具体实施方式 Detailed ways

:下面结合附图对本实用新型作进一步说明:由图1所示,该充气钻井气液混合控制装置,包括主管线1、气体主管线13及基液主管线6,基液主管线6连接在基液应急管线21上的三通4上,基液主管线6上依次连接有闸阀5、流量计7及单流阀8,基液主管线6的尾端与喷嘴总成12连接,基液应急管线21上连接有闸阀3、放气阀20及三通2,气体主管线13上依次连接有流量计14、单流阀15及压力表16,气体主管线13的尾端分别连接有气体应急管线18及混合管线11,气体应急管线18上依次连接有球阀17及单流阀19,混合管线11上依次连接有喷嘴总成12、压力表9及闸阀10,混合管线11的尾端连接在三通2上,三通2的另一端连接主管线1,气体应急管线18的尾端连接在主管线1上。 : DRAWINGS The present invention is further described as: FIG. 1, the pneumatic control drilling liquid mixing apparatus 1 comprises a main line, the main line 13 and the gas liquid yl main line 6, the base fluid in the main line 6 is connected tee on the emergency line 21 a base liquid 4, the base fluid in turn connected to the main line valve 5 has 6, 7 and a single flow meter valve 8, and the trailing end of the base liquid main line 12 connected to the nozzle assembly 6, the base fluid the emergency line 21 is connected with a valve 3, a three-way purge valve 20 and 2, the gas main pipeline 14 in turn is connected to a flow meter 13, a single flow valve 15 and pressure gauge 16, the trailing end of the gas main line 13 are connected to gas emergency line 18 and mixed in line 11, in turn connected to a single ball valve 17 and valve 19, in turn connected to the line 11 the mixed gas emergency line 18 on the nozzle assembly 12, valve 10 and pressure gauge 9, line 11 is connected to the trailing end of the mixing 2 in the three-way, 2-way and the other end is connected to the main line 1, the emergency tail gas line 18 is connected to the main line 1.

在实际使用过程中,该充气钻井气液混合控制装置,打开闸阀(5,10),关闭闸阀3、球阀(17,20),基液首先通过基液主管线6进入到喷嘴总成12,气体同时从气体主管线13进入到喷嘴总成12,基液和气体在喷嘴总成12内均匀混合成充气钻井液,之后,充气钻井液进入到气液混合管线11内,再进入主管线1内,充气钻井液从主管线1进入到井内。 In actual use, control the pneumatic drilling liquid mixing means, a gate valve (5,10), the gate valve 3 closed, the ball valve (17, 20), the base liquid enters the first main pipe 6 through the base liquid to the nozzle assembly 12, at the same time the gas from the gas into the main line 13 to the nozzle assembly 12, the base liquid and a gas inflator 12 are uniformly mixed into the drilling fluid in the nozzle assembly, then, the drilling fluid into the inflatable gas-liquid mixture line 11, then into the main line 1 the inflator into the drilling fluid into the well 1 from the main line. 由于在基液主管线6和气体主管线13上分别安装有流量计(7,14)和单流阀(8,15),这样,基液和气体的流量就可以通过流量计(7,14)进行监控,又由于单流阀(8,15)分别安装在流量计(7,14)的下游,使得流量计(7,14)的测量更加准确。 Since the base liquid and the gas main line 6 are attached to the main line flow meter (7,14) and a single valve (8,15) 13, so that the flow of base liquid and the gas through the meter can (7, 14 ) monitor, and since the single valve (8, 15) are mounted downstream of the flowmeter (7, 14) such that the measured flow meter (7, 14) is more accurate. 当钻井需要接单根的时候,可先停注基液,待气体注入到井口第一个钻具回压阀以下时停注,这时,可将放气阀20打开,将气体放掉,实现钻井的安全接单根;接单根时,也可以先停注气体,待基液注入到井口单流阀以下时停注基液,实现自动安全接单根。 When drilling need to take a single time, may stop the injection group first fluid to be injected into the gas wellhead drilling a first back-pressure valve when stopping the injection, this time, the discharge valve 20 can be opened to let go of the gas, drilling implement security single access; when single connection, the gas injection may be first stopped, to be injected into the base fluid injection group was stopped when the wellhead valve to a single, automatic single safety ground. 另外,当控制装置出现故障时,可关闭闸阀(5,10)、放气阀20,打开闸阀3、球阀17;这样,气体就通过气体主管线13进入到气体应急管线18进到主管线1内,基液从基液应急管线21直接进入到主管线1与气体混合,从主管线1的出口进入到井内,从而形成了短路循环,达到了应急的目的。 Further, when the control device fails, the gate valve (5,10), the purge valve 20, valve 3 is opened, the ball valve 17; thus, the gas proceeds to the emergency gas through the gas line into the main line 13 18 main line 1 the base fluid from the base fluid line 21 directly into the emergency main line 1 and the mixing gas from the outlet into the main line 1 into the well, thereby forming a short-circuit circulation, emergency purpose. 该控制装置可将基液和气体充分混合,确保钻井液的密度相对稳定,满足充气钻井工艺上的要求。 The control means may be sufficiently mixing a base fluid and gas, drilling fluid density to ensure a relatively stable, meet the requirements of the pneumatic drilling process.
