一、背景介绍黄沙坨油田属于火山岩裂缝性稀油油气藏,1999年投入勘探开发,生产实践表明,油井套管压力过高或过低,对油层出液状况影响较大。本文以采油井液面恢复测试资料为基础,通过计算对比,提出了采油井的合理套管压力范围,并拟合了黄沙坨油田油井合理控制套管压力界限研究图版,通过对油井的套管压力和产量进行对比,
I. Background Huangsutuo oil field belongs to volcanic fractured dilute oil and gas reservoirs. Since 1999, it has been put into exploration and development. Production practice shows that the casing pressure of oil well is too high or too low, which has a great influence on the liquid condition of the oil layer. In this paper, based on the test data of oil level recovery, the reasonable casing pressure range of oil well is proposed through calculation and comparison, and the reasonable control casing pressure limit chart of oil well in Huangsha Tuo oilfield is fitted. Tube pressure and yield were compared,
