Abstract
The utility model discloses an automatic monitoring system for drilling mud, formed by connecting a central processor module comprising a computer and MCGS with a signal sensor of a data-collecting module, a flow transmitter, a control system module, an inquiry and print module, an alarm device, a drilling stand display screen and a display screen of a mud watchroom through a lead, and then by connecting the flow transmitter and the control system module with a grouting pump through a lead. The utility model integrates the functions of automatic measuring, mud total and variation computing, automatic mud grouting, intelligent underground situation judging and judged result displaying and has the advantages of simple operation, reliable performance, accurate test result and high degree of automation.
Description
Affiliated technical field
The utility model relates to a kind of oil drilling mud monitoring system, the drilling mud automatic monitored control system of the particularly a kind of DCS of employing technology monitoring mud situation of change from the whole drilling process of the completion of spudding in, be applicable to the automatic monitoring of mud dynamic change in the oilfield drilling, to reduce the accident in the drilling well oilfield drilling.
Background technology
At present, in oil, gas drilling process (drilling process is divided into trip-out, following brill, empty well, creeps into four kinds of operating modes), the accident that well kick, leakage take place in the down-hole all can reflect by the situation of change of mud, technique known is, regularly measure the depth of mud of each slurry tank by operating personnel, and calculate mud amount, whether abnormal conditions take place to judge the down-hole.Simultaneously, operating personnel also need in time to start grout pump according to current working and become full state to keep the mud in the pit shaft.
Summary of the invention
In order to overcome prior art complex operation, certainty of measurement is low, judged result is coarse shortcoming, the utility model provides a kind of drilling mud automatic monitored control system, not only collection is automatically measured, computation of mud total amount and variable quantity, automatic filling mud, intelligent decision down-hole situation and show that the judged result function is an one, and has easy and simple to handle, reliable operation, testing result is accurate, automaticity is high advantage.
The technical scheme that its technical problem that solves the utility model adopts is: the CPU module that computer and MCGS configuration software are formed, be connected with signal transducer, flow transmitter, control system module, inquiry and print module, alarm, rig floor display screen, the mud room on duty display screen of data acquisition module respectively by lead, flow transmitter, control system module are connected with grout pump by lead again and constitute.During use, there is the pit shaft of drill string to be communicated with by pipeline with following, connects power supply to the utility model simultaneously, promptly can devote oneself to work, one side is handled from the signal that is installed in the sensor acquisition on each slurry tank, result is presented at be positioned on rig floor display screen and the mud room on duty display screen; Start grout pump according to the current working command and control system on the other hand and in pit shaft, pour into mud.The grouting data also are recorded and are presented on the display screen.Whether simultaneous computer is analyzed the result of above two aspects, make the down-hole situation and judge normally, and show judged result.When finding well kick, leakage accident, alarm sends alarm signal.
The beneficial effects of the utility model are to monitor mud dynamic change situation in the oilfield drilling automatically, to reduce the accident in the oilfield drilling, the reduction drilling cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a concrete structure schematic diagram of the present utility model.
Accompanying drawing number is: 1, signal transducer, 2, data acquisition module, 3, inquiry and print module, 4, alarm, 5, CPU module, 6, rig floor display, 7, mud room on duty display screen, 8, the control system module, 9, flow transmitter, 10, grout pump, 11, pit shaft, 12, drill string.
The specific embodiment
Referring to Fig. 1, the CPU module (5) that computer and MCGS configuration software are formed, be connected with signal transducer (1), flow transmitter (9), control system module (8), inquiry and print module (3), alarm (4), rig floor display screen (6), the mud room on duty display screen (7) of data acquisition module (2) respectively by lead, flow transmitter (9), control system module (8) are connected with grout pump (10) by lead again and constitute.During use, there is the pit shaft (11) of drill string (12) to be communicated with by pipeline with following, with 4～8 signal transducers (adopting liquid level sensor, pressure sensor, fluid sensor), liquid level sensor is installed on the slurry tank that needs to monitor, pressure sensor is installed in drilling crew's weight indicator hydraulic circuit, fluid sensor is installed on drilling crew's mud outlet elevated trough, connect power supply to the utility model simultaneously, promptly can devote oneself to work, all signals that collect enter data collecting system and send central processing unit in the lump, for the central processing unit analyzing and processing.Rig floor display screen (6), mud room on duty display screen (7) are installed in respectively in rig floor and the mud room on duty.Control cabinet is installed near driller's workbench.The operator only need press the button of current working correspondence during operation, and system can be by the program of setting, and with mud amount, the mud total amount of current each slurry tank, the variable quantity of a certain period and the circulation of work at present situation are presented on the display screen.One side is handled the signal from various sensor acquisition, result is presented at be positioned on rig floor display screen (6) and the mud room on duty display screen (7); Mud parameter variation with working condition and slurry tank shows on the other hand.When grout pump (10) started, its flow size and startup, dwell time all can be delivered to central processing unit.Central processing unit can carry out analysis-by-synthesis to all parameters, and unusual if some parameter occurs, system is with display alarm information.The all working parameter all is kept in the database, can inquire about at any time and print by inquiry and print module (3).Start grout pump (10) according to the current working command and control system and in pit shaft, pour into mud.The grouting data also are recorded and are presented on the display screen.Whether simultaneous computer is analyzed the result of above two aspects, make the down-hole situation and judge normally, and show judged result.When finding well kick, leakage accident, alarm (4) sends alarm signal.
