科威特大部分原油都是从自喷井中开采出来的,这些井已经开采了大约25～35年了。这些井的套管,油管和固井材料一直保护得很好。由于套管柱外部地层水的窜槽,科威特石油公司的石油开采业和工程技术部门面临的一个主要问题,就是控制套管内部的不断腐蚀。这是因为实际上并不是所有的井都已做了阴极防腐。在许多情况下有相当多井的套管外侧有很少的水泥固井或者根本没有水泥固井。因此,很多套管已经从外部被损坏,并且壁厚已经开始有一定程度的变薄,在套管的一些薄弱部分已经出现了孔洞。这篇资料讨论的主要议题是液体在套管内部和外部流动时,测量套管各部分的地温变化,以便能够指出孔洞的位置,提出防腐及固井等修井措施,并为地面工程设计提供温度、压力参数。文中阐明了测量地温的基本原理和计算方法。并通过实例和实测的地温曲线数据为这一方法提供了有力依据。 Much of Kuwait’s crude oil is mined from self-spraying wells that have been mined for about 25 to 35 years. Casing, tubing and cementing materials for these wells have been well protected. As a result of the channeling of formation water outside the casing string, one of the major problems facing KOC’s oil extraction and engineering departments is the control of constant corrosion inside the casing. This is because in fact not all wells have been cathodically protected. In many cases there is little or no cement cementing on the outside of the casing with a considerable number of wells. As a result, many of the sleeves have been damaged from the outside and the wall thickness has begun to be somewhat thinned, and holes have appeared in some of the weak portions of the sleeve. The main topic discussed in this paper is the measurement of changes in the ground temperature of various parts of the casing as the liquid flows inside and outside the casing so as to be able to indicate the location of the hole and to propose workover measures such as corrosion protection and cementing and to provide the groundwork design Temperature, pressure parameters. In this paper, the basic principle and calculation method of measuring ground temperature are explained. And by the example and the measured geothermic curve data provide a strong basis for this method.
