Description
Technical Field
The present invention relates to the field of data processing technologies, and in particular, to a drilling risk alarm method, device, system, and storage medium.
Background
As hydrocarbon exploration developments shift toward complex formations, well control risks of drilling and the risk of ingestion of harmful gases become more pronounced. For well control risks such as kick, if the risk cannot be found in time in the drilling process, severe accidents such as kick and the like are easy to cause. Moreover, the earlier well control risks such as overflow are found, the easier the well control risks are to handle, accidents can be avoided, and more importantly, the damage of blowout and well control operation to an underground oil and gas layer can be reduced. For harmful gases, such as highly toxic gas hydrogen sulfide gas, the drilling of sulfur-containing formations must closely detect the content of hydrogen sulfide in drilling fluid and give an alarm in time, otherwise, the physical health of on-site operators and surrounding masses is easily compromised.
At present, the well kick, well leakage and other risk detection technologies are very mature, for example, the content of hydrogen sulfide can realize high-precision multipoint detection, and the early risk prediction capability of drilling is greatly improved. However, the risk alarm technology still uses face-to-face reporting, telephone reporting, step-by-step reporting and other modes, and is difficult to notify the command department in time.

Detailed Description
In order that those skilled in the art will better understand the present invention, a technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example 1
Fig. 1 is a flowchart of a drilling risk alarm method according to an embodiment of the present invention, where the method may be performed by a drilling risk alarm device, the device may be implemented in hardware and/or software, and the device may be configured in an electronic device. As shown in fig. 1, the method includes:
and S110, if the risk detection triggering event is detected, acquiring at least one group of risk judgment data according to a preset data acquisition period through the comprehensive logging system.
The present solution may be performed by a risk alert system in communication with the integrated logging system. The integrated logging system may include one or more well information gathering devices, such as level sensors, flow sensors, gas sensors, and the like, for gathering well gas-liquid related measurement data. The risk alarm system can judge whether risk detection is needed or not by detecting a risk detection trigger event. The risk detection triggering event can be that a user manually starts risk detection, can reach preset risk detection time, can also be that a risk alarm system detects that a risk detection post is unattended, and automatically starts risk detection. The risk alarm system can acquire risk judgment data through the comprehensive logging system in a certain data acquisition period. The risk judging data can comprise drilling fluid inlet flow, drilling fluid outlet flow, harmful gas concentration and the like.
And S120, if the risk judgment data meets the preset judgment conditions, controlling the target alarm to alarm.
It will be readily appreciated that the risk alarm system may include one or more alarms that may be used to alarm a risk event. In order to facilitate distinguishing alarm of different types of risk events, the risk alarm system can distinguish different risk events by setting one alarm differently, for example, the risk alarm system can perform voice alarm on type A risk events with frequency A and perform voice alarm on type B risk events with frequency B. The risk alarm system can also alarm the risk event by arranging a plurality of alarms respectively, for example, an alarm A alarms the A type risk event in an audible and visual way, and an alarm B alarms the B type risk event in an audible and visual way.
The risk alarm system can determine the type of the risk event existing in the well by comparing the risk judging data with judging conditions. Wherein the risk event type may include overflow risk, harmful gas excess risk, and the like. Specifically, the risk alarm system can judge the risk event existing in the well drilling according to the comparison result of the risk judgment data related to the target risk event type and the risk alarm threshold value. For example, determining whether there is an excess of hydrogen sulfide gas in the wellbore based on a comparison of the hydrogen sulfide gas concentration to a hydrogen sulfide concentration threshold.
In this scheme, optionally, the risk alarm system further includes an alarm trigger device;
after detecting the risk detection trigger event, the method further comprises:
and if the triggering of the alarm triggering device is detected, controlling the target alarm to alarm through the risk alarm system according to the triggered alarm triggering device.
It can be appreciated that the hydrocarbon exploration process has various formation environments, and in some complex drilling environments, the risk judgment needs to be performed by relying on the experience of professionals. Accordingly, the risk alarm system may be configured with alarm triggering means for manual alarm. When the risk alarm system detects that the alarm trigger device is triggered, the professional personnel are stated to judge that the drilling risk exists, and the corresponding alarm is required to be controlled to alarm, so that powerful measures are taken for avoiding the risk in time.
