摘要:
为了保证环空带压气井生产阶段的井筒完整性,确定气井环空压力安全运行范围,建立了基于API RP 90-2推荐做法的环空带压安全评价方法,重点研究了气井环空带压临界控制值计算方法,提出了1套方便现场应用的环空压力管控图版,针对某环空带压气井进行了现场应用研究。研究表明:API RP 90是针对海上油气井环空带压安全评价的推荐做法,在API RP 90-2推荐做法发布以后已不再继续适用于陆上油气井;基于API RP 90-2的推荐做法考虑因素更为全面,推荐在陆上油气井使用;环空带压临界控制值不再是1个固定值,而是随服役时间增长以及相邻和自身环空压力变化等因素不断变化的值。
Abstract:
To ensure the wellbore integrity of gas well with sustained annular pressure (SAP) during the production phase and determine the safe operating range of SAP, a safety evaluation method of SAP based on API RP 90-2 recommended practice was established. The calculation method on the critical control value of SAP for gas well was mainly studied, and a set of SAP management chart for field application was put forward. Finally, the field application study of a gas well with SAP was carried out. The results showed that API RP 90 was recommended for the safety evaluation of offshore oil and gas wells with SAP, but it was no longer suitable for onshore oil and gas wells after API RP 90-2 was published. The consideration of API RP 90-2 was more comprehensive and it was recommended for onshore oil and gas wells. The critical control value of SAP was no longer a fixed value but a value constantly varying with a number of factors such as the increase of service time and the change of adjacent and self-annulus pressure.
