Description
Technical field
The utility model relates to the system of a kind of early monitoring for gas drilling downhole safety, comprehensively analysis and real-time early warning in well drilling monitoring technology field, particularly relating to a kind of formation water outlet early monitoring, returning out with boring the gas drilling pre-warning system for monitoring that landwaste is monitored, well head returns out gas component monitoring.
Background technology
Abroad from the phase at the beginning of the fifties in last century, apply air drilling carries out field drilling.After this, this technology is widely used in the probing of Oil/gas Well (comprising coal bed gas) all over the world and develops.Apply this technology although domestic more late, have also been obtained extensive popularization, particularly in areas such as the triumph accurate Ge Er basin of western small towns, the Sichuan Basin and Song-liao basin.In order to the process of expediting exploration exploitation, the ratio that gas drilling is applied to prospect pit and risk prospect pit increases year by year, but because geology is uncertain, detection analysis and early warning means are limited and lack the reasons such as reasonable processing method, security incident happens occasionally to cause down-hole complexity in wellbore construction process, bit freezing, fire etc., cause very large loss to engineering construction, seriously constrain gas drilling construction progress and application prospect.
External for problems such as gas drilling down-hole blastings; have developed mechanical underground truce instrument; truce instrument closing organ insurance (kirsite) fusing will be arranged on drilling tool when catching fire can be fired in down-hole, thus close gas injection passage, reach the object of fire extinguishing and protection drilling tool.The advantage of this instrument is that structure is simple, dependable performance, and shortcoming, for cannot automatically recovering after each closedown, needs to pull out of hole and changes, greatly affect normal construction process.In formation water output, the T.R.Reinhart of Shell Co. Ltd proposes by being arranged in the sediment outflow pipeline of ground insulate electrode in porcelain plate and the tubular electrode in a pair of sediment outflow in SPE article, thus can measure, monitor the dielectric constant of gas and the debris flow returned out in the sediment outflow pipeline of ground, stratum whether water outlet accurately can be found by the change of dielectric constant, determine water layer bit depth, the method of monitoring water yield situation of change, and carried out tens mouthfuls of well field trials; Domesticly also obtain certain progress in this respect, patent CN 101029564A provides the continuous detecting method of a kind of gas drilling down-hole state, can on-line checkingi CO

2s, hydrocarbon gas concentration and return out the humidity etc. of gas; The people such as Ma Xiaowei propose and install scouring force sensor on sediment outflow pipelines in " gas drilling returns out landwaste the study of the monitoring method ", the method containing sand gas, the change of sediment outflow pipeline inwall scouring force being judged to down-hole sand return situation is returned by monitoring annular space, but the method belongs to intrusive mood to be measured, and is huge test to sensor life-time; The monitoring such as injecting gas flow, casing pressure, vertical pressure, stratum produced fluid flow for gas drilling have not been reported.
In sum, although this in obtain certain progress both at home and abroad, but still there is following problem demanding prompt solution: do not have formation water outlet early process to further investigate; Fall behind with boring the intrusive mood measuring technique returning out landwaste, the life-span is shorter, cannot obtain the parameter such as mass flow, concentration and carry out quantitative analysis; Return out gas component accuracy of detection, response speed not high; Existing drilling engineering parameter measuring system cannot adapt to gas drilling feature; Do not form the integrated gas drilling well downhole safety technology considering formation water output, concentration of cuttings, engineering parameter and gas component.
Summary of the invention