The scheme supports manual triggering alarm, and ensures the reliability of the risk alarm system in the risk alarm.
In one possible solution, after controlling the target alarm to alarm by the risk alarm system, the method further comprises:
and generating alarm notification information according to the pre-acquired drilling information, the risk judgment data and the alarm record of the target alarm, and recording the alarm notification information to a database of the comprehensive logging system.
After the risk alarm system controls the target alarm to alarm, alarm notification information can be generated according to the drilling information, the risk judgment data and the alarm record of the target alarm. The drilling information can comprise drilling numbers, operation team numbers, drilling progress and the like. The alarm records may include risk event types, alarm reasons, etc. In order to more intuitively explain the alarm condition, the risk alarm system can represent alarm notification information in the forms of images, curves and the like so as to enable an upper command department to timely find out abnormality and adjust the exploration strategy. The risk alarm system can save the generated alarm notification information to a comprehensive logging system database so as to be uploaded to an associated department along with logging data.
The scheme records the generated alarm notification information to the database of the comprehensive logging system, is favorable for timely notifying drilling risks to related departments, and further realizes effective evidence recording and responsibility division.
According to the technical scheme, when a risk detection trigger event is detected, at least one group of risk judgment data is acquired through the comprehensive logging system according to a preset data acquisition period, and if the risk judgment data meets preset judgment conditions, a target alarm is controlled to alarm through a risk alarm system. The scheme solves the problem of poor drilling risk alarm timeliness, can maximally reduce drilling risk while avoiding alarm delay, and ensures exploration benefits.
Example two
Fig. 2 is a flowchart of a drilling risk alarm method according to a second embodiment of the present invention, which is refined based on the foregoing embodiment. As shown in fig. 2, the method includes:
s210, if a risk detection trigger event is detected, acquiring at least one group of risk judgment data according to a preset data acquisition period through the comprehensive logging system; wherein the risk judgment data comprises relative flow rate of drilling fluid outlet and concentration of harmful gas.
In the scheme, the relative flow of the drilling fluid outlet can be obtained through an ultrasonic liquid level sensor in the comprehensive logging system. The ultrasonic liquid level sensor can be arranged in the buffer tank of the cuboid outlet, and after calibration, the drilling fluid accounts for the percentage of the depth of the buffer tank. When drilling and circulating, under the condition that the inlet flow is stable, the outlet relative flow should be relatively stable or have small fluctuation in a certain range.
S220, if the relative flow of the drilling fluid outlet in the current data acquisition period is higher than that in the previous data acquisition period, acquiring the total pool volume change of the drilling fluid.
If the relative flow rate of the drilling fluid outlet of the current data acquisition cycle is higher than that of the previous data acquisition cycle, then there may be an overflow risk. The risk alarm system can be further judged by combining the total pool volume change of the drilling fluid.
And S230, if the total pool volume change of the drilling fluid is greater than a preset first overflow alarm threshold, controlling an overflow alarm to alarm.
If the total pool volume change of the drilling fluid is larger than a preset first overflow alarm threshold, the risk alarm system can control the overflow alarm to carry out audible and visual alarm. The first overflow alarm threshold may be a volume threshold, for example 1m 3 . The risk alarm system can control the overflow alarm to flash light with specific color according to a certain frequency according to the risk event. Meanwhile, the risk alarm system can also acquire drilling information through the comprehensive logging system, and generates alarm voice according to the risk event and the drilling information, so as to control the overflow alarm to alarm according to the alarm voice. For example, the overflow alarm may broadcast while flashing yellow light at a frequency of 60 beats per minute: note that there is a risk of overflow at well No. 1, 50 meters.
And S240, if the concentration of the harmful gas is greater than a preset concentration threshold, controlling the harmful gas alarm to alarm.
And if the concentration of the harmful gas is greater than a preset concentration threshold value, the risk alarm system can control the harmful gas alarm to carry out audible and visual alarm. In order to distinguish from overflow risk alarm, the risk alarm system can control the harmful gas alarm and the overflow alarm to alarm by adopting different sound and light. The harmful gas alarm can flash red light at a frequency of 120 times per minute and broadcast: "please note that there is a risk of hydrogen sulfide concentration excess at well number 1, 100 meters.
