摘　　要：在油气勘探开发现场,目前地层中氦气检测主要依靠气测录井技术,但在钻井液经环空返至地面的过程中,随着温度、压力等环境条件的改变,氦气等不易溶于钻井液的气体随着钻井液上升到地面后,会通过液面直接逸失到大气中。同时,现用的电动脱气装置安装位置距离钻井液出口较远,无法收集钻井液出口管道内逃逸的氦气,从而影响了氦气检测的可靠性。为此,设计研发了防逃逸式氦气收集装置,该装置由集气室、浮筒、固定装置、防逃逸补气管、集气管、提手等组成,固定在钻井液槽中钻井液管道的出口位置,其防逃逸补气管直接与钻井液出口管道连接,可以将钻井液中逸出的氦气补充至集气室内,从而便于及时收集钻井液中气体,减少氦气逃逸,有效提高氦气检测的可靠性。该装置结构简单,加工成本较低,使用便捷,适用于石油勘探现场对出口钻井液中氦气的收集,方便及时获取钻井液中氦气含量,提高了氦气气藏勘探的可靠性和有效性。In the oil&gas exploration and development field,the detection of helium in the strata mainly relies on gas logging technology.However,during the process of drilling fluid returning to the ground through the annulus,gases such as helium that are not easily soluble in drilling fluid,will rise to the ground along with the drilling fluid and escape directly into the atmosphere through the liquid surface as the temperature,pressure and other environmental conditions change.At the same time,the existing electric degassing device is installed far away from the drilling fluid outlet,which cannot collect the helium escaping from the drilling fluid outlet pipe,thus affecting the reliability of helium detection.To this end,an antiescape helium collecting device is designed and developed,which consists of a gas collecting chamber,floating buoys,a fixing device,an antiescape gas replenishment pipe,a gas collecting pipe,a handle,etc.It is fixed at the outlet position of the drilling fluid line in the drilling fluid ditch.Its antiescape gas replenishment pipe is directly connected with the drilling fluid outlet pipe,which can replenish the helium escaping from the drilling fluid to the gas collecting chamber,thereby being convenient to collect the gas in the drilling fluid in time,reduce the helium escaping,and effectively improve the reliability of helium detection.The device has the advantages of simple structure,low processing cost and convenient use.It is suitable for collecting helium in the outlet drilling fluid at the petroleum exploration sites,convenient for timely acquisition of helium content in drilling fluid,and improves the reliability and effectiveness of helium gas reservoir exploration.
