Description
Technical field
The present invention relates to a kind of method, belong to the oil exploration technology field monitoring lifting and lowering drill process at artesian well locale and automatic grouting control.
Background technology
At situ of drilling well, making a trip is a kind of very conventional operation, and occurs a lot of beyond thought emergency case in the round trip process probably, and especially well kick, leakage situation make a trip and take place very easily to bring out blowout behind the well kick, and the consequence that causes is very serious.
In trip-out process, trip out the drill string of some after, the pit shaft liquid level can drop to certain altitude, needs the pressure of the corresponding drilling fluid of perfusion with the balance stratum.At operation field, a general provision every 3-5 cylindrical drill bar or a cylindrical drill quickly just should be filled once, if untimely grouting, then pressure reduction can appear in head of liquid and the strata pressure that is descended by the pit shaft liquid level, this pressure reduction can not get balance and causes overflow easily, and then causes well kick, occurs blowout in the time of serious.The excessive velocities that trips out drill string in addition is easy to generate the pressure excitement, also well kick or leakage can occur.At present, domestic grouting when pulling out of hole, ordinary circumstance is the drilling rod that whenever trips out some, by the grouting of Artificial Control charge pump, this requires the driller must remember to trip out the quantity of drilling rod, also needs to switch the valve at standpipe place sometimes, and is very loaded down with trivial details.Under when boring, by the amount of returning that the driller observes bleed off pipe place drilling fluid, rely on artificial judgment whether well kick or leakage take place, inefficiency, the human factor influence is bigger.
Though present domestic some simple grouting control systems that have, function is very simple, adopts PLC or single-chip microcomputer to control, and by sensor and controller construction system, error is bigger, and on-the-spot Practical significance is little.Because the process complexity that makes a trip has a lot of uncertain factors, the analysis and judgement that causes state is the difficult point of control.
Summary of the invention
The purpose of this invention is to provide a kind of accuracy and reliability that situ of drilling well makes a trip and is in the milk that solve, improve on-the-spot operating efficiency, ensure the method to monitoring lifting and lowering drill process at artesian well locale and automatic grouting control of round trip process safety.
For realizing above purpose, technical scheme of the present invention provides a kind of method to monitoring lifting and lowering drill process at artesian well locale and automatic grouting control, it is characterized in that, utilize existing drilling well monitor, insert rate of discharge sensor, the pond sensor that makes a trip, CAN I/O control device by the CAN bus node, utilize this method to detect in real time and analyze, provide analysis result, and charge pump is carried out automatic grouting control, its method is:
The first step. in the grouting jar, the pond sensor that makes a trip is installed;
Second step. installation outlet flow transmitter in bleed off pipe;
The 3rd step. utilize the first analog quantity CAN bus node to connect the pond sensor that makes a trip;
The 4th step. utilize the second analog quantity CAN bus node to connect the rate of discharge sensor;
The 5th step. utilize CAN I/O node to connect the opening of charge pump, guard's valve;
The 6th step. each CAN node is linked together by cable, and an end of CAN cable is connected on the drilling well monitor;
The 7th step. program with the C language, operate in the drilling well monitor;
The 8th step. utilize drilling well monitor and CAN I/O node join operation, comprehensive detection obtains:
A. the reduction of grouting jar interior pond volume is similar to the drilling well liquid measure of perfusion when pulling out of hole, i.e. grouting amount compares the grouting amount, if the grouting amount greater than need grouting amount, illustrates in the pit shaft leakage to occur with needing the grouting amount; If less than need grouting amount, overflow or well kick might appear in explanation; If equaling needs the grouting amount, illustrate normal;
B. generally speaking, because effect of inertia, super drilling fluid of irritating can flow out the drilling fluid of respective volume by bleed off pipe in the pit shaft, this situation can be by the drilling well liquid measure of rate of discharge sensor measurement bleed off pipe outflow, promptly return the slurry amount, if with the grouting amount, return the slurry amount with needing the grouting amount to compare, if greater than need grouting amount, overflow or well kick might appear in explanation; If, leakage might occur less than need grouting amount; If equate, illustrate normal.By installation make a trip pond and rate of discharge sensor, above-mentioned condition is detected and analyzes, in conjunction with the powerful state arbitration functions of drilling instrument itself, judge trip-out condition and grouting condition again, charge pump is poured into control.
The present invention utilizes original drilling well monitor, adopts the distributed frame of CAN bussing technique to connect explosion-proof analog quantity CAN bus node and rate of discharge sensor, the pond sensor that makes a trip, CAN bus I/O node, drilling well monitor.CAN bus control unit unit is by explosion-proof CAN bus I/O node, CAN bus sensors unit and drilling well monitor constitute, the control centre of whole system is the drilling well monitor, utilize drilling well monitor and CAN I/O node join operation, comprehensive detection, obtain the trip-out condition, the analysis result of grouting condition, and according to analysis result charge pump is carried out automatic grouting and control, and according to return the slurry result carry out integrated interpretation, draw correct abnormality evaluation result, various control algolithms all realize by software, make full use of original drilling instrument hardware platform, need not other hardware carrier.
Automatic grouting need be in the milk according to user's requirement when pulling out of hole, and the judgement of trip-out state relates to the detection of well depth system and tong systems, and this is a difficult point for grouting system.The drilling instrument that utilization of the present invention is used has at the scene in a large number been avoided this problem, and the state that utilizes drilling instrument itself to provide is judged the judgement of the trip-out state that has solved grouting, has solved this problem by the communication interface agreement on the software.
Advantage of the present invention is:
1. owing to utilized original drilling instrument, make system architecture very simple, and obtained a lot of state judgements easily, improved the accuracy of system greatly;
2. adopt intelligent CAN I/O module to control, alleviated the task of drilling well monitor CPU, real-time;
3. this method greatly facilitates on-the-spot use owing to adopted the CAN bussing technique, has improved the reliability of system.
