油气管线运输以及相关发展政策可以进一步了解该国能源状况.该国天然气和石油探明储量分别高达17.5×10”m3和10×108t,天然气出口管道主要有俄罗斯、伊朗、中国3个方向共4条管线,4大加工企业设计年处理油气总量约1 800×104t.加大油气勘探开发力度、提高油气产量、增强油气加工能力和积极吸引外资是其油气发展领域的主要政策.
通过对哈国石油开发方案的调研,重点对其中的油气开发方案的规范、油气田开发方案类型、开发方案的编制要求、申报报批程序进行了详细研究和总结;为在丝绸之路经济带区域投资哈国石油运营的中国企业和公司提供开发方案编制方面相关参考和帮助.
The output of Yingnan-2 well declines obviously after drilling,as well as the reservoir is seriously damaged.Therefore,it is necessary to evaluate reservoir damage and conduct research on protection measures.The analysis results of lithology,physical properties,pore feature,and clay components of reservoirs show that pores and throats are tiny and there is plenty of andreattite,which easily lead to serious sensitivity damage.Based on latent damage factors,the author runs water lock and different sensitive experiments.Results show that water lock,water sensitivity,pressure sensitivity are the main damage factors.A potassium base sulphonated polymer drilling fluid formulation is designed for preventing the water sensitivity damage.The static performance of the cores damaged shows that the permeability restoration of the cores is high.CO2 fracturing technique is suggested to be used,and formation pressure should be controlled appropriately.
对哈萨克斯坦国石油技术服务市场现状进行分析,提出一些开拓该国石油技术服务市场的认识和做法。
通过分析管柱从修井开始到抽油生产时液面下降引起的受力状态的改变,计算出管柱压在封隔器上的力改变,从而得出封隔器插管在抽油生产中不可能拔出的结论,进一步提出管柱配压重(长短)的新方法。
热采杆式泵的研究及应用能有效的解决稠油注蒸汽开发不动管柱注汽、抽油以及检泵的复杂难题,提高油井的抽油效率.文章阐述了对热采杆式泵密封锚定装置所做的计算研究工作.
应用热采杆式泵在克拉玛依油田抽油试验18井次,一次座泵、抽油、检泵成功率达到100%.结果表明,该泵的应用能有效的解决稠油注蒸汽开发不动管柱注汽、抽油以及检泵的复杂难题,满足注汽过程中测温、测压以及测吸汽剖面,提高了油井的抽油效率,这种泵与其它注抽两用泵相比,可节约3/5的检泵修井费.
