Description
Technical field
The present invention relates to bore hole annulus gas cut real time monitoring field in petroleum and natural gas drilling process, specifically,
It is related to the pressure pulse produced when downhole data is transmitted using measurement while drilling instrument in a kind of drilling process to fluctuate signal come real
When monitoring annular space gas cut method.Bore hole annulus are invaded for real-time monitoring early detection formation gas, is to take well control in time
The more sufficient time is won in measure.
Background technology
Gas cut is that in drilling process, when chance high pressure formation is bored, the effective head of liquid in shaft bottom is caused less than strata pressure
Natural gas in stratum invades the phenomenon of bore hole annulus drilling fluid；At the beginning of there is gas very strong compressibility, gas to invade well
Phase, because by the larger head of liquid in top, gas is in compressive state, gas volume very little, it is difficult to find gas cut.With
The circulation of drilling fluid, gas rises along bore hole annulus, and top head of liquid is gradually reduced suffered by gas, and volume constantly expands increasing
Greatly.Gas expands more severe closer to well head, and annular space head of liquid reduces faster, more easily causes gas blowout accident to occur.
Therefore, need whether real-time monitoring is carried out to gas cut in drilling operation course, it is found that more early well control risk is smaller.
Existing gas cut monitoring method mainly include mud pit level monitoring technology, well head flowmeter method, annular pressure with
Bore monitoring method and sound wave monitoring method etc..First two method is set up based on volume expansion, simple and practical, but
Be in high temperature high pressure deep well, ultra-deep well drilling and drilling well under some complicated geological conditions, find gas cut time have compared with
Big hysteresis quality.Annular pressure monitoring while drilling method can timely and effectively find gas cut, but auxiliary facility requirement is high, and cost is held high
It is expensive.Sound wave monitoring gas cut technology is a kind of early stage gas cut monitoring method that drilling well research institute of the former Soviet Union proposes.Then permitted both at home and abroad
Multi-expert scholar and company have also carried out the research of this respect in succession, but affected by various factors, fail effectively to solve phase always
Technical bottleneck is closed, does not also have popularization and application so far.
Pressure wave early monitoring gas cut technology mainly uses spread speed of the pressure wave in pure drilling fluid to be much larger than
The principle of the spread speed in gas cut drilling fluid, can when gas cut is also smaller also in well middle and lower part, gas cut amount just by
Monitor.Under conditions of annular space does not occur gas cut, spread speed of the pressure wave with annular space in drill string is essentially identical；In gas
After body is invaded in mineshaft annulus, spread speed of the pressure wave in annular space gas cut drilling fluid is obviously reduced, and is not received in drill string
Spread speed in gas cut drilling fluid is constant, so pressure wave travels to well head along drill string from shaft bottom with the paths of annular space two
Time has certain difference, it is possible to use pressure wave is in drill string and annular space is delivered to time difference on ground to monitor mineshaft annulus
Whether gas cut there is.Existing way be by the use of positioned at ground drilling fluid pump produce pressure wave as pressure wave source, its ripple
Dynamic variation characteristic is not obvious, and the method operation of pressure wave characteristic is changed and excessively complicated by adjusting pump speed or discharge capacity；And this hair
It is bright to transmit underground using the measurement while drilling instrument (MeasurementWhile Drilling, MWD) for being installed on nearly bit location
Used as pressure wave source, the pressure wave signal feature that it is produced substantially, is easy to ground to the pressure pulse fluctuation signal produced during data
Analysis system carries out effective differentiation treatment.In nearly drill bit in current directed drilling operation and part straight well drilling operation course
MWD is installed with measurement while drilling well track parameter in position, based on the present invention, it is only necessary to increases wellhead assembly and is capable of achieving annular space gas
Invade real-time monitoring；Its technological operation is simple, with low cost, it is easy to install, and rationally, reliability is high, is easy to popularization to make for scientific in principle
With.
The content of the invention
It is an object of the invention to the shortcoming for overcoming prior art to exist, seek to design a kind of oil/gas drilling bore hole annulus gas
Invade monitoring method, early detection gas cut takes counter-measure in time, it is to avoid property and personal casualty loss, for safety drilling is provided can
By ensureing.
To achieve these goals, gas cut monitoring method of the present invention is supervised using measurement while drilling instrument and wellhead ground
Device is surveyed to implement.The wellhead ground device mainly include annular pressure sensor, standpipe pressure sensor, filter processor,
Small signals amplification device, data processing and real-time monitoring system and alarm.The present invention is using the MWD hairs for being installed on nearly bit location
The pressure wave signal penetrated travels to well head by drill string and the paths of annular space two, is passed using the standpipe pressure being installed near well head
Sensor and casing pressure sensor are received from the pressure wave signal in drilling rod with annular space, using filter processor filter ring respectively
The pressure wave signal that pneumatics force snesor and standpipe pressure sensor are received, using small signals amplification device to filtering after weak letter
Number treatment is amplified, finally calculate pressure wave using data processing and real-time monitoring system travels to well head two from two paths
The time difference of individual sensor, if calculating annular pressure sensor by real-time monitoring system and standpipe pressure sensor is received
The pressure wave signal that shaft bottom MWD launches does not have time enough poor, shows that bore hole annulus do not occur gas cut or gas cut is not tight
Weight, then alarm does not send early warning or alarm signal；If real-time monitoring system calculates annular pressure sensor and standpipe pressure
Sensor receives the pressure wave signal existence time difference that shaft bottom MWD launches and reaches warning value set in advance, shows well
Eye thimble sky has occurred than more serious gas cut, then alarm sends early warning or alarm signal, and points out Field Force to take well control
Measure, until annular pressure sensor and standpipe pressure sensor receive the time of the pressure wave signal that shaft bottom MWD launches
Difference is less than warning value.
Underground signal transmitter of the present invention is the MWD that signal is transmitted using pressure pulse.
The apparatus main body structure bag of the pressure wave signal real-time monitoring gas cut of utilization measurement while drilling instrument of the present invention
Include：Pressure wave signal generator MWD, annular pressure sensor, standpipe pressure sensor, filter processor, small signals amplification device,
Data processing and real-time monitoring system, alarm etc..
Compared with existing gas cut monitoring technology and device, the invention has the characteristics that：
1. underground signal transmitter is the MWD that signal is transmitted using pressure pulse, because all of directional well and part are straight
Well can all install MWD, so in the present invention, it is only necessary to increase wellhead assembly and be capable of achieving annular space gas cut real-time monitoring, its technique
Simple to operate, with low cost, it is easy to install, rationally, reliability is high, is easy to promote the use of for scientific in principle.
The pressure wave signal feature that 2.MWD is produced substantially, is easy to identification, and monitoring accuracy is high, and real-time is extremely strong, operation specialty
Property require it is low, stability preferably, measurement process utilizes computer monitoring, therefore high degree of automation.
3. when realizing that bore hole annulus occur gas cut, just can accurately discriminate whether that formation gas are invaded in gas cut early stage
Enter, give warning in advance.
