川东漏失层固井技术
CEMENTING TECHNIQUE OF LOST CIRCULATION FORMATION IN EASTERN SICHUAN
-
摘要: 四川川东气藏埋藏深、产气量大、地层压力系统复杂,裸眼中高低压力系统并存,钻井过程中井漏频繁。针对不同漏失性质,采取了不同的固井技术,提高了固井质量,满足了高压气田勘探开发的需要。Abstract: Gas-bearing reservoir in Eastern Sichuanthat buried deeply,has great gas production and complex formation pressure system.Because existing different pore pressure,lost circulation often take place during drilling.According to different lost situations,cementing technique were adopted to improve cementing quality and meet the requirement of high gas field development.