According to the technical scheme, when a risk detection trigger event is detected, at least one group of risk judgment data is acquired through the comprehensive logging system according to a preset data acquisition period, and if the risk judgment data meets preset judgment conditions, a target alarm is controlled to alarm through a risk alarm system. The scheme solves the problem of poor drilling risk alarm timeliness, can maximally reduce drilling risk while avoiding alarm delay, and ensures exploration benefits.

In this scheme, the drilling fluid inlet flow rate may be calculated by the comprehensive logging system, and a specific calculation formula may be expressed as follows:
wherein i represents the serial number of the slurry pump, D i Represents the diameter of a cylinder sleeve of a mud pump, l i Representing pump stroke, j i Representing pump valve number, SPM i Indicating the flushing speed of the drilling fluid pump, ef i Indicating the efficiency of the drilling fluid pump.
The integrated logging system may be configured with a mass flow sensor for acquiring drilling fluid mass and density to calculate a drilling fluid outlet flow, wherein the drilling fluid outlet flow may be a volume flow of the drilling fluid outlet.
S320, if the drilling fluid outlet flow is larger than the drilling fluid inlet flow, determining a difference volume accumulation result of the drilling fluid outlet flow and the drilling fluid inlet flow with preset duration.
If the drilling fluid outlet flow is greater than the drilling fluid inlet flow, the risk alarm system calculates a differential volume accumulation of the drilling fluid outlet flow and the drilling fluid inlet flow over a period of time. The preset duration may be set according to the drilling scenario, and may be 3 minutes, for example. The calculation formula of the differential volume accumulation result can be expressed as:
wherein t represents a preset time period, flowout represents drilling fluid outlet flow, and Flowin represents drilling fluid inlet flow.
In one possible implementation, the preset duration includes at least one data acquisition period;
if the drilling fluid outlet flow is greater than the drilling fluid inlet flow, determining a difference volume accumulation result of the drilling fluid outlet flow and the drilling fluid inlet flow within a preset duration, including:
if the drilling fluid outlet flow is greater than the drilling fluid inlet flow, determining the difference volume of the drilling fluid outlet flow and the drilling fluid inlet flow;
and accumulating the difference volumes associated with the data acquisition periods in the preset duration to obtain a difference volume accumulation result.
In the risk detection process, data acquisition is usually frequent, and the preset duration may usually include at least one data acquisition period. The risk alarm system may accumulate the differential volume for each data acquisition cycle. If the risk alarm system detects that the drilling fluid outlet flow is larger than the drilling fluid inlet flow, calculating the difference volume of the drilling fluid outlet flow and the drilling fluid inlet flow in the current data acquisition period. And finally, accumulating the difference volumes associated with the data acquisition periods in the preset time period to obtain a difference volume accumulation result. The specific differential volume accumulation result can be expressed as:
wherein T represents a data acquisition period, and n represents the number of data acquisition periods included in the preset duration.
The method and the device can simply and quickly calculate the difference volume accumulation result, and are favorable for realizing accurate detection of overflow risks.
S330, if the difference volume accumulation result is larger than a preset second overflow alarm threshold value, controlling the overflow alarm to alarm.
And if the difference volume accumulation result is larger than a preset second overflow alarm threshold value, the risk alarm system controls the overflow alarm to carry out audible and visual alarm. The second overflow alarm threshold may be a volume threshold, for example 0.1m 3 。
And S340, if the concentration of the harmful gas is greater than a preset concentration threshold, controlling the harmful gas alarm to alarm.
According to the technical scheme, when a risk detection trigger event is detected, at least one group of risk judgment data is acquired through the comprehensive logging system according to a preset data acquisition period, and if the risk judgment data meets preset judgment conditions, a target alarm is controlled to alarm through a risk alarm system. The scheme solves the problem of poor drilling risk alarm timeliness, can maximally reduce drilling risk while avoiding alarm delay, and ensures exploration benefits.
