试油,试井,试采
这三个术语对初涉石油行业的人来说是很难懂得的,它们之间的接洽跟差别:
试油,Best CHI Straighteners,也就是地层测试(formation test),其主要目的是测试某个地层中的流体到底是油仍是水,因测试进程要放喷并测压,chi nano hair dryer,因此,试油的同时也能测试出地层的产能大小和压力温度的高下,best hair straighteners。测试过程中压力和产量的变更,cheap chi straighteners,也反应了地层物性的好坏及传染情形,因此,也能对地层的物性参数做出评估。试油可以在下套管前进行裸眼测 试,chi hair dryer,也能够在下套管落后行射孔测试,但都是在完井前进行的。试油的过程,实质上也是试井的过程,要用到很多渗 流力学的实践常识。由于要放喷,加之地面不分别装备和集输管线,Cheap CHI Flat Iron,为了节俭和环保,试油的时光通常极其短暂。
试井,也就是对油井进行的测试(well test),其主要目标是测试产层和油井参数,它个别是在生产井(包含灌水井)长进行的测试。试井分稳定试 井和不稳定试井,稳定试井(体系试井)主要是失掉油井的产能参数,不稳定试井重要是取得地层的流动参数和压 力以及表皮因子等参数。不稳固试井又分压力下降试井和压力恢复试井,因为大多数油井都处于出产状况,因而, 压力恢复试井占的比例也最大。
试采,实际上就是生产(production),即油田小规模或短时间的生产,普通是评价井或详探井(包括 预探井)的生产。试采的主要目的是懂得油井的生产动态和产量压力的递减情况。试采过程要进行一系列的试井测 试。
弥补:
1、试采工作是试油工作的连续,是衔接勘察和开发工作的主要环节。试采是应用探井或评价井,依据试油结果资 料,进一步意识储层,获得油气藏动态资料,控制油气藏开采特色,断定公道的稳定产能,提前配套开采相干技术 ,猜测生产规模和经济效益,为提交储量和编制油气田开发计划提供依据。
2、试采工程技术研讨内容和目的:在试采工艺、资料录取及资料解释方面做些工作,为区块范围开发 供给根据。
3、幻想的试采技巧是开式试采、可能实现井下关井、数据可以地面直读或远程传输,重点在于试井材料的有效剖 析说明。
